Westinghouse LCM 20v5 20.1 inch LCD monitor

My monitor keeps shutting off when I try to turn it on. It makes a weird buz sound then shuts off, it will come back on and stay on when I turn it on and then back off a few times. Maybe a power supply problem?

Next time you get it running, right click my computer>properties>hardware tab>device manager and look for your monitor on the 'Monitors' '+' sign and right click>delete. Also check 'Display adapter' see if the correct driver is displayed. Re- boot and let Windows re-install monitor driver(it should list it as 'Sony')

When the screen turns black again take a flashlight and shine it in the bottom left hand corner where the Windows Start button is located. If you can see a faint image then your back light is failing. If that?s not the case the next step would be to attach another monitor to your computer to see if the problem disappears. If it does that points to the monitor, if it doesn?t then we need to take a look at the computer itself. Let us know what you find out and please don?t forget to rate this posting.

Probably 1280 x 1024 at 32bit color depth assuming those are the settings you are asking about. If not, please be more specific with a follow up post.

SOURCE: Power of the Monitor keeps going out.

You need to look inside your pc and check and see if the video card is plugged in tight. Sometimes if it is loose, and it isnt connected, and causes the monitor to not show any picture, but still has power.

How do I convert a Westinghouse 22" LCM-22w3 DVI/VGA LCD Monitor into an HDTV?


Dear Amy,

Normally, monitors do not have tuning electronics for capturing TV signals.
Therefore, consider the monitor as a "dumb" unit that only displays information coming from your computer. Also, this unit does not have a HDMI input, but only VGA.
So, you are fated to have this monitor connected to your computer, always.
Now, you may find good software that will "tune" the TV signals from streaming at the Internet and show whatever is being broadcast. The same way you can access YouTube and watch videos these TV tuners will get the streaming signals the TV stations send via Internet (not all do that) and watch the channel in your PC/monitor
Since I do not have additional information about the computer you use I cannot give you other ideas
I hope I have helped you.

Can a westinghouse lcm-22w3 be used as a tv


Yes, you will just need to have the right output on your cable box with some conversion. (eg. if you have RGB out of the back of the box you will have to get a break out cable that goes from that to VGA for the back of your monitor.

Not turning on


Check the capacitors on the power supply board in the unit. This is a very common problem with this unit but it is easy to repair. Here is a link to a repair guide that shows how to open the monitor and what to look for.

I have a 17" LCD Monitor - LCM-17V8. When I turn


Hi, it seems to be an issue with your monitor's backlight not working properly. Just to be sure, try using a different monitor on the same exit of your VGA, if that works, my supposition is confirmed. In case your monitor is still under warranty, just send it to Westinghouse support center, otherwise I'm afraid you will have to buy a new one. Hope it helped, Franz

After pressing the power on button it starts to turn on but then makes a hissing sound and goes into standby mode. It takes several attempts before the screen wont make the hissing sound and finally stays...


Hello,

You have a monitor with a failing power supply. The Viewsonic VG2021M monitor uses the DAC-12M033 power supply board. After several years of use the capacitors in the power supply start failing and not keeping a charge. The capacitors are on the output side of the power supply and help filter and stabilize the voltages. When they fail the power does not settle when you turn it on so you have to do the on/off/on/off to get it to start. If you can solder then you should be able to repair your monitor. Check out the article on our site at: http://www.ccl-la.com/blog/index.php/repairing-the-westinghouse-lcm-20v5/ it is for the Westinghouse LCM-20V5 but they both use the same board so the repair information is the same. If you don't want to do the repair yourself we do offer a repair service for this unit, it runs $32 plus shipping. You can get more information on this service here:

My monitor will not shut down - screen stays white


You got a short circuit in one transistor located at the inverter area. The transistor is acting like a conductor and not shutting down the power to the back light inverter. If you are a technician and want to fix it, look for short circuits in transistors.

Good luck.

Make sure that all three screws are removed from the back of the display. This is in addition to the four that hold the stand on.

Westinghouse LCM-19W4


I had the same problem with my two LCM-19W4 monitors. Both failed within two months of each other. Radio Shack stocks 220uF 35V capacitors that work fine for this. You have to pay $1.49 ea though.
