This was a quite good set. A case of a mid priced set that came
out as good as a premium brand. In other words someone
screwed up !!
IIRC these had a PLL chip that would go bad & Z0064 HV
rectifier / divider that cracked open. Dont give up on it, post
a picture & we can figure it out. Also chassis pic & model ##.
They are easy to work on.
