Question about Hitachi 43FDX01B TV

1 Answer

I changed my two IC chips and three resistances on my Hitachi TV to fix color alignments. Now the problems is that yellow and blue double image are seen at the bottom of my screen with no much effect on the rest of screen. Manual convergence show a white horizontal and vertical lines with focal right horizontal end with red line no aligned, but if I fix this side, the left side is disaligned. So, I am lost. What can I do?, what is wrong?

Ur tv still have dead resistors parts,test all 12 resistors parts around the 2 STK convergence ICS and changes some more dead resistors parts or changes all 12 resistors parts for sure.If tv still have the same problems after tested and replaces more resistors parts or all 12 resistors parts.Than some how when u handling and replacing the 2 STK convergence ICS and resoldering the 2 STK covergence ICS u short it out the 2 STK convergence ICS by resoldering without proper grounding ur self not to allow for static electricity to kill the 2 STK convergence ICS or u using a soldering iron to high of a wattage for doing soldering ICS work.

I 53" Hitachi Projection TV and I get double


All projection TV sets have two very common problems. One is convergence ( 3D/Warped video) the other is CRT fluid ( Dull Video). Here are more details and solutions for both.

Common Problem #1) Convergence has gone out

Projection TV sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the video to look normal. When its out of alignment the video will look 3D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the TV menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired.

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.

The colors are all there but there is a double image. Like a blue or yellow outline around everything and words are doubled. I think it is a convergence problem but I don't know how to fix. Please help.


It is convergence problem---set uses either 2 or 3 chips for this (most use two of the STK-392-110 OR 150 CHIPS.

Total parts cost on EBAY would be under 25 dollars.

This can be a do it yourself job if you can solder and have some skill.

See attached photo of convergence problem and typical convergence IC.

I have some distored blue color across the screen


Projection sets have two very common problems.

The first common problem is convergence


These sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the picture to look normal. This is called convergence.

When its out of alignment the video will look 3-D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired. Convergence problems are very common on all Projection TV sets including Sony, Samsung,JVC,Philip Magnavox,Panasonic,Akai,Pioneer, Hitachi,Mitsubishi,Zenith and others.
You can get more information and a DIY convergenece repair kit with instructions from the link below.

Here are some of the most common problems with these sets...

*Screen Looks 3-D
*Colors wont align
*Screen may look distorted or warped
*No Audio/Video - TV Shuts down - May also make a constant chirping sound

Problem #2 - Another common problem is dull or washed out video.

Your set may have one or more of the following symptoms....

*Dull looking picture
*White looking picture
*Halos around objects
*Red/Orange looking picture

Hi,it seems you are experimenting a light engine problem.This is how your tv works: http://www.youtube.com/watch?v=ZLLHnQ4y-wo So basically the 3 Lcd chips that create the colors and image is going bad and thats why you get that color discoloration.Contact Hitachi or look for your light engine online.God bless you and your house!

Color is mostly yellow and blue with double images


you have lost the convergence IC`s in your set, this really isn`t a diy repair unless you are very proficient in un-soldering and re-soldering components, once replaced there will be an alignment procedure as well that will require the service manual also, if you have more questions feel free to ask away, video-tek

Double Color images and Convergence will not adjustment will not line up


The convergence IC`s board location are IK 04 & IK 05. Looking from the back of the TV they are mounted to a large finned aluminum heat sink on the right side of the chassis. The origional part (stk 392-110) can be substituted with an equivalent but higher powered IC (stk 392-180) , that is 180 watt instead of 110 watt chip. Do not use generic IC`s! Purchase origonal Sanyo chips only for best results. Replacement of the chips alone may not cure your problem if there are dammaged resistors caused by the origonal chips. Check the standing resistors on the opposite side of the heat sinks for proper value. RK42(2.2), RK46(1.5), RK58(3.3), RK52(1.8), RK50(2.2), RK54(1.5). All of these low ohm resistors are rated at 1 watt. If you encounter a bad resistor you must replace with the same exact value. Close is not good enough. This should fix your set. Do not buy a policy you have a good TV. Be sure to use a liberal dose of heat sink compound when insatlling the new chips, and clean off the old crusty stuff.

Solution:
Your TV has a convergence problem. Here are some of the most common symptoms.

Screen looks 3D
One or more colors can't be adjusted when using the convergence menu.
Screen is bowed in but stationary.
Here is a quick test....
Using your original remote go-to the tv settings then goto the convergence or magic focus 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 can get a repair kit that includes all the parts from www.TvRepairKits.com.
They have put together a kit for the Hitachi TV sets.
The kit includes a photo instruction guide, original Sanyo STK chips, convergence resistors, etc.
Everything you need to fix it yourself. Its a fairly easy fix on the Hitachi sets.
