This is most likely a couple of problems inside the unit , will you be trying to fix it yourself?
if so give me a fixya rating and I'll be glad to assist in determining the source of the problems

    this is going to be one of the boards and you will need to do some tests for me so I can analyze the results

    you will need to check for open protection fuses on the power section and check the voltage on the transformer

    when you get the results post them so I can analyze them , thanks

WHY WON'T MY HITACHI PLASMA TV SHOW PICTURE OR SOUND? WHAT DOES THE BLUE LIGHT ON THE FRONT FLASHING 4 BLINKS MEAN?


These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices.

If blinks continue without any pause, the main board is faulty.

Following a audible pop TH 50PZ85U will not power on.


Most common thing to happen is a capacitor went bad on one of the circuit boards making the loud POP sound. Odds are it's on the Power Supply Board if the TV isn't showing power at all. The picture below what a bad capacitor looks like.

They range from different sizes and color. Swollen, deformed, and raised top is the thing to look for.

Solder in a new capacitor on the board or replace the whole circuit board.

Display IC seems to have gone. It will be a replaceable module. Only you have to figure out which one it is. Such thing happen in electronics. Look for any burnt or bulged IC.

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.
