Hitachi 42 hd projection tv

Question, I am having a ghosting issue with my tv. It does so with the picture and the information bar. I tried to adjust it via the converge option but to no avail. Im sure this is a common problem, I am fairly handy with electronics but have never touched the inside of a tv. What do you guys think the problem is and is this something I should try and repair myself as I am on a tight budget? Thanks for your help..

With out a model number to ref to just have to give this a stab. Sound like you are talking about a projection set that has convergance Ic failure, Hitachi put out a kit that has all the most common parts to repair you set, but there are about 4 kits and need a model number to get you the right one

I have a60 inch hitachi projection tv. I tried to fix the screen alignment using the grid but the blue line doesnt move to line up on the grid. The green and red work fine. So theres a blue ghostly glow...


you will need convergence work done & for Hitachi I recommend a professional as the convergence will have to be reset for normal & HD pictures. See if you can get a quote from a local servicer.Be sure you are sitting down.
I really think your money would be better spent on a 21st century LED or LCD TV.

Model 50UX58K - picture has distortion & shadow on right side of screen


Hi, if the shadow is colored lines then you probably need the convergence ICs and possible reisitors near them replaced .
If the shadows is just like a ghost of the image or a bar from top to bottom, then check if it does it on every input (dvd for example) , there are blanking bars that you can't see past the edges of the picture and when you have a bad cable signal you can see the ghost of the blanking bar sometimes. if it does it does not show the shadow when watching a DVD then its a signal issue with your cable/satelitte .
If your convergence is the issue, try the adjustments first and if that doesn't correct it, you can replace the ICs using kit # x480293 or stk392-110 (2 ICs) soldered in very technical for even a technician.
repairman cost about $250-$350
hope this helps

How do I adjust the HD quality for a crisper picture? I have tried Magic Focus, but need to know where the sharpness or contrast can be tweeked .


The magic focus function is to electronically align the red, green and blue beams. So all it can cure is colored ghosts. The contrast, brightness and sharpness adjustments are in the customer menu settings. With the remote just push menu and select video or picture adjustments. Those adjustments are in there.

Pictures very dark, Brightness all the way up. Contrast does not adjust


I have the same problem. I was able to temorarily fix the issue by taking the back cover off and blowing all of the dust out. But this only worked for two days. Now the problem is back. Did you fix the issue with your tv? Thanks.

Hitachi, model 57UWX20B ghosting?


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,Pioneer2_bing.gif 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

Black side bars on hd channels


You may have to refer to the instruction manual for details.

There should be in the menu set-up an option to set the aspect ratio for the different broadcast modes. Normaly, when viewing a 4:3 picture on an HD 16:9 set, the sides will be cut off, otherwise the picture will be stretched or compensated.
