42 inch panasonic plasma no picture red blinking led light

I have a 42 inch EDTV panasonic plasma tv that just went out. It is model TH-42PD50U. When you turn the power on the red LED light blinks twice then pauses over and over. I tried to unplug the back power cord from the TV and plug it back in. This worked once for 30 minutes and now it will not come back on at all. Can I fix this or should I scrap the TV?

This appears to be a very common problem with these models. It would seem that either a fuse, or cheap transistor within the circuitry is known to go out, leaving the consumer with just a blinking red light. If the product is still under warranty, you may wish to return it to the manufacturer, or contact a local repair shop to have it serviced. this may be cheaper than actually buying a new tv. From what i see, the average cost range for repair of this problematic circuit board can be anywhere from 175$ - 35$ depending on what part is faulty.

I hope this has been helpful to you.

Hi there,

Please see here: PARTS FOR TH50PHW3
Please scroll to the part number. There are many parts that interchange between chassis.
Since you do not have a schematic for your set you will be hindered greatly with regards to repairing your set.
Since it seems that you are new to the television repair process I recommend bringing your TV to an experienced technician.
I am going to opt out of this question as I do not feel comfortable risking your safety as these units can be deadly if you do not know what you are doing.

Regards
all-guru

The usual cause of this Pixel generation circuit fails, this is part of the main board, about a $400-600 repair.

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.

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.
