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.

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?
