The problem was the same as I just read. looks 3D cannot align colors.


Thats a common problem caused by failed convergence ICs and possibly their associated resistors may need replacement. Your model is the DP14G chassis you can get the DP14G convergence repair kit from www.tvrepairworld.com which has the instructions included.

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.

Good Day,

Sounds like the TV's convergence circuit has failed:
*Call an Authorized Service Center and them give you an estimate cost of the repair, or
*Repair it your self; get KIT 10 locally or B&D Enterprises

Good luck, big IRISH.

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

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.
