this model is famous for fluid leaks. each projector True True (``````````` (``````````` 0 95250 95250 tube has a reservoir on the front of it with a fluid in it. this keeps the face of the tube cool.
this depends on how bad the damage is in the tv. in most cases we can reseal the tube and clean up the fluid 400-600.
take the tube out you will see where it leaked. The problem is that the
frame on the CRT that the heavy screws with springs are mounted on (that
hold the lens coupled to the CRT) is weak and they can bend. We have seen
several that have leaked after the customer moved the set. You can only
tighten them down so much because the frame bends. It is just stamped metal
and not welded at the corners to support the bend.
We remove the CRT, clean it all up, add a very small amount of RTV sealer to
the gasket, reassemble, let the RTV cure thoroughly and refill with coolant.
The extra sealer should prevent future leaks. Haven't had a recall yet.
Mits says replace the CRT...too costly.
You msut check the yokes carefully as well. If any coolant gets into them
you can end up with shorts there and a mess.
Here's something that might also be useful. After you turn on the set, and get the regular red blinky lights, hold down the Device and Menu buttons together for about 5 seconds.
The Power light will start to flash in a two digit sequence.
For example, 3 flashes, then 7 flashes = 37.
Here are the error codes, and the corresponding problem:
12 = No error detected, check power supply.
32 = Lamp Cover is open.
33 = Air filter cover is open.
34 = Lamp abnormality
36 = Light Engine (DMD or Lamp Fan stopped)
37 = Exhaust or Lamp Ballast Fan stopped
38 = Lamp Temperature High
39 = DMD Temperature High
41 = Short is detected
44 = DVI cable between FMT and Engine disconnected
