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

I have a Pansasonic HD Plasma Model TH-42PZ77U manufactured on September 2007. Everything was fine until today, it won't turn on at all, the power button blinks 7 times, stops for a little bit and blinks again 7 times as well. I tried moving the HDMI cable in the back from slot 1 where it was to slot 2, but nothing happens. Please advise.

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

Marine on a mission here! To help every one that takes the time to post their problem. Times are tuff. PPL need to put food on their tables and not worry about calling in a tv repair man and spend hundreds. Took me a year to get the fix. Fixed 2 50" plasmas for 80 cents. After being told it would be better to replace than repair. BS! I held out glad I did. This is free advise, it will cost your your time and some pocket change.

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.

Panasonic Model TH-42PZ77U doesn't turn on


I contacted Panasonic and it seems that they will take care of the problem even though the TV is out of the 1 year warranty. They are aware that this is a manufacturing defect, apparently. I'll follow up later to let you know how it turns out.
