The picture on the set is still crystal clear after looking much closer the set seems to have rolling horizontel lines and this gives every vertical line and edge a nothced appearance. The best way i know to describe it is the picture is clear but it is like looking through heat waves coming up off of hot blacktop.

SOURCE: 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

If your satellite is in the component jack and does not have the lines, you have a bad doubler or 2HD board. These boards are located in the metal container on the left side of the tv (left as in when you are looking at the back of the tv).

SOURCE: Lines horizonal - seems to be caused by voltage to green CRT

Your green CRT is shorted. To test put your red crt socket on the green and your red on the green. then try turning up red control if the green now works its not your tube. If the same thing happens with the red socket on the green you can be sure its the green CRT if the green works properly with the red socket, then you have a problem in the green drive circuit and not the CRT. hope this helps.

I believe the format, or FMT board is going bad. this is not a do it yourselfer type repair, unless you have extensive electronics background - I have one myself with the same problem. I am waiting to get a new FMT board for mine.

the DM and/or the FMT board are going bad. the chassis needs to be rebuilt. check out www.tv-techs.com
