Question about Insignia IS-LCDTV32 32 in. Television

1 Answer

Insignia TV is acting wierd

My insignia will turn on if I press the power button. But if I press the channel up or down button the screen flashes black like it is going to change but then resumes the same channel. My remote is messed up too which is why i started using buttons. I reset the remote once and it worked fine for a few months, but now it wont even turn the tv on even with fresh batteries and a blinking signal indicator, before it stopped working it would use the wrong function for a button, like if I pressed 1and 9 for nineteen it would change to 39. Or if I hit the channel return button it would go to a random channel, like 0. It is just acting weird and seems to be stuck on vh1. HELP.

    I have a similar problem, If I turn up the volume on the remote, it turns the tv off. If I hold the remote backwards and point away from the TV it works. WEIRD!

    My 32 in insignia flat screen TV will not turn on either by remote or power button. I have unplugged it from the power and left it for a time, but that has not worked

    The power off/on works but none of the other buttons. It is is stuck on one channel. I don't have the original remote, but the universal I have does the same thing (power only). I was considering buying a new Insignia IS-LCDTV32 remote but it sounds like I need to replace the panel.

    Same problem. I said panel but I meant mainboard. I can't find the part. I was wondering if anyone knew if any of the mainboards are interchangable, such as, 782-L32K51-560E, 782-L32K51-560F, 782-L32K51-560D, or 782-L32K51-560C.

Insignia NS-51P680A12 TV won't turn on. I have a blinking light that I am sure is a trouble code, but I can't find the codes anywhere online.


Those blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices.

Sound is pinned at 100% output. Remote nor physical buttons on device are working.


If any of the buttons on the remote or tv work, then try going into the menu and turning the sound down manually.
