My problem turned out to be the D board. I purchased one on Ebay for $100, replaced myself. The service technician charged me $90 to come out and tell me the problem then wanted $700 to replace the board.

Ouch...ok a one blink code could be either the P (power board) or the SC (scan board)...only a service tech call can tell you for sure. Ask around for some quotes first.

Plasma tv th-42pd50u not come on and keep blinking red light two times and then stop again blinking red light two times and then stop not come on


The light blinking twice means there is a fault within the system and it is a code to tell Panasonic where roughly the fault lies.
Go to Panasonic's web site and look for your set then input the fault code and hopefully they will tell you where the fault lies.

Oven will not bake but everything else works fine


What is the red light blinking? Count the blinks before it pauses and post back here. It'll give me and everyone else a starting point.

TH-42PD50U 42" plasma from Panasonic. The TV tipped over and won't turn back on. The red power light just keeps flashing on and off.


Try to unplug and replug the power cord. If TV remains unchanged you need to call for service. The power supply board was defective. In worse case, the Y and buffers are defective, too. There are many steps needed to figure out the exact defective board. You need help from TV repairer unless you want DIY.

No power


If your model number is TH-42PD50U, It is very hard to diagnose the symptom.I can direct to you where is the possible cause is.
For 7 blinks pattern may have trouble with SU or SD board or it could be SC board or Power Supply

Power light blinking 2 times


2 blinks means the unit is having problem with 12 volt supply.
while power on you can check 12DC on power supply before shutdown.if the voltage is constant before shut down I would recommend to replace D board.
