Assuming this is Sams 1370, take a look at C270 10uf 300v on the 240v boost supply from the Horiz Out Transformer. That boost source feeds the RGB Video outputs.

Did I understand correctly the "jail bars" are intermittant?
No, they aren't intermittent. They are always there, but can be reduced by bring down brightness and contrast to an unusable level.

Posting a pic from the DVD player screensaver.

I have a new 10uf 300V capacitor on hand as I want to replace them all again to ensure I have the correct replacements installed. I replaced them 13 years ago, but I didn't have the SM, so I ordered solely based on value. This time I used the part numbers from the SM and got all but one based on that info. The other one is supposed to be 25uf 15V non-polar, but the SM has no part number and all I could find was a 22uf in non-polar.
