Question about NEC 42VP4 42 in. EDTV-Ready Plasma Television
Over night my TV's picture have turn really dark and pixelated in the center of the screen. TV says on this way between 1-5 minutes than turns off by itself. The green power light stays on through this so I have to manually turn off the TV and turn it back on.
The plasma panels operate on 170VDC and 60VDC, Sound like the 170VDC from the power supply is low or dropping low. You need a tech to look at it, the voltage sources are marked on the board and the adjustment is labeled. Typically a component such as a regulator or capacitor is leaking to cause the voltage to drop.
