    Brand new out of box. Bought it from walmart's sale starting 3AUG. Plugged everything in and absolutely nothing happens when I try to turn it on; not even the monitor config menu works. No flickers, whites, noises, LEDs... nothing.

I fixed it! It's the power supply board. You might have the "white screen of death" problem, and if not you may just need a new board. The board is yellow, it has markings on it that you can look up on a search engine for resellers, and I saw several going for $20-35 after searching google.

The Westinghouse LCM 22w2 has bad capacitors on the yellow power supply board. This is a common problem plaguing motherboards and LCD flatpanels that use capacitors from Taiwan. If you know how to solder, or know somebody that can, it's actually a pretty easy fix. Take out the yellow circuit board on the inside, write down the specifications for each of the capacitors (the cylindrical things) go to the electronics supply store and get the replacement capacitors. You can go over the voltage specification (not under), but keep the capacitance value matching. Replace one at a time. Go to www.badcaps.net for advice, tutorials and training on doing this. *You really should replace all the capacitors*, but the very large one next to the power plug I did leave on the board because I couldn't find a match. To my delight, 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.

Thanks MattKC for the solution! I just fixed mine too. I was able to find some links to some replacement power boards across the 'net, for about $45 including shipping...

But then I got bold (and since the monitor was given to me b/c it didn't work) and decided to try the fix myself. Went to Mouser Electronics (www.mouser.com) and spent $10.50 including shipping (I don't know of any good local component suppliers around me, and RadioShack just doesn't have jack anymore), and just replaced them myself. There was one that I didn't replace (22uF, 50V cap) because it was real close to a lot of surface mount components, and my soldering skills are not all that great, so I didn't want to chance it... Replaced all the rest though, and ta da, now it powers up just fine!

This solution worked for me. Thanks!

M93p suddenly the screen goes black screen


Here's some tricks I would try...
1. Verify the monitor's power cord is plugged firmly into the wall outlet and the back of the monitor.
2. Verify the monitor cable is firmly connected to the computer and the monitor.
3. Verify that you have turned the monitor power switch on.
4. If the power light on the monitor is not on, test the wall outlet (plug in a light or something you know works).
5. If the power light on the monitor is not on, try a different power cord.
6. If the power light is on and yellow or orange or flashing, but nothing displays, or the display is incorrect, borrow a monitor from a friend. If that works, your monitor probably needs replaced.
7. Also, you could try your display on a friend's computer. If it doesn't work, your monitor probably needs replaced. If it works properly on your friends computer, the problem may be with your computers video output port, motherboard video chip (or video card, if you have one), or drivers.

Good luck

Gateway dx 4320 wont turn on


It could be a few things:

a faulty power switch - you say that you've changed the PSU, but did that include the switch?

it could also be a Faulty Motherboard or CPU. If either of them are fried, you won't see anything come on either.

I'd suggest checking the switch first because that's the cheapest and easiest to replace

TV won't turn on power light flashes 10 times


Switch off the TV from remote, then switch off the on/off button on the TV, remove the plug pin from the power outlet. Cool off for 48 hours and then retry. If nothing works, better refer it to a qualified service technician.

Acer Aspire 5536 only gives black screen when i connect power supply


  • Nothing is more annoying than a monitor that refuses to turn on. Make sure your Acer monitor is plugged in to a functioning outlet. If it's plugged into a power strip, try replacing it with a new one or moving the plug to a different outlet. Ensure that both ends of the power cable are plugged in firmly and securely, and that the connection to the monitor is not loose.
Cable Issues
  • Your Acer LCD monitor will usually accept DVI and VGA inputs. If you have an older computer, a VGA cable should work fine. If it doesn't have a VGA port, you'll need to obtain an inexpensive DVI to VGA adapter at your local computer store. A DVI cable, however, is compatible with most modern computers and offers superior picture quality over VGA. Make sure you're using the cable that's compatible with your system, and that you have the proper conversion adapter, if necessary.

My panasonic TH42PX60U won't power up. No red light flashing. Completely dead. I tried unpluging and using different power outlets. Still nothing. Any help?


1. Check all cable and input connections are secure & all are tightly connected.
2.Check power cords and also power outlet , if possible try to unplug and reconnect . A replacement of power cable or use another power outlet is another good option.
3. If you are sure that power is reaching your TV(check it out with a test lamp that both neutral & ground or earthing is functioning, i.e. the test lamp glows) then probably the power board needs replacement.

My tv won t turn on i just purchased it today i plugged it in and it won t turn on


Check the electrical outlet which the tv is plugged into. Make sure nothing is loose at the outlet as well as on the back of the tv where the power cable plugs in. Another thing to try is plug a different device into that same electrical outlet and see if it turns on. If it doesn't turn on, it could be a faulty electrical outlet. If you've tried both the remote & the power button on the tv, a shot in the dark would be to change the batteries in the remote.
You could always try calling their tech support at 1-800-256-2487. A last resort would be to return the tv from where you purchased it.

My D-Link AirPlus Xtreme DI-624 Wireless Router all of a sudden doesn't power up when I plug it in. I've tried other wall outlet on the outside chance that the outlet I tried doesn't work, but to no avail....


Base from the description of your problem that the router wont even power ON this can be cause by several reason , like the power outlet is bad and since you already tried a different power so that is not the problem, this can be a problem with the power cable that you have so if possible for you to try a different power cable to test the router that will be good and if still wont power ON using a different power cable the router is already dead and needs replacement.

BLACK SCREEN NO BOOT ON HARD DRIVE OR O.S.


US has 110volt power outlet while other countries like Philippines have different power outlet outlet voltage of 220v. You cant use the same power adaptor that you use in the US but if you use a power regulator like a UPS device it wont have a problem
