Yes - But Ddent will not provide any instructions or support with your repair. If you need that goto sites such as www.TVRepairKits.com instead.
This is a very common failure on these projection sets and a fairly simple DIY fix. All projection sets including Samsung, RCA, Sony, Philip Magnavox, Panasonic, Pioneer, Akai, GE, JVC, Toshiba, and others at some point will have the same problem.

Common Symptoms include....


  • 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.
  • TV shuts off after powering on. Power light will blink. TV may also make a chirping noise.
Here are some pics of convergence problems.

Common 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.

In this repair kit, which RK##'s are they supplying you to replace? they list the ohms but not which ones they expect you to replace. (there are 13 total on the board..)

It is the stk 392-110 ic chips. You need to repalce both of them along with a resistor. I believe it is the RK 54 1/2 watt-1-ohm.

Ur tv have a problem call convergence problems.The tv convergence board,require changing 2 STK convergencve ICS and some or all it resistors to solved the convergence problems.U know how to solders?Have soldering tools and solders?Tries websites like Tvrepairworld.com,Tvrepairkits.com to buy a convergence kit to repair it ur self.The shop will cost u $300-350 for parts and labors.

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.

Try adjusting the convergence. If it won't move see below- (or hitting Magic Focus for some Hitachi’s)

This sounds like convergence output IC problem. convergence board would have to be removed - remove and replace 2 STK IC's and check the surrounding resistors. Shops usually $200-$400 Be sure to vote/rate me if this helped Thanks!

Re: 43FDX01B blue convergence issues


Ditto CTF1800's comment....Check RP-41 1.5 ohm 2 watt and
other low value resistors near IC's mounted on large heatsinks.

STK392-110 original convergence IC's can be upgraded to
Hitachi # CZ 01341 new number STK394-160E for greater reliability.......Hitachi also has an IC / resistor kit # X480295,
but I don't change good resistors, only the bad one(s).

Practice good visual acuity technique and ask questions!.....T.
