Question about Hitachi Ultravision P50S601 50 in. Plasma HDTV

2 Answers

No Picture or Sound, Blinking blue light

I have a 50inch Hitachi plasma (p50s601)the other night it went black and the blue light flashes 3 times over and over. I opened it up (It is out of warrenty by 1 month!!!) and the SDR-U board was smoking. I got a replacement and installed it (super easy!) but it still does the same thing! The local repair guys want $200 to just look at it and that doesn't go toward the repair. I have the service manual but it doesnt tell me if there is a reset button or what else could be wrong. HELP!

For more info on this set please check out The p50s601 is almost the same as a p50h401 but doesn't have the power swivel stand. http://www.hometheatershack.com/forums/hitachi/38229-hitachi-p50h401-led-flashes-3-times.html
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.

Hitachi tv turns on then gets bad picture than turns off blue light blinking


The name of the part is probably "buffer board" and there are two in your TV - upper buffer and lower buffer, also called SDR-U and SDR-L boards.

Those are the two most common sources of problems in P50S601 along with the Y sustain board (SD board in hitachi and Panasonic terminology), which sometimes gets damaged by the failed buffer board.

In the buffer boards market there are all kinds of offerrings. There are old buffers for around $130 for the pair and there are new buffers in the range $160-$200 for the pair.

In my opinion if the difference is barely $30-$40 one is better off going for the brand new ones.

Here's a link to our title for them, you can sure find others if you start from it:

My hitachi p50s601 turns on for 1 second and then goes completely blank and the blue light flashes 3 times repeatedly.what do i do?


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

My hitachi plasma tv model P50S601 only flashes a picture for a second before going black. Once it goes black, the blue power button flashes and can't be turn off by the remote or by manually pressing it...


These tv's are know for this. I have a topic about it telling you how to test and repair these at http://www.hometheatershack.com/forums/hitachi/38229-hitachi-p50h401-led-flashes-3-times.html

p50s601 and p50h401 are basicly the same tv but the p50h401 doesn't have the swival base.

these sets are known for two caps to go bad in the power supply and then most likely it fried out one or both of the driver boards. the driver boards can be repaired. a company that repairs them is listed in the topic. or you can buy new driver boards.

Blue light blinking-


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 milleniumtvsvc@gmail.com

HITATCHI ULTRAVISION P50S601...POWER LIGHT BLINKING...WONT COME O


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

If you want to repair at your own expenses, just locate any good qualified repairer.
