Good news: My repair shop is on the way with a replacement set.
I'll give an update once it's set up, Then I'm off to the VT60 threads.

Congrats!

Hopefully the VT60 will do what I wanted this one to do: have the best PQ on the market until a 65" 4K oled can be had at a reasonable cost.
4-5 years maybe?

Hey guys, I figured I'd give an update on my VT50. For those who may remember, I had the yellow blob issue back in June/July and after a month of dealing with Panasonic they replaced the panel on my set in August. Well, just like jcm had happen with his, a couple weeks back I noticed the yellow blob on the left side returning. My warranty expired October 6, so i didn't have time to wait for it to develop further. I called Panasonic up and last week had the same service tech back at my house. Things took a turn for the worse, however. This time the service tech I had walked in with an attitude that nothing could be done. I wanted to show him a few examples of the issue just as I had last time, but he told me he didn't want to see them, because Panasonic only wanted pictures of the service menu. Now, even in the service menu you can just barely see the blob, but he kept telling me he couldn't see it. Mind you, I've had two friends over who both said they could see it before this appointment. The service tech then called up a senior service tech on the phone who explained to me over speaker phone that plasma tv's never will produce a true white color and to just let it go. Long story short, after about 20 min or so of debating with the service tech, I finally got him to call Panasonic and continue with the warranty service. He complained that he was going to have paperwork to do now, because I forced him to call Panasonic. So, its in Panasonic's hands now, but honestly I don't have high hopes. I'd guess the service tech I had probably told Panasonic that nothing was wrong with the TV and to close the case. If anything more happens I'll update, but I think I'm stuck with the blobs.

Update on my case. The 3rd Party tech came out, they left the loner as I had mentioned in my last post (last Wednesday). The 3rd Party Tech urged me to keep calling Panasonic to expedite the process. I called on Sunday and there were no updates. I called again today and the "exchange" was processed on Monday and I should be receiving the new unit within 10-15 days.

I contacted the service center that is coming next Monday to confirm my appointment and ask if they've seen the yellow blob issue. I want to know how much trouble I am going to have to go through to be able to reproduce and document the issue. Hell, if he says he can't see it for some reason, I will use my meters to measure that part of the screen and show that it measures yellow. I'm sure the tech would like that. I guess I am being so glass half empty is because this company who is coming has some pretty negative reviews on Google; Video Tech Center, based in Maryland. We shall see.

The lady I talked to went to speak to somebody when I asked if they have seen the yellow blob issue and she came back a couple minutes later and said they haven't really seen that issue. Their solution is to replace my a-board. What are the chances of that fixing it? I'm almost out of warranty and I don't want the issue popping up right after my warranty is up on November 4th.

As I mentioned in the other thread, the WOW disc really shows it well. Is it noticeable in the pictures below? Also, I have to lower contrast to between 63 and 75 to prevent white clipping, I don't ever remember having to do that in the past. Could this be a side effect of the whole issue? Lastly, I am getting ridiculous image retention. I can't have anything on screen for more than a minute from the WOW or S&M disc without it causing temporary (hour or two) but easily noticeable IR. I love the VT50 but it seems to be going downhill quickly.



Identical to my issue. That is clearly visible on your pictures, good job.
post #427 of 977
Nice, even though the remote buttons have been moved around.
Great to be rid of that blob, which showed up particularly well on
this webpage.
I like that the ISF modes don't need to be unlocked.
So far, running THX mode, may try some other stings once I find them.

I am curious to see if the ST60 and VT60 will develop the globs over time. It took a while for them to show up on my ST50. I have over 3000hrs on my set. I would say it started showing up after 1000hrs. Time will tell if the problem has been fixed on the ST60.

I had a similar issue to this back on my SXRD with the famous green blob issues. After a few replacements of the optical block the tech finally told me that's how they are, there's nothing wrong with the tv. This was under BBs warranty service, so I called them, explained the situation, and eventually was authorized for a dispute claim. Mind you this was a near month long battle. They sent out a completely different service company to verify if the part was defective causing blobs or if the original tech was right in which I would then owe $125 for the trip charge. The new tech walked in, looked at the my tv for half a second, and immediately was like "ya, the optical block is clearly defective." He then got BB to buy it back from me instead of replacing the part again like they were trying to do. I then used that credit to buy my VT50 and as coincidental as it could be, the VT50 now suffers a similar issue. Ah, lucky me! Fortunately, I have not seen any problems yet, but I'm on the lookout. My VT50 turns 1 this week (they grow up so fast!), and has about 600hrs on it. If the problem does arise I'm hoping that square trades warranty I bought will cover it and that the whole tv gets replaced with a VT60 or newer depending on when the failure may occur.

Damn! That's the kind of bad luck none of us want to run into. I guess I should be happy that Panasonic never threatened me with a charge if nothing was wrong. As a funny coincidence, a few hours after my post yesterday I got a call from the company servicing my VT50. They asked if I could send them a copy of my receipt for the TV, because Panasonic is "considering" a replacement. There may be light at the end of the tunnel yet. Keeping my fingers crossed.
post #431 of 977
Panasonic is replacing my vt50 next week. Thankfully my process was relatively painless. It took less than a month. After customer service had me reset the tv ect and tried to say it was burn in, I offered to send them pictures myself so they could see first hand that it wasn't burn in. Hopefully the vt60 won't develop this issue. On another note I wonder if my square trade warranty will transfer to this set?
post #432 of 977
You will have to cancel your warranty, should get at least a partial refund back tho

I have 1122 hours on my 65VT60 and there are no screen uniformity problems. (So many hours because of a disabled person in household and the TV is on at least 10-12 hours a day.)

When Panasonic replaces a TV under the one year warranty do you get any extended warranty on the new one?
post #435 of 977
Some grumbling on the VT60 thread about the increased fan size and noise.
Bet those fans are there to combat the yellow stain.
post #436 of 977
What does the a-board do? I have searched for "a-board" and that comes up with far too many results for me to sort through. I would like to be able to avoid the tech even attempting to replace the a-board if at all possible. Maybe if I understand what the a-board's purpose is, I can explain to the tech why it won't work for this issue and/or have other evidence for him that it would be a waste of time to replace the board.
post #437 of 977
I finally got around to calling Support back about my yellow blob issue and the rep I spoke to asked me to take photos and send them via email.

So here's my question:
In everyone's personal experience, what are the best conditions in which to capture this? I certainly notice it almost everytime I look at the TV with a whiteish/greyish image on the right side, but I want to be 100% sure that what I send in to support is noticed by their techs.

Any suggestions? I know to let the TV warm up, wondering if I should also just let my room warm up some to increase the temp a little bit.

Thoughts? Thanks everyone!

I had some minor off white (looks almost like a yellow tint) spot about 12 inches high and 6 inches wide with a sharp cutoff on the top and more random and tapering off towards the bottom side on the upper left side of my screen. It had some bad menu IR only in this spot but no where else at all which seems kind of weird. Anyways, I wish I had a decent camera to take a picture. Watching regular content did not even begin to help, so I pulled out my Disney WOW disk with the pixel flipper Java applet that turns on and off the pixels evenly at I think 24 or 29 fps. After running it for a few hours, the screen is completely evened out now and I don't see and discoloration at all except for some really minor dirty screen effect from the anti glare coating. I'm kinda worried that it might happen again.

I have to admit, I hadn't checked for IR recently and probably had the menu up quite a while at different times going through all the options so I guess I wasn't too surprised by the IR but what did worry me is it was only in the off colored spot. I kinda wonder if the spot starts out small and starts to spread out over time. I'll have to keep an eye on it because my warranty is over on December 5th of this year. Although I have an extended warranty for 2 more years, I would rather deal with Panasonic directly if something does go wrong.
post #439 of 977
Well, the tech just left. It went completely opposite of what I expected. This tech was experienced and when I showed him the issue he knew that the a-board would not fix the problem. He then called Panasonic direct and the person at Panasonic was terrible. He was forcing the tech to go into the service menu and adjust the white balance and everything. It took like an hour. The tech was looking at me and rolling his eyes because the guy on the phone was so bad.

In the end, the Panasonic person told the tech to check with the Panasonic parts department to see if the panel is in stock so that it can be replaced. So, the tech will call me back when he finds out if the panel is in stock. It wasn't exactly the outcome I was hoping for (which was VT60) but I haven't lost hope for getting a VT60. Anyone venture a guess as to whether or not they'll have it in stock? I remember reading that Panasonic has a new panel replacement policy but I don't remember what the policy was.

The A Board is the board which has the video inputs HDMI, USB, ethernet etc on it. It also has the main video processor and the "plasma AI" which controls how the display panel is energised, sustained and written to. It's possible a firmware update is coming with the board which could possibly fix some yellow blob problems -- but there's no reason I could see why that couldn't be done with the USB port.

Received my new VT60 today and she is a beauty. Instead of delivering to the service company they delivered right to me via Averett trucking. It came on a pallet and attached by shrink-wrap. No visible scars to the packaging and the TV looks great. Starting to run slides now.

Congrats...Who's next??
post #444 of 977
Not me!!! I'm already in the vt60 club. Chad calibrated it yesterday. I had him at my house three times in the last year:eek:. I do miss the extra light output of the vt50.

Just to recap my saga, I had bought a 55" GT50 and there was a visible kind of semi transparent line on the ride side of the screen. It eventually developed the yellow blobs after about 4 months. I went to Bestbuy and exchanged it for one of the last VT50s they had in stock, it too had a semi-transparent line down the right side of the screen (extended warranty). After just two months the yellow blobs appeared. This time I called Panasonic because there was no way I could reproduce the VT50 for the price I paid for it. I received the VT60 today, and I an happy to report there is no semi-transparent line down the right side. I am hopeful that this TV is what I had always expected I would be getting.

I would like to graciously thank this forum for the visibility into this issue and giving me the guidance and ammunition I needed to get my TV replaced. I am very grateful and thank you all again.
post #446 of 977
Looks I drew the short straw with my repair. I called the local tech place to get a status on whether or not Panasonic would be replacing my panel or the TV. I was informed that Panasonic is replacing my panel instead of the TV. The tech place is waiting for the part and it will be here next week. I am a bit bummed but as long as my TV gets fixed...

Exactly. Short straw would be if they told you they werent going to do anything. And you may still get a new tv if the panel doesnt work.
post #448 of 977
Geek Squad came out to take a look at my ST50, the guy said they are going to order a panel to fix this issue. Hopefully the part will come up canceled so I can get my TV swapped.

Is it possible the panel won't work or is a new panel likely to fix the issue? I'm worried the issue will pop up again and I will be completely out of warranty or any coverage.
post #450 of 977
That is what happened to a couple of folks with this issue, they had the panel replaced and it developed the same issue. I was told by the service tech that it is fimrware related but they did not have a fix as of yet. If that is the case you may be in the same boat as you are now in a couple of months. It is disappointing that the service response is so inconsistent.
