If the double image is in a differant color, then its your convergence IC's that need replacement. This is not a job for the unexperienced person. If you have no electronic repair experience, please seek out a pro to assist you in this repair. There are two IC's, about 3"X5" that are black in color and have STK with several numbers following them. Good Luck PS please dont forget to rate this thread.

Thin red line across screen two inches for the top. Picture above line is good, picture below line has no color and double image.
Hello,

IF YOU HAVE A SOLID BLACK LINE RUNNING VERTICALLY THEN YOU HAVE A FAULTY MATRIX INVERTER. IF CENTRAL THE MAIN VERTICAL INVERTER NEEDS CHANGED. LEFT = LEFT VERTICAL INVERTER RIGHT=RIGHT.........

ANOTHER WAY TO GET THIS FAULT IS WORN OR DAMAGED RIBBON/PLASTIC GOING FROM THE SCREEN MATRIX TO THE INVERTER

Hope this will help out.....

I cant stop the tv monitor screen from jumping it has something with the dvr
Hello What type of TV do you have, analog or digital? If you have an analog TV and the screen is rolling it is the vertical hold. Because the vertical hold operate on 60 cycle which the same as AC line cycle. The 60 cycle in the vertical hold is as a oscillator or timing circuit. When the TV pick up the image for the NV devise, they just don't mix. Why, because image intensifier tube in the NV devise is operation at 25 to 50K Hz or cycles. The vertical hold circuit pick up on the 50K Hz signal which mixes with 60 cycle timing circuit causing the screen to rolling with lines across the screen @ 60 cycles. Digital camera and digital camcorder with digital TV will help, or a image inverter that takes this 50k Hz signal and covert it to some that analog TVs can use. GB...stewbison

TV TURNS ON,LINES ACROSS SCREEN THEN TURNS OFF BY ITSELF
sounds like a vertical problem, usually you'll see one white line across the screen, but one I worked on would come on and the bottom half of the picture was gone and there were lines across the top of the screen.

If you know how to solder & can find the vertical output chip then you could try resoldering the pins. If this doesn't fix it then it needs new parts.

Sony KF50WE610 Vertical Blue Lines Across Screen
the vertical blue lines indicate some interference from other electronic gadgets near your tv. it started showing up on my sony grand wega when i installed my wireless modem. i almost ordered a new rear projection lamp costing over $100 but decided to experiment. i first moved my desk computer farther away from the tv then isolated the wireless modem router by placing it inside a small glass - the vertical blue lines became lighter in color so i dedided to find another small glass that fit inside the first glass container then put the router in the double glass - no more blue lines and my wireless modem router still works.
do some deductive thinking to figure out what's messing up your tv and isolate the interference.
good luck!

Vertical hold circuit is failing.

Check capicitor in vertical hold circuit. You should have solid knowledge of electronics repair before attemping repair. TV's can emmit harmful radiation, and produce voltages up to or in excess of 30kV.

Verticle hold transistor?
The vertical hold keeps a normal picture from rolling either up or down. You don't have a normal picture (raster) here.

The problem you are having is a vertical deflection problem. The screen is being compressed to a thin white line. It's probably a defective vertical output module or transistor. This part is not too expensive. Less likely would be a vertical deflection coil, which would be more expensive because its usually glued to the picture tube and harder to replace.

Good Luck!

Picture has horiz. lines
There is no vertical hold in the tv circuits now adays. You may find a vertical center or a vertical height. Your problem sounds like (if it has PIP Thats Picture in Picture) its in the PIP module and its a small module that stands up and most models of Mistubishi this module is no longer availabvle. The problem with the module is the small pana caps are leaking and ruins the PC traces. I have heard that theres a kit available on E-Bay to jump out this module. Now if its not the PIP model then it could be a few capacitors in the vertical sweep circuit. Also the B+ feed off the Flyback that supplies voltage to the vertical output IC could have a bad or leaky capacitor in the circuit. If your not a tech or solid state troubleshooter theres not much you can do and SHOULD take this set in to a repair center. Good Luck

Ours is a Mitsubishi Model#VS-55705 purchased in October 1999. It's a 55" rear projection t.v.. The problem we are having is that when we turn the set on - we have black parallel lines rolling down the screen. When it initally started this would happen only until the set warmed up. Now it lasts for 3 to 4 hours after turning on and will occasionally start doing it after viewing for awhile. Otherwise the picture clarity and color are fine. Any suggestions as to what is wrong with it? how much it will cost for me to fix it?

When we first start watching the piture is clear and everything functions properly. Now there are redlines that move verticaly through the picture, getting progressivly worse. The first time this happened the TV actually turned off and would not turn back on. We unplugged it for about a week, and tried it again. This time the picture lasted less before the red lines appeared. At that point we turned it off and unplugged it. Any ideas with these symptoms?
