It sounds that the Y buffer board has the fault. Repair to plasma TVS is really a skilled work. For more information, check the link ttp://electronicshelponline.blogspot.com/

The 7 blinks indicates that a failure has happened within the Y main and the upper and lower y drive panels. I recommend you taking it in to a Service center for and evaluation.

SOURCE: panasonic viera tv won't turn on. Power light

hello, you have a either your su, sd or sc boards fualty and it is a driver sos1 thats what the manual reads the best thing to do if your not electronically inclined or able to fix it is to get a service manual and make sure it is for your specific model and size you will find what the 7 blink codes mean, on my side i have a 42 in pana the service manual for this set and your is similar so since it is not the same model i cant tell you exactly what the truoble is but your best bet is to find a service manual find the 7 blink fualt then without getting ripped off you will know what the service man needs to do if you dont know or cant replace the parts yourself that is besides having to download firmware from your computer to a sd card and update your set but you need to solve the blinking code first it may solve the entire issue. the tv should come on when you resolve the blink codes or replace the fualty board or boards

Why does my panasonic tc p50st30 tv menu not work, tv will turn on but can not shut it off unless I unplug tv.


I would believe this to be a problem with the lvds cable that goes from your logic board to the main board. If your tv does not have a logic board, then it would have to be incorporated into the main board. A lot of times the connection gets loose on the main to logic board. If you reseat it, it may fix itself. If nothing else, you can pick up a logic board on ebay for around 25 dollars with shipping. It is usually very easy to replace. Most of the time, it's hidden behind the A board known as the Main board. It would probably take less than an hour to put in for someone not familar with the internals of a tv. Just MAKE SURE the tv is NOT plugged into the AC line.

My Panasonic TCP42GT25 turned off by itself and won't turn back on. The power source light is blinking 4 times and then pauses. any ideas on how to fix this? thanks.


Try disconnecting all of your HDMI cables and plugging the power cord of the TV into another wall outlet. If this resolves the issue, you may have had a small power surge from either your wall outlet or one of your source devices. It is recommended to connect your TV to a surge protector if you haven't done so already.

Panasonic TC-P42X1 acts like it is turning on, the screen turns black, then the tv shuts itself off and back on again.


Rule out any loose contacts in power outlet, RC Jack, cables and connectors. The problem described by you calls for opening the back cover and further investigation, which should only be done by a qualified service technician.

Likely a bad power supply in the set--only boards are sold so voltage into the supply and out needs to be the first thing that is checked.

Tv turns on for two seconds, shuts off, begins binking.


The problem is most likely a power supply related problem.
The TV is in protection mode right now. It's keeping the other parts inside the TV from being damaged by automatically turning itself OFF. The 9 blinks should be an error code for the problem with the power supply. I don't have the Service Manual for your TV model number to tell you what the code means and which part to replace. Every brand of TVs have a different meanings of the code.
If you have electronic experience, you can find a factory repair manual over the internet. Normally, it's called a Service Manual. It costs about less than $20.
