My crt acer ac512 monitar only centre line view,c"not full view why?

there are several reasons why picture of crt monitors did not display good picture. if your monitor had horizontal line at the center of the screen?...the faulty is in the vertical deflection, check the vertical oscillator also the fusible resistors & capacitors around that section. if there had vertical line at the center of the screen?..check the horizontal deflection, horizontal output transistor also check the YOKE.

A vertical line has appeared just off of the center of the screen. I have unplugged turned off reset and changed the background but the line stayed.

The vertical lines means you have failing T-CON board, part of the LCD panel assembly, it will get worst, new LCD panel will be needed. Westinghouse uses cheaply made screen like CheiMai, not LG/Philips.

Black flickering line vertickally through monitor screen

It could be either of these:

You're monitor is dying and you need a replacement (Starlogic brand is notorious for dying early and giving poor performance)

You're graphics card is going out. If you have an extra monitor laying around, take out the Starlogic one and plug in the other to see if the same results occur, if not, it's the Starlogic monitor, if the problem still persists, you need a new graphics card or need to update your current drivers.
