Panasonic model #TH-50PX75U wont turn on, it powers up but the led light blinks seven times

These blinks (flashes) are fault indication. By the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit stage inside the TV. Count the blinks occur at one time switch ON, carefully. Do it once again, and make sure about the number of blinks. If the flashes are continious, non-stop, the main system control IC should be suspected. If you wish to get more details, check the site linked here. It has blinking codes detail to many brand TVs.

That is a power suuply problem,i have the same problem i looking for a solution to fix my or i gonna buy a new one,also new onw is spensive on ebay some people offer the repair service good look

Unplug the power cord. Press and hold the power button for 30 seconds, repeat. Plug it back in and try to turn it on.
If this doesn't work, it would be time to call in a repair tech. Is the TV still under warranty? Extended warranty?

dear user,

your tv supply capacitors are weak kindly change it if you can

The tv power supply board is the causes and the problems.That the board,where the power a/c cord plug into it.Try website like Ebay.com to buy a refurbish power supply board for the replacement.

I would suspect faulty capacitors in your power supply, Take the back of and look on the power supply board for capacitors that have domed shaped tops, they may also have a brown liquid like substance leaking from them.

Replace these and this should cure your problem if it is capacitor related.

I have a Panasonic Plasma Tv, Model #TH-50PX75U and it will not power up. What can I do to fix this problem?

power supply fault

If you have 10 blinking red lights it is a problem with the DG board on the inside....replace this board and It will take care of any possible 10 blink issues.....

Caution: If you replace this board chances are it may happen again....go on ebay and get one for $25 to $80 and put it in yourself.....This is a known issue that Panasonic denies....

retail price is about $380 to $480 for a new one......dont do it!

there is an input button. Press this button untill you reach the input that you plugged into.
