Picture bottom half only


Hello Gordon ok the problem that your tv set is having is coming from the vertical circuit which either is defective or has a faulty IC vertical amplifier, lets try something tap the side of the tv set if the picture goes back to normal than this is bad soldering on that circuit if not than the problem lies in a component that is defective and has to be replaced.What i would suggest is to have a tech come out and service your tv set this is not an expensive repair most of the time it is just bad soldering on the vertical deflection circuit and this could be repaired in minutes thank you hope this helps.

Sound but no picture


This could be a problem in the vertical sweep circuit, as when the vertical circuit fails, The video or screen will blank out so the picture tubes do not get damaged. In this chassis, I have seen the convergence IC's cause this, or the capacitor in the sweep power supply that feeds the voltage to the vertical IC has failed and blew out the vertical output IC. If you have no solid state repair experience, play it safe and call in a trained tech to assist you in this repair. Good Luck.

Vertical lines that scoll the screen picture.


Ok this problem is coming from either your tv sets vertical circuit or the tuner itself is faulty, most likely the problem is coming from your vertical circuit with bad solder on the vertical ic or you have a faulty capacitor which can also cause this problem what i would suggest unless you have electronic experience on troubleshooting electronic components is to take it to near by tv repair shop and have then troubleshoot this circuit to see which component is giving you this problem, thank you,hope this helps.

Mitsubishi WD-62825 vertical lines, blue snow, picture jumping


I have the same problem with my tv, my tv tech said mitsubishi knows of the problem and knows how to fix it, but it would cost me 700.00 plus his labor to take out the chassis and send it in to mitsubishi, plus I would be without a tv for up to a month. this is b.s.

NO PICTURE


sounds like the vertical output is causing the CRTs to shutdown for protection. Try resoldering the vertical output IC that will often correct the problem. If not the vertical output IC may be defective.

Toshiba TV with only a horizontal picture?


You could have a simple loose connection on the vertical output IC . Sometimes you can tap the board and the picture will fill out . Or the IC could have failed . It will also take out the resistor that supplys the voltage to the vertical IC . If you take it apart to work on be careful as you can be shocked if you don't know what your doing . Most repair shops charge $50 to $80 to repair . 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
