It started with the source select button shutting the tv down and making it impossible to get back to the correct input if it was changed. then it would shut off on its own and i would have to wait to turn it on now it wont turn on at all i have first year electronics and am an automotive mechanic including electrical i just need help narrowing down the problem to a few simple change outs before i take it to a tech. a friend said his had a resistor go out i can change that so dont want to pay to have some one change a small component but i have limited test equipment basically i have a multimeter and not a good one any help you could give would be great i have tried unplugging it to reboot it hasnt worked thanks
They only way to really narrow down a service problem such as a dead set would be to first get a downloadable schematicfor like 20 bucks, I have seen them even less expensive! Then start troubleshooting the power supply to see if the SMPS is functioning or shut down because of excessive current draw or a short circuit somewhere else in the set. If you get a schematic and need a hand I will be happy to point you in several spots that need to be checked first BUT you must be aware of the HIGH VOLTAGE thats stored inside these sets even when they are unplugged,, If it bits you, You will know it!! believe you me!!! Good Luck

I have the same problem, it all started when I had to unplug it to shut it off. Well tonight I was watching TV and it just blacked out completely with no sound then now it won't turn on at all. It is like it isn't getting any power at all. What can I do.
