Thanks for listing the cap comparison below.
Problem is, this only happened recently, long after I had
changed the power supply caps - after which everything had
worked fine. I remember reading a post some time ago where
other caps were mentioned to have caused picture problems,
but the post didn't mention any specific boards involved. -Ron

Probably not anything to do with the troubles you are experiencing,
but thought I'd mention that the Sony PSU service kit changes the
value for three of the caps. Dunno how critical the correction is,
but thought it worth noting in case folks are just changing them out
with equivalents. What I recieved:

Kit: A-6759-574-A
cap# Orig. New
*C201 50v 120uF 50v 100uF
C202 25v 560uF 25v 560uF
*C203 25v 1500uF 35v 1200uF
C204 16v 2200uF 16v 2200uF
C205 10v 3300uF 10v 3300uF
C206 16v 470uF 16v 470uF
C207 10v 1200uF 10v 1200uF
C211 50v 0.47uF 50v 0.47uF
C214 16v 120uF 16v 120uF
C216 10v 470uF 10v 470uF
*C218 10v 120uF 16v 120uF
C219 50v 1uF 50v 1uF
C220 50v 120uF 50v 100uF

Electrolytic caps not in kit:
C105 200v 390uF
C108 250v 1uF
C213 16v 330uF
C215 16v 220uF
C217 10v 220uF

All of these should be 105'C rated... the old Elna caps originally
used apparently had design flaws that resulted in leaking, but were
also only rated for 85'C and these PSUs seem to normally run very hot.
C105 and 108 in my unit had also leaked.
