If it is fading on all screens (menus included) then it is the picture tubes. If it only fades when source is played, it is the tuner electronics.

Do not adjust any knobs as instucted in the previous thread if you TV have a convergence problem as shown below. Doing so will only make things worse.

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.

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.

michael_tede,

You state that there is a problem with the unit. Knowing that, it would not be worth more than $50 to $100 and only to someone who thinks they can repair it. If you don't want to fix it and want to get something for it, your best option would be to dissassemble the unit and sell the separate parts on ebay. Doing it that way could net you as much as $500 to $1000. Good luck with the sales. I have a tip at http://www.fixya.com/support/r6981868-replace_circuit_board_in_modern_tvs which might be helpful for removing and handling the circuit boards,

everettewing,

We do not sell parts but I can tell you where to find them. If you broke the entire screen you will need to purchase three separate screens. Projection screens are made in three pieces and laminated together. The parts you need are available at http://www.encompass.com . The fresnel screen part #4-084-702-02 ($125.00), Diffusion Plate part #4-070-525-01 ($151.00), contrast screen part #4-081-065-01 ($125.00). Freight could be between $45.00 and $150.00 due to the parts being oversized. I have a tip at http://www.fixya.com/support/r6210638-replace_broken_projection_tv_screen which explains the repair/installation procedure.

All projection TV sets have two very common problems. One is convergence ( 3D/Warped video) the other is CRT fluid ( Dull Video). Here are more details and solutions for both.

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

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.

Picture of a set that needs the fluid changed.

A double pcture with two different colours??? more seriousely the rainbow effect could be of an appature grill un hooked in one of the three tubes (THIS IS DANGEROUS IT COULD IMPLODE) you should have a proffessional looke at it and you should NOT USE OR MOVE the TV until then.

Good luck!

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.

This is a very common probem on all projection TV sets. Not just sony. Your convergence IC chips and related parts have failed due to normal wear and tear. One common symptom when this occurs is your TV will look 3D and convergence won't adjust correctly. A repair shop will charge around 250 - 400 for the fix. Or you can get the parts and do it yourself. You can get complete parts and instructions from sites like www.TvRepairKits.com or if you know how to do these repairs you can gogole the parts and forgo the instructions.

Hope this helps a bit,

This is very common for these types of TVs. Has it recently been moved or bumped? Or possibly exposed to a surge. - READ Warning below.
This is an issue with the color guns being out of alignment. This will require a TV expert to fix. The color guns are controlled by wire field coils wrapped around the CRT or main picture tube. Possibly the glue used to hold them in place may have let go some. I kinda know what to do, and I find it very difficult to do a good job of aligning the guns to produce a clear picture. Take it to a TV repair shop or have them come out to you would be better, because once aligned, it may shift again while being transported home.
WARNING. There are VERY high voltages in back of your set. In the 40 thousand volt range or more. Don't mess with it yourself unless you KNOW what you are doing. Don't guess.

For the money - I'd look at a new flat screen.. !!!!
