Our samsung HCl4715W tv is all connected right but our picture is scrambled where you see double exposure and the color is off. Can not find our manual. any suggestions?


The problem of your tv is the convergence. Projection tv set has a 3 colors red,blue and green this 3 colors must be properly lined up to look the video normal. When this 3 colors is not properly aligned the video will produce a double image of color or like a 3d or wavy. In order to fix this problem you should adjust it in the menu program of your tv you should move any of the colors to up or down, left or right if you cannot align the 3 colors the problem is the convergence ic it must be replace. To locate the convergence ic you should remove the back cover of your tv but be sure to unplug your tv, you will see this ic attached in a large aluminum plate it has a marking of stk--- and followed by a numbers. or you could contact a service technician do do it for you and save you from stress. Good day and best regards.

Sony KP51WS510 in Rear Projection HDTV Television has red shadow


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.

For more more examples and find a fix using this link on Fixya http://www.fixya.com/support/r2861467-solution_video_looking_whiteish_dull

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.

I have sony model KP51WS510 with a red and green shadow also the color is off


Your TV most likely 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.
Here are some photos of convergence problems.

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.

0667c5f.pngSOLUTION

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 call in a pro. If you want to do the repair yourself check the site www.TvRepairKits.com. Their kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, thermal paste, email/phone support, etc.

Sony-kp51ws510 picture turns to a blue hue with flickering colors


hello there this is an easy fix unplug the tv and take the back of the set, once inside the set you will see 3 coloured bulbs and a big mirror in the back theses over time get dusty and dirty and if you smoke it can get really bad you simply just need to clean the bulbs and the mirror with computer screen wipes or some sort of window cleaner be sure not to get everything wet inside this should sort if for you nice and clear again!

Thanks For Using FixYa

Pincushion Picture on a big TV screen!!!


The set has 3 IC's(one for each color)strictly dedicated for the aligment of each color,if one them does not align is because is going bad or is already bad becuase picture can not be adjusted,the IC's can be identify because they are mounted on a heat sink and have the markings STK--- ---,they are all the same and need to be replaced with an exact replacement.If you are familiar with tv service you can replace them,sometimes the new ones need to be aligned from the service menu,you will need the service manual,soldering and unsoldering will be involved,If you are not too familiar be safe and seek the assistance of a servicer.
