When this happen, it's because it usually get an electrical overcharge, damaging either the Y board or the Z board. This is kind of difficult to figure out so my suggestion is to get a professional. It can be fix.

SOURCE: Panasonic Plasa TV's Power light is blinking no pic no sound

The most likely the TV has a power supply related problem. The most common thing to go out is the circuit board that supply power to the screen. Commonly called a Backlight Inverter Board.
I can't say it's 100% the problem because I can't actually look at the tv over the internet.
If by chance the TV is still under warranty, go that route.
If not under warranty and If you have some electronic experience, you can purchase a Service Manual over the internet and diagnose the source of the problem and fix it by soldering in the new part. The Service Manual will give you circuit diagrams, test points, and part# lists. Usually, cost under $20.

I hope I shed some light on the subject for you.

SOURCE: Panasonic plasma th42ph10uk power red light blink twice

Manual says problem with SC, SS, or C boards. SC is large board at left when facing rear, SS is large board at right, and C is small long board at very top. You could check fuses on SC and SS. Also, SC and SS should make a buzzing noise(not too loud) if operating. If a fuse is blown, suspect that board is bad not just bad fuse. Search parts at encompassparts.

SOURCE: my tv does not turn

A blinking light on your TV means it is on face mode because one of your parts is shorted out and the TV is protecting the other parts. I don't have the service manual for this TV but on the older Panasonics 2 blinks poited to the D board. You can do a search online for a service manual for that TV therir are a few retailers selling it. The D board is also know and the Logic board which is located under the signal board. On This TV I belive the logic and signal boards are just one board. You can get parts for this TV at www.interliquidparts.com

This sounds like a main power board issue. After you unplug it, it will work? Are you planning on trying to service it or having it serviced?
Thanks,

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.

I have a Panasonic 53" PT-53x54- 53" turns on for 5 seconds then


It is very common for the high voltage tranformer or flyback to wear out and not provide adequate power to the tv. You can test them with an ohmmeter to see how much powrer is being sent to the main circuit board. You can get parts at tigerdirect.com

Panasonic TH-42PX80U won't turn on.


You are missing 15volts. If this is a new TV, it could be as simple as a plug not fully seated on the power supply. Regardless, the repair should be covered by warranty and Panasonic is one of the best when it comes to taking care of the customer. Ifd nI can be of further assistance, let me know
