Question about Samsung HCM653W 65" Rear Projection Television

HCM653W color convergence off

I replaced the IC 392-040 sub-conductors in my tv and the color convergence is still off. I can adjust the red but can not adjust the blue. The image on the screen is bowed at the bottom and top as well as both of the sides. What could the problem be that I need to fix, and is this something that I can do by my self?

Ck low ohm resistors 3.9 omh and pico fuses they look like resistors but they are green or yellow 5amps, 6amps,sometimes after replacing STKs there is bad resistors or open pico fuses.

Colored lines at top and bottom when tv comes on and seeing double vision in different colors at all times


If your tv is not a DLP the problem is in the convergence, try to adjust it using your original remote control go to the setting menu then to the convergence section. Adjust the red and blue convergence. you should move the red and the blue in up, down and left, right if this color does not move far enough your convergence IC is already defective. Replacing this convergence IC will solve the problem. In locating this convergence IC you should remove the back cover of your unit but be sure to unplug it before doing this. This convergence IC is attached to a large aluminum plate, it is the heat sink, and it has a marking of stk- ### followed by numbers. You can try to pull it out using a soldering iron and soldering pump but be careful you may damage the board and cause much problem to your unit. Or you can contact a technician to do it for you and save you from stress good day and best regards.

My screen looks like its 3D.


Your tv has a problem with the convergence, adjust it using the original remote go to the setting's menu then go to the convergence section. Adjust the convergence color red and blue the green color is your guide you cannot move this green color, then you should move the red and the blue in all direction left to right, up and down. If you cannot move the red and the blue far enough the convergence IC is defective it must be replace in order to align this convergence. Feel free to send feed back good day and best regards.

I have some distored blue color across the screen


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.

Convergence problems are very common on all Projection TV sets including Sony, Samsung, JVC, Philip Magnavox, Panasonic, Akai, Pioneer, Hitachi, Zenith, and others. You can get a convergenece repair kit from the link below.

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 - TV may also make a chirping noise.
Here are some photos of convergence problems.

Here is a quick test....

Using your original remote go-to the settings menu then goto the convergence section.

Try to adjust the red and then the blue convergence.

You should be able to move RED and BLUE in all directions - up, down, left, and right.

If you can't move them in all directions or cant move them far enough your convergence chips are bad and should be replaced. This is a common problem.

Note: If you TV has as flash focus or magic focus button only try pressing the button. If it fails to fix the convergence your need to fix it. See below for a solution

You will need to replace the convergence chips and possibly some convergence resistors and pico fuses.
This is a a fairly easy DIY job if you know what you are doing. If you have never done this before we would advise calling a shop or if you want to do it yourself get a complete kit with instructions and support from www.TvRepairKits.com

Can't control red convergence on VS-45607


The STKs are three channel ICs they each control horizontal and vertical of one color the third channel controls part of green and the other half of green is controled by the other ICs third channel. Its customary for the Ics to fail and only have one channel bad in the IC. However its recomended to change both because of the bad Ic having green it can actually weaken the other IC and that one will fail shortly.

RGB COLOR PROBLEM.


You will need to check the plus and the minus convergence voltages in the main power supply. There are a couple of circuit protector fuses that go bad. Do not replace these untill you replace the convergence IC's or you will cause more problems in the main power supply. Good Luck
