Do you mean that at the top of the picture, the red color has shifted downward, bowed towards the center? If that is what you see, one color suddenly bows toward the center on any side of the picture, then it means that one of your convergence IC's has burned out and needs to be replaced. It is a good idea to go ahead and replace both STK392-110 IC's with the newer improved STK392-150's. If you have never replaced convergence IC's and realigned the convergence circuits in a projection TV then allow a qualified tech to handle it for you.

I need a new remote control #CLU-613MP for my Hitachi TV model no. 60SBX78B.


Hey there, You'll have to contact the Hitachi local customer care and order a replacement. It won't be that much of a cost, maybe around $20 or so.

Common Projection TV Problems and Fixes


In this article we will will outline some of the most common projection TV problems, fixes, pros and cons, and average lifespan.
Average Lifespan: 7-20 YearsPros: Large screen size and excellent picture quality. Some model support HD. Very reliable when they are cared for.
Cons: Heavier and bulkier than the newer plasma or LCD sets so if you live in a cardboard box it may take up a bit more room.
Common Problems/Fixes
Common Problem #1 - Convergence: One the most common problems that you will run into eventually is a convergence failure. This is when the TV colors do not align anymore and the TV will look 3D, warped or distorted. This is a very common problem and a fairly simple DIY fix. Parts to repair this can be found over the internet from sites such as www.TvRepairKits.com . Below are a few photos of a typical convergence problem and a link to a video on YouTube with more details.

Notice how the image looks 3D...this is a classic example of a convergence failure...it may also look warped or have a wave look. But the wave will not fluctuate.

Common Problem #2 - Dull or Dark Video
The second most common problem we see on projection TV sets is whats known as the dull video issue. This is commonly caused by discolored cooling fluid in the lenses. Over many years - usually around 5-7 years - the fluid will discolor and cause the video to wash out or look dull. Changing the CRT fluid out every 7-10 years will restore the image clarity back to factory new conditions. You will actually be amazed at how sharp and clear the video looks once a fluid repair has been done.
Here is a before and after photo notice how it looks washed out. In some cases the images will look like they have halos around them or the screen will have a reddish tint. Bottom line - if your projection TV has never had the lens fluid replaced the video is not as sharp as it can be. You can get fluid kits from the same sites mentioned above. Doing this repair yourself or through a shop will make the video look amazing.

Common Problem #3 - Dead set with no videoIn these cases there can be more than one common issue depending on the TV brand and model. But to make things simple if the TV has no audio or video and its making a constant chirping sound the issue is caused by a short in the convergence. The fix is to do a convergence repair. If however its not chirping constantly it can be one of many issue from failed capacitors, diodes, flybacks, etc.

Updated! Convergence Problems & Solutions - With example photos


Projection TV sets have two very common problems. One is convergence ( 3D/Warped video) the other is CRT fluid ( Dull Video). Below are more details for both items. Also, complete repair kits with instructions and repair support are avail from site such as www.TvRepairKits.com

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.

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. The power light will blink. TV may also make a chirping noise.
Here are some pics of convergence problems.





SOLUTION #1

What you will need to do is convergence. You can get a repair kit from TvRepairKits.com . It includes replacement parts,step by step instructions, support, etc.

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.

SOLUTION

What you will need to do is replace the coolant and clean the crt. You can get a repair kit from TvRepairKits.com . It includes replacement coolant,step by step instructions, support, etc.

Here is a quick test....

Using your original remote go-to the settings menu then goto the convergence section.

Try to adjust the red and then the blue convergence.

You should be able to move RED and BLUE in all directions - up, down, left, and right.

If you can't move them in all directions or cant move them far enough your convergence chips are bad and should be replaced. This is a common problem.

Note: If you TV has as flash focus or magic focus button only try pressing the button. If it fails to fix the convergence your need to fix it. See below for a solution

93a1209.pngCONVERGENCE SOLUTION

You will need to replace the convergence chips and possibly some convergence resistors and pico fuses.
This is a a fairly easy DIY job if you know what you are doing. If you have never done this before we would advise calling a shop or if you want to do it yourself get a complete kit with instructions and support from www.TvRepairKits.com
