Having problems with your Xerox XG-91D 19" LCD Monitor ?

I own a XG-91D monitor that the screen goes black after about 5 seconds. I found 2-470uF 25V capacitors on the power supply board that were leaky - replaced them but the problem still persists. There were 4-1000uF25V caps that looked and measured ok (using a capacitance checker). Any advice would be appreciated. Thanks, Tom

Hello,

Replace thee 1000uf caps too. A capacitor meter will not test the ESR ( equivalent series resistance ) of the caps the cap meter will show them to be good but an ESR meter will show then to be bad. Also be sure to use low ESR caps. If you use general purpose aps like from Radio Shack it can damage the board board because of the ESR rating. The temp rating needs to be 105c or the new caps will blow out within a month because of the heat in the monitor case ( No fans ).

I hope this helps, if so please rate our solution.

Lost my fuse + fuse cap for altec Lansing 621 during a move, does anyone know a place to get one and part #? I would assume they are still using the same fuse cap and fuse in most their other models so if you've had the same problem but with a different model please do tell, atleast it will give me a lead. I haven't yet hauled the subwoofer to radio shack but given their limited selection I doubt they would have what I'm looking for. Altec Lansing themselves have provided no help. Thanks a lot,

Blank Screen Viewsonic VG2230wm 22" monitor. For the last few weeks I have been noticing that when I turn the monitor on it would bllink and go out. When I turned the montitor off and on again it would work fine. Then while in the middle of working on my computer the screen went black. I noticed that the blue light was still on, I turned the monitor off and back on but the screen remains blank. I shut down the computer and the monitor and let them set for a few minutes then turned them back on.
