I have a Hitachi Plasma TV P50S601 red power on, but when I press power button the screen flash then shut down and the blue light blink three time then stop.Do you know the problem ?

Try this repair video on youtube, might explain:

Servicing by opening the back cover should be performed only by a qualified service technician.

it have short in some board have to checked by some professional.

Mine never turned on but the blue power light would blink.I disconnected the upper y buffer and got light on the bottom half of screen and the blinking stopped.I have the upper board on order and I think this will fix my problem.There is a blink code somewhere,just count how many blinks.Start pulling connectors from power supply and when it quits blinking you've found the one,could also be the power supply with bad cap.

very common issue for these sets! p50h401 and p50s601 are almost the same.

if will tell you how to trouble shoot this tv. these tv's are known for two caps in the power supply to go bad and they need replaced then you have to test the sdr buffer boards if they are bad you need replacement boards or you can send them off to be repaired.( Repairing the buffer boards is a lot less then replacing them ) the link for the repair guy is on the page. this guy also sells the repair on ebay but if you contact him directly i beleave the price is lower. just tell him you were send over by home theater shack.

probably needs new scan drive board along with upper and lower buffer boards. it wont be cheap and its best to have a tv shop do it.

I would say you are lucky to get a pretty fair price, sounds like a convergence problem- if the tv is a projection wide screen. worth the investment Julio [email protected]

The TV is on protect mode.

Try first leaving the TV power cord unplugged for some times, let say one hour or so.

Also ensure that the fault is not coming from a faulty receiver box sending bad signal, check if you get same problem with no receiver box or dvd connected.

If that does not work, and you keep having a flashing led on front of the TV, and tv turning off by itself after a while, that indicates a fault condition.

The flashing light indicates a diagnostic state called protection.
When the TV goes on protection there are only two possible reasons.

1The internal circuits are jammed because of electrostatic charges accumulating on capacitors, or because of a wrong voltage read by the main chip on your monitor controller board. this started the protection circuit.

2 The protection circuit detected a wrong voltage or abroken contact, identified an internal fault and kicked in , startingthe flashing light.


If you are in situation one, then theTV will reset just unplugging power cord for one or two hours,sometimes even minutes.

If you are in situation 2 , then there is an internal fault.

Common faults that can occur are a blown capacitor on power board, a convergence IC has blown, or a fault on Digital board.

Check also the video cable or any external connection cable, if the cable is shorting, or the connector is bad, you can get same flashing state because of the video cable.


If under warranty contact the manufacturer ringing the number on the user manual
