Without parenthesis, I assume you mean 12 a b^2 and 22 a^2 b.
To do a LCM, just find all the prime factors, select out enough to cover both entries, and multiply together. 12 is 3 * 2 * 2. 22 is 11 * 2. You need two 2's. So you need 2 * 2 * 3 * 11 = 132. And you need 2 a's and 2 b's. Answer 132 a^2 b^2.

### 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.

### Can't remove cover of Westinghouse LCM-22w2 monitor

Hey Ed,

I hope I can help, It doesn't open from the back, it opens from the front.... carefully! There are four support screws, which hold the LCD screen to the desk stand,after removing all the support screws (4) on the back under the support stand cover.(which pull up to remove) (Remember! the whole case and face frame is plastic, so take your time). Work to separate the black face frame around the LCD from the silver case. Its held together by small plastic clips on the face frame to the wall on the LCD case. Start at one of the corners and slowly pry the face frame and silver case apart. (separate it inch by inch, work your way around the case carefully. If one corner doesn't give, go to another side.
Putting back together works reverse, the face frame and the case snap back together, Carefully! And replace screws (4).

Russell

P.S. I have three LCD models from Westinghouse, LCM-22w2, L2210NW and the L1916HW. They all open the same way.

### 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.
