Kogi Recent Questions, Troubleshooting Help & Support

I read somewhere on another thread that you are supposed to power off the monitor and hold the down arrow while turning the monitor back on and it should reset the keylock. good luck hope this helps you

Change your cord from your monitor to your P.C

I googled "Kogi L7CH power supply" and found 25 results from $11.15

you will need a signal cable

Try starting it in safe mode, F8 during the boot process, this loads a windows shell, once active, run a system restore.

(Programmes - Accessories - System tools - System restore)

Choose a date prior to your problems.

Check the default power settings. Start -> Control Panel -> System & Maintenance -> Power Options. The default will turn off the monitor from five to fifteen minutes. Moving the mouse should turn it back on. Make sure your video out is activated. On most laptops the key looks like lOl. And its usually in the F4-F8 range

If you are going to DIY and have proper tools and know safety precaution then please read on:
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, blown fuses; poor solder joints, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed monitors to get some ideas what to look for: http://s807.photobucket.com/home/budm/allalbums
Post back what you see inside so we can guide you further and it will help out other people in the future also.

Do you get a No Signal on the monitor?

IF so, the problem is in your computer, or you have a bad monitor cable. (Cable from monitor to computer)

Try the monitor on a known working computer, and use that working computer's monitor cable.

Monitor works?

Okay now use the monitor cable from the Dell Inspiron 537.
Monitor works?

Problem is in the computer.

Monitor doesn't work?
Problem is the monitor cable. They do go bad.

Problem is the computer? Check to see how dirty the computer is inside. Unplug the computer from power, open the computer case.

DO NOT reach inside, and touch any components, even to clean, until you have touched the metal frame of the computer case. You are just looking for now.

[ Your body carries Static electricity. Static will fry out the hardware components inside a computer.

Static will do it in a flash, and you won't see it, or feel it!
Computer unplugged from power, you're safe. Touch the metal frame of the open computer case, your computer is safe ]

If the inside of the computer is dirty, so is the power supply. The case fan/s draw air into the computer, and push the air through the computer case.

The power supply fan draws air through the computer, and pushes the air out of the back of the
computer.
Anything that goes through the computer, also goes through the power supply.

Dust, Dirt,. Hair, Lint, Carpet Deodorizer, you name it, can be drawn in. (Sometimes, spiders make webs inside!)

Inside the Dell Inspiron 537 Desktop PC, is a processor with a Heatsink on it, and a Fan on top of the heatsink.

The Heatsink is a square looking device, that has fins on the top.
The bottom is flat, and is attached to the top of the Processor's case.
The heatsink absorbs the heat of the processor, by being in close relation to it, and the fins radiate the heat up, and out.

(What an average Heatsink, and Fan combo look like,

http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=2943299&CatId=493

There is also Thermal Paste, in-between the top of the Processor case, and bottom of the Heatsink)

The fan attached to the top of the Heatsink b-lows the heat away.
If the fins become clogged, and the blades of the fan, the processor heats up.

When the processor becomes too hot, it turns off.
This is a Fail Safe feature that is built-in. BIOS turns the Processor off.

During this, the Processor has been calling for more power, due to the heat.
The power supply tries to keep up.

The power supply has Heatsinks inside it, also. Plus a fan, to draw air across the components inside the power supply.
This is the power supply's cooling system.

Once the fins of the heatsinks become clogged, and the fan blades, the cooling efficiency drops tremendously.

The power supply heats up.
Again, Heat = Wasted Energy.

The power supply tries to put more, and more power out, until eventually the components inside the power supply fail.

Power supply failure is a main cause of computer failure.

If the LCD monitor has a faint Windows image, then the LCD monitor has a back-light problem and it could have a faulty inverter board or a faulty CCFL lamp.
Parts and service are available from LCD Parts, their WEB site is :-
www.lcdparts.net

There are little tube lights in the monitor that are like the big florescents in buildings. They are powered by a voltage inverter. What you are talking about sounds like the inverter. If it was the lights you would have gotten bad color before it went out.

Try booting in safe mode per instructions here: http://www.fixya.com/support/r4873371-fixing_out_range_format_not_supported

You need to find out if the proper video card driver is installed when you use recovery disk. Compaq usually supply separate disk for the drivers.
Try using resolution of 1024x 768 @60 Hz first and go up from there.

Is your remote working? If so use the key pad and open up the menu- look for advanced settings, press unlock (parental controls) also use the default setting to auto reset the channels....

if you have the type of connections on your laptop, find the correct port and connect the monitor to it using the same cable you use for your desktop.
after the monitor is connected to the laptop and turned on, go ahead and press the key combination (Fn+CRT/LCD) you have to press both at the same time or hold Fn and then press CRT/LCD, you may have to do that two or three times in order for you to get the correct set up and you would see the choice on your laptop. Select the one that you prefer.
if it works for you don't forget to rate me
thx

Yes, this is a 1024x768 native, analog-VGA monitor.

If this helps, please be sure to hit the "thumbs up" for me!
