Question about Televison & Video
The tv runs for about 10 seconds with good picture and sound but then turns off into stand-by, with the LED flashing 12 times repeatedly(I actually counted it).
The flashing LED is an indication code of a board problem. If the TV is shutting down after a very short period of time, it is an indication the something is heating up. To isolate the problem, you will need to purchase some freeze spray ( component cooler ) at your local electronic shop. turn the tv on and spray an area ( usall about 1/4 of the board at a time ) and try to isolate the bad part ( component ). By repeating this process after a bit of time, you should find the part thats bad when you cool the part and the set stays on until the part heats up again. Then simply replace the part and your good to go. Always use precautions when working inside a tv as the picture tube can have as much as 35,000 volts on it ( can cause bodly harm or death ). DON'T COME IN CONTACT WITH THE WIRE OR GET CLOSE.
Good luck and I hope this has helped
