    Bad question, I know. Does RCA have a DLP problem?

    Just got two 50" units in, only out by one number in their
    serial number. Example: 1234567AB, & 1234567AC.
    One dead right out of the box, the other dead, after not
    much use. They were made in Feb 2005. Called Tech
    support, we are ASC. One guy said: Light engine bad,
    which is about $ 1,800 can, another Tech said: Lamp
    bad, about $ 250 can. What's a Tech to do? I haven't
    even seen a partially working unit yet, to know what it
    sounds like when starting up, & running. How can you
    test a DLP lamp? There expensive, & you can't measure
    them, to be sure? Can you set up a test jig, to test the lamps?

    Since you got 50 sets, you should invest in some spare parts for testing.
    The service centres try the parts to test. This is the safest and most
    feasible way to service these sets.

    Normally, the TV sets, and appliances of today are serviced at the modular
    level. If adjustments are required, depending on the particular
    requirements, you may need to invest in the proper tools, service
    information, and etc to do the work.

    If you are not properly trained and not willing to invest in to doing the
    service on your sets, it would probably pay for you to find a service
    contractor that is set up for this type of service. If you paid a good price
    for your sets, and they have some re-sale value, then they should pay for
    you to have them properly serviced.

  3. I think you read that wrong. He has TWO 50-inch sets...

    Are we reading the same thing? I only saw a reference to two sets, and
    he's an authorized service center.

    Unfortunatly it's pretty hard to test the lamps, they're DC metal halide
    or super high pressure mercury depending on the design. Both require a
    somewhat sophisticated electronic ballast which is not necesarily easy
    to get running when not connected to the rest of a unit.

    You *may* be able to get one to glow by using the driver board for one
    of those cheap little neon sculptures or something similar. If the lamp
    does anything at all on one of those then it should at least fire up on
    the correct ballast.
     
  6. Hi!
    That's probably a lot better than 50 2-inch sets!

    (Sorry, couldn't resist.)
