Is this actually a model CPD-20SF2? I don't find a listing for CPD-20FS2.
Also is the yellow LED labeled SAVE? If so that indicates an ABL shutdown
from excess beam current and may be a bad CRT but check R612 and R613 to be
sure they are not open. If it is the orange LED blinking check C628, it may
be shorting to a printed circuit on the top side of the board.

Hello,
This unit came into the shop late today. Appears to be
going into high voltage shutdown, powers up (green
LED) for about 5 seconds then Yellow LED flashes. I
havent been able to measure the H/V even though I hear
it building up.
Will tear it down further tomorrow to inspect
regulator FBT circuits. Does anyone have case history
info on this model?
Item specs: SONY MONITOR MDL: CPD-20FS2 FCC ID#:
AK8GDM20F03
Thanks Much
