Hitachi ultravision p50s601. The tv red light repeatedly blinks. When you turn the tv on, it powers on and then about 3 seconds later the tv powers off.

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.

3 Blinks means one of the buffer boards is bad. The way to test it is to unhooking one SDR board at a time, and see if half of your screen comes on properly. If the SDR-D board is bad the bottom half of the screen won't come on when you remove the board. Send it out for repair (less expensive then buying a replacement board) or search for a refurbished board. If your non technical provide this info to a service tech and ask for an estimate. Cost will be moderate. Hope this helps you. Jon

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.

It seems that your unit has some sort of  PSU fault, or a problem that is shutting down the Power Supply Unit, PSU. This happens so that no further damage, and possible fire will occur. 

Remember there are lethal Voltages inside TV's, and generally these days don't contain any "User Serviceable parts" like in the "Old" days, instead Board Replacement is all that is generally done. 

You need to take the unit to a reputable service centre/man and ask for a firm "Quote" for the work to be done.

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.
