[TechAssist] Re: Zenith Model # B25AO2Z Module 9-2143 Shuts Down

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.
Jeff

> Hello Gang. 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.
