1)Replacement requires skilled soldering technique.

2)The IC's are on the largest heatsink on the chassis.

   Chassis will need to come out==skill and/or experience needed.

3) Possible bad fuse device in power supply,check any/all.

4) Re-check alignment.

 

PS.Name brand IC's last longer than generics.

My hitachi model 43uwx10b has magic focas problem's red,green,blue and yellow are moon shaped across the screen


The two STK CONVERGENCE CHIPS AND ANY BAD RESISTORS AROUND THEM WOULD HAVE TO BE REPLACED.

Typical cost for all the parts on EBAY or Suburban Electronics would be under $25.

Manual Convergence adjustment on Hitachi 43UWX10B


I would guess you missed a open resistor--there are only about 12 of them--how did you check them?

This set (43uwx10b) has a tiny blue micro switch on the front of the chassis---if you engage it from the front the set will go into the DECAM or convergence mode--let me know the CLU number on your original remote and I will scan and paste instructions---98% of the time if the set is wacked out and will not adjust one of the resistors is gone---ONE OF THE CHIPS GETS THEM.

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.

You need to replace the convergence chips and convergence resistors. Check the site www.TvRepairKits.com. They have put together a kits for most models. If you don't see a kit for your set send them a quick note and they will put one together for you. Their kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, etc.


Problem #2 CRT Fluid is Cloudy

Projection TV tubes have a liquid coolant that is used to keep them from overheating. After many years the coolant in the blue and green tubes will become cloudy and cause the screen to look dull, red/orange, etc. You may even see halos around images.

Picture of a set that needs the fluid changed.

What you will need to do is replace the coolant and clean the crt. You can get a repair kit from www.TvRepairKits.com that includes replacement coolant, photos. instructions, etc.

43UWX10B problem with green


if you have a 2 IC convergence chassis they dont control the green , However if you have the 3 IC chassis the green is controlleed by the third IC these are usually STK4275 or simallar single amp ICs. Which type chassis does your hitachi have? Its possibly related to the digital convergence board if all resistor near the ICs are good. Do you have the service manual? I can post a link where you can get the full service manual if you need one
