Viewsonic vx2235wm wont turn on or light up. its dead

SOURCE: ViewSonic VX2235wm monitor looses power ...

The first thing to try is to make sure the power cable is tight. I know it sounds too easy but with the movement causing the power outage it sounds that or a broken power cable. Check the cable to make sure it is tight and it that isn't it, change the power cable. If neither of these work you probable have a loose connection between the cable plug and the power supply on the unit which will require soldering and professional help to fix.
Good Luck,

The problem is most likely the monitor itself. Hook up an old monitor (usually someone has an old monitor laying around) if the computer works with another monitor you'll know for sure.
Look at your monitor using a flash light at an angle, if you can see a picture in the background you have a bad inverter.

Hello,

The Viewsonic VX2235WM has a known issue with the power supply going out. The flashing power light or not turning on is the classic symptoms of this issue. Check out our web site at: www.ccl-la.com. We have a step by step repair guide posted that will guide to doing the repair yourself. It involves changing a few capacitors on the power supply. If you can solder then you should be able to do the repair yourself. If you don't want to do the repair we do offer a repair service for $35 plus return shipping. If you have any additional questions just let us know at: [email protected]

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

It's a backlight or backlight inverter issue. (The backlight itself usually fades or makes the on-screen image change to pink/red.) For an out-of-warranty monitor, open up the back of the monitor and remove the shielding. Look for any scorch marks or bulging or damaged capacitors. (Sometimes other parts will fail on this part but these can be spotted easily. Capacitors look like cylinders on a tripod.)

If you borrow (or have a) high-end multimeter (able to measure high frequencies - 50 kHz) or an oscilloscope, hold the multimeter probes a fraction of an inch apart about an inch above the board and power up the monitor. If you see a 1 or an actual value, you have a good inverter. If you see a reading near 0, the board is bad or the multimeter can't resolve the frequency.

In either case, you can buy a replacement inverter for $50-150 and just do a simple swap. Disconnect all of the wires (connections are similar to molex and ribbon cables in a computer) and remove board (a few screws usually). Connect the cables to the new inverter. (If you google backlight inverter replacement, you'll find videos and text descriptions.) Note the part number on the board, including the Rev number, and order the exact one (shopjimmy.com or lcdparts.net are good starting points). Universal inverters do exist but can result in reversed controls (up to lower the brightness). Replacing individual parts on the board is cheaper but more prone to not tracking down all of the bad parts.

If the inverter is good, then it's probably backlights themselves (several in most TVs). These are sandwiched on the perimeter of the monitor (usually under some tape that holds the lamp, reflector and other parts together. You need to order by length and width and get ones for your monitor size. Remove the tape, and separate the reflector (make a note of how things are put together) then you have to Dremel (or use another rotary tool) to remove the plastic to get the backlight out. (They are often molded into the frame.) Then put in the new backlight and reassemble everything. (http://www.lcdparts.net/howto/default.aspx) but for an overview: http://www.inventgeek.com/Projects/BacklightFix/overview.aspx

With a good spare backlight, you can test an inverter for condition (plug together and turn on the tv while the box is open). Similarly a good inverter can test the backlight. With a bad backlight, you'll usually see a very dim image if you look at the monitor from an inch from the screen. Block the room light from overwhelming this image (sometimes a carefully positioned flashlight will help you see something). If the inverter or video board is bad, you will see nothing

I hope this helps.
