Was watching my TV a few days ago. There was a loud pop, the screen went blank, and the TV powered down. I first thought it was the bulb, which has never been replaced, but now I am not so sure. Symptoms: when I power on the TV, the ON button flashes green. After a few seconds, there is a very fast metallic clicking sound for about 5 seconds, which repeats after another few seconds. The cycle repeats itself about 20 seconds later. The green light keeps blinking but I never get sound or picture. Any ideas? Bulb? Ballast?
Hi, It could well be the power supply that is in the back of your set. Have a repairman check it out. It's not a do it yourself thing. Good luck.

Most problems with TV not turning ON is a power supply related problem. The relay click are a normal process that powers up the circuit boards. Right now the TV is most likely in " Protection Mode ". The TV detected a bad circuit board and it will prevent the TV from fully turning ON. This keeps the other circuit board from being damaged. The power light blinking is a code.
If by chance the TV is still under warranty, go that route.
If not under warranty and If you have some electronic experience, if you can find and purchase a Service Manual over the internet. This 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, blinking light codes, test points, and part# lists. Usually, cost under $20.
I hope I shed some light on the subject for you.
