Westinghouse lcm 19w4 has to be used in brightest mode or
My monitor that is a couple of years old has bright bars that run up and down the screen kind of like the old tvs use to do when the vsync was out of focus, if I put it on the brightest setting the bars are unseeable, is there a fix for this?
Re: westinghouse lcm 19w4 has to be used in brightest...
I had this same problem and going through the on-screen menus I found a reset option. I reset the monitor settings and the scrolling bars went away. I plan to leave it powered up for a while to see if they come back.

It's mostly likely a bad capacitor in the main power supply of your monitor. If you're brave enough to dismantle it, look for capacitors that're "crowned", and sometimes even rupture from overheating in such circumstances. You can order replacements from Digi-Key if you can figure out which might be your problem, but I'm not sure I recommend you try this unless you have at least SOME soldering/desoldering skills or a friend who does. You COULD wind up worse off. It's up to you, only YOU know your personal skill level for such tasks. And do I need to say, UNPLUG it before dismantiling? :)
If the monitor turns on and goes directly to sleep, or it powers on briefly and shows an image then goes black then the monitor is defective. The first is often an I/O panel issue inside of the monitor. The second is typically a lamp failure within the monitor.
A simple test would be to plug a different monitor into your computer or this monitor into another computer. If the monitor doesn't work on another computer or a different monitor works on the same computer then the monitor is the issue.
If the different monitor does not work on the same computer or this monitor does work on a different computer then something on the computer is to be suspected such as a driver issue or a faulty video card.
If you find the monitor is defective then you should dispose of it (assuming it is not under warranty) at a nearby recycling center and purchase a new monitor. I would suggest something by Acer, Samsung, Dell, HP, NEC, or Viewsonic. These brands cost a bit more, but have much better track records.
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, 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. http://en.wikipedia.org/wiki/Capacitor_plague http://www.badcaps.net
This is a classic symptom of a failing power supply. There are parts called capacitors in the power board that will start failing and not filtering the power correctly. The regulators on the power board will not work until the power is filtered correctly and when you keep powering it on and off it fill finally start and run until you power it off, then you have to start over again. We have a step by step repair guide posted in an article on our web site at: http://www.ccl-la.com/blog/index.php/repairing-the-westinghouse-lcm-20v5/ This model is a little different from yours but the power supply parts are the same. If you have any additional questions just ask.

Hi Well that's the age old question. Is it worth repair? The problem is probably 6 capacitors in the power supply that have aged significantly. In my shop those caps would run approx $2.00 each with a total labor charge of $50.00. Now whats the charge where you live? Then you can decide if it's worth a $62.00 repair or a new monitor for $150.00. Good luck
in the safe mode you have to change the resoulution and the frequency to 60 hz you can get it by fright click on the screen and then choose properties and then choose settings and adjust the resolution to 1280 to 800 and then choose advanced then choose monitor then choose the frecuancy to 60 hz ok and apply ok and insa every thing will be ok conntact me for more if you still haveing the same problem
refer to an earlier post about similar problems. Does it power up and then shut itself off. this is possibly due to two defective capacitors. 27 cents on line $1.50 at radio shack. They will be puffy on top.
I am a complete novice to soldering a capacitor onto a board. but since I was junking the monitor otherwise I gave it a try. It's still working after sitting idle a year. Handy advice on soldering online.
use copper wire to **** up the old solder and try not to fry the capacitors or the board. If I did it anyone can.
