Kv-35xbr48 turns on fine nice picture then horizontal lines form distorting picture like interference also is the back hard to take off and put on needs a good vacum thanks for any suggestion


At first the picture is ok, and then distorted with horizontal lines i thinks. If the horzontal lines are parellel acros the screen, with an inch apart across the whole screen, your tv needs screen adjustments. Screen voltage may be high. look into the crt base also. Change it first. These also not resolve the problem, LOT may be faulty, with respect to screen focus pack. May need replacement. Try first setting screen voltage to a lower settings and observe.

Picture Problem


In that set its usually a bad picture tube. The lines you are seeing are called retrace lines. You can take it to a shop and they may be able to rejuvenate the tube

32Inch Flat Screen SDTV - with picture distortion


If you have a TV shop at all any more in your area, any tech working on them will know where to look. This is a pretty common problem although you are getting it too early.
Since it will require a certain type of instrument (capacitance meter) to verify the problem part, I don't want to go into detail concerning a 'do-it-yourself' repair since it may be a little difficult to order these in single quantities and a decent shop should have the right value on hand.

It shouldn't cost too much.

Black horizontal lines across bottom 1/3 of screen


This is due to vertical section failure. Change the vertical supply rectifier diode and supply filters. Then check zener diode leakage in pumpup circuit section. Also check any electrolytic capacitors leakage in vertical section. If it is old model tv change vertical height, vertical lenearity presets also. I hope given details useful to you.

Top of the screen Picture Problem


sound like you have 1 or a couple of leaky/bad capacitors in the tv's vertical circuit, typically, there sould be 5 to 10 caps. in all, but you just need 1 bad one to cause your problem. good luck.

One thing you should not do with electronic devices which have a start up proceedure is to turn the power off, and then on again without a wait of about five minutes. Some equipment manuals warn you about this, and specify a longer period. The start-up has to have time to reset. It will be more likely to reset if you do not leave it on standby, and even unplug it. In your TVs case you need to describe the distorted picture as it may give a clue to a fault, or incorrect start-up. The horizontal line indicates the frame timebase had stopped working. No picture could be a fuse blown inside the set, or a timed cutout which may reset after a time. Try after several hours to see if it comes on. If it is just the frame timebase (vertical) it is worth repairing.

Green screen with almost horizontal zigzag lines


Is good that you hit it and it reacts,very likely you have loose conections in different places but for the distorted picture you need to check the horizontal driver transformer and flyback after that is corrected you need to check the complete chassis for loose conections.Take your time.Good luck.
