I have a mitsubishi 55in big sreen hd 1080 medallion tv . now and then the sreen at the top will get a black bar acrossed it if i slightly hit on the top the full picter will come back in please help.

I would try the reset button in the front. Unplug the set push the reset and plug it back in.

0045,0041,0044,0049,0046. Try these codes first. For more information http://electrohelponline.blogspot.com/

More likely the cables from the Direct TV box and the TV are incorrectly connected. My guess is that you have red, green, and blue cables that carry to video signal and they are incorrectly connected or one of the cables is bad.

The model indicated here is not designed for hookup with a laptop or computer at all.

Some of the older Mitsubishi with HD 1080 have only one component input for HD---it is marked on rear as DTV----also a model number may allow me to give another suggestion--Some of these sets (ws, wt, vs models) will on occasion lock out or disable the input/s.

Depending on model number most also have 3 hidden menus---one is the option menu----it allows with the Mitsubishi remote via a 4 digit number (by model number) to enter there and do a hard reset of the set----sets every setting back to factory original---seen it "cure" all kinds of odd problems from missing rear inputs, no sound, odd video issues---you name it.

Get me the model number and I will see if can find the code for yours--you can also try hooking first direct a 1080 blue ray or Dvd if you want to see if the input is active or not first.

Watching the Masters and the top part of the tv the color went out it shows green and purple and top half shows double vision...

Yes,U know how to solders?Ur convergence it dead,must replaced it with a convergence kit,use what in that kit.Tries these websites for the convergence kit.Tv repair World.com,Tv repair Kits.

Are you sure its the right remote? Verify TV mode on remote if equiped with mode switch. Drain the remote by removing batteries.

it is usually in the Audio settings,sometimes by the CC settings, if you go to the TV and enter th menu from the set, go thru one at a time until you find the spot to turn it off, it is under options or Menu on the remote also, there maybe an SAP Option on the remote itself, but you may have to press another key first like a "Function: Key.
I hope this helps some, if so please give me a good (fixya) rating. Thanks and have a Blessed Day

i have a green screen on my mitsubishi medallion hdtv 1080
