There's a very narrow line (white) appears at the very top of the screen when the picture scene is mostly black. A verticle adjustment should fix it but where is it?? RCA F36TF720


it may be an electrolytic cap problem as most newer sets are controlled by an I.C. chip for horiz and vert timing/size/linerity

Colors dont line up, black square,in middle


with no model or make, all i can suggest is that one of the convergence amplifiers is acting up(usually there are two used in most rear projection sets) they may have to be replace at the same time to avoid doing the same thing later on. look for a heavy metal heat dissipator tha is where they usually mount.

Wavy White and Grey lines then nothing


The Flyback transformer needs to be replaced on the Deflection Board. It has the big red wire coming out of it going to the picture tube. Becareful with that. Some of them hold a nasty charge waiting to bite someone. Wont kill ya, but it hurts.

Hi, your vertical section is beginning to fail, from your description you have a few electrolytic capacitors that are beginning to go bad, the correct term is they are "leaky", the set can be fixed easily by a tech, not so easy for a layperson because you don`t have the service manual or a capacitor analyzer. NOT an expensive fix, tech will have to remove board, unsolder some caps, check them and replace the bad ones, do a little touch up solder work and set is good as new, any questions? feel free to ask away, if not Happy Holidays, BMW Rider

Big black screen in picture


You have the CC (closed captioning) turned on and it is set to text mode. Look for a button on your remote labeled "CC" or go into your TV menu and make sure the captioning selection is set to "off".

Your closed captions are on and set to TEXT. Go into the menu, turn off the closed captions and the black box will vanish.

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
