Are you getting any IR in or outside the green area?

I ask because in the 2011 models there appears to be
some correlation between the area of the blob and IR.

An extreme case:

Green Tinge Fault - Panasonic (VT30, GT30 and ST30)

Note also that on gizlaroc's panel the blob disappeared,
but at 2k hours it was getting IR in the surrounding area:

Panasonic VT30 Owners thread Part 9

There's something very curious going on here. That was,
of course, last year's model, so yours may differ.

I wonder if people with blobs or bands could check on a
greyscale screen where the defect shows to see if there
is any hint of IR.

For DSEB you might try a 30 IRE greyscale field and adjust
contrast and brightness until the band shows (assuming it
does). And perhaps leave some bright text on the screen for
30 seconds or so before testing?

No IR that I have noticed. This green tinge does seem different and looks to have faded a bit today. Others have said that it has faded quite quickly so I will continue putting the hours on it.

To see if DSEB is in any way related to IR. On the GT50 I tested, the DSEB
band appeared most prominently on a 30% grey image, the same grey image
that revealed faint traces of IR. Both the band and the IR disappeared when a
20% or 40% grey image was shown. Moreover, the IR appeared to be a grey
of the same level of intensity as the band.

So is DSEB related to IR or is that a complete red herring?

I'd say it's a red herring as the band was visible on my set the minute I turned it on.

My 50" GT30 has gone back, exactly the same problems as a lot have been seeing in this thread (moving camera during football etc.)

My only problem is, the people I bought it from have said, if they can't "see" it, they'll send the TV back to me at my cost.

You'd have to be blind not to see it to be honest, but hearing Panasonic say this problem is within spec, makes me awfully worried!

Bumtious said he would post an update about the fault this Friday, so hopefully we will know more about it come tomorrow. Also my contact at Panasonic is away till Monday week so I will hopefully hear something too.
It is annoying when retailers are like that. They make you feeling you are making things up. Because will all love boxing TV's back up and returning them!!

Video the problem & send a copy to them then they can't deny seeing it.

Im pretty sure sales of good act will cover you if you feel your purchase is not fit for use. Tbh if i came across a company who when faced with a return spoke to me like that. A paying customer. I would report them to trading standards for a) selling defective merchandise then neglecting their responsibilities as such and for the manner in which they do business.

May sound over the top but i cant stand jerks who try to treat customers like crap. Its not even as if it would be a big problem for them. They will have constant deliveries with their supplier. They just contact them and get it sent back on the next delivery they get their money straight away to cover the tv as theyre a legitimate business that has a long standing contract with the supplier. Then the supplier return it to Panasonic.

Panasonic may supply them directly. Thats even easier.

Stand your ground. No company wants to give money back

Well to me thats a keeper as you have only a hint compared to alot on here. You wouldn't know about it on your panel if it wasn`t for this sight. Do you see anything in normal viewing? Wait to see what the man with the amazing curtains bumtious says about any issues on Friday.
Millsey still waiting for his fiddy.

I've the magenta/green tinge problem and no, no particular issues with IR.

I'm going on running hours on it to see if the problem solves itself. Technically speaking, I expect the green and magenta tinge to "equalize" because of the illuminator being burned unevenly.

We'll see.

My VT50 is the same. The magenta make the band stand out more. What annoys me is that some screens do not have the green and magenta tinge. My original did not!!

I now have green patches at the edges of my GT50 and magenta in the centre to go along with the DSE. Only noticed it yesterday when updating the software.

JL are already swapping the set out due to the DSE stripes that I have running down the far left of the screen so I haven't notified them of this yet.

I like the way they have handled things (I'm biased as I used to work for them though), this is my second GT50 that will be replaced, I am also having a problem with a new leather sofa and so far they have swapped out two cushions and are due to swap a third. Will have to see what they do if the next tv has problems though.

I have it on good authority that production of the 50 series of panels was put on hold, while the Vertical Stripe issue was investigated...my daughters manager is from Checoslovakia...and her brother is a line manager in the plant, I asked her to ask him...so there is hope that the next shipment should all be spot on. My IR has now dissapeared it was due to orbiter being on Auto instead of on, the scrolling screen is actually poor at removing it, try it in Analogue with picture mode Dynamic for ten minutes, cleared it all..

Hi. When you say analogue you mean analog channels from uhf/vhf simple channels? Or digital mpeg4 channels?

It's very very very shallow, even using slides. But my trained eye can recognize it. Btw, it's going better and better, hour after hour.

Nobody noticed it until now.
