Question about Flat Panel Televisions
The stand by light keeps blinking and the tv wont come on.
SOURCE: trutech tv model #PLV16260
Heres what mine did:no picture no sound, when i hit the remote the indicator light went out....piece of crap is six months old, cant find any info on it, cant get a hold of anyone at Trutech.
So i took it apart, on the board that the power cord is attached to, i found six blown capacitors. There is also a big ass one in the middle of that board which looked ok but blew out the bottom.I replaced them, and im watching it as i type.
Its fairly easy but if your not comfortable soldering on a cheap circuit board, take it to someone.
I hope it helps, i think this repair will fix the other Trutech models with the same problems.

I have a Sony KDL40S2000 and three months out of manufacturer warranty my TV made a clicking noise similar to feedback in a bad sound system and went to black screen. The error was not recoverable and four blinking lights were seen by a technician. I bought the extended warranty from my store, so I was covered. After one month in the shop, the technician brought my TV back today and told me the panel was replaced which would have cost me 1000 dollars if I wasn't covered by the store warranty. I read on another site the four flashing lights can mean a bad inverter. I don't know enough about TVs to tell you if the panel and inverter are one in the same, I just know you need to get it repared if you get four blinking lights at a huge cost!

There is a real good chance that the lamp fan is not turning. If you look with a flashlight in the vent on the left side looking at the rear of the set and have someone turn on the unit, see if it spins. if it doesnt, the protect circuit in the tv will not let the set turn on. Replacing the fan will cure the proplem if it is not turning.
Hope this helps,

Try leaving the TV unpugged for 30 minutes so the TV can reset itself.
If that doesn't work, most likely the TV has a power supply related problem. The most common thing to go out is the circuit board that supply power to the screen. Commonly called a Backlight Inverter Board.
I can't say it's 100% the problem because I can't actually look at the tv over the internet.
If by chance the TV is still under warranty, go that route.
If not under warranty and If you have some electronic experience, you can purchase a Service Manual over the internet and diagnose the source of the problem and fix it by soldering in the new part. The Service Manual will give you flashing red light codes, circuit diagrams, test points, and part# lists. Usually, cost under $20.
I hope I shed some light on the subject for you.
