Question about Hitachi 65TWX20B 65" Rear Projection Television

1 Answer

I have recently receive a convergence kit from www.tvrepairkits.com for a Hitachi 65TWX20B DP27D. While inspecting the convergence resistors on the convergence board I noticed that RK50 was discolored. I want to replace this resistor but I do not know what the resistor value is. I looked through the Hitachi service manual (No. 0160, Ver. 0160.08) and on the convergence Basic Circuit Diagram it lists RK50 as being 3.3 Ohms, but on the Parts Breakdown list it lists RK50 as being 2.7 ohms. Which is correct?

Magic focus does not work. RGB projections do not line up.


That symptom is usually caused when the convergence ICs and associated resistors fail. You can get convergence repair kits for the various Hitachi models from www.tvrepairworld.com the kids contains both ICs and the associated resistors plus the CD with repair instructions.

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

Color will not match up


if your talking about the sets convergence does not line up and it looks like a 3-D picture than The best advice I can tell you at this point is to go to tvrepairkits.com and order the complete convergence kit for your model of TV set, no need to search and order multiple parts from different sources and pay multiple shipping fees! Go to http://www.tvrepairkits.com/xcart/home.php?partner=larry
The kit comes with original Sanyo STK IC'S , not those cheap aftermarket or china made IC'S full pictorial directions, the thermal paste, resistors, the correct Pico fuses, AND free live on-Line tech assistance in case you run into a problem with the repair. They ship out 2 to 3 day Priority mail, the next day in most cases GOOD LUCK!!!

Hitachi Model# 43FDX01B is doing a double image.


You have a convergence problem, you will need to change the convergence IC's STK392-110, there is also 12 6.8 1w resistors that need to be changed, there is also 2 fusilbe resistors that may be open. You can probably Google the IC's as a kit and find them all in one kit.
You can fix this yourself and save about $300-$400 in repair bills.

Need service manuel free download site or codes for circuit board to reset to manufacture settings if possible on convergence problem


You can get a free manual if you buy a kit from www.TvRepairKits.com . They will typicaly email one to you if you just ask.

Here are some of the most common symptoms and example photos of a convergence problem



  • Screen looks 3D
  • Colors don't line up
  • One or more colors can't be adjusted when using the convergence menu.
  • Screen is bowed or warped.
Here are some photos of convergence problems.

Here is a quick test....

Using your original remote go-to the tv settings then goto the convergence section.

Try to adjust the red and then the blue convergence.

You should be able to move them up, down, left, and right.

If you can't move them in all directions your convergence chips are bad and should be replaced. This is a common problem.

You will need to replace the convergence chips and possibly some convergence resistors and pico fuses. Its a fairly easy DIY job or you can call in a pro. If you want to do the repair yourself check the site www.TvRepairKits.com. Their kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, thermal paste, email/phone support, etc.
