43FDX20B RK58 RK50 RK54 RK42 Values STK392-120's

The following resistors need to be replaced but I'm uncertain what the values are supposed to be. RK58, RK50, RK54 and RK42, I'm also going to replace the 2 STK392-120's. Thank you I have repaired a convergence issue with a similar Hitachi rear projection tv, but I need to make sure I have the appropriate values for this convergence board. Thank you

    Also the Wattage values would be appreciated, I was thinking 1W for them ?? They are fire resist

  • Christopher Ripley May 23, 2012

    I now have the service manual and currently deciding whether to install the newer upgraded resistor values or the original values from the service manual. Because the manual is an updated copy it has the update with the original scratched out, but you can still read the value so I'm not certain whether or not to use the updated resistor list and install all new resistors to match the new schematic or go with the original scratched out values. I read a post of someone finding this controversial in that you will have to do another service mode re-alignment for the convergence; but wouldn't you do that anyways when replacing the IC's and few resistors ? Updated values or not ?

    Thanks, I think I'm just answering my own questions lol

    So if anybody wonders what the values actually are, here are the updated resistors for CONVERGENCE DP15K/DP15J/DP15H:

    43FDXX15B, 43FDX20B

    RK42 = 3.3 OHM 1 WATT
    RK46 = 1.5 OHM 1 WATT
    RK50 = 2.7 OHM 1 WATT
    RK54 = 1.5 OHM 1 WATT
    RK58 = 4.7 OHM 1 WATT
    RK62 = 2.2 OHM 1 WATT


    53FDX20B, 53SDX20B, 53SDX20BB

    RK42 = 3.9 OHM 1 WATT
    RK46 = 1.5 OHM 1 WATT
    RK50 = 2.7 OHM 1 WATT
    RK54 = 1.2 OHM 1 WATT
    RK58 = 4.7 OHM 1 WATT
    RK62 = 1.8 OHM 1 WATT

    These are all metal oxide fire proof resistors.

    Hope that helps someone else down the road.

    Sorry for the typing error on the tv model numbers, the first set should say
    43FDX15B and 43FDX20B :P

I don't think it will hurt especially if the updated manual indicates it.

    Yes, I agree, I have decided to upgrade all the upgraded resistors as a complete set, they have probably upgraded the values for a longer life expectancy for the convergence board.

    Thanks

If your tv is a 43uwx10b the original values of the resister are correct it is a DP14G chassis do not change the values

SOURCE: i need the resistor values for RK42, RK46, RK50,

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.)

SOURCE: Hitachi 43uwx10b. How do i test resistors for

You have all the resistor are correct! Yes I can Tell you exactly what you need to know and How to Save settings after you adjust convergence, I have to pull out my manual on your hand unit Be right back. first you need to go to front of TV remove front bottom panel to where you can see the front of chassis on the board you replaced ICs there is a small blue contact button with TV on press and hold for 5secs Convergence Pattern should appear! You will need your hand unit to begin to adjust convergences.

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.

ok
upgard the stk392-110 to a stk392-150
note use flame proof resistors 1W
rk42=3.3ohm/rk46=1.8ohm/rk50=2.7ohm/rk54=1.5ohm/rk58=3.9ohm/rk62=2.2ohm

Replace Both of your STK ICs convergence ICs STK392-110 use 150s Better ICs Call Mats 1-800-628-1118 Also RK42 RK46 RK48 RK50 RK54 RK58 RK60 will have to get back to you on resistor values
