What is the value on resistor RK 62 and RK 63 for the 57F500A

yes the 2 watt resistor is actually better than the 1 watt. They will both work in place of each other. The important part are the ohms they have to be exactly the same.

Alot of techs recommend using the higher wattage ICs to replace the stock ones, which is never a good idea since the resistors get stressed. Upgrading to the STK394-160 IC is the only upgrade Hitachi recommends but then the values of the resistors need to be changed since the stock resistors will not work with the upgraded ICs

I know it's an old post but the parts is a 5amp current inrush limiting thermistor with 10 ohm value at nominal temp

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.


SD TECH

rk46 is 1.8 ohms and rk 50 is 2.7 ohms.

The value of RK99 is 3.3 ohms, 5% and 1/2 watt.

Hello,

Check what is happening when you press flash focus?It completes 1 full cycle or not?
If not complete 1 full cycle check small value resistors on convergence board.All RK series resisitors..

Dont Forget to Rate!

Good Luck

Yep its ok. No change in resistors is necessary.

Can anyone give me the resistor values for location RK 42, RK 46 and RK 62? Hitachi 46F500 TV. Or can I be pointed to the location of a service manual?

RK42 = 2.2 , RK46 = 1.5 , RK58 = 3.3 , RK52 = 1.8 , RK 50 = 2.2 , RK54 = 1.5
