Make : Zenith
Model : PVR5263RK w/9-1302 sweep/smps & 9-1527 signal bd

Problem : Dark Smeary Video...red seems most predominant.  Customer says
problem may be OK for a few minutes...then it fails. We have not seen it
working OK

All of the 120K resistors have been changed on the CRT drive boards &
connectors resoldered also on the CRT drive by another shop.

Right now I'm changing R3243 & 3244...they do check OK though....they are
the original parts.

R3267 looks a little crispy...can someone confirm it's value? (3.3ohm?)

Any other common areas on this set we should be checking for this type of
failure?
