Insignia 27 LCD tv that got a small static shock, now no picture.
When shutting off the tv it got a small static shock and now there is no picture. The insignia label blinks from red to blue but there is no picture. I would like to try and fix this myself if I knew what part was needed. Thanks for your help.

static electricity can damage the chips on the boards. it all depends were the static voltage went to, if it was just to the buttons controller board or to the main av board. you could need new button board or you could need to replace the main board and the button board its hard to say with static shock.
I would need more details on this problem. Does the tv turn on? If so, what do you see on the screen? If you mean by "zapped" that the tv received a lightning strike and does not turn on, it's possible there are several damaged circuit board components. Depending on the severity of the strike, it's possible that just the fuse is blown. I need more details to advise further.

Insignia Polaroid Advent Audiovox ISLCDTV32 lcd Tries to start then Shuts down! Insignia IS-LCDTV32 , Polaroid FLM2601 andFLM3201, Advent 203L32K50B Also Audiovox FPE 3205 LC32K5. Cure:Replace the three 680uf at 35 volt caps at the top left of the power supply board.
I replaced the caps--about a buck each. The bad caps were swollen, and soldering in new caps wasn't hard to do. THANKS!!!
if you want to eliminate magnetism, you have to degauss the screen, if you don't know how to do that, here is a small guide for that: http://www.wikihow.com/Degauss-a-Computer-Monitor
but that strange shutting down its the transistor... so your best choice is to send it to a repairman to change the transistor.. if you try to do that for your self, you could even get shocked with the electricity contained in the tv... even if its turned off and unplugged..
