When CRT TV's show only a white/bright line horizonatlly It is a failure of the flyback Transformer. Not all that costly to repair. Your old TV will probably still be working when all the latest plasmas and rear projections have been laid to rest. Fancy junk TV's dont get any better programs than those old reliable ones
May have burned CRT(s), (if you are not talking about convergence.) Burned CRT shows when that CRT (R,G,orB), does not show in an area of the screen where it should. Check bright white color = full R, G, and B CRT brightness. Gray = mid RGB brightness. Yellow = R+G(no B), Blue-green = B+G, no R, etc.
yes! those are the screen and focus adjustments. 3 for screen, 3 for focus. try this. go in menu....turn down color, brightness, contrast all they way down. you should then have no picture, but in your case a little red. then go to back of tv and turn those 3 screen adjustments all the way down. slowly turn the screens back up until you get barely a picture. because remember, your brightness and contrast is all the way down. the picture should be dim but seeable and with red, green, blue adjustments, make it a black and white picture. when balanced..... turn up color , brightness, contrast in menu. enjoy!
You can carefully remove the rear top cover ( make sure it's unplugged) and carefully wipe the dust off the projection lenses and mirror and inside screen and stay away from the electronics and capacitors.Years of dust build up can blur the picture and give it a glarey picture.
