Question about IBM ThinkVision L170 17" LCD Monitor
Hi! How are you? This monitor was working perfectly when suddenly, No picture... Like the other posts pointed out, You can shine a flashlight at the screen and see the image, so something is wrong with the backlighting circuit. Now I have to assume that "caps" is an abreiviation for capacitors... There appears to be one board for graphics rendering and one dedicated to backlighting. I am an auto mechanic, not an elecs tech, but I would think if the problem were the back light bulbs, then all of them would not fail at once, correct? I have looked for a fuse in this unit and found nothing that resembles a conventional fuse anywhere. Is there a schematic available anywhere for this unit? What would the fuse look like? Which capacitors are responsible for the backlighting circuit? Thank you very much. Would just buy a new unit but am totally broke.
How would u test the capacitors on what setting?

Well, to look for a bad capacitors you need to tested with a ESR meter. But if you are lucky sometime you can spotted just by look at the top of a caps for stress mark (like it going to burst out). The caps look like a tiny battery, other look like a blue button with 2 pins. Sometime it not the caps problems...it's beyond repaired. Anyways, good lucks!
