I did a google and couldn't find anything even though the word Xenon is used in several products.

I think the reason why they don't have one available could be due to the mercury switches in them or other hazardous material contained in them as well as accessibility issues.

How to replace a hp2159m backlight


It is not recommended to replace the backlight unless you have a clean room. Doing so may introduce dust into the LCD panel module. The LCD panel module is held together by metal brackets with latches. You'll need to remove the two metal brackets that hold the sandwiched LCD panel modules together. The you will have access to the actual backlight. Older panel technology made it easy to slide out the backlight for replacement. Nowadays, they lock up the CCFL into the LCD panel module making it not really possible to do backlight replacements if you don't want to introduce dust into the system.

1100 ferrari acer power but no screen?


Assuming no BIOS is displayed
  • Memory could be bad
  • Motherboard could be bad
  • Backlight could be bad
  • Inverter could be bad
  • Screen could be bad


Pull the memory modules out and boot the computer if it makes it to BIOS and then beeps at you one or more of the memory modules are bad, replace one at a time if you have more and test until it breaks again then you know which to replace.


To Test the inverter and backlight hook up an external monitor and boot the computer. If it displays correctly on the monitor then you've narrowed it down to a bad screen, inverter or backlight. Backlights don't usually go out.


Remove the monitor and boot the computer. Shine a flashlight on the screen and look for a very faint image of what should be displayed. If you see one I'd start by replacing the inverter. If you don't see one the screen is bad.


If none of this worked then replace the motherboard.

It will be the inverter module or the the back light that is the problem, but until you take it apart and examine the parts and do some testing that will be the key in finding the culprit.

When I turn on my computer the monitor turns on for about 3-5 seconds and then goes black. The blue light stays on and does not blink. If I turn the monitor off then back on it will again show the screen...


Had same problem, Monitor first turn on, backlight off after couple of minutes, off/on backlight off after few seconds.
Solution cut J503.
Found voltage OVPT (IC501,7) quite low (1.6V) this is the reference value for VSEN the over voltage value. By cutting J503, OVPT becomes 4.5 volt but is not depending anymore on the current through the lamps. Instead of the link J503 I solder 2x 1N4148 diodes which makes the OVPT not go below 2,8 volt. (diodes in series, cathode points to nearest board edge)

I turned on my toshiba laptop and the comp. comes on but there is total black on the screen


Turn you laptop off. Connect an external monitor to your laptop. Turn the laptop on and see if you get any video signal on the external monitor (you have to use the right button combination e.g. Fn + one of the Function keys). If you get a signal on the external monitor the problem comes from the screen/backlight/inverter/cable of the laptop. If there is no signal, check the memory (if you have 2 memory modules use only one at a time, the other one could be defective or check your memory with another laptop or use some known good memory etc.). If the memory is ok then most probably the motherboard is defective (at least the integrated video card). Expensive to fix or to replace it. Have it checked by a professional.
Do you have any warranty on your laptop? See your dealer or the manufacturer’s representative first.

HP Pavilion ze2000 Monitor is dim


Yes, this is what happens when the backlight goes out.
This will give you an idea of what is involved in replacing the backlight. You can find a replacement backlight here, or on ebay, just take your current backlight(s) out, measure it or them, and buy replacements of the same measurements. It doesn't have to be for the same model laptop as long as the CCFLs (cold cathode florescent lamp) are the same size.
