Samsung HCN4727W Rear Projection TV, green screen, audio works


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,Akai2_bing.gif,Pioneer, Hitachi,Mitsubishi,Zenith and others.
You can get more information and a DIY convergenece repair kit with instructions from the link 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

Sony kdf-e50a12u rear projection lcd bravia. red shadows


This is due to you having a projection tv, some projection tvs are really bad for game playing and especially if you have a hdtv. even in the p23 manual it says that you shouldnt use with a projection tv cause it can damage your tv's screen permanently. I personally still play mine but, thats likly the problem.

My picture has double image and red shadow top and bottom


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.

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.

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.

If the images are different colors (red,green,blue) then the convergence has diverged. Some TV allow re-convergence through the menu screen, older sets my need to be physically adjusted (aimed) to clear this up. a strong knock to the TV may have cause this.

Panasonic PT-51HX41 rear projection tv showing shadow/double images.


Unplug the TV from the ac wall outlet for about 4 minutes then plug it back in and turn it on. If it still has a double image then tell me if it's affecting the menu screen from the TV (not the cable menu). And is the double image in red and blue?

I am having a shadow/double image problem only on the left side of the screen


Yes its called the Convergence ICs there are two of them they are mounted on a huge heat sink with the part number stamped on them they will have a STK number such as STK392-110. they have 16 pins on them there are two cost around 10 dollars each, you will also need some Heat sink Compound. Just look for the largest heat sink in your tv and thats where they will be. However if you can move both red and blue colors up,down right and left its probaly not your ICs. Do the colors move in all directions? If so you probaly just need to do a multipoint convergence adjustment.via of the service menu. Hope this helps. let me know if you need anything further.

Has a shadow on picture. Red, Green is not alligned


You need to set your convergence. Check your owner's manual on how to do it. I'm not sure the exact procedure on that model, but usually you can find it in the setup menu of the tv. What you're trying to do is line the red and the blue up perfectly with the green so that they all blend together to give you one picture.
