Question about Westinghouse L1975NW Monitor

1 Answer

Image blinks off after about 1 second after being powered up. Cut the power off at monitor, then turn back on and it repeats. Full image from computer shows up for about 1 second then disappears. The problem would be corrected at first by turning the monitor off/on several times. Now it just continues to do this no matter how many times you turn off/on. I have a L1975NW Westinghouse 19" Widescreen monitor.

If you are going to DIY and have proper tools and know safety precaution then please read on:
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply (they should be replaced in a set), blown fuses; poor solder joints, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed monitors to get some ideas what to look for: http://s807.photobucket.com/home/budm/allalbums
Post back what you see inside so we can guide you further and it will help out other people in the future also.

Samsung syncmaster 2220 blinking blue light and no image display


Here's some tricks I would try...
1. Verify the monitor's power cord is plugged firmly into the wall outlet and the back of the monitor.
2. Verify the monitor cable is firmly connected to the computer and the monitor.
3. Verify that you have turned the monitor power switch on.
4. If the power light on the monitor is not on, test the wall outlet (plug in a light or something you know works).
5. If the power light on the monitor is not on, try a different power cord.
6. If the power light is on and yellow or orange or flashing, but nothing displays, or the display is incorrect, borrow a monitor from a friend. If that works, your monitor probably needs replaced.
7. Also, you could try your display on a friend's computer. If it doesn't work, your monitor probably needs replaced. If it works properly on your friends computer, the problem may be with your computers video output port, motherboard video chip (or video card, if you have one), or drivers.

Good luck.

When I power the Dell AS500 Monitor on, it flashes for a brief second then goes blank but the power switch keeps blinking. The monitor does not function but I do get sound


Check and see if you see a faint image in the back. If you see it, then the backlight has failed. If you cannot see any image, then the power supply on the monitor has failed. You should contact Dell to see if the monitor is covered under warranty in either case as you have a faulty monitor.

More likely to have failing power supply problem due to bad caps, look for caps with bulging top first and post back what you see inside, see example of failed monitors due to bad caps: http://s807.photobucket.com/home/budm/allalbums

Your Monitor has a heat sink issue. A capacitor in the monitor is at fault and when it heats it tells the monitor to turn off the display to save the display from damage....Problem Cost to repair will supercede the cost to replace it...Wal-mart 15" monitor 119bucks --17" monitor 129...same at staples office supply (Poof) problem solved.

Monitor image comes up, then blacks out, power still on


Hello David,

This is very common problem and is heat/age related, but It can happen to monitors that are no more than a year old. It is usually bad capacitors on on power inverter board. I just fixed two monitors with this problem. This problem is common across all brands. Look for several radial capacitors in a cluster on the power inverter board. If some are bulging or have a slightly domed top, they are the ones that are bad. I usually replace all the capacitors in this small cluster because some may be marginal. This is easy to do if you have a bit of electronics skill.

Syncmaster 910t blinks image perfectly once and goes back to black


I found a site that sells your (our) part: samsungparts.co. Look up that model number for the power supply under "Part #" and it seems to run about $60-70. I'm probably going to order one and give it a shot as a drop in replacement.

Nothing on the screen after power on


Turn on the computer and complete the following steps: Step 1: Check cable connections (If you can see the initial HP or Compaq logo screen but later lose the picture, you can skip to Step 2.) check the video cable connection on the back of the computer and on the monitor. Make sure that it is connected properly and the connecting screws are tight. Turn the monitor off and then back on again (while the computer is on) to see if an image appears. Some Flat Panel monitors have two similar power input connections placed side-by-side on the back of the monitor, which sometimes allows them to get confused for one another. One connector is used to supply power to the speakers with a separate power cord, while the other connector is used for the monitor's power adapter. Ensure that you have the monitor's power adapter cord plugged into the power connector and not the speaker connector. After you have reconnected the power cord, turn on the monitor (while the computer is on) to see if an image appears. If there is still no image, continue to the next Step. Step 2: Resetting the monitor At first setup, or under certain signal conditions, the monitor may not be able to switch to a new display resolution. Do NOT shut down or restart the computer. Instead, perform the following steps: Turn off the monitor using the Power button on the front. If the Power button does not respond, unplug the power cord from the back of monitor and wait five seconds. Plug the power cord back in. You should see the image from the computer on the screen.
