Question about IBM ThinkVision L170 17" LCD Monitor

IBM LCD Monitor Model # 6734-ABO

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.

Adam,

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!

Sounds to me your high voltage powersupply is out. To repair open monitor and remove high voltage powersupply. Inspect the caps on the board. Look for the ends of the caps to be mushroomed out. Replace these caps, usally 470 uf caps. Replace with 25volt caps. Might also be some 100uf caps as well. This is a common problem with all LCD monitors.

I have an image with the flashlight, but no backlighting on my IBM 6734 lcd monitor


The inverter module is bad or the back light behind the LCD screen has stopped working, I would suggest an estimate if you decide to have it repaired.

LCD flat panel monitor blinks logo over and over


Sounds like the LCD monitor is not getting a proper input signal. Check your cables between the computer and monitor. Replace them if need. Also check the pins and make sure that none are bent or disfigured.

Try a replacment monitor from a family member or friend. If their monitor works ok.....then your due for a replacment. The are very little user servicable parts inside.

Proview 900 series black flat panel monitor


Same problem, and solution 1 given here fixed my Proview 900W. A few of the 470uF caps on the power board were oozing dielectric probably due to overheating. Hopefully the replacements will hang in there for a couple more years...
