After about 30-60 minutes TV starts to hum and picture gets distorted, could this be the color wheel...???


Sounds like a sync problem due to color wheel speed. clean and lubricate color wheel motor with tiny amount of Z-Max lubricant (liquid Buckey balls, available at Wal-Mart), on each bearing. make sure wheel is free-wheeling and turns easily. Should cure problem. If the color wheel is in good shape, there is a power supply problem, which may be due to dried out electrolytic capacitors or a regulator that's failing. Troubleshooting or controller board replacement may be needed. Regards.

I replaced both backlight boards but still having problem with LCD TV...it is too dark and color distortion.


Fault to its main board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. http://electronicshelponline.blogspot.com/ . In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.

My sony wega kf-50we610 unlike every one else i have no problems with set turning on my problem is i cant watch anything do to the picture being distorted scrambled like i can see the menu options and...


It looks like the vidoe board but the fault can be also a distortion in the horizontal / vertical section. So check the PIN amp and related sections. What must be looked is of the HSTAT can be off set.
Deguass the set well to confirm if there is any possibility of a distortion of picture by a severe magnetic field.
Since there can many problems associated with a distorted picture but you can try and see these possibilites other than the Y amp processing. Hope my suggestions helps.

I have some distored blue color across the screen


Projection sets have two very common problems.

The first common problem is convergence


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 more information and a DIY convergenece repair kit with instructions from the link below.

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

*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

On the lower 1/2 of the screen on my panasonic 53 inch rear projection tv the colors are out of sync


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

Distorted picture that curves up at the bottom of the screen


My 9 years old Mitsubishi WS-55857 had the same problem (distorted pictures) for couple of months and I was about to buy a new plasma TV. But, I found TvRepairKits.com and I decided to give a try before buying a new TV. I received a convergence repair kit in two days with web site info for detailed instructions with many picutres to explain the process. When I had questions and Ed was very prompt to answer my questions thru the e-mail. I never done solding before, but I am moderate handy person. I spent less than $100 and three hours and my TV picutre looks stunning. I went thru advanced convergence process after I repalced the convergence chips and replaced RCA video cable with better quality and my TV picture looks as good as brand new. Thansk ED for your help!

3D effect caused by failing convergence chips on the internal control board. You will need professional intervention to repair or replace this board or the chips. Often this is in association with other parts that need attention and is not a DIY.

Picture is all distorted ,colors dont match up need 3d glasses to watch


HI, this is basic convergence failure. the convergence board controls the RGB stream and , if its malfunctioning or, the convergence chip set is damaged, it will distort the entire display and the colors will not be regulated correctly as you are experiencing at this time.

simply replacing the convergence board in this unit will fix your issue.

Color distortion and arched picture


Your TV most likely has one of two possible problems.

Problem #1: Convergence Chip Failure ( common problem )

Here are some of the most common symptoms and example photos of a convergence problem
  • 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.

Here is a quick test....

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

Try to adjust the red and then the blue convergence.



You should be able to move them up, down, left, and right.

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

2c07611.pngSolution #1

You need to replace the convergence chips and convergence resistors. Check the site www.TvRepairKits.com. They have put together a kits for most models. If you don't see a kit for your set send them a quick note and they will put one together for you. Their kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, etc.


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.

Picture of a set that needs the fluid changed.

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