Re: Insignia 42" won't turn on - gray screen

There are "manual" buttons but they are part of the IR board also. The power "buttons" on the side of the tv aren't really true buttons (I mean they don't click or move when pressed). I think they are some sort of "touch" buttons. But again they are all part of the same IR board.

Ok, main board then. What are the chances the IR board is bad also? I'm wondering if I should maybe replace that also. Or is there any way to test it?

Re: Insignia 42" won't turn on - gray screen

Tom, I ran the test you suggested. I get a white screen, then red, then green, then blue. Then it goes thru a series of scrolling colors. And then it repeats...

Is it the flat cable that goes to the main board (coming out the top in my picture)? Or the cable on the left that goes to the y-main board, or the cable on the right that goes to the x-main board? Or the one that goes to the power supply board? Appreciate the help!...

Hello all, I have an Insignia 42" TV (model NS-42P650A11). After a recent lightning strike, I was not able to turn on my TV. When I plugged it in, it would just click about 5 times and then shutoff. It never really turned on at all. Also, I was not able to use the remote or the touch buttons on the side of the TV to get it to do anything.

After inspecting the power supply board, I didn't find any bulging, cracked, or leaking capacitors. I measured the voltages going to the X-main, Y-main, and logic board, and they appear to match what is printed on the circuit board. So, I...
