Tv does not turn on

If green light flashes more than 8 times, it could be as simple as repairing or replacing the power supply. Unplug the TV ,remove the back. Look for bulged or leaking capacitors on the power supply. Do it yourselfer? only if you have soldering skills, or purchase replacement board. remember, used boards are just as old as your failed board, buy new or rebuilt, Good Luck

Turn tv on. green light solid display, no picture or sound

The flashing green light is likely indicative of a self-test failure, indicating the TV has detected some sort of internal fault. With no picture or sound, one strong suspect is the power supply. Flat-panel TV's have an internal DC power supply that converts the inbound AC current, and when these fail, or are unable to supply a minimum level of power to the set, it can behave as you describe, providing only enough power for the green light to illuminate.

37PF9731D/10 - when turned on the tv power light remains green but no picture or sound. Just a clicking sound - like it does normally when swiching on from being on standbay. It reapts the attempt to turn...

The clicking sound is from the main power supply relay being turning on and off, it is driven by hte main board and it gets the power from the standby power supply board.
You need to check the main powwer supply board and the standby power supply board voltages.
Check the resistor in the main power supply board also

Or, just make sure to use caps with low ESR, 105c, high ripple current and long life rating such as PANASONIC FM or FC series.

It sure sounds like the mainpower supply problem, the power supply may be trying to turn itself off because it detects short circuits.

replace the sustainer boards should correct this problem. New sustainer boards may cause red and green pixilation. If this happen, replace control board and TV is as good as new.

Hitachi Plasma TV model P50H401

I think you have problems with the digital main PWB.

If the power PWB failed, turn off and change the pilot ligth to red.
