    Hey guys, I have some news on my plasma repair. The new power supply board arrived and the tech came over to install it today. Upon installing it, we got power to the TV. Progress. However there is a flashing red LED now. The tech determined that’s an issue with the scan board and the buffer boards that control the image on the screen.

    He took the scan and buffer boards as he wasn’t able to diagnose it exactly, the tests were not showing an obvious issue. So he took them to test in his own Panasonic plasma. He has the same set. Once he knows which board, then we can order a new board. This is getting a little expensive, but if the scan board and buffer board replacement doesn’t work, and I say stop, then I won’t be charged for the parts, just the labor. So that’s fair. I’m thinking this is it, if this next step won’t fix the set, then I’m stopping. Which would be a shame. I know some will find this too much money spent on fixing an old TV. But given how good the image is on this set, I still want to try to save it.

    Hopefully in a week or two, I’ll be back with news, good or bad.

    On a side note. The tech said that the most common issue he’s seen on OLED TV sets are the screen itself going out. That is game over. Those can’t be replaced. So it’s new TV time.

    Guys, if anyone cares, a short update.

    Today the TV repair tech came over with a new power supply board that powers the scan buffer board. Previously, he thought the scan buffer boards might be the problem, but felt the power supply board that powers the scan board was suspect. He checked the scan boards on his bench and they were not showing an obvious problem. So he ordered a power supply board for the scan boards in case.

    Turns out the power supply was ok for the Scan board. There was one connection he left off the main power supply board from the last time. It looked like an honest mistake as the guy was really particular and methodical, good he caught it. There were still 8 flashes from the LED which still means the problem is still the scan boards and the two smaller boards that attach to the edge of the plasma that powers the images. Since he said the main board and power supplies are all good now, that leaves the boards on the scan boards. So he’s sending those back to Panasonic to diagnose them. In this case, he can’t repair them himself and Panasonic has a facility that will refurbish the parts if they are faulty. Hope that in a week or two, he gets them back and we can try those. Hope this fixes the problem. ( Sounds like a fault in the AE-35 unit. )

    So far I’m only out for the $125 original visit to diagnose the TV. I know this probably sounds like a big hassle after three visits, there is still no solution. And it has been a hassle as I haven’t been able to watch any blu rays. So my pile of movies is getting larger. But I think this guy really knows what he is doing. He can only do so much as the parts are what is holding us up and determining what is bad.

    In the mean time, I’ve been researching the new upcoming Sony OLED and LG OLED’s too.

    I've been reading your journey with great interest, and I admire your loyalty to your plasma. I have to say it doesn't sound optimistic, but I'll continue to cross my fingers for you.

    BTW, I went from a plasma to an OLED and found the experience very pleasurable.

    Hey Matt, thanks for the kind words!

    What keeps me going is this plasma is only 7 years old. Its just not right for such a pricey TV to die so soon. I can understand your feeling that the chances are low that the TV will be repaired. I appreciate your crossed fingers! I hope to report back good news!

    Thanks for the update Nelson!

    My Panasonic plasma is from 2009. So far it is running fine.

    However those 007 UHd films are coming in February 2020, so... I’ll eventually want to go to UHd Oled too.

    Thanks Josh, Osato!

    I hope you get your plasma fixed Josh! And Osato, I hope your Panasonic keeps going!

    I’ve been watching the tech and getting to know the internals of my TV now. It’s been open so much. :)

    Well, I lost two of my beloved Pioneers plasmas in a matter of a few days.

    We moved our 43-incher and the old 780p 50-incher (I mentioned in Post #2) to Corpus Christi from our house in Houston a month ago. All our stuff was moved in a U-Haul moving truck, but our two Pioneer plasmas were transported in our minivan.

    We just moved from our little apartment here in Corpus to a 1930s-vintage rent house last week. When I put the 43” on our master bedroom dresser and plugged it in, there the usual internal “click,” but it wouldn’t turn on. Certainly not happy about that, but it’s not a big loss since there’s still the other 50-incher from our apartment.

    A few days later I put the 50-incher from the apartment up on the dresser and plugged it into the same outlet, and – nothing. It won’t turn on either! Not even the internal “click.” Now I’m really not believing this! We’d been using that TV in our apartment for the past year, and a few years before that back in Houston with no problems. Did it really die on the half-mile trip from the apartment to the rent house??

    I checked the outlet with a VOM meter and found nothing out of the ordinary, except that there is no functioning ground (it’s an old house). On a hunch I checked to make sure was no “rogue” voltage present on the ground connection, but the meter registered none. Do these TVs live or die based on a grounded outlet? The old 720p 50-incher is working fine in the living room on an ungrounded plug.

    I guess our dilemma now is what to do. I’m not averse to buying used – in fact I got all three of them used. But these TVs are getting hard to find. So I guess I’m willing to spend as much for the repair as it would cost to replace it with another used one, which is probably $3-500. (I paid $1100 for the 50” back in 2012).

    Regards,
    Wayne A. Pflughaupt

    Wayne, sorry to hear about the troubles with two of your plasmas. I hope that you can resolve the problems. Could there be an issue with a fuse inside the Pioneers? It does seem odd that two go out. Maybe it’s something really simple.

    I’m still waiting on my Panasonic to be repaired. The latest news is the tech said that the boards he took out of my set, the scan boards, were checked out at the Panasonic repair center and found to be fine. So the technician is at a loss. He said the trouble is pointing to the scan boards. Hopefully next week he gets the boards back from Panasonic and reinstalls them to see if he can get the set going.

    It’s now about two months since my plasma died and I’m really missing the ability to watch a movie on my Home Theater set-up. I have another plasma in the kitchen/family room, but no surround sound and no proper seating. But it’s making do, but I’m saving the new titles for when the system is repaired. Maybe in a week I’ll have some good news.
