Question about Vizio P2 42 in. HD-Ready Plasma Television
My Vizio 42 inch made a loud cracking sound and then the picture went out. I still have sound but the picture won't come back on ?
With all the listed sets,itis most likely the y-drive(sus) board.The only problem is that this board usually fails when the horz.buffer ic's fail,which is usually part of the plasma display.This was a semi-common problem with this set.The best bet is to find a new set,since the parts alone will exceed the cost of a new one.Pioneer or nec seem to be the most reliable that i have seen.

Vizio very well know that this is a problem with their units. I bought my Vizio P50 in 2006 two months later it was out with the same problem everyone is experiencing. They replaced it under warranty and just before my warranty was over this month, guess what, the same problem. Vizio have refused to assist in solving this issue yet they know its something wrong with their plasma screens.

SOURCE: No picture but has sound
Regarding the Plasma TV with dark picture, this is often caused by bad sustain board, replacing the Ysus Zsus kit may solfe the problem.
Regarding instead the Vizio with sound but no picture:
If an LCD TV has sound but no picture do the following:
Use the source button to ensure that source is not set to the wrong input.
Try unplugging power cord for ten minutes, to ensure it is not a setting problem.
Check all the video cables at the back of TV.
Check Light /Color settings.
If problem persist and does not depend on external receiver or settings, then it is likely an internal fault.
If it has sound but no picture then one of the following parts is faulty, and must be tested and replaced:
The inverter is the high voltage board that provides variable power to the backlight lamp. This is the most common. When inverter is faulty you can get no picture, or a very dim picture that can only be seen by pointing a torch light with a 45 degree angle on the LCD surface from very near distance.
The inverter must be tested by reading voltages with a multimeter.
The LCD ribbon cable/LCD display and connectors.
This is quite uncommon, but happens. If the TV had been hit or moved the LCD cable may have slipped out, or the LCD connector may be damaged.
The LCD controller board.
This is the board that controls the video signal, it is difficult to test, as there is need to read determined values on IC pins. To test this board you need to purchase a service manual and follow the troubleshooting diagrams on service manual.
Input/Output Signal boards.
This are the boards where you connect the video and audio cables, if a signal board is defective, then you may get no picture on particular inputs located on faulty board.
If under warranty contact the manufacturer ringing the number on the user manual.
If you want to repair at your own expenses, just locate any good qualified repairer.
