Your symptom sounds like at least one damaged convergence IC.


You are correct you can sometimes rework the solder connections on each of these IC’s, although, if the convergence does not fix itself from time to time, you most likely do not have a bad solder connection. You will have a faulty IC. I recommend to replace them both at the same time because the chips legs can fall off due to the heat of the IC.

Please be sure to remove all of the white heat sink compound on the heat sink and apply a even coating over the back of the new IC’s. You should also bolt them down before you solder them in so that you have them at the correct height.

There are two and sometimes three very large IC’s that control the convergence in a big screen set. I believe that your set has two. They are secured to a very large aluminum heat sink. I think that the IC numbers will be IC8001, 80002.


The IC’s are large and black, you cannot miss them. They will usually have an STKXXX-XXX number on them.


There are several schools of thought on the replacement of parts and I firmly believe that you get what you pay for, so don’t buy the cheapest IC’s that you can find. One company I worked for tried this and it only caused more work for the technicians, as we had to replace them with the more expensive ones in the end. I would think that you should be able to find these for around $60.00 each. If you can find the exact Hitachi part, or Sanyo, even though the numbers on the front are the same, and they look exactly like the $10,00 ones, they are better and more reliable.

I usually order my parts from Andrews Electronics in California, they will have the OEM components that you will need.
Their site is http://www.andrewselectronics.com/welcome.aspx
And their phone number is a 24-Hour Order Desk: (800) 274-4666
I recommend the phone order so you can talk to the person about the different types of IC’s that are available.

You can also try http://www.tvrepairkits.com/ , I have not tried them yet, but they do carry OEM or better parts.

I hope this information allows you to resolve this issue.

    They should be on the IC's them selves in large white numbers.

Why does my hitachi rear projection tv has double image?


Are the double images different colors, such as red or blue or green? If so, the projection unit is "out of convergence, meaning the images are not superimposed on one another. That requires a convergence generator, also known as a video alignment generator.

Blue haze around images.


It sounds like your drive jets are out of alignment. Ask your local TV repair places what they charge for re-alignments.

Red and green snow near the sides of the screen


As in there's blotches of red and green at the edges, but the image is still there?
If so, then your screen may have come into contact with magnets, or maybe the alignments are off (TVs align overlapping images in red, green, and blue).
As always, check with the manufacturer support lines, as they would have specific information for these kinds of scenarios.

Rcs hdtv multiple images


The problem you're having is due to the failure of the convergence amplifier circuit. In that circuit are some components which amplify or control the signals to the dynamic convergence yokes, which line up the red green and blue images to superimpose them over each other to create a proper colour picture. When you get a failure in that circuit, it no longer aligns the images properly, and generally you get what appears to be badly set geometry in multiple colours. In some cases you will also get a problem with the part of the power supply that supplies the convergence amplifiers, or the digicon, which is the digital convergence control module.

Hitachi 53UWX10BA HDTV with convergence problem for blue


No there are no quick fix options for this fault. The convergence amplifiers operate similar to a high power audio amplifier, so if there is an impairment anywhere in the system, it will result in distorted audio, or in the case of television convergence amplifiers, a color won't align. The convergence power pacs need to be replaced and the out of tolerance precision resistors located near the power pacs need to be carefully checked and replaced as necessary.

It is also possible that there are root faults that cause the amplifiers to go bad which include bad connections or a bad digital control module. This repair is possible for anyone having basic electronics knowledge and soldering skills.

Double image/ out of focus with green and blue seperation


Your tv is crt-based and is out of convergence. In other words, the settings for keeping the Red, Green and Blue images aligned have drifted and must be reset. This is common with CRT projectors and CRT rear projection tvs.

Refer to your owners manual for instructions on re-aligning it.
