A "green" outline that appears on bright or white objects, especially if sunlit.
My 6-year old Mits. WS-55807 has been a good performer...really have had NO major technical issues with the set (I have some burn-in as the result of my ignorance in the early years about static images being left on the set too long).
The 1080i hi-def is sharp and clear (Comcast DVR) but there are two things I'd like to ask about:
1) I don't seem to be able to crank up the Contrast like I used to, although what I do get is quite acceptable, but there are times I'd like a bit more (especially when viewing a DVD) but it seems to be giving me about as much as it can (note: I do not maintain the Contrast at peak level just because I know it's not good for the set but admittedly, was not always this careful right after purchasing the set).
2) About a year ago I noticed a "green" shadow that appears next to an image (usually but not always on the right side), a good example would be the lines on a Tennis Court or on a road (especially if sunlit)as if a green highlighter was used to paint a green shadow, they will have a distracting green line right next to (paralleling) the white line. I also see this green effect when there is a "window" in the picture (say being viewed from "inside" a room with bright sunlight outside).
I find I can reduce this green shadow by reducing the Contrast, but then I'm getting a "flat" picture that is not pleasing to watch.

you have convergence menus
Coarse Green Tilt
Coarse Red & Blue Tilt
the TV should have a Crosshatch or convergence signal
green done first to make it level
then blue and red to match the green
be carefull not to change any other setting other than the Tilt; because you can really mess up your convergence
if the menu adjustments dont do this for you:
you have a light box assembly inside the set that has the Red, Green and Blue Guns mounted on it: it can be mis alaigned as a whole causing what you are discribing. Also, you have a mirror that relects the guns onto the back of your screen: less likely but it could be misaligned..
Just be carefull not to touch any of the following:
wires, circuits, circuit boards, heat sinks, and especially the three Big wires that go to the 3 picture tubses... they have high voltage
the heat sinks could also be live .. Just be carefull !
make sure you have really good lighting and room to work and you should be able to fix this without a problem.
Good Day, John;
It sounds like the Convergence IC's have poor solder connections, by re-soldering the convergence output IC's should solve your problem. The IC's are large and mounted to large silver "heat sink" with STK 392 # on them. Good Luck, big IRISH.
Good Day, Girl 1;
Hey, Girl 1, I have four girls not counting my wife . So, helping you may be difficult. Just kidding!
I would highly suspect that you have fluid on your TV's PCB's (printed circuit boards).
So, at this point that you should call an Authorized Service Center and have them give you an estimate before any repairs are performed.
If you want to try repair on your own e me at [email protected].
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.
you could be on the right track get some freeze spray and go around all the parts to see if you can make it act up, same with heatgun or hair dryer when first turned on heat one area at a time to narrow your problem down
You have a convergence problem, and the sooner you get the set into the shop the less it will cost you. It seems that you may only have bad or cold solder connections on the stk convergence ics. If you keep hitting it to fix it, its goingg to surge the parts then youll be looking at 300 bucks or more to repair. GET THAT SET IN ASAP. Good Luck
