RK46 BURNT CANNOT SEE COLORS ONLY 2 STRIPS DARK AND 2 STRIPS LIGHT. WHAT IS THE OHM VALUE AND DO I INSTAL GOLD STRIPS TOWARDS IC OR AWAY. HATACHI 43FWX20B DP24 JOE


rk46 is 1.8 ohm resistor---rk54 is the same value, rk 62 is 2.2, and Rk 42 is 3.3 ohm. It does not matter which direction it is installed---it is a resistor


If you have any questions feel free to let me know.

1.5 ohm resistor rk 46 keeps blowing


You should have put the original OEM STK's in the set - if your set had 110's or 120s put those chips only. Do not risk different chips with different specs/amps/ etc....when you do resistors blow as you have discovered.

RK46 Changed - Still have clicking diode then the board dies.


I would check the standby voltages and see if they are correct and then move on from there. The flyback will usually have signs of heat around them, however that model really isnt famous for trouble some flybacks. I would check the supply voltages for sure that could give you a better leg to stand on as far as determining if a repair tech should be called in or not
