Its the problem in the capacitors and the--- ics--- on the main power supply boards.as some of the caoacitors and --ics--- are blowned out or bulged up on the board and not supporting the tv to start normally.so please check the board and get the faulty one replaced and also check for the blowned out fuses on the power supply board.as the blown fuses can also cause this problem.

TC-P42ST30 power light blinks twice,replaced power supply board,no change.What to replace next?


Are you SURE you get 2 blinks? I show NO 2 blink code in the 011 model Pana plasma sets. Anyway...if you replaced the PS board and still get a code, unload the VS supply from the SC board and re-check--see if the VS supply comes up--even for a couple of seconds...about 205 volts or so. If it does--re-connect and see if it then does not come up. If not--then the SC board is likely bad (THE most common failure on ANY plasma set is the Scan board ).

Mitshubishi plasma tv ws65869 wont start green led on in a sec off


Not a Plasma by the model number listed.

When green power light comes on and goes off a few seconds later:

Press and hold on the front of the set both the Menu and Input (source) buttons at same time for at least five seconds and let both go.

Power light will blink a two digit error code like: 2 blinks, 2 blinks and a pause and repeat it several times.

If set has been unplugged it clears the errors and you must turn on and when power light goes out repeat.

Let me know error code found and I will help

Standby light keeps blinking. tv wont turn on


If the TV goes off completely, then is usually a faulty power board.

If the TV goes in standby, then it is in protection mode.

Ensure also that the fault is not coming from a faulty receiver box sending
bad signal, check if you get same problem on DVD with no receiver box
connected.

Try first leaving the TV power cord unplugged for some times, let say one hour or so.

The flashing light indicates a diagnostic state called protection.
When the TV goes on protection there are only two possible causes.

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 , starting the flashing light.

If you are in situation one, then the TV 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.

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.

On LCD Pay particular attention at inverter and power board, power board can be inspected looking for bulged or leaking capacitors, then tested with a multimeter. The inverter is more difficult to test , there is need to read voltages, should be done by a tech. Also the LCD controller board can cause same problem

On Plasma, test Sustain (Ysus/Zsus) / Buffer boards , cables to plasma, digital board and power board.

On Rear Projection : check lamp, lamp ballast, power board, and convergence.

On CRT TVs, check ballast , flyback transformer, CRT, Tuner, Convergence.

I need help tv plasma phillips


Hello gruponapa,

This problem is linked to a power supply issue. The SSB is part of the power supply chain and will cause system failure if the board is defective. I have seen to many of these type of modular power supply boards fail. The shutdown circuit is detecting excessive voltage, and in the process of turning off the set it may have blown something else. I am begining to suspect a design flaw, which happens from time to time. I would suggest having a qualified TV repair person take a look at the TV and work on it.

I hope this helps,

Thank you,
