Lets try this again!

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

Just got two 50" units in.....not 50 units!!

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?

Drop the quid for the lamp, at least you will have one as an test item.
Follow the diagnostic procedure in Thomson's service literature to diagnose
if it is the ballast, lamp, controller, or light engine.
Lamps and ballast assembies need to be closely matched with appropiate
controller circuitry to power them in a "test" jig situation, inclusive are
the safety conserns regarding the HV,Etc being generated..

Take the training materials that comes with the service CDs or on
their site for that chassis. It does have troubleshooting sections on
their techanical section.

And obsverate the TV to see what it is doing. Like trying to spark
lamp? DLP TV *will* flash the LEDs error lights too. Etc etc. The
lamp is HID and does produce strong UV, so don't operate lamp out of
it's chassis and lamp needs beezey air to keep lamp cool. The
training part will tell how to do the checks/diagnoses safely.

Cheers, Wizard

Assuming the training manual troubleshooting gets you nowhere and you
have tech support go through some additional help then:

Since they are warranty, order a lamp, ballast, and light engine and
charge them for it. If you need to get Thomson FSE authorization to
get the parts ordered then do it. If they won't do it that way, have
them replace the darn things.

You are ASC...!!!!!!!!.
You best start reading Thomson,s Trouble Shooting Guide.
Have fun..
