Question about Panasonic Televison & Video

1 Answer

When I try to turn on my Panansonic TH-42PZ77U it blinks 13 times then pauses and continues to blink in intervals of 13. I called customer service and they gave me the area Service centers but since it is out of warranty I wanted to get a heads up on what the problem is and what the cost will be. Thanks.

    Had the same problem so applied some heat with a heat gun around the heat sink on the main board to try and reflow the solder and it fixed the problem for about a week retried the same fix with a spray on solder flux also lasted about a week

My panasonic is not coming on,the power button is just flashing red(TH-42px50u)


Count how many times it blinks. Sometimes the problem is coded in the amount of times it blinks. If you see a distiction between blinks, say like 13 then a pause then back to 13 more blinks, google solutions for a 13 blink standby for your tv and you might be able to find the soultion.

Panasonic th-42pz77u has no picture.power light (red) flashes 7 times


seven blinks on this model is the SC board. it will need a new SC board and the software update for the new board. usually only authorized servicers have the software need to do the upgrade. but if you were to contact panasonic then they might be able to have it fixed for you for free since this was a defect in manufacturing. of course this depends on how long you have had the tv.

TV power light blinks 7 times but it won't turn on


Most people call this "The blinking light of death".(part went bad)
Your TV when into protection mode to prevent further damage.
The repair shop may cost over $100 for someone just to look at it.
Or if you know someone with electronic repair knowledge, they have a service manual at nodevice.com
Most replacement parts you can get a shopjimmy.com ( go there to just to get an idea of what the parts costs).
Good Luck
