hi all

check this out...

i'm using two monitors on my pc, my secondary monitor is actually an old one i had which was disused when i bought a new bigger flatscreen one...

now that i've moved out of my crammed little apartment, i have space to have my two monitors side by side creating an extended desktop

the thing:

there was a reason for which i bought my new monitor, the old one has a "slight" problem where the image constantly flickers with horizontal lines and distorts the top and bottom of the screen, stretching and squeezing incessantly

this display of erratic behaviour culminates in a point where all the image in the screen has become no more than a series of horizontal lines

the slightest vibration on the desk can trigger this phenomenon, and the monitor has to be positioned in very precise angles to display proper images... i usually have to wedge an object under the monitor to keep it a bit tilted... it seems to work to some extent... the monitor gets used to the new position after some time and craps out again...

pounding on it senseless tapping the monitor on the side also works to some extent, but it usually snaps back to a completely distorted screen..

anyone have a clue about this??

i would like to try something constructive on it before i set it on fire send it for repairs

it's either a faulty component inside the monitor, or most likely, from the symtoms you describe, it's a broken solder joint on the monitors mainboard. The solder joints frequently break because the mainboard is on the base of the monitor where the full weight of the apparatus is often not adequately supported by plastic parts. Better monitors tend to have metal load bearing supporting parts. Plastic supports, in time, tend to distort, causing the mainboard to bend and break solder joints.

That's why you can fiddle it into a position where it will sometimes work, but only when the dodgy solder joint is in contact.

Messing around in there could possibly KILL you if you have a weak heart and you get  a shock, so, best to get a daredevil or a qualified technician to repair the damage......... better yet, seek out a second hand replacement, they are usually cheap.
