Jorge,
Better look for coolant very carefully. I have one in the shop right now
that started with exactly that symptom then died. Coolant leak onto the
signal board...not much but it does not take much. Ask if the set was moved
recently.
The signal board for these is NLA, BTW. If it is not repairable have the
cust talk to mit cust relations.
The main tuner is usually the longer one which has stereo on most dual tuner
sets. In this case it is so and the main is tua01 part #295p482010 generic
tupe eng26801d.

I am working with this set at the customer's home
The main problem is a video distortion and almost
lack Y component, just like older Mitsubishi sets using
the (in)famous pip board. But this one does not have a PIP
daughterboard, actually, its PIP works perfect, and the auxiliar
inputs work perfectly as well, the problem only shows up at
ANT A and ANT B, main picture, you can set the PIP to either
antenna input or connect a DVD to aux inputs and the signal
quality is perfect..either the main or the PIP picture.
So I deducted one of the 2 tuners was bad
(IF and video detection seemed to be inside the tuners) but
I DO NOT HAVE THE SCHEMATIC, AND CAN NOT TELL WICH
ONE IS THE MAIN TUNER just by looking at it.
After much doubting I decided to connect the customer's cable
box through AUX 1 and let them (almost) happy, watching their
favourite programs, while they wait for the definite solution.
Can anybody help me please taking a look at the schematics
and telling me which one is the main tuner, the one with the
Sony audio decoder inside or the other.. (think they are
U01A and U01B) or give me a tip on this problem, it might
even be a video switching problem.
TIA, Jorge
