Master thread for Panasonic plasma not turning on - Page 5

Hello again, I have (reasonably) good news. It's been determined that I have a bad power supply board and it looks like a new one is only around $250ish. One question I had was that my distributor needs the TNP # for the board and I'm not 100% sure (only about 98%) that I'm looking at the correct board. The one I'm looking at in the TV is nearest the plug and power relay on the back and it has an array of large 15w resistors and what looks like some large, heat-sinked transistors (it looks exactly like the board board in the next post down and in fact the number on the lower left corner of that board matches the number on my board). Sorry for no direct link but I can't until I hit a whopping 3 posts .

My question is, does anyone know the TNP # for the power supply board on a 58PX60U (which is shown as A3840 for the picture below)? Thanks again.

Here is the picture of the power supply board mentioned above ^

That is not a power supply board, it is an SC (scan) board.
The SC may be your problem anyway, how did you "determine" that the power supply was bad ?

TW

The P Board for model TH-50PX60U is part # ETXMM610MEF
This board does not have a TNP #

TNP # are Plasma factory board numbers which may or may not be the actual part number used for ordering.

Late model Plasma power supplies have ETX numbers, probablt meaning they are OEM'd from a sub-contractor.

TW

Thank you for the info, TW. The conclusion that the power supply was bad was made by a Panasonic tech via telephone (thus the reason I am posting to get more info). One day the TV simply wouldn't turn on and there were no display issues prior to this problem. There is currently no power LED showing and none of the reset steps that Panasonic suggested had any results. On a side note, in looking around near the plug receptacle, I noticed what appeared to be a large relay/solenoid on the receiving end of the power cord. If that particular item failed, then I would be getting the same results as I'm currently seeing, or would there at least be a power LED showing?

Also, I found what I believe is the correct P board for my set (58PX60U), model # ETXMM611MEH. Does this sound like the correct part number? Thanks for any help.

The relays do not usually fail.

The part # I had listed (610MEF) is from the TH-50PX60U Service Manual.
I cannot confirm that 611MEH is a substitute. It may be from an entirely different model. I would not use it unless confirmed by an authorized parts dealer as a sub.

TW

According to a Panasonic TH-58PX60U parts list, the ETXMM611MEH is the correct part number.

Ah HAH ! yes, that is correct. I was quoting a 50 inch, not the 58 inch that you have. Must be a little to much Saki when I read the original post.

Hi all,
I have the th42px6u. It is getting the 7 blinks. I read through this entire post and got a little bit of conflicting info. Obviously by the model this tv is not in warrantee and I need to fix it myself. I have fixed tvs before and also my job is fixing computers so I am comfortable with electronics. I read in the first part of the thread that 7 blinks = power supply board but then later read that it was the scan board. Are these one in the same? Is the scan board the one that the cord from the wall actually connects to? With a computer background I would automatically call that the power supply board but maybe in tv board terms it is more precisely called the scan board. If they are not one in the same then can any owners that had 7 blink problem repaired in or out of warranty confirm which board actually fixed the problem for them? I have access to the parts I need I just dont know which one to get. Any help would be awesome. It was given to me broken so if I get it fixed then FREE!!! Thanks.

7 blinks for this model is the SU, SD, SC, or SS boards.

Below are part #s for each board, either # will work as they sub to each other.

SU
TXNSU1BJTUJ
TXNSU1BJTUE
SD
TXNSD1BJTUJ
TXNSD1BJTUE
SC
TXNSC1BJTUJ

SS

Yeah, they're going to ship me a return label, then I've got to get DHL to pick it up and send it back, then they'll inspect it and send out a new one.

Hopefully the second one doesn't get dinged up as well...

Well that sucks that they use the slowest of the three options, but at least you'll end up getting a new TV in a few weeks so that's good. This time though, open the box while the driver is there and give the TV a good once-over, and also when you sign the bill of lading, quickly write "Subject to Inspection for Hidden Damage" right on the bill before the driver can stop you.

I have the 7 blinks. I did the test by unplugging the SU then SD. When removing the SD, the tv turns on and I get the top half. So I bought an SD to replace. It did the same thing. So I bought an SC board and replaced it too. Same thing. Could it be my replacement SD board was bad as well??? What else could be wrong. Please someone help! I've been without my plasma for 2 months now!
TH-50px60u
TNPA 3827
TNPA 3832
ps. I made sure that the ribbons were fully/properly connected when changing the SD boards

I have recently had the same problem with my Panasonic Viega Plasma Model TH37PE30B. It's stuck on Standby and I have sent it away for repair to a main authorised service centre. They report that it's the "P" Board thats faulty and needs replacing. Unfortunately you can no longer get a "P" Board TNPA 3336 from Panasonic. That's fantastic after only 3.5 years after paying over £2,000. Does anyone know where I maybe able to get a TNPA 3336 "P" Board?? Any help really appreciated as I can not afford another one.

Hi all!

I purchased a Panny TH-42PV70H 20 months ago in Singapore where I was based before. I shipped the set and have been using it for 8 weeks or so.

The Panny was connected to a voltage regulator that blew its fuse. A lapse of judgement, but I plugged the set to a power strip.

Then it made the red blinks and turned off.

I unplugged the set and plugged it again....the green light would blink for at least 4 times (not an accurate count), and I will see perfect picture and sound for a second or so. Then the screen would go blank and would do the series of red blinks until it ends. When you press the remote, the TV signifies detection by lighting the green LED, but that is about it.

I have been diligently reading the threads and while my query re: blinking has been answered (it is a service code), I did not see anyone talk about seeing a perfect screen + sound when they replug the set.

I hope that is a sign that it is just a simple trip that just needs time to reset. Any thoughts would be appreciated since the Panny technician here is already hinting a power board change (he does not even entertain the IC replacement that has been successful with many of our friends).

Could it also be just a case of a burnt fuse? the Mains of Pannys from Singapore have built-in fuses. I checked it out and it has burn edges. I cant see the filament because it is not the glass-type.

Potential damage for board replacement is 450 USD and 50 USD labor.

Cheers and hope you guys can help!

Just something to add....I checked how many red blinks and it was eleven (I was counting the light turn off as 1 blink).

I guess it is a FAN SOS PB board issue. Does this translate to a complete board replacement or just an IC?

Cheers!

Hmmm...problem is it takes a while to get the TV out of the packaging since it's double-boxed. I suppose I'll tell him what happened last time and hopefully he'll sympathize.

What does writing "Subject to Inspection for Hidden Damage" on the bill accomplish?

Thanks for all the input, Randy.

I recently set up a 42PX80U for my brother in law. t takes literally about 15 seconds to unsnap and remove the four plastic handles and lift the upper half of the box off, exposing the whole upper 2/3rds of the TV. If no damage is visible at this point, it takes another 10 seconds to lift the TV from the box, whereupon you can thoroughly inspect it for damage. If the TV looks perfect then you can send the driver on his way. If not, he can toss it back onto his truck as you write "REFUSED - TV WAS DESTROYED DURING SHIPPING" on the bill of lading.


Doing this has been instrumental in my company getting fully re-imbursed for electrical metering equipment or lighting products that were later found to be damaged after the driver left. Sometimes the very stiffly sprung bobtail truck can take a nasty bounce over a dip or speedbump or railroad tracks and the pallets get bounced, damaging the contents of the box. We've received $20,000 electrical metering modules that looked ok when we took them off the truck, but further inspection revealed that somewhere along the trip it had been transported lying on it's side and all the internal bussing was damaged or fractured because it is not properly supported unless it's shipped standing up during shipping. Light fixtures getting body-slammed on the back of a flatbed truck is another problem we often have and the damage isn't found until the fixtures are taken out of their boxes. Same goes for a pallet of flourescent lamps.

The same thing can happen with a plasma TV - the box can look perfect but even the best packing can't prevent the screen or bezel from getting cracked when the box bounces a foot into the air and comes slamming down onto the truck's floor. I used to drive a bobtail truck when i first started in my business and i've seen what damage can be caused by getting the back tires of the truck airborn over a dip or speedbump that i didn't have time to slow down for

Hi guys. I have the TH-42PZ80U 42" model and the tv crapped after an hour of use. I had just gotten it from circuit city and after watching tv for an hour, it made a loud popping noise and then the red light blinks 7 times.

The build date says August 2008 so it's one the latest ones. I'm going to go exchange it and get some kind of extended warranty.

Well my TH42PZ77U lost the power supply last week. Tech said that was the problem (number of blinks and would not turn on). This is the third service in two months so he said Panasonic would likely want to replace the set (9 months old). He called asked for a copy of the bill and sent it to Panasonic. Their reply was that they want to give me my money back , so I am waiting for a check. I was initially concerned because I did only paid $899 last December for the set (after the BestBuy promotion), but I was able to find a cost-effective TH42PZ80U at Circuit City this week. Good to know I will not spend much extra for a new set.

They're refunding your money because they don't have any more 42PZ77Us to give you. Whatever current model you get will not have that LCD-like Anti-Glare screen that the PZ77U had, so if you want or need that AG screen then you might want to insist that they fix the TV instead of buying you out.

But instead of the TH42PZ80U at CC, you might want to consider the Costco version (TH-C42FD18 which is internally identical to the PZ80U) instead since they add a year to the factory warranty, and they have the 90 day return policy compared to CC's 30 day policy. I was in Costco last weekend and i could not believe how low the price was on this 1080p set.

Thanks for the advice. I'll have a look at the Costco model this weekend.

Hi - if you still need the TNPA3336 board I've got one for sale, I was just going to list it on ebay but I'll keep it back till I hear from you - can you let me know if you don't want it otherwise make me an offer (bearing in mind postage cost approx £10.00 it is quite heavy) I could do it through ebay / paypal for security & peace of mind. claire

this is my first post here. Like many of you, Im glad I found this thread. I have a Panasonic TH-42PA20 it was manufactured in august 2003 and I purchased it fall 2003. The tv shuts itself off (this occurs most likely when I change channels or when a flash occurs in a scene) has one long red light followed by 6 flashes. Should I repair it? I hear that it could cost me well over 500$. I'm willing to spend the money but only if panny guarantees the work.

See this post and then read the rest of the thread.....

Thanx a million techniwizard. I appreciate your help.

I'll update you on the repair.

Just following up on my own situation with a dead Panasonic TH-42PZ77U with the 7-blink problem.

I called TV Repair AGAIN (the "only" warranty service shop on this island), and had this exchange,

Me: Hey Mark. Is my TV repaired yet?
TV Repair: Nope! But we're making progress!
Me: What does that mean?
TV Repair: Panasonic is starting to pay their bills.
Me: Oh. OK. So, where are we with my TV? Have you ordered the parts and just waiting for the parts?
TV Repair: No. I'm not doing any work on Panasonic TV's until Panasonic pays their bills.
Me: Oh. So the parts haven't been ordered, and you'll order them and start work on my TV after Panasonic pays their bills?
TV Repair: Yep. I'm not working on anyone's TV until Panasonic pays me what they owe. But we're making progress! The guy I spoke with last week at Panasonic seems to really understand.

WTF?!?!?!? He hasn't even ordered the part, and it's been sitting in his house/repairshop for 2 months?! Meanwhile, the warranty clock is ticking. I don't see how him not getting paid by Panasonic is my problem. That's a problem he has with Panasonic.

Anyway, I was told that Hatada's TV in Hilo (2 hours away) is no longer in business to do warranty repairs. I decided to call them to find out. Yep, they're still in biz, and yep, they still do warranty service work on Panasonics. I told him what I had. He said get the TV back from the other guy and bring it by next week but call ahead, because he likes to go fishing alot. In fact, he's closing his shop tomorrow because he's going fishing.

I figure I've got nothing to lose. Can't be any worse that what I'm dealing with now. Of course, I'll end up blowing about $100 in gas driving my truck 200+ miles, 2x times.

Such is life in the outer-islands of Hawaii.

Hmmmm, sorry about your situation.
FWIW, policy is usually to extend the warranty the same amount of time that it is in for service so hang on to any documentation showing how long you have been without your unit.

Well, what about giving it up as "stolen" or "missing, but you know who has it and won't give it back" ?

Here's an update on my Panasonic TH-50PX80U with a 10 blink power problem (associated with my HTPC with an NVIDIA 8500GT with HDMI output to the TV). Panasonic sent me (free) an "HDMI extender" (it was from monoprice). It took about two weeks to get it, but it did come, as promised. Basically, it's a coupler for two HDMI cables which "equalizes" the signal from the video source (in this case, the HTPC), which prevents the 10 blink problem. I can confirm that this fixes the HTPC 10 blink powrer problem. This "HDMI extender" is available for about $20 from monoprice.com, though panasonic sent it to me for free. Also, as I noted before, my 4 way HDMI switch (also from monoprice) fixes this problem, as well. Here is a link to the HDMI extender on monoprice. http://www.monoprice.com/products/pr...t=1#largeimage
