My Westinghouse LCM-22W2 has a blinking LED now. Before it would turn on and show the info for two seconds then go black. I replaced the caps and now it just shows a blinking LED... stays on for five seconds then goes off for two seconds and repeats. Please give me some idea of what to do next... thanks in advance for your assistance.

First place to check will be the caps and voltages in the power supply section and go on from there to the backlights inverter circuits. I hope it is not lamp assemblies.

There is no tuner in the monitor, it only works as a TV with a tuner added. The remote would work with the tuner, not the monitor !

Can't find correct setting for westinghouse lcm22w2 monitor


I don't know if this actually will fix your problem, but all LCM 22w2's are plagued with the 'white screen of death' and eventual power shutoff, including garbage characters and faulty menu, video output, etc. Here's how I fixed it.

The Westinghouse LCM 22w2 has bad capacitors on the yellow power supplyboard. This is a common problem plaguing motherboards and LCDflatpanels that use capacitors from Taiwan. If you know how to solder,or know somebody that can, it's actually a pretty easy fix. Take outthe yellow circuit board on the inside, write down the specificationsfor each of the capacitors (the cylindrical things) go to theelectronics supply store and get the replacement capacitors. You can goover the voltage specification (not under), but keep the capacitancevalue matching. Replace one at a time. Go to www.badcaps.net foradvice, tutorials and training on doing this. *You really shouldreplace all the capacitors*, but the very large one next to the powerplug I did leave on the board because I couldn't find a match. To mydelight, the white screen of death went away and it was working as new!

I saved a ton of money fixing this, it's definitely worth learning how to solder to do this.

My Westinghouse LCM 22w2 (1 year old) has developed a green line running top to bottom of the screen. I cannot get rid of it. I've tried turning the monitor off, changing inputs, reseting - but it's...


Unfortunately that is a failure in the display electronics and is repairable only by replacing the display panel. I don't know what the warranty period is for this model, but check your purchase date and the warranty information. If the thing is just recently out of warranty maybe the manufacturer will work with you on a solution. Or you can contact them anyway and ask. Sometimes if you complain loud enough it works wonders.

Westinghouse LCM22W2 shows a display then turns off after half a second


I have the same problem and have traced it down to a potential power supply issue.  I bought mine at Best Buy in '06 and was told today that they will test the power supply for free.  It may range from $50.00 to $100.00 depending on where you can get it.  This does not include labor for those not qualified to work with electronics.  Hope this helps you.
