I know I have brought up the issues I have had with my Beovision screen far too many times (Back light bleeding) but I now have this rather odd round bubble shaped marks on the screen. I'm guessing its more back light bleeding? I am just interested to know if it is? Never seen that ever on any tv.
Picture below!
Livingroom: BL3, BL11, BV11-46 Kitchen: Beosound 1 GVA, Beocom 2 Bathroom: M3 Homeoffice: M3, Beocom 2 Library: Beosound Emerge, Beocom 6000 Bedroom: M5, Essence remote Travel: Beoplay E8 2.0, Beoplay EQ, Beoplay Earset
are those marks constantly on one position or is it dynamically moving?
Did the screen get some physical stress/damage, maybe a ball from the kids or a flying Nintendo Wii remote from the adults? :-)
Looks like delamination of the layers of the screen, between the pixels and the front or similar. Either due to physical stress (impact, etc.) or a defect in the screen itself. I've seen similar in LCD computer monitors that have been hit or otherwise physically stressed. Saw something similar on a monitor that was used in a laser lab I worked in, a beam reflected from the surface of an optic got routed off the laser table and hit this monitor dead center. We noticed the surface was warm and this huge delamination had started around it. Good thing it wasn't the full power beam or it'd have melted a hole in the monitor, but it did look similar to this, albeit perfectly round.

I'm afraid I'm recovering from the BeoVirus.

Yes, it looks rather like heat damage to me as the bubbling effect is similar to how a flat sheet of plastic would look if exposed to excessive heat, but it is really difficult to be certain from a photo. If it is indeed heat damage and if external heat sources can be rules out I'd be suspicious of a failing / overheating component behind that part of the screen but we're really just guessing...

It's a Beovision 7-32 mark 1. It started as little dots then grew and grew. I think there are tiny little dots starting on other parts of the screen although I'm not sure yet. I think the main one is still spreading. Quite heartbreaking as a replacement beovision is virtually impossible to find in my country and a new one far too expensive.
Thanks for all the answers though.
