Panasonic Viera: The television will not turn on, power light blinks 10 times (red)

Sat, 02 Aug 2025 18:56:57 -0700

From my preliminary research, I think it has to do with a fuse and the internal power supply. Anyone have any instructions on how to replace it or what parts I need to buy?

I also found this guide:

Is it worth pursuing individually, or should I just take it to a repair shop?

Panasonic Viera: Panasonic TX-P50G10B - Not turning on - Red Light 3 Blink Error

Tue, 01 Nov 2022 05:50:51 -0700

Hi,

I've got a Panasonic TX-P50G10B Plasma which blinks red 3 times when turning on. I tried changing the power board however that didn't help, and upon further research I found the manual for the TV which said the A (AV) board is the suspect. I changed it with a board from eBay however the problem persisted. I assumed it was a bad board so returned it and bought a new one.

I fitted the new one today and the result is different;

Before: Plug power in, press power button, TV tries to boot up (green for a few seconds) then 3 red blinks.
Now: Plug power in, press power button, TV is in standby (solid red). Pressing On with remote turns the light to flashing green then green, no picture (or noise of TV turning on). Holding a TV Vol button whilst pressing On button tries to boot up TV and then the 3 red lights blink again.

So I’ve changed the suspect board twice now, and still have a 3 light error, with slightly different results.

Could it be?

1) Something shorting the board somewhere else in the TV which has broken the 2 new boards as I put them in.

2) Both boards have been bad.

3) TVs just busted.

Thanks for any help.

The model number is TX-47AS740B i have only had the Tv for about a year or so. Is there any way you can help? Thank you.

Panasonic Viera: Dark marks showing on the LED screen

Mon, 20 Aug 2018 04:42:06 -0700

I’ve noticed dark patches appearing on the screen, mainly around the border. They stick out especially if there is a lighter colour on display. They’re there all the time and now that I can see them I can’t focus on anything else. Please help.

Thanks for getting back to me... I did enter all the details including the model number etc when I submitted my question. Its the TX-55DX650B.

Panasonic Viera: Panasonic Viera TC-P50V10 doesn't turn on, blinks.

Sun, 22 Jan 2017 21:15:49 -0700

My TC-P50V10 won't turn on anymore.

When I plug it in, the red light turns on, and 2 seconds later, it turns off.

It then starts blinking. I started counting the number of blinks, but once it got past 100, I stopped counting...

A few days ago, when this issue started happening, I was able to reset the tv by holding the power button for 60 seconds. That process worked a few times: I was able to turn the TV on. As days passed, that process became more and more unreliable. Now, nothing I try works. I've cleaned the fans too.

I've included pictures, please take a look. I added a grid to the pics hoping it would help you communicate which components I should test:

Hi @oldturkey03, I tested all the pins, and got these numbers:

Panasonic Viera: Panasonic Smart Viera TV no red standby light won’t switc

Fri, 18 Aug 2023 16:15:04 -0700

My electricity popped on main switchboard & TV went off, there’s no red light showing for standby. This isn’t the 1st time this has happened as TV has long spells of not being used. In the past your suggestions have worked perfectly but unfortunately not on this occasion!

Have retried your advise ie unplugging / holding standby button on back of tv for 60 secs / Holding both volume & standby button on back of tv for 60 secs / Checked fuse etc to no avail. Was hoping to have a lazy Sunday in front of TV but don’t think that’s gonna happen!! HELP

Thank you so much….
