My Xerox XG-91D LCD Monitor start, display briefly (about 1 or 2 secs) then goes back. any solution in this case? mention that i use with a dvi-i adaptor on a vga graphic card. thx

Try a new cable. If any of the pins is slightly bent the monitor will not receive the correct signal to display. I would recommend a new cable even if you don'y see anything wrong with the old one.

You may also have to check the IC/Transistors Inverter transfomer drivers, also should Ohm out the resistance of the transformers.

You need DVI to VGA adapter: http://www.google.com/products?sourceid=navclient&q=dvi+to+vga+adapter+radio+shack&um=1&ie=UTF-8&ei=5hODS7HvJIausgPJq629Dw&sa=X&oi=product_result_group&ct=title&resnum=3&ved=0CCEQrQQwAg

This is most likely the power inverter board in the monitor - this is common in many monitors. If it started taking longer and longer to display an image, and the power light is blinking on-and-off, that's the problem. You can confirm that it's the monitor and not your computer or the cable by plugging in another monitor if you have one to try.

If it's under warranty, send it back, if not, there are inverter boards for many common models of LCD monitors that are replaceable. The board can run anywhere from $50 on up. Depending on how old it is, you may find it better to just replace it with a gently used one from ebay.

Yes. if the macbook has DVI out. Do you have the correct adapter? DVI, you can't use the VGA adapter, you need the appel DVI out adapter.

If you look on the back of the monitor it has the name of the manufacturer - which I googled and found this warranty information: http://www.sylvania-displays.com/Support/warranty.html
