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.

Subject: [TechAssist] Sanyo DS27930 need zener diode value
> 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.
