Yellow and blue shadowing, double image


It a 100% convergence problems.Convergence problems very easy diagnose.The picture look like 3D,colors lines don't lines up.Fuzzy,out of focus.Convergence controls don't work to lines up any colors cross.
WS-55511 uses a single convergence IC chip---a STK-393-110.
IF convergence is off and will not adjust it needs along with any of the 3.9 ohm resistors that protect it to be replaced.
What happens in these and most projection sets is the chip is mounted on a large metal heat sink with fins to keep it cool----a white grease is applied to the back of the chip to quickly transfer heat--after some years the grease dries out from the heat and the chip fails.
Considering you can buy the IC on Ebay for about 14 dollars plus shipping (I can tell you the best seller there to look for) if you or someone you know can do the repair you can save the set and a LOT of money.
Most shops are going to get 200-300 for this repair

There is a blue shadow to the picture. The color chips were recently replaced and it has been doing this since the replacement. I have tried to adjust the convergence but on the screen with the cross hairs...


STK ICs that were replaced maybe the reason convergence is not lining up or you may have some open low ohm resistors that need to be replaced ,near convergence ICs. STK392-570.
Mats Electronics has STKs for 14.95 each

I was told by a repairman that my convergence module is bad on my ws 55511 or best buy model ws b55 was wondering what a convergence module cost. my power went off and when it came on the red images were...


Any shop with experience should be able to replace the convergence ICs which are the likely problem. This type of repair will cost less than the boaqrd replacment and won't require a conmplete reconvergence adjustment. The parts cost around $25-$40 each (there are 2).

I would look for someone that is able to change the ICs rather than the entire board.

My Tv started shown double image yesterday. What


These sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the picture to look normal. This is called convergence.

When its out of alignment the video will look 3-D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the 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 Sony2_bing.gif,Samsung, JVC, Philip Magnavox, Panasonic, Akai, Pioneer2_bing.gif, Hitachi, Zenith, and others. You can get a convergenece repair kit wiith instructions from the links below.

Here are some of the most common problems with these sets...

Problem #1) Convergence

Yours may have one or more of the following symptoms

  • Screen Looks 3-D
  • Colors wont align
  • Screen may look distorted or warped
  • No Audio/Video - makes a chirping sound.
Problem #2

Another common problem is dull or washed out video.

Your set may have one or more of the following symptoms....

  • Dull looking picture
  • White looking picture
  • Halos around objects
  • Red/Orange looking picture

You can see some more examples and find a fix here

Hi,
Check resistors might have cold solder joints are changed resistance values around replaced STK393-110
Pay attention to faded colored or fried resistors.

Good Day;

Sounds like you have bad Convergence Output IC > 267P155010 > STK393-110, replace and it will correct the problem TV uses only ONE, make sure all resistors look good in the circuit around IC.
Good Luck, big IRISH.

Green shadows surrounding bright whites


finally a consumer that gives us plenty of info :)
sounds like an overdriven green tube, the only thing you can try is to find the G2/Focus block assembly, either behind front speaker grill or remove back of set and look for a black box approximately 5"X5" , this box will have 6 philips type adjustment screws(plastic) 3 are for focus, do NOT adjust these,
the other 3 are marked "screen" the center screen adjustment screw is for green, turn it VERY slowly counterclockwise while the set is running and pray that your problem dis-appears, be advised that this is a HIGH VOLTAGE device so one hand in your back pocket the other hand turns the screwdriver, if the problem does not go away you have a poor green tube, good luck, sorry I can`t give you the exact location of the G2/Focus block, manufacturers move them to different places every year.
