    Same problem with mine. It started flickering when I'd fire up the computer a couple of years ago. Most of the time. the machine is on. Lately, when restarting, the monitor would not come on, even thogh the light is green. If I hit the power button it blinks on for a second (kind of dark when it does) then goes right back off. Will attempt the capacitor soldering mentioned here and get back with you on whether it works or not.

I have a Westinghouse LCM-20v5 that would have problems powering on, and then it would power on for about 1/8 sec and lose the picture. It died 1 year and a few months after purchase. That sucks. LCD screen problems are often caused by the internal power supply. A new power supply unit can be ordered, but they run about $100 - hardly worth the gamble if you don't know for sure.. Since mine was as good as garbage, I figured that there was no harm in taking a look-see at the innards. When I did, I found some power-supply capacitors that were obviously in distress.

The 19v5 is probably almost the same, so maybe this will help.....

If you know how to solder, or know someone who does, you may be able to fix the whole thing in an hour or two.

I replaced 5 capacitors in mine ($7.86 for all from Radio Shack), and I am now using it to write this.

1 - Put the screen face down on a nice soft relatively flat surface (carpet or bed will work fine) and crack off the back plastic piece (I literally cracked it, as 2 of 4 plastic "claws" broke). It turns out that there is a trick. I think that pushing in really hard from the sides AND pulling at the same time might get it off cleanly.

2 - Remove the (now obvious, after removing the plastic cover) 4 screws that hold the stand onto the unit

3 - Remove the 3 screws that hold the main plastic back of the screen on. After that, it's a matter of careful prying. Remove plastic cover.

4 - The power supply cover is now in view. It is held on by a crafty arrangement of screws and those hex screws that the monitor cables plug into, plus two regular screws for the power supply cable.

5 - four small double wires go into the power supply cover from two adjacent sides. Pull these out - there is no trick, just pull. Mark these with a sharpie to make sure that upon reinstallation, they go into the right sockets and right side up.

5a - You can now slide the cover up and off and remove the power supply board (the one the power cable goes into). 4 screws hold that on, and you have to sort of pull it off sideways and jiggle, as it mates with another board. Be careful - there is one relatively big cap on the power supply board, and you don't want to shock yourself. Short it with something metal to discharge, or at least don't work on your screen RIGHT after unplugging it from wall power. Mine had been off for a couple of weeks, and the big cap registered nothing when I checked it with my voltmeter.

6 - for me, on the 20v5, I looked for capacitors that had "swelled" tops. I saw 5 that were swelled upwards. Caps are supposed to be flat on top - swelling means that they are messed up or close to death. The deceased/suspect capacitors were 2 1000uF and 3 220uF radial-type, all 25V max.

7 - ripshack has these in stock, but they have 35V max ones. If anything, replacing the 25V ones with 35V ones is a good idea, as the old ones couldn't handle the job. Unfortunately, 35V ones are bigger in size. It required a bit of shoehorning, but the larger ones fit. I had to solder one about 1/4" off the board and bend it over a bit to make room for one of the other ones that I was replacing.

8 - solder very carefully, it's tight in there. Work the old cap out side to side, melting the solder joint, pulling, going to the other side, etc. Put the new one in (with the polarity CORRECT) - white stripe on side of cap is "-", other side is "+". You should see the "+" sign written on the circuit board, too, but just pay attention ahead of time - it's easier.

9 - Make sure that all caps are close enough to the circuit board that they do not go above (heightwise) the larger caps that HAVEN'T failed. Otherwise, you won't be able to get the power supply cover back on.

10 - slap everything back together and power up! If it doesn't work, then you blew $8. Big deal.

Does the LED light turn blue? Try plugging it in to a different outlet.

My Westinghouse LCM 19v5 will not powerup


Look for bad caps with bulging tops, similar to the 19" version as shown here:

Make sure to use correct type caps for switching power supply.

My monitor Westinghouse Mod# LCM-19v5


Hello,

The most common thing that causes no power or a blinking power light and no picture is a failure of the power supply board. The board can be repaired and the monitor will be as good as new. To repair the board you just need to replace a few parts called capacitors. Here is a link to repair information on the Westinghouse LCM-19V5

I hope this helps, if so please rate my solution.

I picked up a used westinghouse monitor, LCM-19v5, and it works fine as a plug and play. I was wondering if there might be a driver for it to download that might make it even more crisp and sharp.


This monitor only uses plug and play drivers and unfortunately there does not appear to be much support for them on Westinhouse's support site.

Power light flickers green, no image


Check the capacitors in the power supply, see pictures here for a guide so you know what to look for.

I believe the 19v5 uses the same chassis as the 20v5.

Does not power up freind thinks it's a blown capacitor


Yes, it can be that and other components.
Most common failure 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 WESTINGHOUSE (LCM-20V5 may be thesame chssis as yours) and monitors to get some ideas what goes wrong: http://s807.photobucket.com/home/budm/allalbums

Screen goes black after fraction of a second


More likely to be bad capacitors in the power supply, see LCM-20V5 (almost the same chassis as used in LCM-19V5) example: http://s807.photobucket.com/home/budm/allalbums

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
