Question about JVC AV-56P575 56" Rear Projection HDTV-Ready Television
Jvc av-56p575. When turned on, Screen is Blue with faint picture in background and audio is good, Then shuts down after about 5 seconds and blue power button flashes, Will not power back up unless tv is unplugged. Any suggestions?
If you get a faint blue picture, then two of the three CRTs (projection tubes) are not lighting up.
This may happen for different reasons:
1 The power board is defective.
A faulty power board that is not giving right value on higher voltage lines to CRT power board can cause the problem.
Power board must be tested at component level.
2 Two CRTs, or Two ballast boards have failed at the same time because of a wiring problem.
This is rather unlikely, but still possible, voltage to CRTs and Ballast must be tested before replacing power board.
The control board must also be tested, since ballasts are not directly connected to PSU.
The TV must be tested by a trained technician before eventually replacing the power board.
Here all parts for your model.
Here power board: SRP-9001A-M2-R.
