Why tv shuts off by itself?


Dear User,
People who have faced such problems have tried sticking th epower plug (Going into the TV) a little harder and the thing never went off again.

If this is not the case, then it could be the cat5 network cable. Try keeping it out and observe.
Let us know further
Regards,
Sid

Just bought panasonic th-42x20k, when turn on hear a clicking sound and then turn off, red light under screen flashing 7 times


Red light flashing indicates that "SC voltage is floating". I'd recommend replacing the SC, SD and SU boards. Also know as the Y sustain (SC), Upper and lower buffer boards (SD, SU).
I suggest you contact your local Panasonic Service Agent as parts are only available from Panasonic and are quite expensive.

I have a Panasonic TH-42PX600U that will not turn on


Normally the event that you saw is the power supply. Sometimes it can be a failure on one of the boards that caused the power supply to go in to protect, or be damaged.

You must consider that after about 40,000 to 50,000 hours most electronic devices reach their expected life. There is something called MTBF (mean time between failure). This spec for consumer products is evaluated at normal room temperature of about 72F. A warmer operating environment will reduce the expected MTBF.

As you stated your set is about 2.5 years old. This is before the average MTBF period. Your set must have maybe 25,000 hours at most. I would expect to have a few years more with it.

From my experience when a TV, or appliance, or moist any electronic device has about 5 years of age it should be at its end of life period. At this age of a device investing money to service it has risk something else can fail.

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

Picture and Sound flash from 'on' to a black screen


Hi, The problem lies within the unit. You have a hardware failure within the board. The power supply board needs to be repaired or replaced. If you are a handy person, you can easily swap the power supply board.. If not, bring it you to local reapir shop, they will find the parts and replace it for you. I wish I had a better solution like an easy fix for you. Sorry, but on hardware failure, there is no easy fix. Thanks, Mike
