Default Sony Multiscan 400PS Monitor

I have been living with this monitor with the failed IC007, CXA2043Q,
for more than 2 years. Now I have got a different problem, please
have a look at this picture :

Could anyone please let me know as close as possible the source of
this trouble, or still better, if you have the schematics for this
Monitor, let me know which area of the circuit board or what component
to look for. Any help would be greatly appreciated.

I also like to know if this new symptom in anyway connected with the
failed IC.

I have been thinking of practicing soldering the SMDs but it seems I
now have to bite the bullet and practice soldering SMDs before I
tackle this IC.

That picture looks like what a failed CXA2043Q could cause. I suspect
the partially failed IC just got worse. It might be worth checking
for bad caps in the power supply, but the CXA2043Q is the most likely
cause.

It's not too hard to replace if you have a fine point tip and a
temperature controlled soldering iron. Use a sharp xacto knife to cut
the pins off at the IC's body, then remove the pins from the board and
clean the pads with solder wick. Be careful not to cut any circuit
board traces with the xacto knife. Practicing on a scrap board is a
good idea. Removing the old part without damaging the board will be
the hardest part.
