Question about Hitachi 53FDX01B 53" Rear Projection Television

Color ghosting I have a convergence problem .I brought the set in to have it repaired and the tech could not fix it . In the begining I was unable to do a manual convergence with the remote from the TV. The Tech told me it was in the IC on the guns. He was able to get the colors to converge but was unable to get a clear picture without the ghosting . I'm in the process to take it to a liscened "Hitachi repairman ". I had taken the back off to check the guns to see if they were dirty and saw the rubber bulb on the side each gun . Is this filled with a type of liquid ? If so the bulbs had indentions in them as if they were not full. Also the guns have a slotted track with a wing nut to hold them and I assume that this is a focus adjustment . If so could the guns be out of focus ?

Yes each gun is filled with liquid that acts as a coolant. yes u have a convergence problem and a much more complicated one . much better if u will bring it to hitachi service center. there, they have special test equipments like the pattern generator to adjust the convergence. Good luck!

My 53UWX10B has a picture problem. Picture is blue and yellow and the yellow is offset to one side a couple of inches. Gives a "ghost" image.

If the picture is 3d looking in some way----it is a convergence problem; many of these sets have "magic focus" and if it will not correct the problem the two convergence chips need to be replaced---this model should use either STK-392-110 OR -150 CHIPS.

This can be a do it yourself repair if you have some skill and total parts cost on Ebay would be under 25 dollars.

Let me know your skill level here and I will instruct you how to do the fix.

Sony KP-51WS520 51" Rear Projection Colors have been over saturated for awhile...selecting vivid seemed to help. But now I am getting a ghosting effect on most words, always to the right.If I go to...

The most likely cause is shorted convergence chips and possibly a few pico fuses.

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 a convergenece repair kit with instructions from the links below.

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

Problem #1) Convergence

Yours may have one or more of the following symptoms...

*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

You can see some more examples and find a fix here

Rainbow ghosting

You need to replace both convergence ICs there numbers are STK392-110 this is a easy inexpensive repair if you do it yourself. Takes about an hour beginning to end. You can order your parts at the following link and they provide free instructions with pictures and also free on line tech instant messaging while you do the repair. I am one of the support techs for them I do the instant messaging during the repair. Heres the link. You'll need two STK392-110 Convergence ICs.

Convergence board

It wouldn't be the entire convergence board, you more than likely have a bad convergence STK-IC. Replacing the IC will take a good bit of knowledge and training as far as electronic repair is concerned, plus a complete convergence set up. In other words, unless your certified, you need to contact a tech. The convergence set up alone has driven men to drink.....
