Question about Samsung HCL5515W 55" Rear Projection Television

1 Answer

Samsung HCL5515W the red convergence would slowly move. some days it was perfect others it was so out of adjustment you could barely bring it back with the on screen tools. then all of a sudden today the red is way out. across the center of the screen the picture is fine. at the top and bottom, the red looks like an hour glass on its side (the shape of the distortion). is this an expensive fix? this TV is eight years old, sees a lot of use and has never had the bulbs replaced. would it be worth it in the long run to repair or better to replace?

    I have the same problem. I can add that going to the menu screen sometimes causes the tv to shutdown and turn on by itself!

The tubes on these sets can last 15-18 years. Quite honestly the parts to repair this problem aren't very expensive, just knowing where to put them is. If the problem was caught early enough, resoldereing some solder connections would probably have solved this, but now you may have to pay a repairman 150.00-350.00 Most of which is labor. Anyway, if you fix it properly you could get several more years of enjoyment out of this set. Let me know if I've helped. Good luck.

Red and blue convergence


Adjustment or IC replacement---the adjustment with the original remote via the customer menu should be tried first----set if has convergence should use either two stk-392-040 or -020 chips that are interchangeable with the -040 being the higher current part and more expensive.

CONVERGENCE IS OFF PINK AND GREEN LINES ON THE TV SCREEN


Projection TV2_bing.gif 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, Samsung2_bing.gif, JVC, Philip Magnavox, Panasonic, Akai, Pioneer, Hitachi, Zenith2_bing.gif, and others. You can get a convergenece repair kit from the link below.

Common Symptoms include....
  • Screen looks 3D2_bing.gif
  • 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 flash2_bing.gif 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

How do you adjust the focus lenses for an HCL5515w TV?


You have one of two problems. Sometimes both.

Problem #1) 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.

Problem #2)

Your TV may have a convergence 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.

You will need to replace the convergence chips and possibly some convergence resistors and pico fuses. Its a fairly easy DIY job or you can hire a pro. If you want to do the repair yourself check the site www.TvRepairKits.com.

Samsung HCL5515W...when using coax input pic convergence is off, red and blue seem off....when I use the component inputs it constantly flickers between the squigly lines and picture with convergence off?...


on component your device may have to be on progressive. old dvd players you could switch back and forth on progressive and normal. the squigly lines sound like you need to make sure its on progressive. hook it up using the yellow video slot on player and tv (any cable will work). go into menu and look for progressive and change it on.

Convergence out and turns itself off


This is a convergence problem that should be relatively easy to resolve, I am assuming that the set is new to you rather than new. If new, it should be under warranty and if opened would void the warranty. If new to you and you can solder, you should be able to fix this. First, realize that there are potentially dangerous high voltages present inside the set even when unplugged. Locate the convergence ICs (large black ICs attached to a heatsink and marked STKxxx) and resolder the pins. That may resolve the problem. If not, then replace the ICs. Check the area for small valued resistors that may be defective as well.

Keep us posted.

Convergence problem


We need a better description of what you mean by shadowing. However I am assuming: 1. You mean it ''bleeds'' off to the right when you have something with a hard red/blue drive. 2. When you turn the contrast and color down a bit it gets better. unfortunatly I cannot tell you how to fix convergence, but I can think of some other possibilities. In this case the red/blue emmision of the crt is dying off and going into saturation when driven hard. To fix, replace with a new picture tube/crt. In some cases you can get a little more life out of that tube (with a watchable picture) by having the screen, focus, cathode bias, and drives slightly readjusted. It will take someone with experience in doing these adjustments on a weak tube to get it looking as good as possible. Given the construction of the cathodes (guns) in that crt, only a very low level crt reactivate should be tried on it. The hard rejuv most crt testers give is highly likley to completely destroy the cathode on that crt.

Distorted Color and geometry of Picture


I've posted this solution several times but here goes. Try setting up the convergence through the menu by accessing the convergence setup menu. If this fails to work you have a bad digital convergence box and need a tech to replace it. About $60 to $100 fix.
