Red color halo/shadowing

It sounds like you need to re-adjust your convergence. The purpose of adjusting your convergence is to align your red, green, and blue colors. Moving your TV often causes this problem. I hope you get it going.

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.

This tv have a problems known as a convergence problems,it dead.The tv colors lines R,G,B mis alignments,have colors shadows pictures or 3D pictures look alike?The tv convergence board have 2 dead STK convergence ICS and some or all of it resistors are dead too.These parts on the tv convergence board,must be replaced to solved the tv convergence picture problems.The shop,will cost u like $300-350 for parts and labors.

These sets have several common problems listed below.

Problem #1) Convergence

Symptoms:

• Screen Looks Distorted/3D
• Colors wont align
• Screen may look distorted
• No Audio/Video - makes a chirping sound.

Problem #2 CRT Fluid has clouded over. Symtoms

• Dull looking screen
• White looking sceen
• Halos around objects
• Red/Orange looking

This sounds like convergence output IC problem. convergence board would have to be removed - remove and replace 2 STK IC's and check the surrounding resistors. Shops usually $200-$400 Be sure to vote/rate me if this helped Thanks!

Both convergence amplifiers should have been replaced at the same time. If you can get your hands on a service maual, replace both of them, and go through the convergence alignment in the manual.

Your TV most likely has one or more 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.

Solution #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.

Solution #2


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.

TRY THE MAGIC FOCUS BUTTON. IF THIS DOES NOT CORRECT THE PROBLEM YOU WILL NEED A SERVICER TO GO IN AND REPAIR CONNECTIONS OR REPLACE THE CONVERGENCE IC'S AND OR RESISTORS. AND READJUST CONVERGENCE IN THE SERVICE MODE.

try adjusting the color purity knob.one by one,or if it is really bad tube u can extend it by rejuvinating it.
