Subject: [TechAssist] Magnavox RR2540A101: Dead
> This set came in dead. Found R407 open and C431 with high ESR. After
> replacement still no power up. R433 appeared to be open in circuit so I
> pulled to check out of circuit and as I was checking it my probe slipped
and
> the resistor went flying never to be seen again. Could someone tell me the
> value of R433? Also any tips, a schematic or model cross reference are
> appreciated.
