Vertical white lines appear on the screen. Samsung provides the following information but doesn't say what circuitry they are referring to. Samsung says: DLP TV: I Have Vertical White Lines...


That answer I agree makes no sense.

Most of these sets have NO vertical hold and if did it will not cause the lines.

A brief educated guess:

Set has a main board that communicates and controls the screen--tests for that are not simple (checking waveforms with a scope and signal generator).

The model indicated here is a DLP that uses a lamp (let me know if model listed is not the one you have).

In DLP sets aside from main/digital board you also have a optical light engine---it processes all signal in and out to the screen.

Optical engines do fail and cause some simple and some complicated picture issues.

Some will even cause the set to "lock up" with a picture or strange looking screen---clue to this is you have to shut the set off by pulling the power cord.

The set may be old enough they do not really want to help you or even talk about it.

How do you adjust the vertical hold on this TV?


Modern TV's haven't got a vertical hold control like in the old days. The TV system now uses a system of counting. For instance;
UK is 625line which is 15.625KHz line frequency. Divide it down by the correct amount and we get 50Hz frame frequency. There is no need for external controls. That is how copycode on video works. Supply 620 lines and in the end that is not divisable to give 50Hz so video cannot be copied as TV shows the wrong speed frame and will cause no colour and picture disturbance.
Likewise the same rule applies to USA 60Hz system.

Continuous vertical roll on tv


Wow 5 months without a solution. NOT GOOD.. Well I hope I can help...
This sounds like a vertical hold problem, and is normally easy to fix.... There should be a couple of nob's on the lower back of the TV. One for vertical and one for Horizontal hold. You need to find the vertical hold nob and adjust it, until the rolling stops and stabilizes. If however these nob's are not visible you will have to take TV to an engineer to fix it.
Hope this helps..

How do adjust verticle picture on Hitachi 46F510


You can adjust vertical height through the service menu, but i would recomed that you trouble shoot the vertical section as its probably a solder joint , leaky diode or something that is causing the problem. Often its bad solder at the vertical output IC itself that causes that sympton.

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
