    I have been given a Sony KL32-W3U which has lived its life in a pub. The picture is drab and the colours lifeless. Having wiped off a century of nicotine from the cabinet I was thinking that the lamps are dirty.

    Anyone got a step by step guide to cleaning one of these sets?

    There's only one lamp, and you can remove it yourself (behind the speaker grille, front bottom right) to see it. Clean the "output" end of the lamp if it needs it. It's user replaceable, although new ones cost GBP300 or so.

    Probably, the whole of the optics inside the set have been coated with tar, too.

    You can safely remove the entire top of the set, down to the bottom 30cm or so. Remove screws at the back of the set to do it. Hard to describe exactly, but you should be able to work it out.

    This piece is quite light and contains only the screen, a mirror and a lot of empty space.

    Clean the back of the screen (inside) and carefully clean the mirror. Try your technique on a tiny area in one corner - you don't want to damage the reflectivity of the mirror.

    If you then look in the base of the set, right in the middle, you should see the projector lens. Whatever you do, don't move it (ie. change its focus). You can clean the top surface of this.

    There are probably other, more enclosed, areas (like the LCD chips and/or the prism block) that are coated, too. But to try and dismantle this area of an LCD projector is never a good idea, so - don't. You should get some improvement from the above.

    When you put it back together, check the air filter behind the grille at the front left. Clean and/or replace it if necessary.

    Mod comment As this isn't a DLP set, but an LCD rear projector, I'm moving the thread to the LCD forum.

    kourosh - you're clearly thinking about the wrong kind of TV.
