Fist off I am a newbie who has an out of convergence Hitachi . After lots of reading I found out I had convergence issues so I ordered 2 STK392-150 (I read it is an upgrade from the STK392-110) but I am unsure about the ohm values for resistors RK42, Rk46, RK62, RK58, RK54 and RK50. Does anyone have schematics for my TV or know the values? Thanks
RK42 = 2.2 , RK46 = 1.5 , RK58 = 3.3 , RK52 = 1.8 , RK 50 = 2.2 , RK54 = 1.5

You are right, I hit the wrong key (5 instead of 6). RK62 is 1.8 ohms. RK42 is the red horizontal channel, RK46 is red vertical, RK58 is green horizontal, RK62 is green vertical, RK50 is blue horizontal and RK54 is blue vertical.
Always use the STK392-150 in place of the -110. It is the improved, stronger version. The resistor values I posted come right from the schematic, so I am not sure why they sent those values in the kit. If the original resistors look fine, and none of them has burned up, I always leave the original in there. They only go bad when an IC shorts out, so there is no need to replace them if they are good.
I have an account with Hitachi and I have access to all of their service manuals. According to the service manual posted by Hitachi, the resistor values for the 53UDX10B are the ones I originally posted, which should be the values of the original resistors in your set. I did some more research at the Hitachi website and found the service bulletin describing the convergence output IC kit. It states that for the 53UDX10B and the 61UDX10B, the values have changed to the values you have listed. Since the STK392-150 functions exactly like the -110, if you change the values of the resistors you will have to do a complete realignment of the convergence in the service mode. Personally, I replace both STK outputs but leave the resistors alone, since the digital convergence is aligned with those resistors.

Rk 54 resistor value for an hitachi 43FDX01B

SOURCE: 65xwx20b
i need value for RK62, resistor burnt and cant see colors. on DP2X board 57SWX20B near the green STK connector.

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.)

Thanks but did you give me RK52 instead of RK62?
Hey thanks. The kit I ordered comes with the following resistors 1.5,1.8,2.2,2.7,3.3, and 3.9 so I guess I will need to order some more? Also is it ok to use the STK392-150?
I got an email back from the place I ordered the kit from. Here is a copy of it.
For model# 53UDX10B,
To the best of our knowledge here are the resistor values.
RK42 3.3 ohm
RK46 1.8 ohm
RK58 3.9 ohm
RK62 2.2 ohm
RK50 3.3 ohm
RK54 1.8 ohm
It seems this model has 2, 3.3 ohm resistors & 2, 1,8 ohm resistors.
Again, this is to the best of our knowledge.
So I guess they must be wrong????????
It looks like RK54,RK50, and RK58 are burned up but I have not tested them yet.
Thanks so much for your help. RK54, Rk50, and RK58 were burned out and showed no value with the multimeter so I had no choice but to change them out. After testing the remaining three and finding values similar to those provided by the repair kit supplier I went ahead and changed them out as follows: RK54 1.5 ohms, RK50 2.7 ohms, and RK58 3.9 Ohms. It took me about and hour to manually adjust the convergence, (probably since it was my first time ever to try it) but it was well worth it. The picture is better than I can remember.
I'm an idiot..but with your help I can do the fix...thanks!!!!!!!! but 1 more idoitic question....what is the watts on the resistors? are the 1/2 or 1....my guess is 1/2...but we all know what guessing brings lol.....
thanks again for your knowledge!!!!!!!!!!!
