Panasonic TH-42PA20 shut down issue
While watching my Panny today, I heard a nasty whinning sound for about 5 seconds and then the Display powered off . It was a very high pitched sound followed by the power cutting off. I was unable to turn the power back on until I unplugged the display and waited a few minutes to power it back on. Since this occured this afternoon, it has happened three times since. ANy ideas what may be going on? Thank you.

Cabber,
As I mentioned in my PM, Panasonic is coming on Wednesday to repair the TV, replacing modules 5 and 7, which the tech said cost > $800 apiece. I spoke with a manager, who suggested they might replace the TV or refund me if the repair does not solve the problem, but that could only be authorized after at least one service attempt. Does anyone here know what modules 5 and/or 7 are on the 42PA20? Or have any other suggestions to press Panasonic for a satisfactory resolution? I certainly hope the repair solves the issue, as the PQ when the TV works is excellent, but I'm not too happy about having a 2-month-old TV that requires such a large repair.

Not yet, they postponed the service call until Friday. Will update then--if they don't postpone again.

Same problem here, what's the deal with this???

Sorry for not posting sooner. My TV was repaired in home by an authorized tech, then had the exact same problem the day after repair. It was then sent to the factory for service (Panasonic would not replace it) and is expected back today, a few weeks later. (I've now been without a functional TV for 6 weeks). I will report back to let you know if they successfully addressed the issue this time.
I was under the impression that this diode problem was well documented within Panasonic and replaceable on a house call basis. Hopefully this is still the case.

"Technically speaking, this is part of a protection circuit that shuts down the PDP if any of the working voltages dip below 75% of their nominal value.
This particular problem is due to the shutdown circuit being too anxious to do its job. It had to be mellowed a bit, made less sensitive, given an electronic traquilizer if you will.
All units since Sept 1 production have had the improved parts. More than 99% of the original parts stock were well within specification and will last as long if not longer than the new ones.
All service parts and boards have been changed to the newer stock.
To answer your question, the consumer group will probably send an authorized servicer with a replacement module if needed to perform the update on site. Broadcast units may be serviced at any of the regional centers and also at authorized Broadcast service centers now in some major cities nationwide. Check with your nearest region for locations."

this is really a troubling report

Mark,
Yes, this issue has been troubling--and incredibly frustrating, given that I've been without a working TV for 6 weeks on a unit that was 7 weeks old when this issue first occured. I tried everything I could, but they would not replace or refund the TV, even after the first repair didn't work. In my case, they did replace the entire module, but it didn't take. After having the unit on for 2-3 hours, it shut off again repeatedly. They said that sending the unit to the factory was the most expeditious and best way to resolve the issue, rather than keep sending people to my house. I was told by the tech that the entire process from pickup to return would take 5 days. Well, it's 2 1/2 weeks since they picked the unit up (3 1/2 weeks since they said it would have to be sent to the factory)...and the TV is scheduled for delivery to the local service center today. Hopefully they'll deliver it tonight, but when I called to give the tech a heads up that the unit was on its way he responded by hanging up on me. I'm crossing my fingers this fix took, otherwise I'll have to prepare for more (and I've already had my fair share of) headaches dealing with Panasonic.

Sorry to hear about your Panny woes...
Does anyone know if the 37inch version of this model is also afflicted with this problem?? If so, maybe I should be worried (the set I have has a July manufacture date).

I agree. Seems to me that in this particular case at least, Panasonic is going so far out of its way to not replace the unit that they've probably spent about the same amount of money.
I think at this stage I'd be escalating this as far up the chain as I could.

could you tell us the location of the service center that hung up on you?

Wow,
I hope I don't have to go through the same trouble as you. I would be extremely peeved if that was the rediculous service Panasonic gave me. I've had my TV for about 7 weeks, just like you (july/03 prod date) and just recently it started acting up. Called the local service today, and they said they're not even sure they can service plasmas because they haven't done it before. Uhh ohh, things aren't looking too great from the start

Can you say how to determine the production date of a Panasonic plasma display? I've poked around the back to the display a bit looking for the production date, and have not found it, but I might not have looked hard enough, or in any of the right places.

Maybe we should start tracking serial numbers of the units...
good idea:
someone might want to start a new thread for this purpose
I think we need to get the attention of the higher ups to get this issue resolved

It's on the little plate on the back that has the serial number.

I've had mine for almost 8 weeks, no problems.
production date is June 2003. I swear if this
jinxes me, I'm gonna be so pissed!
