Warped Picture, Separated colors

U still have a convergence problems,check all those resistors all around the 2 STK convergence ICS.All these resistors,must have the wright resistances and torance to have the tv to have picture convergence to function correctly.

the convergence circuit needs repair. You can get the convergence repair kit from www.tvrepairworld.com which contain the parts and the CD with instructions.

Green slanted lines from left to right, especially visible on blank or dark picture is CRT bias circuits problem.

HI, thank you for visit fixya.
Common problem on this set .
Picture tube liquid is dirty.
Mostly in crt green and crt blue.
Do you have electronics skills?. If so, open the TV ( back cover), you will see green,blue and red gun. After turn on your tv, select any channel or video signal, cover with piece a paper two guns at the top ( any), and see how look the picture in the front, try one at time, ( press menu on remote control and see leters-clear). I am sure the green and blue will be no clear. all the time red tube is fine.
REPLACE COOLANT LIQUID PROJECTION ( solution).
I will be here for any quetions.
Thank you

even if you had the original remote you
could not adj the pic for the failing convergance
chips. have a shop swap the chips . its
takes me about an hour + .price should be
no more then 175.00 part/labor. ps you
will may need to order the original remote.
to set up the convergance , wait have the
shop do that for you.

There are two common problems with Projection TV sets. Problem #1) Convergence Symptoms:

• Screen Looks 3D
• Colors wont align
• Video may look distorted

Problem #2 CRT Fluid has clouded over. Symtoms

• Dull looking video
• White looking video
• Halos around objects
• Red/Orange looking video

You can see some examples and find a fix here...

SOLUTION http://www.fixya.com/support/r2861467-solution_video_looking_whiteish_dull

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.

Picture of a set that needs the fluid changed.

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.

You need to replace both convergence ICs STK392-120 they are an easy repair you will also need (4) 6.8ohm Convergence resistors. You can get replacement ICs and the resistors at the following link and they will provide free installation instructions and free on line tech support so you will be able to do the repair yourself and save about 400.00 for a 45 minute repair. heres the link.

your tv has a prolem in the color circuit there is a ic that controls this circuit changing it will restore your tv to normal.since you are not a tech have a tech look at it for repairs.good luck.

You have to go into your menu and into setup then look for convergence, don't know exactly where since the TV isn't in fornt of me. But once you get there, there should be a bund of "+" all the ones thare are in color you need to change to white. Depending on the TV you would use our left or right arrow keys, enter or ok. Hope this helps.
