SOURCE: tv won't turn on -no power
Power supply problem.... I can explain to you how to fix via email with detailed instruction and pics... Hope you haven't bought another as this is a 5-30 dollar fix. I have 2 50" that did this I fixed mine for 80 cents.
Marine on a mission to help ppl fix their spendy sets and not waste their time and money spending hundreds of dollars on a 2 dollar fix.......

Check all the caps on PSB. if any look puffed , replace them. If you are getting 14volts to the ivnerter board PS is good and the inverter is bad.. good luck

Most likely the TV has a power supply related problem. It's possible that it maybe a bad capacitor or transformer on the power supply board. Or, something simple like a blown fuse inside the TV.
But, I can't say it's 100% the problem because I can't actually look at the tv over the internet. I can only make guesses with the symptom.
You have a few choices:
1. If you have some electronic experience, if you can find and purchase a Service Manual over the internet; It will help you diagnose the source of the problem and fix it by soldering in the new part. The Service Manual will give you circuit diagrams, test points, and part# lists.Usually, cost under $20. And most cases the new part cost less than $15.
2. Pay a TV shop to do the repairs. It maybe costly, but get an estimate of how much they will charge. That way you can decide if it worth repairing or replacing the whole TV.
I hope I shed some light on the subject for you.
