Panasonic th-50pz80 10 flashing blinking red lights

I just purchased the tv, cables hooked to tv, everything goes throw the rcv'er hdmi out to the tv. 
Problem is when I turn on the tv with HDMI cable plugged into hdmi 1 or 2 I get blink flashes of 10 times then blank and restarts again but NO power on.
At first I thought it might be the cable but then I plug into HDMI 3 upfront everything works great. problem is I want all the cables in back of tv... 
What can cause this problem? The rcv'er is a onkyo

    folks, figured it out based on another posting with the onkyo rcv'er....

    Here is the scoop - if you rcv 10 flashing light at start up, you need to turn off the onkyo amp. TV must come on first then the amp can come on. Not sure why this is an issue but at least there is a work around... called CS and they stated that the 10 flashing lights is HDMI related...

The way to solve the problem with the TH-50PZ80U blinking light problem is to not buy Panasonic Products. I have had my TV about 21 months and it has started with the blinking light problem, just out of warranty. Panasonic is aware of this problem and refuses to do recall or fix the tv unless you are within the warranty or have bought the extended warranty. Legally they are within their rights, but I am also within my rights to air my complaint and inform others of this below par product. Who wants a TV that they have to unplug for a while and pug it in again for it to work. I want to push the power button and it come's on. I will never purchase another PANASONIC PRODUCT.

    I also bought the same model and my panel has failed after only 2960 hours of the 100,000 hours it was supposed to get, so do the math I got 2.9% of what I should have got. It is also out of warranty, I did not recognize the problem until it was too late. This TV was in the basement rec room and was only watched on the weekends so it was not on enough for the failure to happen sooner. This is what to watch for it started out as very faint static in only one line on vertical resolution and as time went on the static become a little more visible and also it was only in certain color spectrum's. Everybody in my household thought it was the networks because like I said when you changed channels it would not be there because it was only certain colors were the problem. The problem over time gets worse, the line gets longer and it slower at color changing. That is when I called Panasonic, at first they assured me it could be fixed and to bring it in to the closest repair shop which does all the warranty work for Panasonic. I brought in to the shop and I described to one of the techs at the shop what the problem was and he said it sounds like the panel is shot and that cannot be repaired or the cost of the repair would exceed the cost of a new TV. The shop faxed Panasonic a copy of the diagnosis and faxed them a copy of the original receipt which by the way if I did not have they would have blown me off right away but I have everything. Panasonic called me a few days later and offered me the opportunity to buy direct from them another TV equivalent to this one @ a $500 savings from retail. This is **** I paid $2768 after tax for the TV just over 2 years ago, I was insulted. Let's figure I could get the TV $200-$300 hundred dollars cheaper than suggested retail anyway plus I spent $100 to the techs to tell me my other TV is JUNK. Quality products

    Here is a blurb from the Panasonic Website

    We built our reputation by making products that last. Our dedication to quality, innovation and value reveals itself in everything we make. If you’ve got an old boom box in the basement that just won’t quit playing, chances are it’s a Panasonic!

We endeavor to become a "Customer Value Creation Company" that provides safety, security, comfort and convenience in line with our visions of contributing to a ubiquitous networking society and co-existing with the global environment.

    I don't think so

I had the same issue when I used one of the rear HDMI ports to show a PC display. Apparently there is a software difference between the rear and side/front ports. Inputting the PC through the side HDMI port has solved the problem for me (so far!)

TH-42PX60U red light blinks 10 times wont come on

On a Panasonic TV the 10-blink error code can sometimes be caused by low voltage running through an HDMI cable, particularly from a Media PC or some video game consoles. Try disconnecting any HDMI cables and unplugging the Television for 30 seconds, then power it on without the cables attached.

If this works, connect the cables to the front panel (usually HDMI-3) which uses a different controller board.

I just bought a Panasonic TH-42PZ800U and had the same problem. 10 blinks and the TV would not start. Then after some trial and error I solved the problem!

Here is my (apparent) observation and solution:
I had only one input into the TV, which was my HTPC connected via a DVI-to-HDMI cable plugged into the Panny's HDMI 1 slot. *IF* the HTPC was already on, then the Panny would have the blink of death. *BUT* if the HTPC was off, the Panny booted fine (assuming I cleared the blink of death first by powering off the HTPC, unplugging the TV, and replugging the TV back in with the HTPC still off).

My solution was to move the HDMI cable from slot 1 to slot 3. After making this one change, everything worked as it should. No more 10 blinks of death. I could even leave the HTPC on and turn on the TV last, and it still worked. Tried this 10 times, worked 10 times.

I don't know if this will solve other people's problems, but I hope it at least provides some clues. I wonder if this is a fundamental circuit design flaw on the part of Panasonic, rather than a "bad batch of parts" problem.

Power light blinks 10 times

You have the same problem i have. My Tv just did the same thing 3 nights ago. I unplugged the set, and let it sit ofr about 6 hours, and then tried it again. It turned on and played, but repeated the problem after about 20 or 30 minutes. So far all my research has led me to believe that its a power supply issue. Problem is, there are 5 boards in the tv with seperate pwer supplies, and the 10 red flashes indicate that its all of them. :-(. Im shopping for a new TV, and It wont be a panasonic this time.

Red light flashes 10 times - Panasonic TH-42PX6U

hey there! i finally figured it out!! If you have a computer hooked up with the HDMI cable in the back of the TV and the computer is either on screen saver mood or sleep mood then it is trying to make the television go to sleep aswell. So the only way you can have a computer hooked up to the TV is if you use the front HDMI hook up. pretty weird but thats what was wrong with mine. Hopefully that was the problem :):)
