working on a couple WG4900's.

stuck on this one.

put on a full cap kit. subbed out IC301. and reflowed a bunch of solder.

but it still has a high pitched squeal when the synk is hooked up.
and i cannot get the H-Hold to correct its self.

it has a full screen and you can tell that the image is synked and the H-Hold pot works as it will correct the skewed image. but the image is still not even close to being visible for any type of play.

the only way that the squeal stops is when you unhook the synk. but the pic is still all wonkey and unusable.

what am i missing. i did a search and could not find an answer.
maby its a resister out of tolerance but if it is witch would it bee.

if what i am trying to describe is not accurate i can get a video of what its doing and post it. as a pic will only show it needing a H-Hold adjustment and that is not what it appears to be.

any help on what to check would be great.
