Question about Vizio P2 42 in. HD-Ready Plasma Television

2 Answers

Picture fades to black then reappears and repeats fades to black .

TV is P-42HD vizio plasma, type: sp42A vizio HDTV manufactured march 05. Picture when turned on comes up and immediately fades to black in about 2-3 seconds, you hear a click and tv picture reappears and repeats fading again. cycle takes about 5-6 seconds. Audio is not affected and continues throughout this cycle. I am wondering which module or board needs to be replaced. Have TV at Local TV repair (Alans TV in Bay City Michigan) who is reccomended on FixYa. He says no service manuals available. If I can get the part he can install it. Parts available at Vance, just need to know which one to get. Any help would be appreciated.

Maybe getting a solution to this problem doesn't matter to you any longer, but I purchased three of this same model at the same time and two of them have failed. One with picture and no sound; the other with sound and no picture. I'm just going to swap the components until I discover what the problem is. I'll post the results if I achieve success.

Is the sound ok. Yust the Picture. If both dissapear replace power supply board. That is the main big board with the most heatsinks on it. Main power gos from a switch board to main power supply.
