Hi, I have bought a second hand MX4002 beo4. The picture is somewhat darker, than I would expect, with settings for brilliance, colour and contrast set to normal (32, 32, 44). What could be wrong? Erik

Clean under the contrast screen

If it has been used a lot, the tube may have lost some of its brilliance. Just crank the values a bit higher if you like it better that way, they are just numbers at this point. And if you're comparing to some other TV set, remember that B&O's with a contrast screen usually appear darker - they don't need to be that bright.

But seriously, if the TV came from a smoking household, the inside of the contrast screen and the tube surface underneath can have a horrible brown coating. Cleaning them sometimes makes wonders to both brilliance and sharpness...

For reference, the contrast screen just pops off. Very gently, push a small flat-head screwdriver under the little notch at the bottom of the screen in the centre. You'll be able to lever the screen out a little (being very gentle so you don't scratch it) and then it just pops out at either side.

It's worth giving the CRT tube itself a dust too...

Thanks a lot!

Could it really be that simple?

I will give it a try.

I have a LX2500 and a LX 6000 and they do both have a much brighter picture with standard settings, but it seems as the contrast screen in itself is darker for the MX4002, which came form a smoke free environment...

Hi,

 If its your first tv with a contrast screen they do at first appear darker.  It took a few weeks to get fully used to mine!
