After 5 minutes of TV being on screen turns grainy with vertical lines red and green and volume turns up real loud and sound is static. TV does not respond to remote control or power button. Have to turn off power strip. Model is Ns PDP 32-09 I thought it was cable box Att Uverse so ordered a new box, but that was not the case. TV is only 3 years old.

I have this EXACT SAME problem with my Insignia 26" LCD TV. I was three weeks out of warranty when it happened and Insignia wouldn't do anything to help me. I brought it to three repair shops and each repairman said that they couldn't guarantee they could fix it even IF they got the right parts. Anyhow, the TV repairman had it for three months (getting parts shipped from Asia, repair time, etc.) and he couldn't fix it. He also told me that tons of other people have the issue and that Insignia is replacing their TVs under warranty. So, if your TV is still under warranty, call Insignia. You just have to pay for shipping and shipping insurance. Hope this helps!

1343 or 1005 are the codes - press the TV mode button and the OK button together - the release at the same time - the top row of mode buttons needs to blink twice - then enter the code - the TV button should blink 2 times - try the power and volume buttons - if it worked then be sure to press the ATT mode button again after so you can change the channels

Try 1864. It worked for a Media-Com remote, when none of the other codes worked.

the pic attached is an electrolytic capacitor, they come in different sizes and are usually blue, black and sometimes yellow. depending on manufacture.

most of the problems I have heard of tvs having problems with the electrolytic capacitors going bad. if you open the tv and see one of those swollen or leaking you need to replace them.
