Do not adjust any knobs as instucted in the previous thread if you TV have a convergence problem. Doing so will only make things worse. The blog does however show you how to fix other common problems with these sets.

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.

Does the light flash 8 times after it shuts down? Take a look at the site Jean posted, it sounds like the problem that this site will help you fix.

I have blue arched lines on my sony kp 57wv600 is there a fix for this


Those are retrace lines, the screen controls which are a technical control located under the front gray panel of your tv needs adjusted. This also could be an indication of a bigger problem, most common would be the focus block failing. it could also be of the picture tubes failing but this is not as common or possibly the crt driver ic's. There are specific diagnositc steps to preform to isolate the potental failure. this could lead to the tv going very bright then shutting down.
The first thing a tech is going to do is to adjust the screens and leave, somtimes this is enough, but sometimes it is not. if you want to try and adjust the screen i have an instruction set below, but i must warn you that there are high voltages present when attempting this adjustment and can be dangerous if you are un familure with tv repair.


Turn your color all the way down and the brightness in the middle, then find the focus block, it will be a block with 6 controls one row will say screen the other will say focus near the picture tubes, adjust the screen controls(one control for each color) until the picture has a good black and white look to it, then turn your color up and it should look fine. This is how i balance out the picture. But there is another method that allot of techs use, the other method is to adjust the brightness up until you see what is called retrace lines it is a jagged line going down the screen, once you see these lines back the adjustment down just until they disappear. Do this for all three colors. This method works but on an older set can throw the white balance off because of tube wear.

My Sansung HL-S4266W just shut off one evening while watching. It had all 3 lights blinking and it had been over 3 years since buying the tv. I replaced the bulb, nothing changed the tv would still turn on...


this could be the color engine or a power supply problem. My suggestion is to not put anymore money into this tv, its an old technology and you will be replacing parts for it every 3 or so years. eventially the parts will not be able to be found. Go get a new tv, save yourself money and headaches.

Tv gets bright and then get dim and dose this the entire time tv is on


If you watch a DVD, does the picture also flash? If not, it might be just the TV signal. Are you using a cable/satellite receiver? If so, check it's connections. If anything viewed on the TV, using different inputs and a different cable/wire, is flashing, it is a problem with the light engine or color wheel, if the TV is DLP.
