1 Answer

No picture or sound


Remove the rear panel. With the TV on you should see a red LED near the center of the PCB. There should also be 5 green leds, 3 to the left a 2 behind. If there is no red leds, check the fuses. If there are no green leds or maybe 1 or 2, disconect PSD5. It's a connector on the left side of the power board that connects to the audio board. It's the 3rd on fro the back. It's labled. With that disconected, turn on the set and look for the green leds. If all 5 light, the power supply is OK and you have a problem beyond that. If they don't all light you have a bad power supply.

(Hitachi 43F300) Turning its self off


Sounds like it is going into shutdown mode. When the TV power supply and system control sense an overload the system control turns the TV off to prevent further damage from happening. I suspect it is a shorted convergence IC. It would be best to call a service center to repair the TV.

No clue


Sounds like failures of the convergence output IC's. They should be STK392-110's in the set. Also check associated circuitry around them.
