Solving the Annoying Flashing Input Menu on Insignia Televisions

Solving the Annoying Flashing Input Menu on Insignia Televisions August 21, 2012

My blog is usually about other things, but I have occasionally been able to offer useful technical advice. My solution to the problem of experiencing a black screen after login on Windows Vista remains one of the most viewed entries of all time on this blog.

(My post on the most effective squirrel baffle of all time has not gotten nearly as much attention – even though it is free!)

Anyway, I own an Insignia flatscreen TV – not a large one – and for some time it has had an annoying glitch that I learned, when searching online, others have also experienced. The input menu – i.e. the menu that lets you choose input from DVD, HDMI, VGA, etc. – would just appear on the screen, sometimes flashing on and off, sometimes staying there for a few seconds before going away, sometimes doing any or all of the above for long enough for it to interfere with what I was doing.

Today I fixed it, eliminating the problem, hopefully forever. And so I wanted to share the solution.

When I looked online, I found only two suggestions other than “Take it back to the store for repairs” and since it is not an expensive television, that would be liable to cost enough to make it preferable to buy a new one. I am actually using this TV as a monitor on my computer, and I wanted to see if I can keep it working. When it is your computer monitor, having an annoying menu pop up frequently and at random is at least as irritating as when it happens when you are watching a show.

One suggestion was that it could have something to do with the remote control, especially if its batteries were running out. I quickly eliminated that as the source of the problem.

The other suggestion was that it had to do with the panel with buttons on the side of the TV. This was confirmed as the source of the problem when I discovered that, when I pushed the “power off/on” button, I would sometimes get the input menu rather than the result I was expecting. Clearly something was amiss with the buttons.

The suggestion was to clean the contacts, but since buttons on a television are really a redundant feature in our day of remote controls, I decided to do something more drastic but much more likely to work. I removed the button circuit altogether. And since then, the input menu has not appeared.

Here’s how I did it. This should not take more than 5-10 minutes.

First, disconnect the TV from the power, and lie the TV down face down flat on a soft surface. A couch works, since you can have the base stand sticking off – just remember to dust it before you do that.

Second, remove all the screws from the back. There are around 10 including those from the base stand, and they all should come out fairly easily.

Next, use a screwdriver to gently separate the front edge cover from around the TV screen itself. This is really the last thing preventing you from getting at the circuit that is causing your grief. It does not come apart without inserting a screwdriver, and you don’t want to apply so much force as to break something. It is a matter of a plastic cover that snaps into place, and so you will need to work your way around the TV with the screwdriver, angling it until the next snap is undone, and then next, and the next, until you can separate the front edge cover.

At this point, you should be able to get beneath the power, input, channel and volume buttons which are on the side of the TV. Beneath the black cover panel with the buttons, you will find a small circuit board with buttons in it. While you are welcome to try cleaning its contacts (someone recommended using alcohol), I simply removed it. I unplugged the power connector and took the circuit board out in its entirety, using some masking tape so as to not leave the power connector rattling about loosely inside the TV. I then put the cover with the buttons back, so as not leave an empty space there, snapped the front panel back, replaced the screws and screwed them in, and reconnected it to the power (and in my case to the computer, since I’ve been using it as a monitor).

The input menu has not popped up since.

Now of course you will need to rely on the remote control for turning the TV on and off, changing the channel, and lowering or raising the volume. Can I safely assume that most people were doing that with the remote anyway?

I should add as a disclaimer that I am not an expert in repairing televisions, and am in no way responsible or liable if your own experience in attempting to fix your TV is different than mine. I am simply sharing my own experience. You must use your own judgment when evaluating your own skill in carrying out the procedures describes, and dealing with any differences that might exist between your TV and mine or the problem affecting your TV vs. mine.

If the solution I described in this blog post worked for you, please leave a comment to let me know. And if other models than mine are different in some way, and so you had to tweak how you implemented this solution, why not leave a comment so that others can benefit from your insight?

    Thanks!! I have a 46 in with same problems. Tried several times other methods but yours worked. Left board in there to have a backing to allow buttons to stay out. Just disconnected wiring for both ends and used electric tape. Saved hundreds of dollars!

  • Brian W

    I have a 47″ with the channels changing constantly. I tried your method and it worked just fine. The TV has been running now for about an hour, and no probs.

  • dr who

    didnt work for me. thanks for the help though.

  • Paul

    Thanks! I was just about to buy a new main board when I read ur post. Did exactly as u suggested and unplugged power strip, problem solved. I concur, no need for direct buttons when all we use is remote. Worked like a charm, 52″ insignia LCD.

  • suzieq

    It worked on my 19 inch. I refused it throw it away!

  • je

    Cleaned the contacts, it worked.

  • Weekofmondays

    This would work, except that my remote stopped working and the universal remote won’t work for all of the features, and things like changing from the bluray player (hdmi) and over the air tv….

    • What a pity. I take it it doesn’t have an “input” button, or at least, not one that works with the TV?

    • noemi

      If you have the cox cable control that has a input if you have century link remote push the tv button and then the the tv/video button located at the top right hand that will change it to tv, av, hdmi what ever you are using

  • akshon

    took me an hour, but I unplugged the input button panel on the tv after removing the back screws and bending it enough to reach back there and pull it out. Tv works perfectly now…I guess those panels only last a few years before they go turbo!!! 🙂

  • auntie p

    Thanks – we followed your instructions and disconnected the power supply to the buttons on the side, worked a treat! Ours is a bush Tv btw. Thanks again!

  • R&R

    Thank you so much! It worked like a charm. I just unplugged the circuit board and taped off the wire instead of removing it. You’re a genius!

  • Charlie

    Sweet fix! 36″ Insignia. The hardest part was unsnapping the back cover, but after that, it was a breeze. You, sir, are a genius! My sincere thanks to you.


    Thank you so much……i did it and the input flasing went away…..A+

  • Qlidnaque

    i have 40 inch insignia tv that i’m also using for my monitor. The input menu popping up gradually got worse and more frequent so today i popped open the lid like instructed, and instead of removing the chip, i just cut the blue and white cord connecting the manual buttons to the motherboard. problem solved. 🙂

  • Guy

    Thank you!


    Nope didn’t work for me but mine started after a thunder storm. The cable box hdmi stopped working and the tv started this crap.

  • Nits

    Thanks a lot. Exactly the same issue on my Bush HD ready. Detached the cable from side control buttons and no more switching the sources. Saved me from buying a new TV, just that now I have to rely on remote. Anyway, I dont remember ever going to the tv to change the channel.

  • bapman

    Same thing on my insignia 22 or 23 inch. I had not used the computer for a few months and thought I had better update that computer which I also used and always used that TV as a monitor. When I tried to turn it on the remote was not working so I opened the battery compartment and move the batteries and then it worked. First I noticed the batteries were corroded and I replaced them but then when I started to work on the computer it had that damn box that said VIDEO4 VGA kinda flashing or flickering and it just would not go away. I tried to reset the TV by unplugging and draining the power but no success. I also tried holding the input button for awhile and it would go away until I stopped pressing the button. Also the remote did not work for anything except the power button but when I pushed the input button and held it in on the side I could use the remote somewhat. Anyway sorry for rambling on, I took it apart and disconnected the side buttons and taped the lead down and now it works fine with the remote and no more box with VIDEO4 VGA on the screen constantly. THANKS !

  • Shayna

    Thank you so much!! This just worked on my Insignia 46′. It was the Settings menu that kept popping up. Followed your instructions and hasn’t happen for almost an hour.

  • SO

    Now does this work with all television sets. Because I have a Seiki 32″ flat screen and the input menu comes up and goes away every 5-10 seconds. And it gets anoying.

  • Linda

    Hi, Just finished following your suggestion on my 2 yr old 32″ Westinghouse LCD. So far it worked. Couldn’t completely remove the back so it ended up being a 2 person job. All I had to do was unplug power source. Thanks!

  • Auburn

    This fix worked great for my 55″ Insignia. Thanks!

  • TM

    Thank you!!! Neighbor’s 27 inch Insignia TV was flashing HDMI 5 and wouldn’t quit. Took off the back (remove all the screws and standf and don’t forget the 2 screws where the HDMI and other outlets are located) prying it off gently all the way around with flat head screw driver. Simply unplugged the button circuit card at a small tabbed connector at the top right the buttons circuit board. Just lift it up, or press it down which ever way works where the wires plug in to the buttons assembly. Tape the connector down out of the way so you can close the back by pressing it down all the way around as you hear the clicks locking back in place. Screw it down again. Worked like a charm.

  • thisisendless

    Yes! Thank you! Although I couldn’t get the back of the TV all the way off, so I had to separate it just enough to put my hand in there and unplug the panel. After about 30 minutes and 3 outbursts of loud swear words, it now works fine! No blinking. Thanks so much! I didn’t tape anything down though, does that matter?

  • Bo

    Thanks!! Bush lt32m1ca, removed power to input buttons worked a treat!!! yey!!

    • TJ

      Hey guys this happened with my 32″ Insignia and all I did to fix it was disconnect the wires that led to the buttons on the tv. No taping, no cutting, no nothing and it worked! 1 connector from the on tv buttons to the circuit board. Hope that helps as well!

  • Hi

    Bless u , I did it exactly like you said and it worked no annoying menu popping in the middle of my show.Thanks.

  • Gillis

    Hello ! got a 39” but disconnect the one from the side of the tv , still the same 🙁
    witch other cable should I disconnect THX

  • Terre

    I want to say Thank You for your blog, Our tv finally fixed. I called the manufacturer and they can’t help us. Thank you so much again.

  • Javier Stoltz

    I have a bigger flat screen Insignia and the main menu would do the same thing all of all sudden. Took the back off, disconnected the side button panel, put the back on, and no more issue. Thanks for the idea.

  • d1no

    Wow.. Thank you so much. The issue with mine was the input menu was coming up and then just continuously cylcing through all the inputs on the list, not stopping at any. Seems to be more or less the same issue. Read your instructions, also quickly determined it couldn’t be the remote, and took off the back as you said and viola! No longer happening!! I simply unplugged the power connector to the little board that the controls were on (mine were the STUPID touch style buttons, not sticking out you just rub your finger over). Thanks again, this was most definitely the problem. I wonder if it’s simply some dirt or dust in there causing them to think they’re being pressed?

    Thanks again!

  • Pavan Kumar Kota

    I unplugged the power connector and took the circuit board out…

    How did you unplugged that white connector there? I couldn’t do it. Can I cut those wires and use some masking tape?

    • You should be able to unplug the white connector. I would recommend doing that if at all possible.

  • Louis

    Just removed the white connector, put the cover back and good as new. Thanks

  • Valerie Nelson

    You Sir, are absolutely awesome. Just a couple notes, my tv is Envision, I followed your suggestions and noted a couple differences, trying to remove the front bezel was Not working, when I flipped my tv over, it was the entire Back panel that came off. the plug to disconnect was black, not white. Same principle. I unplugged the power panel, and reconnected Tv Before putting it back together and it worked fine. Just for fun, I plugged the panel back in & immediately problem recurred, Confirmed the power panel is problem. Put all back together & everything is fine using remote. I pulled out the power card, and ideas where to get a replacement? Assuming I wanted to completely repair tv? Thank you for sharing, I am so glad to fix tv and not throw away the current one, since I have no $$ to buy another. Thank you, thank you, thank you

  • Bootpdx

    My TV is doing this but I noticed the circuit board for the buttons is not plugged in, but hardwired. Do you think it is ok to snip the wires to the board? This flashing menu is driving me and my kids insane.

    • Only one way to find out…

    • Bobsk8

      There are only two wires to that circuit board, so just cutting them does the same as unplugging ( you could even cut one of them and get the same result.

  • Tim Kolnik

    Thank you for your post. I just fixed my tv in just a few minutes. Very easy fix. Thanks again

  • Bobsk8

    That fixed it. I have a 50″ Insignia about 4 years old, and sudden;y tonight the menu started popping up. Took off the back screws, and just pried the front in the area where the control switches were, unplugged the connector to the little circuit board with the switches on it , and it is fixed. Thanks.

  • Laken

    So thankful for people who take the time to put these things on the internet! I was very close to throwing this TV away and buying a new one before I came across this post. My input menu/main menu/volume were controlling themselves and flashing on the screen constantly, the TV was unusable. I just simply unplugged that side button panel inside and it hasn’t done it since!

  • Iain Rosszell

    I experienced this same random rapid ghost input craziness with my RCA TV (and it was getting more frequent/more annoying!), considered your logical conclusion as to the cause of the problem (gotta love the logic!), proceeded to easily disconnect the cable connection to the manual input panel and voila – defective/redundant piece of hardware out of commission and my otherwise perfectly good TV salvaged! Thanks very much JFM!
    My addition to the discussion is that in the case of my particular TV design, only the screws related to the casing portion of the rear of the TV which included the input panel needed to be addressed, and even then, I found that it was only necessary to remove those screws that impeded my ability to insert a finger and apply a small tug to the white cable involved (so do not automatically assume that, for example, all the perimeter screws will need to be removed in order to effect the required disconnection)

  • Jennifer Wizner

    My large Insignia is doing the crazy input button scrolling. I can’t get it to do anything else. Took a lot of time and took out all the screws yesterday. Was able to get to the circuit board for the buttons on the side of the TV but there wasn’t any visible way to disconnect it so we cut the wires. Sadly, it didn’t fix it. Has anyone else had any luck trying anything else before I give up entirely and buy a new tv?


    Thank you!! I just did this fix with a 1 year old Insignia 40″ flat screen. The button panel on this tv did not exist except for the input button which was attached to a small circuit board. I just cut the cord to the circuit board input button. Took me about 30 minutes but that was mostly taking out and putting in screws.

  • jessrose21

    Thank you so much! I have a Vizio flat screen from 2011 and was getting the flashing input menu. We took off the back, unplugged the power buttons’ white connector, and no more flashing! It works just fine now with the remote control. Only bad thing is now I have no excuse to buy a smart TV! 🙂

  • Smileyfacesammie

    Thank you so much!!!! This fixed my problem and saved me a ton of money.
