replace lcd monitor ccfl backlight?
I have a lcd with a bad ccfl backlight. It has dark spot at both end of
the tube. When the lcd is on, the bad one flickers and has less light. Question: I found a good backlight from a broken panel(different panel model #) with the same length, diameter. However, I dont' know the lamp's starting voltage, working voltage and watts. If i want to swap the lamp, do i have to know these parameters? |

replace lcd monitor ccfl backlight?
Most of the ccfl lamps will work anywhere between 900 and 1200 volts
AC. They are fairly interchangeable, if about the same size. I have even used a lamp from a flatbed scanner in a LCD monitor. The lamp was an inch shorter and about twice as thick, but it still worked until I could find a better one. I would try it. Hope this helps.... John wrote: I have a lcd with a bad ccfl backlight.
