Have not managed to check this on mine ... what software version is in the TV? To remove the screen ... if its perspex, put your finger nail under the bottom in the middle and pull out ... that's the simplest way. To replace ... insert one side in ... then flex screen and then insert other side. Neil

How are you adjusting the stand on the 4000 .... with the stand option on the beo4 or with the on screen menu or is it an early one where you have to cycle the picture options on screen until it says sound? Acrylic screen replacement is easy ... the glass ones are tougher. I wouldnt quibble over the auction ... you got a good deal, even with it not

A tube from an LX5000 will fit ... but needs some modifications ...

Its possible that it has developed a fault and wont come out of standby to avoid further damage to the set. Where are you based ... someone on beoworld may be able to help. Neil

I have a white beovision 600 from 1971 ... I am sure that this was not the "first" product in white

Can you confirm that this is an LX2500 ?

You are correct, it should not need the BM present. A common failure of these is the death of the laser ... Neil

OK, let me know ... but unless you know what you are doing around a tv, I would not attempt a fix yourself. Neil

Yes, indeed.

Sounds like a component failure which is preventing the correct start up of the TV. I am in Farnham, Surrey, UK if you are close by and would like me to take a look for you. Neil
