Yes, the panels are on back-order...because there's isn't any. So, the only option is a replacement display (VT60) or a full refund...or so I thought. This past Monday I received an interesting phone call from the servicing company. The technician explained to me that the issue wasn't caused by faulty panels or boards but was a software panel voltage driving issue within the entire 50 series line. The technician said they just received a bulletin explaining how to update the software and tweak a few key voltages to fix the issue. Even though the plasma R&D department has been closed down, apparently they still had a few engineers still trying to address this yellow blob issue...we'll see. I was informed that the fix is not in the form of a firmware flash (yet) or just voltage tweaks alone. The technician would have to upload newly configured software to the main PEAKS board and tweak a few driving voltages. I will update you guys once I find out more info and when the fix will be applied to my display.
This is great news. Thanks for bringing it to us.
I have just been through another frustrating episode with Panasonic NZ. I sent though an update to them with before an after photos of my adjustments. I said to them that I had to do it given their stance on calling my TV within specification and not a warranty issue. I then asked if they still viewed the issue as within specification and was worried about the panel life. The reply from Panasonic was the TV is still within specification and I was welcome to contact their service agent for an inspection at my cost. Also that any repair would be at my cost.
I sent photos to their service agent who told me they have seen this type of discolouration before on both panasonics and samsungs. They said they could do nothing and that in calls to Panasonic NZ my case was confirmed to be un supported and they could do nothing to help. They also said it's the design of the TV and this issue is normal. Its due to the fact the boards are so close to the panel and can't circulate air.
For any owners in the USA worried about a bit of time taken by panasonic to repair or replace, it could be worse. I think what Panasonic USA are doing for you guys as customers is excellent in that they are acting to get a resolution for you.
For me its too risky now to buy another Panasonic in NZ. This is because quite a nasty defect is treated as within the acceptable quality standard. This is a real loss to me in that I have purchased 3 Panasonic plasmas in a row now with 2 of them being flagships. It would be way to risky to splash out on a panasonic OLED if they ever appear.
I can now only hope the software mod arrives. This would at least give me further case to take up with Panasonic NZ that the TV is not within specification. Not to me at least.
I was one of the guys who performed voltage surgery on the VSUS. I am pleased to say it is still holding up strong. My blobs are almost impossible to distinguish. I have added 2 USB fans to cool things off. The TV that is not me:D. The only side effect if I will get the odd patch of blue sparkles in the blob areas on a very orange screen. The appears on the British show Graham Norton that has an orange background. Check it out for yourself on YouTube. Maybe I have the voltage slightly high, but I think its a pretty good trade off.
I would rather enjoy the VT in glory for a short time rather than limp along for eternity with yellow blobs.
