Jason, I don't know how similar these chassis may be but you may want to
check or
change the IC described below if your set has it. It is an RF, Audio/Video,
input switching IC.
Jamie
Replacing QV01 fixed the set.
QV01 is a 42pin ic (MM1495XD) PN 23000369
Thanks for the replies and especially to Bob Waterman for uploading the
service manual and schematic.

sync
> This tv was struck by lightning, evident because it originally wouldn't
come on. I found a shorted transistor in the relay circuit. Now that the set
comes on it seems to operate normally accept there is no horizontal sync or
even vertical sync. It does tune and has good audio. It looks like the RCA
ctc177 when the horizontal phase is missadjusted. I don't have a diagram and
haven't scene one of these chassis yet. Being it has 2 separate problems I
believe it was lightning and am wondering if the eeprom in these are
anything like the CTC177. Can these be adjusted or must I change the eeprom.
If anyone thinks it is not likely the eeprom let me know. I may have to get
a diagram on this one.
