Hi, anyone got any ideas about a HP D3857A monitor (5? yrs old?) which has only got the green gun in evidence? The owner said it had been exhibiting other stuck colours earlier but now it is solid green. Another monitor comes out fine so it seems to be a monitor fault.

I have tried tapping every circuit bd incl the crt board thinking it could be dry joints but I can't get it to blink at all. Also wiggled the video cable at both ends with no result. It has not been cramped up so it looks fine. Brightness/contrast and screen positioning controls work as expected. Video picture is fine.

Probably a tip job but just thought I would ask!

When you take it to the tip and throw it hard onto the concrete I would be interested to know if the screen smashed or not, I have chucked a few and to my astonishment the screen didn't even break.

It is not worth thinkng about really, but if you are really keen, take a look Here (http://pressf1.pcworld.co.nz/thread.jsp?forum=1&thread=26660&message=96639&q=FAQ+%233#96639) for further information. Unless you have electronic diagnostic skills and a suitable meter it is best consigned to the tip.

That is a sure test if it is a monitor fault, or a video card fault. When hurled forcibly onto concrete, a faulty monitor will bounce. But, dropped 5mm onto a cushion, a good monitor will explode into fragments.
Murphy had a phrase for it.

The screens are hard to break. Very hard. They are strong enough to withstand 14 psi. (somewhat over a ton for a 14" screen).

The neck is another matter. Not very hard to break those. Mono screens can show a nice circular sandblasted circle in the cenbtre of the screen with the right sort of fracture. :D (Colour screens are protected a bit by the shadow mask).

Forget the tip, turn it into a cool fish tank. (http://pressf1.pcworld.co.nz/thread.jsp?forum=1&thread=22545&message=64769&q=deceased#64769) ;-)
