Question about Westinghouse L1975NW Monitor

1 Answer

No display Same problem here, working fine up to lunch, after lunch, nothing, green lite is on, no display. Plugged in an old CRT and display is there. Seems to be a very common failure with this model. My next monitor will not be a Westinghouse.

    Fix found. The monitor was working just the back light was out. Use a VERY bright light shining in at an angle to see if you can see an image, if so then you have the same problem. If you are not an electronic technician I suggest you find one to make these repairs for you. The problem is a blown fuse on the power supply board and a bad capacitor. Look for a cap with a bulged top, (they should be flat or concave) I had to replace a 220 microfarad cap 25volts, and a fuse on the bottom of the board. The fuse is a SMD (surface mount device) and is soldered to the board, not a plug in or easy to replace part. Fuse is marked with a "S" and is next to a zero ohm resistor marked with a "0" Best info I could find is the S is code for 4 amp on the fuse. High voltage is on the board, keep away if you don't know what you are doing.!!

There are fuses in the unit but why did they go bad? something else has to go bad to cause the fuse to blow, unless the fuse got old or had bad connections at the fuse holder. Can try a new fuse then run and see if it works. Just don't run it empty, just put a container of water in it to test. If it works check all connections and see if any are loose or browned like it has been hot. That's where your problem will be.

CRT Monitor Displays only a thin bright horizontal line


Vertical IC loose connection. Best is to reflux it or resolder. It is in internal circuitry inside the monitor commonly an upside single line IC.

And its a minor repair only. But I recommend it to be serviced by a qualified technician. Inside it are plenty of nasty voltages. It might caught you.

Envision EN7410e monitor


Just fixed mine. Maybe it's a few years late. Hope you guys still have the display. It's the power supply board. I've just replaced 4 bulge capacitors near one edge of the PS. They are 2x1000uF 10V, 1x470uF 25V & 1x470 10V. I salvaged my parts from an old CRT monitor. Hey you can go green with your repairs too!

Latitude C640 is dead!!


The only solution that I can think of would be a power jack problem. I would not advise replacing the power jack yourself since you have to take out the laptop mother board, de-solder the power jack then solder the new one on and put it back together. My advice would be to take it to a professional computer repair shop and have them take a look at it and replace the power jack. It is worth getting repaired since power jacks usually range $40-$70.
