I need the resistor values for RK42, RK46, RK50, RK54, RK58, RK62 when using stk392-120 chips in Hitachi 53UWX10BA.


If it is 53uwx10B:

RK42 2.2 OHM 1 WATT
RK46 1.5 OHM 1 WATT
RK50 2.2 OHM 1 WATT
RK54 1.5 OHM 1 WATT
RK58 2.7 OHM 1 WATT
RK62 1.8 OHM 1 WATT


Double check the numbers on the STK chips as most of these sets use STK-392-110 OR 392-150 CHIPS-----ONLY A FEW OTHER MODELS(MOST 43 INCH USE THE 120 CHIP.)


I do this here for free so if this helps you take just a minute and give me a vote here.

Incorrect resistors on DP1X PWB?


Assuming this unit was never worked on and it was actually working properly before the IC's decided to take a vacation I would recommend leaving them alone as there may have been an engineering change after the service manual was printed.
