Question about Jensen Q2749J 27" TV
Is your grey scale or Black and white programming pink?? Thats an indication that the green and blue grids on the picture tube are week or that the red is over driving. First thing is take off the back of the set. Find the end of the picture tube and look at the printed curcuit board there. see if you can find and red drive controls there. Put on a black and white pic and ever so slowly rock that red drive control a little at a time till the picture looks almost normal.. If you get it to be a little \less pink then stop right there but if it starts to get a bit green or blue then try rocking those controls all back and forth till you get the bese B&W picture you can BUT BE VERY CAREFULL as there is alot of voltage on this picture tube and if your not carefull it will bite ya. Now dont be too critical as the tube is a bit weak so you probably wont get a perfact grey scale so if after a while live with it or get a new set. Good Luck.
