Hello, my Kp-48ks1 projector for many years, has a problem. looks as if 3D? double image, only at the top of the TV! Thanks

You may have turned on a 3D (side by side) mode.

Have a look at your remote, press the 3D button (you may have to press it several times) to cycle through the virtual 3D modes.

Once you see "3D off", the double image should go away.

If you want to use 3D again, simply cycle through the modes to go back to where you want to be.

Video IC problem. Contact any service technician. This is not a user repairable fault. If you wish to get some details, check the site linked here. Pull up older posts. Check the site in 'Mosaic' view. It will make search easy. http://electronicshelponline.blogspot.com/

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. Repair kits with instructions are also avail from www.TvRepairKits.com

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.

BOTH OF THE STK-392-560 convergence chips need to be replaced; there are also fuses on the power board that protect them--do not look like fuses; if you need photos of the place where the chips are and the fuses, let me know.

Repair takes about a hour and parts if purchased on EBAY will be under 25 dollars.

Hi,
Your question shows its Samsung rear projection TV that has 3 tubes to project picture.
Symptom shows TV got problem in convergence board that will be replaced.
Model number or TV would help me to provide you more info.
Thanks.

That symptoms are due to failure of convergence out ICs in your TV that will be replaced to get correct converge picture on front screen.

There are 2 big black IC mounted on big aluminum heat sink and number would be written on as STKxxx, these 2 ICs will be replaced.

If you want to repair TV by yourself then confirm model number of TV to provide you more info or call local tech to replace said ICs.
Thanks.

Hi,
It sounds TV got convergence out ICs failure problem and causing 3D image or outlined picture.
There are 2 convergence out ICs mounted on D board in TV that need to be replaced.
Let me know if you need part number of ICs if you want to replace by yourself or call local Tv tech to fix it.
Thanks.

my tv looks like a 3D picture! it has a double image and a the outside of the picture starts to curve

the convergence IC`s and associated resistors have to be replaced, do not repeatedly push magic focus or the alignment after the parts change out will take longer which of course means higher repair bill, good luck

I had the same problem with the same model earlier this year. You need to have the convergence module replaced on a circuit board inside. Expect to pay $400-$500 to a qualified repair shop.
