uniserver....

1) Yes, I tried what you suggested.
2) No, I am not rough with my electronics

3) Tried that.

I sent you my good, working, analog board  from my working Color Classic.  You said you would replace the bad caps. You told me old solder joints some time fail and you fix them.  It failed with in 48 hours of returning to me.  And no, I had no cut wires in my color classic analog board.  I know enough electronics to not man handle anything.  I re assemble the color classic on my work bench with a static wrist band on.

I rebuild old vacuum tube motion picture amplifiers for a hobby.  So I know how to assemble and re assemble correctly.  I do not know modern electronics with chips and flat packs.

I took the color classic apart again yesterday afternoon.  I pulled the analog board.  Just eyeballing it I could not see any cracks in it.  I use compressed air on the socket before I plugged it back in.

After I re assembled it, I still have to same issue.  I need to trouble shoot this problem in or out of the analog board.

Did you replace all the bad capacitors in this analog board?
