Kogi lcd monitor L5BX

The monitor powers on. It shows bright for 2 seconds. It displays "no connection" in bright and dim states. Checked all connections, they are OK.

How do I determine what boards and screen to order from vendor?

THANK YOU

    Rand chkdsk /r from recovery console, but no change. Found a driver:http://members.driverguide.com/driver/de...
    Can't figure how to install driver if I can't see the screen. Found "Gvision" in tiny print on the product label. Gvision seems to say use the generic video driver that comes with the system. So after going in loops for hours I'm giving up for now.

Acer Aspire 5735 LCD changes bight-dim-bright, etc.


You could have a faulty inverter, To determine if you have a LCD screen, inverter or video card problem, read this and follow these instructions.
Defective CCFL backlight, it may have the following symptom: Screen flashs on red/pink and off. Picture stays on in red and slowly be come normal. Picture flickering with dim display or appear black. Picture flickering on and off. All these symptoms indicate that the LCD backlight lamp (CCFL Lamp) has reached the end of the life and all you need to do is replacing the CCFL lamp.
Connect an external monitor to your laptop and power the monitor up first then the laptop, if you see the normal Windows images then the video card and laptop is OK and the problem is definitely the backlight. Dim image and/or dark display on the laptop's LCD screen indicates a faulty LCD backlight and it could be the inverter that supplies high voltage to the CCFL lamp or it is the CCLF lamp is nearly burnt out or burnt out, most likely this is the case.
The inverter can be replaced easily but the CCLF lamp is more time consuming and requires soldering skills.

My Kogi 17 inch monitor illuminates for 2 seconds and then the light goes out. The monitor is still on but hard to see. Each time you power cycle the monitor, the display appears normal for exactly 2...


Hi and welcome to FixYa,

Initially, lets try determining which is at fault.
  • power supply (unlikely) - the unit powers up, even after the display going off, the monitor is till on;
  • LCD screen (possibly) - will have to be determined later;
  • CCF Lamps (backlights) and/or inverter (most likely) - a check; power on the unit, run through the routine, change channels etc. with a flashlight shine obliquely against the screen. If with the use of the flashlight a darker semblance of the desktop could be seen, then you have just confirmed that it is either the CCFL or the inverter and definitely not the LCD screen.
Good luck and Thank you for using FixYa. Happy Holidays.

HP dv1000 monitor just stopped working.


Description During the startup or boot process of the notebook, the display is very dim and barely readable. It remains dim when it reaches the Windows desktop. Restart the notebook with AC power Perform the following steps to determine if the dim display is due to a hardware failure:
  1. Connect the AC adapter to the notebook and a working electrical outlet.
  2. Power down the notebook PC by pressing and holding the Power button for 5 seconds.
  3. Press the Power button again to start the computer.
If the display is still dim after restarting with the AC adapter connected try changing the LCD brightness. Change the LCD brightness From the Windows desktop, hold the Fn key and press the F7 and F8 keys to increase or decrease the brightness of the display. If using the function keys does not resolve the problem, determine whether the Lid Actuator switch is stuck. NOTE: The key number may vary depending on the notebook PC. The image on the key should resemble the following images: Figure 1: Brightness Level Down c00776225.jpg Figure 2: Brightness Level Up c00776226.jpg NOTE: During battery power operation, the notebook display will dim to reserve battery power. Adjust brightness control using the control panel Some notebook PCs have the ability to adjust the brightness through video drivers. If the notebook PC has video drivers with this capability, perform the following steps:
  1. Click Start , Control Panel and then double click Display .
  2. Select the Settings tab and click Advanced .
  3. If the feature is available, a tab with the video card name will be present. If it is, select that tab.
  4. Adjust the desired brightness.
Finding the Lid Actuator switch The Lid Actuator switch is a small button or switch located above the keyboard and LEDs on the right or left side of the notebook. It may also be located near the display hinges. Pressing this switch when the computer is on may turn the notebook display off or cause the notebook to enter a different power state. Press the switch 2-3 times while observing the display. If the display is no longer dim the switch may need to be repaired. Contact HP service and support for further assistance. Contact HP service and support If the display remains dim after the troubleshooting in this document it may be possible that the backlight is damaged. Please Contact HP service and support to schedule a repair

Monitor will not power up


Hi tafkab, Sounds like it's probably the backlight inverter board. Try the test I have at the bottom to see. It's a very common problem. LCD's use four small Cold Compact Fluorescent bulbs to back light the display. (thats what gives the LCD it's brightness allowing you to see it) The inverter board runs these lights and when they go bad they will typically show symptoms like you have or the monitor power light comes on and you have either no display or a very dim display. If you ever have one that has no display but the power light is on you can check by shining a flashlight directly into the LCD from the front (right into the screen) if you can see an image then it's either the inverter board (most likely) or the CCFL bulbs have gone bad. The inverter board and CCFL's are replaceable. Good Luck, Dude
