Having problems with your Xerox XA3-17B 17" LCD Monitor ?

Screen is dark... you can see and interact with screen, but too dark too make out clearly, brightness and contrast set to highest level on osd! is there a backlight that can be repaired?


Answers :

This can mean either a bad backlight or inverter. The backlight is dificult to get to on most lcd screens, it is in the screen itself and trying to take apart the lcd's layers usually ends up a broken lcd. Luckily the problem is usually the inverter, which is cheaper and easier to replace.

Normally this is caused by the power inverter for the lcd.\015\012It is a small circuit board right below the lcd, that powers the\015\012backlight. If you take off the front bezel of the laptop you should be\015\012able to see it, it will have a 2 wire power cord coming out the one\015\012end, and another plug in on the other end with several wires.

9 times out of 10 the problem is just the inverter going out, check ebay for a replacment but make sure you get an identical model as the one you have, as they are very specific to each laptop. The inverter will have the part number written on it.
