Re: Insignia NS-LCD26A will power on for a few minutes then shut off
Well the TV was alive....but after putting everything back together it will now just play audio with a blank screen and backlight on, and will still shut off on its own after a few minutes. I am toying with the idea of replacing the main board which is at least part of the problem and maybe the power supply, but would cost about $60. Does anyone have any input on if its worth that? Its a 2007 TV and a cheap 32 inch led can be had for just $40 more now.

Re: Insignia NS-LCD26A will power on for a few minutes then shut off
quick update, powered the TV on and put heat gun on over the heat sink the picture came on almost immediately, seriously in about 5 seconds. Letting the board cool over the next 30 minutes to see if it lasts. I've seen other threads and know this is likely only a temporary fix but at least I know its a main board issue.

thanks for the reply, I do not have an oscilloscope but do have a multimeter and will try to heat the main board to see if reflowing will do the trick. I'm assuming the main processor is under the heat sink and not to the right of the RF unit.

Insignia NS-LCD26A will power on for a few minutes then shut off
I inherited an old LCD TV from a family member and was hoping to repair it. The previous owner complained that it would turn on but only sound would come out for about 20 minutes, then the video was visible. I have never seen the video myself since the unit will power on with the backlight on but then power off randomly a few minutes layer. Because the power button and ccfl lamps work I figure the power supply and inverter are functioning properly. There are no obvious melted boards or swollen caps visible. I tried reseating all connections but no symptom resolution. I can't even see the on screen...

Re: New Members - please post your introductions here
Hello I am am a Veterinarian by day and an amateur tinkerer by night. I like the challenge of trying to fix old electronics that other people assume are broken beyond reasonable repair. I have an Insignia NS-LCD26A as my current project and was able to bring a westinghouse 47 inch lcd back from the dead after a failed firmware update. I have minimal skills with electrical engineering but always love to learn!
