Thanks to ED from teltek on the scan of the regulator ckt on this set.Had gone tru a power surge.Replaced the reg STR-Z4214,F860 =4a pico fuse,and D825=12v zener. Now I have a different problem.Picture is fine on the higher ch but the low ch,there is a floating bar that goes up the screen and as it does,the pix has some vert. jitter.I subbed the tuner but still the same.I checked all lytics in the ps,reg.ckt and all are ok.The pix is ok when using an external source via the audio\video jacks.Must be a ripple in the vcc line to tuner.Does anyone have any tips for this problem.Thanks.
