My Hitachi plasma P50S601 turns on for a second then goes to a black screen and then a blue light flashes 3 times and continues until un pluggeed ?????

Hello. If the TV is actually making a picture, then goes black, I would try the Y Main board. If it never makes a picture, one of the ICs on one of the Y buffers will have a hole in it. If the latter is the case, finding the part will be next to impossible. Sorry... Good luck.

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

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.

This web page may help it has links telling you what to test. http://www.hometheatershack.com/forums/hitachi/30302-p50s601-blue-power-light-flashing-3-times.html like if your power light is flashing 3 times then it most likely is two caps in the power supply and one of the sdr boards.

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.

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]
