Panasonic VT60 - pink on white background

I have a 60" Panasonic VT60 that looks great 90% of the time, unless there's a white background. Mainly on the right side of the screen, I see a pink spot. Although I have a Squaretrade warranty, I'm not sure if it's worth taking advantage of. Since these TVs are obsolete, I'm not sure if replacement panels are even available. I called Panasonic and they didn't have that information and suggested that I contact a local service center. Do they offer you a replacement LED TV if your plasma requires replacement, or are there still parts available? I definitely don't want an LCD/LED, and as I mentioned, the picture on this thing looks fantastic most of the time. I'm just wondering if a fix is possible before the warranty expires. Thanks for the help!

I might be wrong, but if the item cannot be repaired, then I believe squaretrade will just write you a check for what you paid for the item. The replacement is up to you to purchase if it comes down to that.

Change vsus to high in the service menu and the problem should be fixed.

I think you're correct, but that's why I'm trying to find out if replacement panels are still available under warranty.

I hope you're right, but I can't seem to find this. I'm using D-Nice's professional settings, if that makes a difference. If you get a chance, could you please find the exact section for me? I'd really appreciate it, thank you!

I had forgotten about the service menu until after I asked where to make these adjustments. For some reason, I thought it was in the calibration section. Although I haven't found the specific button sequence for the VT60, a quick Google search found the exact issue we're going through here, including a guy who was asking about panel replacement and Squaretrade, just like me:

https://www.avsforum.com/forum/167-pl...-talk-565.html

If I can't find it in that thread, I'll make a post.

This is the first time I've done this, so I don't know all the options. When you're in VSUS, you'll see the options on the top left hand side of the screen. First hit "OK" for VSUS test, then use the volume to adjust between high or low. I don't know what 3,4 TEST/CONF SELECT means, though. When I set it to HIGH, then enter 3, it looks perfect. With 4, I still see a little bit of pink. So, I just enter 3, then select "OK" to write, then hit the power button. I seem to recall that you're supposed to hit the power button on the TV itself, so that's what I did. I went back into the menu and it's still on high, so that's good.

Yes, it's easy to screw things up in the service menu, so as it states in the link I provided, be careful not to touch the volume control when you're in the wrong menu, as it will adjust values that you're not familiar with. I'm going to do some more searching tonight, but from what I've read so far, switching VSUS to high won't have a significant impact on the life of the panel. This is a common fix.

The pink spot is common. You will find that it is located at the hottest place on the panel. (Run your hand over the back cover to prove this.)

Before attempting a VSUS adjustment, clean out the fans. While the set is on, use a can of compressed air to blow out any dust that may be blocking the flow of exhaust air. Some have found that just using a vacuum cleaner over the vents works as well.

If you want to try the VSUS adjustment, the attachment will show how. I have yet to find anyone who has found changing VSUS to solve the issue.

The only way to reduce the coloration is to reduce the heat using fans. Some have attached external fans right over the TV's fan opening. I have had luck with inexpensive USB powered fans placed on the TV stand pointing at the vents to move air over the vents and dissipate the hot air coming from out of the TV.

There are no new replacement panels available for any Panasonic Plasma TV.

Panasonic didn't even have any available when the TVs were still in production in 2013 - they just replaced the whole TV instead of warrantying a failed panel.

Thank you. Unfortunately, I didn't see your post until after I had already adjusted VSUS to high. Changing VSUS to high did solve the problem, though. Now you've found one person who had positive results from changing VSUS to high! What are the negative side effects from leaving it on high? Any greater sensitivity to screen burn or anything like that?

I took your advice and used compressed air to blow out the dust WHEN the TV was on. This was a good idea. I'd also like to rig some external fans to help with cooling. Are there any threads out there I should search for that show how to rig these fans?

One more thing...I still don't understand "3,4 TEST/CONF SELECT" according to what I've described in my post above. The numbers seem reversed, according to your image. 3 should be TEST and 4 should be CONF SELECT, but it's the other way around? It sounds like I did it correctly, but It doesn't make sense that 3 looks better than 4. They should look the same.

Also, what does this mean? "Do not overwrite because data is written in NAND Flash after executing adjustment of V-SUS Voltage." I hit OK at the end to write. Are they saying not to do this too many times? Sorry about all the questions! I tried searching and couldn't find the answers.

Thank you, this is exactly what I needed to know. The only suitable replacement I'd want is an OLED, and they're still too expensive. Besides, I love this TV.

Hi all,
So I tried to clean the vents with soft wet towels and dust hovering, but the back panel is extremely hot on both side of the screen, it’s pretty hard to clean them, my screen mounted to wall.

Anyway, I changed the VSUS to high and the pink spot disappeared, in the test screen and actually on any white background.

What High VSUS actually mean? Any impact on my screen for short or long term?

Thank you

Any risk?

I have read alot about Vsus low vs high, I also have read about information from panasonic.. So I try to explain it here very short..but I can not give you a 100% accurate technical explanation..


Vsus low or high controls voltage and has something to do with the plasma cells working perfectly..


It can happen that with Vsus Low.. some pixels will turn red.. you then have to use Vsus high..


Every panel is different.. some run fine on low.. some are per default running on high..


High should always be used if there are any red pixels in white on Vsus Low..

I just wanted to say that I also had great success fixing the pink spots on my VT60 by adjusting VSUS to 'high'. The '3' setting was by far the best on my TV, like JPowers also stated. I'd say it fixed the issue by about 90%. I have no idea what any of this means but thankful for AVSforums once again! I was considering going to battle with Square Trade over this, but now content on sticking with my VT60 for a while longer.

I'm thinking of trying the VSUS high fix for for pink discoloration on my VT60, but I'm wondering if I change the VSUS setting, will that throw off my calibration? My panel was calibrated by D-Nice a while back, and I'd rather not mess that up if possible. I only ever notice the pink discoloration on an all white screen, so I can live with it if it will throw off my calibration.

Yes I believe it will. I learned my lesson with the yellow blobs on my VT50 so my warranty replacement VT60 got fans at 300 hours. I have over 12,000 hours and no blobs. It's the heat that is damaging the panel.

Yeah, Panasonic really made their later panels too thin to try and compete with LCDs - should've given them more room to breathe. I have quite a few hours on my panel, so I'm assuming the pink areas are permanent. I'm still going to go into the VSUS menu just out of curiosity, but I'll probably just keep things as they are unless there is some mind blowing improvement.

Which fans did you use?

Also, has anyone had success adding fans after the pink appeared? I have been away from the forums for a while, but my TV def has the pink blobs on a white screen.

I know it doesn't help that I have the TV mounted to a low profile mount above a fireplace, so hopefully a few USB fans will do the trick.

This is what I have. I run four on my 65VT60 and Two on my 51F8500. The link is not my company but the picture is my TV. Very nice setup and cheep. I finally had to replace my fan power supply but it lasted over 12,000 hours and is only 15 bucks to replace.

I don't use the thermostat. He added that over the USB switch that turns the fans on with the TV. I want mine to run whenever the set is on.
