If I bend the circuit board the picture comes back.
I've examined and probed the solder connections on the bottom of the
board, but I can't find any that are obviously bad.
Because the picture comes back when I bend the board, am I right to
assume that it is a bad solder connection or could it still be a bad
resistor in the vertical circuit.
Can any one give me some tips to find the problem?
How can I locate the vertical IC?
