Green line around the screen


Look for any magnetic materials around that area. Try changing the input device to something you know works for sure.

Sony KP-51WS500: This TV comes on for a few seconds of picture and sound. Then the picture fades to green and then turns off within another 10 seconds. Is this a power supply problem? Or should I look in...


Adjust the Green screen drive,turn it down and see if that corrects the problem.
Remove the Front Bottom Panel on front of Tv and behind it will be the Screen/Focus Control block
It will have 3 controls on Top for Focus to each Tube R/G/B
and under them are the Screen drive controls for R/G/B.
But if adjusting the Green Screen Drive Control does not Fiox It ,then you have a Bad Green Tube.

Screen dim, black has green in it, contrast and brightness = shin


Since you have replaced the Color Wheel, it sounds like you have not adjusted the Index Delay in the service menu. First reset all of the picture settings you have adjusted back to original factory settings. Then on your Samsung TV Remote and with the TV OFF, Press Mute,Power,123. This will turn on the set and put you in the Service menu. Look for the top setting and select or scroll to the OPTION setting and select and look for INDEX DELAY and select that. Once you have the Index Delay selected use the right and left buttons on the remote to adjust for a picture the has no abnormal coloring and while looking at a program adjust for when the blacks look black with no abnormal coloring. Once that is done, turn off the set then turn the set back on. Now the picture should look normal.

My tv is damaged and i want o fix it


Cannot fix it yourself, the very sensitive connection area on top of the screen is damaged. Unfortunately this requires a whole new panel, it will be cheaper to get a new tv.

Coulor distortion at the top left of the screen


Hello jordan ashe,

This is an indication that the green CRT is having a convergence problem. This might be caused by the convergence amplifier or by the CRT. Does the rest of the picture look OK? and in addition can you supply a picture of your TV so as I can see what you are seeing and develop a proper diagnosis?


Thank you,

Green semi-circle of lines on Samsung 55" HDTV (projection)


I believe i have the same problem myself. When my TV is on any of the Component Inputs without my DVD player turned on i usually get the normal green screen. But now that is a dip in the green at the top of the screen from the top left to almost the top right and black pushing down on the dip. Almost like a green curtain was sagging at the top and you can see the black behind it. It does this on every input and distorts every picture you see. The distorted picture has all the green slightly off from where the rest of the picture is and where the dip at the top of the screen is there is somtimes purple instead of black.

I know the basics of how the picture gets onto the screen and its my guess that the Green "gun" for lack of a better term and somhow come loose, or been missaligned to a great extent. I would love to find an answer to this problem, and anyones best guess as to how much a repair man will charge, just so i know the ballpark.

Replacing the two STK392-110 ICs didn't do it for me. But you can try. I am experiencing the same problem, and it appears that is not possible to correct the problem with the ajustments in Service Mode. Please let me know if you find a solution to this problem. TIA.
