I think you have problems with the digital main PWB.

If the power PWB failed, turn off and change the pilot ligth to red.

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.

The Blue Blinking Light Hitachi.

When the light blinks 4 times it means you can possibly have 4 problems with your plasma.

1. X-Sus
2. Y-Sus
3. Power Supply
4. Sdr U or D

A good way to determine if you can fix this problem yourself is if you can build a PC. If you cant this can cost you upwards of 600$ to fix.

First get a flat area and lay a soft blanket down and lay your TV down so the back is up. Then goto your PC and goto Google and type "P50T501 Service Manual .PDF" you can buy it or if you look hard enough you can get it for free. Next in the service manual it will have a diagram of the Circuit Boards and their locations. Take the back off your Plasma and check the 4 boards. Look for burn marks, cracks, smoke mark. Take your time and look closely. When you find the broken boards unplug it and take the part number and find the replacement online. Plug it in and you should be good to go.

When i had 4 blinking lights i had to change my SDR U and D boards. They cost 100's a piece for Refurbished boards. Keep in mind im a contractor not a techno geek, and i was able to diagnose and fix my problem rather easy.
