Greetings all. My problem is that about 3 months ago I started noticing green arching lines that started in the lower left hand corner, peaked in the middle of the screen and came back down to the lower right hand corner. As the tv was on longer the lines would get darker and more defined. Then about 3 weeks ago I turned on the tv and after about 5 min. the screen started to flash green and the picture went out. Now if I power it up, it stays on for about 30 to 40 seconds and it starts to flash until it turns itself off. I had sears take a look at it and they said that the green crt needs replacing. After reading some other problems on the site, there was some talk about adjusting some screws behind the front panel.? Was just wondering if any one has any idea what the problem is and if i could fix it and save myself $600.00? Thanks for listening!
Yes there is a small black box with 6 controls on it, take off the bottom front of the tv, behind that you should find a black piece of plastic you can remove by taking out 2 more screws. the black box should be in the upper rhs.now i don't remember if the top 3 are the screen controls or the focus controls. the rows should be labled, you are looking for the screen control row. the green control is the middle one. you can try turning down the control till you no longer see the green lines. try adjusting in a dark room, it will be easier to see the lines & when they are gone. if you problem is not solved by trying this, then i agree with your tech & the green tube is bad. good luck.
