Television and Home Theater

When I turn on my TV it shuts off in about 3 seconds.  I took off the back and noticed some fluid leaked on the CCAs.  I cleaned the CCAs off and still have the same problem.  The fluid was mainly on the left CCA.  I haven't checked the fuses yet.  I have a few questions:

 1.  I got an error code 23 (input-menu).

2.   ALL the fuses are good.

3.  Is there anywhere to get a free schematic or service manual?

3.  Any ideas of what the problem might be?

Seems to be a common problem with these sets.  My green light blinks for a minute then red light comes on.  Tried replacing the lamp, but problem persists.  Occasionally the screen will flash different colors, but no picture.  Would appreciate a copy of the service manual, and any ideas where to start.  Thanks, Barry.  [email protected]

This TV just shuts off on it's own at anytime. The green light stays on, but the picture just goes blue. a message on the screen says "check connections or power. The connections for RGBHV or YPrPb may be invalid". By turning the TV off and back on again, a picture returns, but then in a few minutes it goes off again, and the cycle repeats.
Any suggestions?
