I posted the same issue last week for a Sony KV27S26. I pasted my cure 
below:
...On the" G "power supply board, I replaced the 9 volt regulator IC
"IC641" (part# SI-3090CA, 874992058)
And  the assiciated upright black  single inline IC643 (DM-58,
874901213) located behing the 9V reg.
Set powered up with good operation. Fixed...
(In retrospect, probably just the 9V reg IC641 would have  fixed it.)
