    Just fired up my DLP for the first time in ages, and there is suddenly a chunk missing out of the display! A thin line running from the bottom, about a third of the way in, up to about mid point on the projection. Not too wide - about 5 percent of the width?

    What on earth has happened? Is this fixable, or expensive? Any help greatly appreciated!

    Try flipping the image to see if it's the DMD or not.

    If the line moves from bottom to top, then the DMD is fine, if it doesn't, then it could possibly be the DMD. A new DMD for something like a Davis DLS8 is around £1300 IIRC.

    It could be the formatter board or possibly firmware.

    Has it been apart at all? It's possible that some connections may have come adrift which could cause a similar fault.

    Does it change at all during a film, or is it just black/blank?

    The line moves form top to bottom IIRC. New firmware maybe? Could I find some way of flashing this at home?

    I'll open the sucker up and poke around connections if required.

    Thanks for your advice - appreciated sir!

    Dont most of these suckers have 2/3 year warranties on them?

    I'd check - the warranty that the retail outlet may say you have and the warranty the manufacturer will give are often two different things..

    Hope ya get it sorted..

    The warranty is a good point. Some pjs like NECs have a 3 year warranty, so it may be worth looking into that.

    It sounds like the DMD is OK if the line moves when you invert the image. Don't open it up just yet, as it may make things worse. :)

    Have you checked that it does it on all inputs, and with different sources?

    It might be the input. Check to be sure.

    Gary.

    Have now tried all inputs, and they all display the same thing unfortunately. Most upsetting, I can tell you.

    Anyone got any more dieas? Or am I going to have to take the little blighter to an electronics shop and actually pay for something :( ;)
