[TechAssist] Re: Sanyo DS27930 - Dead, FIXED

Original Problem:
Sanyo DS27930  Dead set

Repair included:
Vertical IC  IC501 LA7849
H.Out. Q402  2SD2645
R463 - 3.3 ohm, 2 w
R483 - 1 ohm, 1/2 w
D501 - 75 v. zener
D483 - subbed 1N4936
C487  1000 uf / 35 v.

This enabled TV to power on, but had sides bowed in and IC501 would run very
hot.

Replaced D461 - subbed with 1N4936

TV now works good again.

> Hello,
> I need the value of Zener Diode D502.  It is located in the vertical
circuit off pin 2 of IC501 (LA7849).  No print and writing on diode is so
small, can't make it out.

> Please note - this circuit is different from the circuit in the DS27910
schematic.
