Is the newer V10 model prone to this problem with the tv not turning on?
post #393 of 1978
Add me to the list of 10 blinking lights with HTPC connected.

Thanks to svkowalski i was able to figure out the issue. I called Panasonic and the girl knew exactly what my problem was. They are sending me out an HDMI extender kit. If all works well then i am happy with Panny again.

Aside from this issue i absolutely love this TV.

Which problem? If it's the 10 blink HTPC on the rear HDMI ports problem, then no.

If it's one of the other problem where the TV doesn't turn on, then it only happens if your TV is defective, and that could happen on any brand and model

Cool. I was mainly concerned about whether the original post of this thread was related to older model panasonics, or if could potentially happen to the V10. I have a V10, and I know a few people with older panasonic plasmas, but never heard of anyone peronsally having an issue with their tv not turning on.

Got the TV back.
with fw update as well.
Total Cost $254.. and change.
I did inquire about the fw update and have been told its neccessary to keep tv from breaking.

10 blinking lights last night with new Apple Mac Mini (mini DP -> DVI -> HDMI).

After a brief stroke (it's only like 8 months old), I found the cause (thanks AVS) and reset the TV.

Tried to call Panasonic (CANADA) and was told I should go out and buy a Monster Cable HDMI amplifier.

Needless to say, I'll be sticking with my current solution (tell Logitech Harmony 550 to turn MacMini to sleep when TV is turned off, power MacMini on last when turned on) or possibly purchasing from monoprice if things become annoying.

Any Canadians having luck getting Panasonic to ship out the piece?

Hi,

Having read through this entire thread I tried the suggested troubleshooting steps for my TH-50PHD7UY:

1) Disconnected SD board
2) Disconnected SU board
3) Disconnected both SD and SU board

In all three cases, the TV momentarily turns on and the fans spins for a moment. I believe the backlight also comes on for a moment. After about 1 second, a buzz can be heard, I believe from the SC board and the TV goes back to the 7 blinks (as counted when they go off).

Am I right to assume that the SC board is the problem? Can I dertermine that without buying the replacement board first?

I wish my first post was more positive! Thanks to this forum for getting me this far. Any help is appreciated!

My 22 Month old TH-42PZ700U failed to turn on last Tuesday with 7 blinks. Called Panasonic and faxed original receipts. Heard back on Thursday and was told that local service center will get in touch for fixing a appointment for a free evaluation.
Heard back on Friday and have an appointment for tomorrow. Service rep said that if the problem was the SC board Panasonic will cover it. Anything else and we would have to pay. In the meantime confirmed with Amex that they would cover any repair costs.

Keeping fingers crossed.

Mine has been in the shop since September 1. They have been trying various boards and have not found the one that works to fix the problem with the set not turning on yet. I had 10 blinking lights. The last I heard they think it may be the power supply.

Talked with Panasonic and ask if they would cover the cost of repair if the set is defective. I was told that they would be fair.

Mine is the Panasonic TH-42PZ77U purchased 11/16/07. Out of warranty.

i am currently in the process of getting the panasonic 42 plasma blinking light problem fixed. my tv is 1 yr and 11 months old. i called the panasonic support number and faxed the paper work to them. they approved my tv to be repaired under warranty by getting a manager override. the tech called today and mentioned panasonic extended the warranty another year due to this issue. i will see what happens when the tech comes weds to repair. he also said he has not had to fix it twice, due to the the new boards come with new firmware loaded.

The tech came a while back and the TV is fixed. Less than a week since the problem showed up, not bad. Changed the SC board and upgraded the FW from 47.06 to 47.09.

The whole thing did not take more than 30 minutes.

I am off watch a movie to celebrate.

Could be a fan rotation error (6 OFF blinks) check the fans as they ramp up to speed and blow out the dust bunnies and hairs from the bearing area. Fans will need replacing anyway if this works for a few minutes.

Thanks Techniwizard! I'll give that a try and post back tonight with results.

Panasonic Canada was not willing to help out with this unit. They offered that I bring the unit in, and have it checked for $150. SC board was quoted at $500+. Hardly seems worth it for a four year old TV. Panasonic stated that this is not a design issue (if it is the SC board), and pointed out that they don't give lifetime warranties. Oh well, it was worth a phone call.
post #406 of 1978
As most of us find out that even if you have a 4 year total extended warranty(1+3 year)
After that expires if the tv goes for a pooper what do you do then?

Fix the tv at the prevailing rates and cost?
That will ramp up quick.
Buy another tv and an extended warranty again?

Probably the best course of action, unless the repair is small dollar but thats hard to know going in

Seems like a lot of potential tv's and dollars chasing them for the privilidge of turning on the idiot box.

Years ago you had a crt tv for 15 years and you were surprised if it broke once.
In fact I can state I never had a tv break that I have owned till this debacle.
Thats a lot of tv's to for a zoomer!!
Including 3 portable battery models, one a VERY high quality Sony miniture colour getting banged around, thou they were all crt.
Seems they, crt style have all but disappeared now.

If the current tv market with its associated service issues is progress I'd hate to see what they call regression
Mind you it depends if you are one of the 2-4 % so they claim, that has issues...but if you are....it does matter to you!!
If you have no trouble you can gloat, good for you...for the time being...till it blinks on ya!
post #407 of 1978
The repair evaluation states that the following boards need to be replaced.

P, DG and H.

I had 10 blinking red lights.

I faxed my receipt in dated 11-16-07.

Waiting to hear back from Panasonic.

TV model is TH-42PZ77U.
post #408 of 1978
Tried following up with clearing out the fans - definitely not the issue. Confirmed once more that it is definitely 7 blinks.

Is it possible to test if the SC board fix will work before actually buying the board? My board is also hard to find TNPA3215 (or TNPA3215AB if you include the stamped letters after the silkscreen).

Any help would be appreicated!
post #409 of 1978
I had 10 blinking lights and have now been told that 3 boards need to be replaced. Waiting to hear back from Panasonic to see if they will help with cost of repairs. I am out of warranty.

Repair estimate is $687.00.

This is a 42" Plasma. Worth repairing if it is my $$???????
post #410 of 1978
If its going to cost that much just buy a new tv and put it on an extended plan.
Unless they will help with repair.

Or save big dollars. get a used crt and camp out with that.
Its only the idiot box.
post #411 of 1978
Folks,
My th42px60u doesn't do anything all of a sudden. Its like its not even plugged in (which it is). The unit is about 2 years old and had no problems until now. When I press the on/off button on the front panel, i get nothing at all. no lights, no nothing. Can anyone direct me?

post #412 of 1978
Folks,
my Panasonic TH-42PX60U blew the two main power fuses. After replacing them, I get 10 blinks. I have nothing connected to the unit. The confusing thing for me is that this thread is stating that its definitely a video board. Others are stating a power supply problem, others are saying 10 blinks is a generic code with many possibilities, some are associating the code with being connected to certain ports, etc. I need someone to help that know what they are doing - if possible.

If its a video board, please tell me how to identify that board and where to get a replacement.
Thanks for the help.

Codes are different for every model year and sometimes differ between models. And the code chart is only a guide, it is not a be all end all. There is no way to determine exact failure cause sight unseen. This is why electronic servicing is relatively expensive.

The correct chart for your model is attached. 10 blinks indicates a possible bad PA/H board assembly. Both should be changed at the same time.

BTW, starting a new thread for each new post on your issue is not recommended. Try to keep new posts within the same thread to avoid confusion.

Thanks again TechniWizard for your help - as I mentioned I tried the fans but it did not help. Do you (or anyone else reading this thread) know if there is a substitute/equivalent board to the TNPA3215 (SC board) for the TH-50PHD7UY? Also, can you tell if the SC board will fix the issue before buying it?

Thanks again for any help you can provide.
post #415 of 1978
The correct order # from Panasonic parts is TXNSC20UPS.
The TNPA3215 is what is silk-screened on the board.

TH-50HW7UY was a similar consumer model at the time and uses the same boards.

Sadly, there is no easy way to check for certain if the board is bad before sinking money into it.

BTW, fans could be spinning but still give a rotation error.

Usually, you will get a pix for 1-2 seconds before a fan shutdown.
A bad SC (or SU/SD) never fires up long enough to give a pix.

About a month ago I bought the Model TC-50PS14, the 50" plasma from Panasonic at Costco as it currently goes for $999 after $200 rebate(purch. in late Aug 2009).
.
After my roomie played Oblivion all morning (3 hrs) on the 360, I watched football all day(6 hrs) via satellite in HD and the screen froze, turned all discolored and squigly for a second or two then went blank. I freaked the crap out for a bout 10 minutes, saw the power light blink (I did not count how many times) then calmly unplugged the tv from the surge protector and tried to power back on.....nothing...then I hit a bunch of pillows and the wall....a minute later I tried again......blinks of death......cried a little and repeated the power up.....SUCCESS!!! TV worked fine for the rest of Sunday night football and a little "light" pre-bed tv watching ( I have a problem...I know)
.
my question is, should I just go and try to get a new tv from costco, update the firm ware or what? It seems like if this happens once on a set, then it is destined to happen again. that is what I got from reading this thread anyway.
post #418 of 1978
I had the 10 blinking lights with a repair estimate of $600.00 plus. Panasonic has offered to pay for 1/2 of the price of the parts.

I told them I felt that Panasonic should pay for all the parts since these sets were not made to last. The repair estimate is to replace 3 boards.

They are going to see if they can locate some parts to reduce my bill. I am not sure what they means. They said if they could locate the parts that would reduce my bill $400.00.

They are suppose to call me back tomorrow and let me know.
post #419 of 1978
Bought a Panasonic TC-P50S1 3 months ago and it is dead already. Getting 8 blinks on the LED. I guess three months isn't bad ... POS
post #420 of 1978
I also am experiencing the blinking light issue. I purchased a TH 50PZ85U at Best Buy approx 1 1/2 years ago. Purchased the extended service warranty just in case, but read nothing but good reviews about this TV.

In late August, after a period of doing the 2 blink no power/unplug/then plug in agian to get it to turn on, it finally would not power up at all. Blinking 2 light issue.

Contacted Best Buy to set up a service appointment, which could not be scheduled for a week and a half. When Tech arrived, he diagnosed over the phone with a help desk, that the problem was the "A" board. When I asked what the "A" board was, he paused and gave me a vague answer that indicated to me he didn't really know. He placed the order for the replacement and set up a return visit, 9 days later (even though the part showed up at my house 3 days after his initial visit).

Well, today was the day to come and install the "A" board and get the TV back up and running. Guess what? The new part did not fix the problem, still 2 blinking light issue! After diagnosing over the phone with the help desk again, it was determined that the power supply is no good too. Another part put on order and another return visit scheduled in 8 days! I don't know what I'm more pissed about, the troubleshooting/repair philosophy of Best Buy, or the perceived poor quality of the Panasonic set.

Don't you think that with a problem that appears to be widespread, that Panasonic would have packaged "retrofit kits" which contain the neccessary parts to permanently fix a known problem? This all seems so hit and miss to me and my confidence that it will not occur again (once it ever gets fixed) is pretty low.
