Question about Hitachi 50UX57B 50" Rear Projection Television

50UX26B Convergence or Ghosting problem

My Hitachi 50UX26B has convergence or ghosting problems, three years ago I fixed it @ a shop and now it came back again. I want to know if there are any circuit boards that are sold as 1 piece instead of replacing some IC's, resistors and other components ..The teck needs $380 to fix it which in my opinion is too high to fix an old TV. but if the price of a complete circuit board is reasonable since they are almost obselete then i would be interested in buying a board and replacing it myself. Please let me know if the board is available , where can I get it and how much do I expect to pay for such a spare part. Thank you

Ghosting or a 3D image. A yellow and blue ghosting or shadowing image. Looks much like the top picture in the "picture ghosting image" entry. Is this a convergence problem?

Your convergence has failed and needs to be repaired. Once quick test is to goto your convergence menu and see if you can adjust red and blue. If not its has failed and needs to be fixed. You can call in a repair shop or you can get the parts and instructions from www.TvRepairKits.com and do the repair yourself. Its a fairly easy DIY fix.

The CRT's will often require mechanical alignment to center each of the three CRT's after the coolant has been replaced.

Ghosting and bad color, sound is fine.

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

The green and blue ghosting is a convergence problem that is either bad connections at the convergence ICs or defective ICs. If you can solder, try resoldering the ICs. If that fails to resolve the problem, replace them. These ICs are large black ICs attached to a heatsink. They should be marked STKxxx.
Keep us posted.

Misaligned Convergence

Is anenvolved job to repair a convergence problem,the way to go about it is to locate the convergence amplifier IC's,one for each color(red green,blue)check for loose conections at the ic's legs,after resoldering all the legs see if an improvement is present if it gets better you will be able to adjust from the custumer controls,but if no improvement the Ic's will have to be replaced.Some units have a separete board were you can adjust convergence after replacing the Ic's and other units you have to access the service menu to be able to do the adjustments but just doing this adjustments can be very challeging even for a train technician,I would suggest you seek assistance from a servicer and get an estimate.

I have a Hitachi Ultravision TV, model #50UX58B. It flickers. How do I fix it? It flickers, started doing it a while back. It takes some tapping on the side for it to work. We've even tried leaving on after we stop watching it, turning off the cable box, and turning it back on when we want to watch it, but it doesn't work either. What's wrong and how do I fix it?
