Question about Hitachi 53UDX10B 53" Rear Projection Television

Resistor ohm values??????

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

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.)

If the problem is exactly like before one of the protect resistors is bad.

The color bands denote value in resistance and usually it will be a 1.2, 1.5 or 2.2 ohm resistor. You check them with a ohm meter, like checking a fuse--any that has no reading across it is gone.

Usually they will be discolored but sometimes they open so fast they do NOT discolor.

There are only about twelve of them and many are higher values--150 ohms or more==always it is a low value resistor that opens--it is what it is there for--a chip shorts in some way and the resistor opens to protect the power supply that feeds it.

Looking is not always enough, you have to check them. If this is helpful a rating would be appreciated as I do this here for free.

I am available to assist you if you need it.

Hitiachi Convergence Circuit Resistor Values

This site has been very helpful in diagnosing and repairing my Hitachi 57XWX20B. I recently changed the IC's and a resistor to fixe a convergence problem and had to use the small button on the convergence circuit to get set to return from static mode and enter dynamic mode. I searched everywhere trying to locate the correct resistor values and noticed many other's needing the same information. Here are the results of my research. I obtained some from manuals and others from comparison of the different models. My main focus was finding the values for the 57XWX20B. The resistor values are given in ohms at 1 watt. This means RK42 is a 3.3 OHM 1 watt resistor. RK58 was the problem in my set. It was giving a value of 2.3 and needed to be 4.7. I first replaced the IC's and thought the resistors were all good, but I later noticed my convergence was off. I could manually align it but the magic focus initiation would not save. It gave an overflow error. I bought the sanyo brand of IC's, not the cheap inports and found that if you use a desoldering wick then the repair is easy. The new IC's restored the beautiful color the set had when new. Now it is brilliant as well as converged. My repair cost was:
STK-110 13.00 Bought from local electronic supplier
STK-150 15.00
RK58 3.00 Bought from a local TV repair shop

The elecronic supply store gave me 6 inches of desouldering wick
Total cost: 31.00 Dollars

I have a hitachi 43FDX15B RPTV It appears to have a convergence problem, I've read about replacing the stk IC's but which resistors need to be replaced and what are the values on the DP15k/08 Board?

This model uses two of the STK-392-120 CHIPS and here are most of the usual resistors to suspect or check:

Hitachi AT03411S RK43 RESISTOR Hitachi AT03608S RP22 RESISTOR Hitachi AT03195S RK46,RK54, RK62 RESISTOR, 1.8OHM 1W Hitachi AT03857M R815,R865 RESISTOR, 1/2W 100 OHM Hitachi AT03191S RK50 RESISTOR, 1W 1.2 OHM Hitachi AT03197S RK50 RESISTOR, 1W 2.2 OHM Hitachi AT03199S RK41 RESISTOR, 2.7 OHM 1W Hitachi AT03202S RK42 RESISTOR, 3.3OHM 1W Hitachi AT03204S RK58 RESISTOR, 3.9 OHM 1 WATTThe RK ones are all marked on top and bottom of circuit board---usually if one is bad you will be able to see it is discolored---all are very low value and should read open or good only.

This is a fairly easy set to do this on---the whole convergence board (right side from the back view) is held in with 3 screws and an assortment of plugs--3 plugs are identical (convergence yokes and you need to mark so you get each back in same place)

A row of black snap plugs on the left side and with the screws and other plugs removed the board will lift up and out of the set.

DON'T waste your money on one of the "kits" being sold on the net---you can buy a pair of the chips for about 12 dollars on Ebay and usually only one (if any) of the resistors will be bad---those kits sound like a good idea but at 50-80 you are buying things you will not likely need to repair the set.

Let me know if you have any questions and if this information helped you rate this solution as I do this here for free.

Zenith R60v26 has burnt resistor at RK5 on convergence board

Hello, I have the exact same issue with my R49W36, I replaced the convergence chips but there are also two 1 ohm resistors with the same color pattern as yours that are bad. I have looked all over and cannot find a 1 ohm resistor anywhere. Where did you find it?

Color convergence still busted

2.2 ohms/1 watt if you have chassis number AP74.
3.3 ohms/1 watt if yo uhave chassis number AP73.
