Grady, Vertical IC can cause this..check your voltages. I believe this one uses -13 and +13v's Also, Q3401(121-1264-02)could be shorted or leaky, if so-replace *R3406(47 OHM)*D3410(NTE588)* STR53041 Let us know how you make out.

Hope everyone had nice Christmas. > This Zenith CA Chassis came in DOA. Mfg. in Oct 2000. This module looks like new. No cracks, bad traces,or discoloration found. Fuses good. I checked CX3407, RX3404,ICX3400[SRT53041], resoldered drive trans. I monitered the HV and when it reach about 28KV it shuts down in about two sec. I've never worked on this model and I have no schematic. Any help would be appreciated. > Happy New Year----Grady > GOW TV Serve > > ------------------------------------------ > Help make your TechAssist database better! > Submit your fixes here: http://circuitwork.com/techassist/tip/#tips > ------------------------------------------ > To UNSUBSCRIBE your email address, click here: > mailto:techassist-request@xxxxxxxxxxxxx?subject=unsubscribe > Or send a BLANK email with unsubscribe in the > SUBJECT field to the address above. > > ------------------------------------------ Help make your TechAssist database better!
