Probably a bad power board if no lights come on. If lights come on then it's either a bad inverter or screen backlight. None are user serviceable, unless you've taken screens apart before.

Monitor flashes logo and then turns black.with red lights on


Here's some tricks I would try. Something here, might help...
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 monitor 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.

Hook up to home pc


Today's laptops and desktop computers are more user-friendly. As more people start use computers, operating systems, software and hardware accessories are coming with better instruction manuals and streamlined interfaces. Here are a few basic steps to hook up your computer no matter which brand you bought.

Connect the power cable to the back of the computer tower. The male end of this plug is often on the computer, but it is recessed into the casing. Once this power plug is connected, you don't want to plug it into an outlet until the entire computer is set up. Attach the monitor cables to the back of the monitor and then to the back of the computer tower. This cable will probably be the VGA type, which has a wide set of prongs in the middle and two screws on the outside. Be sure to twist the screws in to ensure the cable has a solid connection. Secure the monitor's power cable to the back of the monitor and then plug it into an outlet or power strip. Attach the mouse to the USB port on the back of your keyboard. The keyboard then plugs into another USB port on the back of the computer tower. Turn on the computer and the monitor.

If the computer powers up but the monitor doesn't display anything, make sure the VGA monitor cable is secured. If the status light on your monitor doesn't turn on, check the power cable connection. Check that the mouse and keyboard work once the computer turns on. Now you can hook up other devices, such as a printer or a web cam. A printer often can connect to a USB port and also may have its own power cable; a web cam usually just plugs into a USB or firewire port.

When I came home today the blue monitor light was on, but there was no picture. When I moved the mouse to get the monitor up, the light went out. I've tried unplugging it and plugging it into...


Here is a link to a repair guide for the LG L196WTQ. It sounds like you have a power supply failure and the guide shows how to open the unit, check the power board and then what to replace if you do find bad capacitors.

http://www.ccl-la.com/blog/index.php/lg-l196wtq-bf-lcd-monitor-repair/

Problems like wavy or flickering picture, flashing power light, slow to display the picture or no power at all are all symptoms of a failed or failing power supply board.

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

My monater will stay on for about 5 minutes then it goes to a black screeni called and already tried to reset but did not work


Try these steps for resetting.
  1. Unplug power cord from wall and monitor, if it unplugs from monitor.
  2. Unplug the video cord from monitor and computer both. 12d39cb.jpg
  3. Hold all buttons on the monitor down for about 10 to 15 seconds while everything is unplugged.
  4. Plug everything back in and see if that fixes it.
I know it sounds weird but holding the buttons down releases any residual juice ( power ) in the monitor. If this doesn't solve the problem you may have a bad monitor cable. I would see if replacing it helps.

Hope this was helpful.
Good Luck

It wont power up bro


It is possible that your monitor is on a GFI switch. These switches turn off if they detect a problem that could incur a shock, or if they are getting worn. Check if there is a power outlet in the same room with a red and black switch. If so, push the reset switch, typically the red one.

Your monitor may also be on a switch activated outlet. Is it plugged into the top outlet? See if a wall switch nearby controls the outlet. then try turning on your monitor.

Is the surge protector your monitor is plugged into turned on?

Check the cord on the back of your monitor. It is possible it may be loose. Plug it in all the way.

Some Viewsonic monitors have a power pack that is not inside the monitor case. Check the wiring between it and the wall and between the pack and the monitor for frays.

The monitor had been turned off and will not turn back on, why?


LG is well known for their power supply problems.
1st things to check of course -
1) A/C power outlet it's plugged into fine or operating fine?
2) Power connection to the monitor all the way plugged into the monitor?
May be a time to find a good trust worthy TV repair shop.

There is no power to my TV. I have checked fuses and sockets and they are all working


plug something else into that outlet to see if there is power there. if there is no power you should replace the fuse anyway as sometimes the fuse looks ok when it is not.

if there is power at the outlet plug the tv back in and try it again. if it won't start up the problem is likely in the start button.
