Sharp 28JW73H Green tint with lines across screen

When I switched my TV on this morning there was a green tint and green lines across the screen. The TV was in perfect working order last night. I am at a bit of a loss. The TV is about 5 years old and I'm not sure whether to replace or repair. I'll have a go at repair if one is possible but dont know where to start. Help!

    It is a Sharp 28JW73H TV. It has now developed a red tint as well.

    sorry for confusion

    looks like i need to go for the drastic option. No change when adjusting brightness and contrast. Got the back off. Just need an idea of what the screen voltage adjust looks like.

    Thanks

    Possible CRT issue = vary the brightness and contrast

    from min to max and see if the color changes---------



    A more dramatic test is = remove the back of the tv , locate

    the screen voltage adjust on the HV transformer and slightly

    turn ccw or cw and notice any change......



    let me know.................T.

    Usually on the body of the HV transformer, the part with the

    lead going to the CRT................T.

Green vertical lines across the screen.


Green lines on LCD screens generally means physical damage. Did you drop it or bump it by chance? Physical could also include the cable that you are using. Try using a different cable, or make sure it is connected all the way.

Green horizontal lines across screen


try adjusting the green screen control. remove the front bottom panel of the tv by removing any screws holding it in place. gently pull of the front panel, there are gromets holding it in place, you will be able to gently remove the front, just make sure you get all those screws. now reove the small wodden or plastioc panel. now you will see the screen/focus assy. check to see of the screen controls are the top 3 or bottom 3. adjusted the center screen it's the green one, the other 2 are the red & blue. it is best to adjust in a dark room where the lines will show up easier. good luck
