Hi sbsoto,
If the symptom didn't cure by convergence adjustment through the remote control, this is an indication of faulty convergence board inside. You may replace the convergence IC's and some of the resistor around because its already gone bad. You may also replace the entire convergence board for your convenient. If the board replaced with new one, your unit will back to normal again. Also, consider bad solder jointsin that area, it will do the same symptom like what you've encountered right now. Find it first and re-solder. If you don't have necessary tools and test instrument and can't do the job yourself, I would advise you to look for a qualified technician to isolate the problem.

Hope I helped you.
Have a nice day!
Thanks for using Fixya.

Sony 51" Rear Projection TV is blurry with colored ghost images


Thats caused by a convergence failure. The Sony type 1 convergence repair kit from www.tvrepairworld.com will usually correct that issue the kit contains the components and the CD with repair instructions so you can repair yourself.

My projection tv has ghost pic you can see three dfferent color lines


Go into the tv menu and look for "convergence" this is a setup issue that can sync your colors. Projection tv's have 3 projectors inside, each a different color, if they get out og sync it can cause a blue or red ghost. In your tv menu you can look for noise reduction and turn it on also scan velocity modulation turn that on as well. These can all be found in the menu under picture or setup.

Color alginment is off


Your TV most likely has one of two possible problems.

Problem #1 - Failure in the convergence circuits. ( 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 are some photos of convergence problems.

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.

You will need to replace the convergence chips and possibly some convergence resistors and pico fuses. Its a fairly easy DIY job or you can call in a pro. If you want to do the repair yourself check the site www.TvRepairKits.com. Their kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, thermal paste, email/phone support, 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. Notice how dull the colors are and how white the screen looks. The screen may also look red, orange, dull, etc.

TV set after fluid change. Notice how bright the colors are now. Everthing looks crisp and sharp again.

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.

Color ghosting or shadows


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

You can see some more examples and find a fix herebb0cf99.png http://www.fixya.com/support/r2861467-solution_video_looking_whiteish_dull

No real color picture, looks like an undeveloped negative, ghost


The pictures are indeed negative.  When scanning negatives or transparencies make sure you have the scanner set to the appropriate setting, otherwise simply Invert the colors in Photoshop, or similar photo editing software.

There are 3-4 issues in here,one of them might be a bad convertion part in there. It is not worth your time and money to guess the issue,if it is under warranty,you should take it back.If not,repair tech. would be the way to go!
