First, I must write that LETHAL VOLTAGES exist in the monitor years aften being unplugged.
If you go inside and kill yourself, you were warned and can't complain to me about it. (Love that sentance!)
The issue of arcing in TeleVisions (TVs) has been around for decades. It's usually as you suspect the buildup of dust or some conductive path that breaks down once in awhile. A good TV shop tech would know where to look and could clean the path up to give the TV/Monitor a few more months of service. But once the arcing starts, the pathways are laid down and the carbon that is deposited sets the eventual failure into an inevitable event.
Best of luck,
I've had a Sylvania F90 19" monitor for about 5 or 6 years now, without any problems until this past month. Occasionally, a loud SNAP will will come from the monitor, and the screen will "jump" at the same time. Lately, the snapping sound has become very frequent, sometimes happening 7 or 8 times in quick succession! When this happens, I shut down the computer ASAP.
I asked a friend about this, and he suggested that I take the cover off and blow the dirt out. I removed the plastic cover and used some compressed air, but did not try to remove the metal shielding covering the components (and I won't remove it!). My friend said that a part might be going bad inside the unit.
Does anyone have any idea what might be happening to my monitor? I'd like to have some idea what is going on before I cart it off to a repair shop with no knowledge of the possibilites before I take it there.
Thank you in advance!
