The Westinghouse L1975NW monitors seem to have a common failure point and this Instructable will show you have to repair this problem. If your monitor has either a blinking power LED or no power at all then this should be the solution to get it back up and running. To complete this repair you will need the following:
Tools:Phillips screwdriver, flat blade screwdriver, soldering iron, de-solder braid and a pair of tweezers.
Parts: Qty 2 40T03GP MOSFET, Qty 2 220mf 25v capacitor, 1 4amp pico fuse (surface mount)
We have a kit of all parts needed on our web site http://www.ccl-la.com/catalog/product_info.php?cPath=21_35&products_id=28
If you don't have a monitor to repair check Ebay.com, you will find them for sale usually for less than $30 in as-is condition, just be sure the screen is not cracked.
This repair guide also works for the Acer AL1916 and the Gateway Gateway FPD-1830 as these are the same monitor on the inside.
