Panasonic plasma power button problem

Problem getting power button to come on. Same with the remote. Have to play with it for a while to get it to come on. Once it is on it is fine, but you don't want to turn it off. Takes forever to get it to come on again.

    It is ONE Blink but I hadn't been able to find anything for just one blink. I had read about updating with the SD card but he had already taken the thing apart and that just seemed to simple. Thank you, Thank you, Thank you!!!

SOURCE: Panasonic 32 inch LCD TV will not turn on-red light flashing

The number of flashes is an error code. Count the number of flash. It looks like one of the boards in your set is failing intermittently. Panasonic codes for a guide as a starting point. Exact board STILL has to be verified;
One Blink: One blink of the power LED indicates a problem in the inverter circuit located on the LCD panel. The inverter board is not to be repaired in the field. Therefore a replacement is required.
Three Blinks: Three blinks of the power LED indicates an over-current or over-voltage condition in one of the DC supplies of the AP board. The AP board is repairable. Therefore the use of an ohmmeter and peak-hold-voltmeter is required to determine the cause of the shutdown. An over-voltage condition is definitely a defect of the AP board. An over-current condition may be due to a short circuit located in the AP board, A board, or the LCD panel.
Five, Seven, or Eight Blinks: The A board is responsible for five, seven or eight blinks of the power LED. The MAIN +3.3V, MAIN +5V, and MAIN +9V sources are all produced on the A board. The detection input pins of the MPU, IC1100, monitor for their presence.
Four or Six Blinks: The AP board is responsible for four or six blinks of the power LED. The DTV9V, and SUB_5V sources are produced on the AP board. The MPU IC1100 monitors for their presence when the unit is connected to AC Power. A short or open circuit on the A board may also be responsible for their absence.
Nine Blinks: Nine blinks of the power LED is due a short circuit in the audio output circuit (s) of the unit. The audio output circuit is located on the A board. Confirm the status of the speakers. If defective, perform a replacement. If ok, replace the A board.
Ten Blinks: Ten blinks of the power LED indicates a malfunction of IC4200, the frame converter. This IC resides on the A board. Therefore ten blinks of the power LED requires the replacement of the A board.

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

SOURCE: Panasonic Viera 46" plasma~no sound, no picture

I would use the warranty at Bestbuy at that point. Opening up the TV would most likely void the warranty.

SOURCE: Panasonic plasma 50PZ85 power led blink 10 times

Either a bad power supply or a bad processor board.
A Good Service Shop should know what the 10 blinks are indicating.
May be a repair cost between $200 and 400 dollars.
Be prepared -

Hi:
You will need to count the number of red led blinks on the power indicator, if it is at least 10 then replace the power supply it is faulty, In my years of servicing panasonic Plasma, power supply failure is about the most common failue in this class of television from this manufacture.
