Hi all,
Hope someone can help me?
I recently purchased a Beovision 7-32 Mark 3. Fairly good price too!
Once home, I noticed when not in operation (black screen), there's a few areas of what I can only describe as misting / fogging. Mainly in the bottom right and left corners, with a faint one in the centre from the base.
I've been advised!!?? that this may be condensation trapped behind the screen, maybe whilst being stored or used in cold temperatures previously.
Question is: How much trouble and is it possible to remove the screen, clean it and re-assemble??
Is it an engineer job or DIY?
As I mentioned it didn't cost the earth, so didn't really want to spend heavily.
Apart from that it works great and the picture, when on masks the misting to an almost unnoticable level.
Many thanks in anticipation of a little help and advice.
Regards,
Richard
Hi Richard
Before resorting to removing the screen, pull it forward slightly and wedge a piece of cardboard behind the glass screen.
It is held in place with springs so will move forward with a small amount of pressure. The cardboard will allow a gap for the mist to clear. Once the mist has evaporated you can remove the cardboard.
Can happen when sets are transported from very cold temperature to indoors.
The condensation doesn't usually come back once it has dried out.
Good luck.

As described, the heat from the TV should help clear the humidity. The gasket seal should reseal once the card is removed and hopefully it should be as good as new.
The contrast screen can be removed but it's a job for a tech really as it involves undoing retaining screws from inside the TV to release the contrast screen to allow it to be lifted off. Not for the feint hearted and not worth risking any damage. Any flaws in cleaning will show up once it's back together too so best left to a tech from B&O if it's necessary.

Hi Opman,
That's really sound advice. I will give this a try tonight. Certainly much easier than my alternative!
Would you not switch on until it's cleared? Better to dry naturally, whilst switched off?
Thank you so much for your advice! Really appreciated.
Best regards,
Hi Dave,
I really appreciate this. Goodness knows how you know this, but I'm very thankful to you.
I will give it a go tonight / over the weekend.
Did you think powers best left off whilst cards are in?? probably a silly question!?
You mentioned the heat would aid the drying, but not sure if it can run whilst cards are in place.
Thanks again,
I've never done this so can't say 100% but another member with the same problem with another LCD screen was advised to turn the TV on to speed up the process. Your call. The card is only to barely open a gap, not pry everything apart and risk damage to the seal or glass. The longer it' takes, the more risk you have of allowing something else in there - dust, more condensation on a cold evening, moths etc! Heat should in theory expand the air a bit, then when you take the card out it should form a small vacuum on the seal to help seal it tight when the air cools - just a theory but sound principal.
The Forum and workshop/service manuals are very helpful.
I de misted our Beocenter 6 by leaving it on for a couple of hours. Only a little misted but it fixed it .
