    I have a Mitsubishi WD-52327 DLP

    Last week I went to take a shower and when I came back the tv was shut down with the red "lamp failure" light on.

    There was no warning at all. It just failed. It didn't even look to appear dim.

    I bought this tv used from American so I can't get any warranty service on it.

    Anyway, I bought a new lamp from E-Bay (From a reputable seller) and installed it today according to the instructions.

    When I turned it on it just sat there for about a minute then it turned itself off with the red "lamp failure" light on again.

    I'm assuming the lamp is fine. Actually, both of them look fine.

    Does anyone know what this problem could be?

    I tried hitting the reset button on the front panel but that didn't do anything.

    This is very frustrating, I've only had this tv a month.

    Any help would be appreciated.

    Could be the lamp ballast.

    The ballast should be fairly modular; but you might really need a service manual to replace it yourself.

    Actually, likely the hardest part in ballast repair is actually getting to the ballast to remove it.

    Yeah, I hope that's all it is. (lamp ballast)

    If it's the light engine, then I'm probably just going to have to get a new tv.

    The "light engine" shouldn't report a failed lamp.

    Bah! Companies should splurge the extra $0.01 to add an extra LED for troubles. A LAMP LED should ONLY report for the LAMP - not the ballast, power supply, mother board, light engine, or anything else.

    Does the instructions say anything about "resetting the lamp counter"?

    On some sets the red lamp trouble light comes on after so many hours of operation. This is based on time since the electronics cannot sense anything about the lamp itself and after so many hours of use the chances of the lamp's actually exploding become significant.

    Oooh! That's a good point; forgot about that one.

    But usually, the machine will often have a message somewhere (even if it's just a cryptic icon in the lower corner somewhere) indicating that it's a lamp-counter issue.

    Well, a tech came by yesterday and ran some kind of self diagnostic on the unit.

    It came up with a code of 34 which means Lamp Abnormality.

    He says that it might be the lamp ballast so when he comes back next week (taking forever!) he going to swap it out and then we'll try it.

    Hopefully that's all it is.

    He wasn't too sure.
