Vertical band on new monitor

HI
Before getting a new tv set I would try all cables and contacts, as well as looking in the troubleshooting section in the manual.
hope you succeed

Xerox XG 91D 19 in Flat Panel LCD Monitor

This appears to be a common complaint on LCD monitors. Some LCD screens have control issues.
An LCD screen is the panel and a bunch of Line control chips wrapped around the outer edge. A problem with one line top to bottom or left to right is almost ALWAYS the LCD panel itself.
A problem with a fixed band (The band is in the same place at any resolution) is often the LCD but might be the signal driver chip (A large plastic pack with about 100+ leads). A person with a VERY small soldering iron might be able to resolder it, but they MUST know what they are doing. (board must be heated, lead free solder, eye like an eagle...)
If the band moves around or changes width, it is the signal chip or the power supply to it from the power board.
It can be software if there is a firmware upgrade. This takes a shop.

Check power supply section for bad caps with bulging top first, may be a sign of failing power supply: http://s807.photobucket.com/albums/yy352/budm/Viewsonic%20VX2235W/

It is the problem of monitor pcb in vertical section.check vertical ic for dry soldring. Resolder the ic if problem still on then change ic or check components related ith it. check continuity of vertical deflection coil.
Hope this be of initial help/idea. Pls post back as requested, how things turned up or should you need additional information.
Good luck and kind regards.
Thank you for using FIXYA.

what is the solution for this? my husband just turned his pc on when we got home and there are line blue lines running up n down in the black

This is due to vertical section failure. Change the vertical supply rectifier diode and supply filters. Then check zener diode leakage in pumpup circuit section. Also check any electrolytic capacitors leakage in vertical section. If it is old model tv change vertical height, vertical lenearity presets also. I hope given details useful to you.

Hello, one of possible solutions is to replace capacitors (10uF/50V) on HYPER (PD0246) module. Please ask the tech to check/replace them. If you need more info please advice.
