Tv fault finding

SOURCE: Hitachi HD 1080 has blue power light on but no picture

Press the reset button...it's on the bottom to the right (underneath the TV). Same thing happened to me.

SOURCE: only vizio light on

why should i tell you (fixYa) how i fixed the problem for free? You wanted to charge me for your info so i think it's only fair that i charge you for mines. I did figure out and solved the problem.

SOURCE: only vizio light come on then nothing. have to unplug to turn off

there a problem on power side.. chage the ic and the resistor going to ic and check also the signal diode.

I had the same exact problem as posted above. My 50" LG plasma was out of warranty for 1 year! I called the LG executive call center, and they were very helpful. They offered to pay for the parts and labor. They recommended a few local repair shops, and they set everything up for me. The tech came out within 4 days with one part. The tech had to come out one more time the following week, since more parts were needed for the repair. The Y sustain board, along with 2 adjacent parts that are required to be replaced as a set, and the power supply had to be replaced (parts alone cost just over $900). TV is like new again; I'm very happy with how LG handled it, and made what could have been a bad experience a good one.
