Look for the model number (43fdx01B etc) and from description I suspect maybe the convergence chips----confirm to me actual model number and I can tell you how to proceed.

SOURCE: the Screen looks 3D & Colors don't line up on my big screen????

If the convergence is off more than 1/2 inch or so you can't adjust. you have a failure of hardware. most likely the output IC. This set has 2 outputs for convergence. Each output contains 3 circuits, Six circuits altogether 2 red ,2 blue and 2 green. The normal customer adjustment will only alow adjustment of blue and red. They should be converged onto the green. There is a much more complex adjustment in the service mode for Geometry and convergence. These adjustments are only needed when you replace a failed componnent like the output ic. These ICs have been upgraded several times since the production of this set. The latest and most powerfull version is STK394-160. If feel up to it I suggest changing both outputs and the corresponding output resistors. Then do a complete geometry and convergence alignment.

There is most likely a problem with the lamp or lamp driver. You would think the television would have a way or telling you though.

SOURCE: hitachi 51f500a rear projection tv screen looks 3d

This model uses two convergence IC's----if 3 D one or both are bad.


Most of the time this set uses either two of the STK-392-110 OR THE STK-392-150 CHIPS.

Both chips and any bad protection resistors around them need to be replaced and the set adjusted.

If you are able to do the repair yourself total parts cost will be under 30 dollars.

Some history for you:
This set like all rear projection tube type sets uses two chips---the ones in your set are Black in color--about 2 1/2 inches wide X 1 1/2 inches tall and are on either one large or two smaller heat sinks with fins on them.

When the chips are installed a white grease called heat sink compound is applied to the metal back of each---the grease transfers heat from the chip quickly to the metal it is bolted to.

After some years the grease dries out from the heat and one of the chips goes instantly.

You can buy a pair of the chips for your set on Ebay for less than 15 dollars plus shipping--

If you cannot do the repair yourself--shop around your area---most shops charge 300-400 for this type of repair. Whoever you get to do it make sure BOTH chips are replaced or you will have the same problem in a few months.

If you open the set and locate the chips---they will have the full STK number printed on them in white letters----there are about 12 resistors around them that need to be looked at--if any are discolored they need to be replaced.

If a shop says it HAS TO GO TO THE SHOP keep looking as any good tech can do this repair right in your home in about 1 hour---I know as I have done hundreds of them.

IF you can solder and are handy I will give you general instructions on how to do the repair and what you need---some people I talk to can either do it or have a friend who can do it for them---let me know

I can tell you what you will need aside from the parts and how to proceed with the fix---

If all this helped rate this solution---I do this here for free.

IF YOU HAVE ANY QUESTIONS OR NEED ADVICE LET ME KNOW--I am here to help people.

Regards, SD TECH

Screen is scrambled. Working fine until I unpluged the TV one day. Is it a fuse?


If it looks 3d or warped its a convergence problem

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 images of convergence problems.

51 inch projection- can't read words clearly,


ll 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.

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.

Picture of a set that needs the fluid changed.

42" Rear Projection color issue


Projection TV sets are known to have two common problems. The first problem that is common to these sets is convergence failure. When this happens the TV will usually look 3D, Wavy/Distorted, etc. It may also shutdown and blink an error code.

The second common problem with Projection TV sets is dull video, halos around objects, white looking video, or red overpowers the screen. This is commonly caused by the fluid in the lens being clouded overs.

No Picture No Sound


were the colors looking 3D before the set shut down? If so chances are its the convergence amp ICs and thats what has shut your set down. Let me know if you need anymore info.
