Question about Samsung PCK5315RX TV

1 Answer

Red,blue,and green separating

I have a HCL4715W tv. The colors are separating in a arch that comes up from the bottom of the screen. It started out small but has not become so large that we can no longer watch it. The words and pictures are all showing separately in each color. About 1.5 years ago it did this and I took it to be repaired. I did not know about this site. Can anyone suggest a solution, besides taking it back in again. It cost $250 last time and the tv is about 5 years old. Thanks.

When the display is dark i get red and green arcs on the screen


Hi,

Color arching is an easy fix. You need a screw driver and some patience removing the front panel. You will be looking for a box with 3 screws on it. This is the color gun. THe scews are Red, Green and Blue color only, however, they usually don't indicate the color on them. Turn the screw (Slighlty) till the arching is no longer there. You have to do this with the tv on.. LOL

Best Regards and Semper Fi....

Colors arched and overlapping


if the option for convergence is still listed under the setting section of the on screen menu, then you need a convergence power supply board. If the convergence option is missing from the menu you need the ITC222 convergence missing repair kit. You can get either one at the following link they include instructions for the repair.

Samsung three colors on screen, out of focus #hcl4715w


It is a convergence problem. The IC's (integrated circuits) or STK chips or the "guns". You have a red,and blue, IC's that provide all the colors. When the colors are out of convergence, you get ghosting or what looks like 3D pictures. I haven't been able to locate the part numbers for the IC's or STK chips but have located a convergence board. No luck determining if IC's are included (a phone call first to verify) but if they are, would make life much easier for you to install. Part # is BP95-00415H http://jr.partsearch.com/Part/Samsung/Samsung/BP9500415H/New.aspx?ModelMfgName=Samsung&ModelBrandName=Samsung&ModelNumber=HCL4715W

Typically, IC's cost around $10 or less. here is a link to a guy who provides pretty good instructions on replacing the IC's along with pictures.

The 3 colors are off, i have shadows and arches in the screen


It is failure of convergence ICs and these two ICs will be replaced on D board.
If you are comfortable with TV repair and know good soldering skills then can do the job easily.
Convergence ICs are mounted with sliver heat-sink on D Board of TV and part number will start with letter STK...
Get back to me if you need further info.

Color distortion and arched picture


Your TV most likely has one of two 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.

Re Degaussing


Now Degaussing and convergence are two different things, if you say its degaussing then you should have just a color differential in a certain area, meaning the color should not be arched, everything that passes through should pass throu only with the changing of color. Now if its a convergence the the color may lift upward in an arch, likely separated from the other colors, Red, Blue,or Green. So now which do you think you have? Deguassing usually give you a highish green color or yellow

Warped Picture, Separated colors


Each color (red,green & blue) has an amplifier IC (STK-).
When there is a convergence issue,the first step is change both
IC's for reliability. Then check for open fuses devices,usually
pico fuses.Then re-check convergence alignment.......T.
