There was a widespread problem with some Onkyo receivers where they were unable to send a certain signal that the TV required so this may be what you're experiencing. The problem was not with the Panasonic TVs - the problem was some sort of flaw in the Onkyo's firmware that rendered it incompatible with some Panasonic TVs, and i believe Onkyo provided a firmware update to correct the issue.

We need those exact model numbers to investigate further.

Have you at least tried temporarily connecting it to the TV's HDMI-3 input to see if you can get the signal? The HDMI-3 workaround was used on 2008 models when an HTPC with an incompatible video card was connected to one of the rear HDMI inputs. Again, this was not a fault of the TV, it was due to people using a non-standard source (HTPC) with an incompatible video card that did not provide the necessary signals to the TV in order to get a picture. Replacing the video card with a better one solved that problem.
The TV is a TH-50PZ85U and the receiver is a Onkyo RC-360.

Also, the issue arises if I have the receiver on first, and then turn on the TV. If I turn on the TV first, and then the receiver I have no issues. If I turn on the receiver, and then the TV, I get 10 flashing lights and I have to unplug the TV before trying again.

The PZ85U is one of the models that the Onkyo didn't play nice with. Have you tried connecting it to the side/front HDMI input to see if you can get a proper signal?

I seem to remember that Onkyo came out with a firmware update for their affected receivers to make them work properly with the Panasonic plasmas so you should definitely check into that with Onkyo or search some AV forums for this issue and how it was resolved.

Unhappy 7 blinks of death

here's something that i did not come across in reading about everyone's issues with the blinks of death....my panasonic started its death blinking on the SAME day that our cable provider (verizon) did their upgrade. This is WAAAAAY too much of a coincidence for me. The kids turned on the tv before school 1 morning and they called me because ''there's reading on the tv!'' when i entered the room i could see that their show was not there just a big gray screen informing you of the upgrade and then i needed to make some choices on the screen....then the kids were able to watch a show. a few minutes later the screen went black, 7 red blinks began and here we are days later. Never had a single issue in the 4-5 years owned this tv. its a great tv. cable guy was here and said not a cable issue, issue is with tv, even showed me on his phone how he googled it and found all kinds of stuff on 7 blinks of death.

So is it safe to say its an issue with the TV or is it the Onkyo's fault? I have tried two different receivers (both Onkyo) and they both have the same problem. Do you know what other Panasonics were affected?

Default 10 hours and my Panasonic 42 Plasma TC-P2s30 is Dead!

I just got this this morning from Best Buy. Set it up and it looked great, worked fine all day. Watching TV tonight and my daughter leaned on the remote and accidently turned the power off. Went to turn it back on and got the " blinking light of death " as another poster called it. Unplugged it, waited 5 minutes and plugged it back in and nothing but the blinking light ( 7 times by the way ). Called Panasonic and after waiting 15 minutes the CSR told me that the TV was broken and would need to be serviced! She said there was nothing she could do. I am dumbfounded. How can something this expensive be so fragile. I will never ever ever buy anything that says Panasonic on it for as long as I live. If you like disappointment and the exercise that goes along with picking up setting up, repacking and returning a tv then this is for you.
Beware ! Do your research on " shutdown mode " and blinking light for these TV's.

People, please don't buy into ignorance. Understand that every year the blink codes change and can mean different things. These codes are merely a diagnostic tool for servicers. This happens with all manufacturers. If it is within the stores return policy, that is your best choice for quick resolution.

My TH-42PZ700U died the other night(Halloween 2011), got 10 blinking lights. Tried letting it sit over night unplugged, disconnected all the inputs (2 HDMI, component, and regular rca), tried different outlets. Same results. I bought it back in late 11/07. The service manual for 10 lights on this model suggest it is an issue with the DG board(but some other manuals suggest several boards). When I plug in power I am pretty sure I hear 2 consecutive clicks, maybe 1.

Anyways, I emailed their concierge service and they said it was out of warranty and to call a service center. So I called the Panasonic Customer Service today, told them the same things, and they said it was out of warranty. I then explained that the TH-42PZ700U and TH-42PZ77u have had extended warranties an additional 2-3 years because the power supplies were defective. He said, yes this is true, but the 10 blinking lights error code suggests it is another issue, and not the power supply and that a Panasonic certified service center would have to evaluate it first, but it is most likely a different issue, and will not be covered.

On the phone I suggested that couldn't the faulty power supply issue cause other components to fail, he said possibly that I will need to pay a technician to diagnose it first.

I will probabaly call the service center just to see what they say. But I am inclined to call Panasonic back and ask them to repair it free of charge.

Anyways, I want to open up the tv, and see if there is anything I can do first. If I remove the DG Board (HDMI and RF tuner) and turn on the tv, will the tv power on if it really is just that board?

I don't really have much experience with this stuff, I have solder some things in the past, but long ago and very basic. And I don't have anything to tests voltages, or even know what I would need(multimeter?). Nor do I really have a space or time to really work on it. Should I just get a technician to just evaluate the tv, and tell me what boards are shot? From everything I read it seems it even takes technicians several attempts and replacing different boards to fix a plasma. If it is just a board or 2 that need replacing I feel I could manage that on my own. I have the service and repair manuals.

any help or suggestions for my next step is greatly appreciated. Thanks

Well, it doesn't take a good technician several boards to fix a set. The models you speak of are not covered under an extended warranty due to a power supply issue, it was for something else completely. If the call center rep told you anything different, he was wrong. That being said, if you were having the issue that it is covered for, panasonic would have paid for the evaluation. It would be an extensive troubleshooting procedure to figure out which board is faulty in your set, but I've seen it be as simple as a coin in the SD card reader causing a 10 Blink shutdown. There are a few ways to procede. Panasonic is just about one of the best companies around as far as customer service is concerned. They will usually cover a portion of the repair(this requires an evaluation). To make this smoother, I would recommend a panasonic authorized servicer. The call center can provide the closest one to you. Best of luck on what you choose to do.

If you want to attempt to repair it yourself, start a new thread and I can help you. I've helped several people on this forum fix their T.V.s

I am just going off peoples threads on different boards, about technicians bringing wrong boards and re-frying boards until they find the right one. I really have no personal experience with this.

And when talking to the customer service rep I was just repeating what I read in this thread, post #187, (about faulty power supply boards warranty extension) to the service rep, and he did say that info was correct. So take that as you will. I couldn't find where this info originated though.

I started a new thread with an update to me trying to fix it

My Panasonic TC-P42G25 just went out. A red light on the front of the TV blinks 4 times then a slight pause and 4 times again. The tech came out (thank God I got the extended warranty) to the house, but could not fix it and had to return to the shop because he did not have the tools to read what the blinking red light meant. So I guess it will be another day or so before they can return and or order the part. But from what I am seeing, this seems to be an ongoing issue. Wonder if I will ever get it fixed or have to fight with HHgregg to return it for an exchange.....
