The entire Thinkvision series of monitors have been plagued by capacitors on the power supply board failing.
This sounds worse then it is. For the most part they only fail well after their warranty period, so it's not a design flaw, just old age.

The repair should not cost alot and would be worth a trip to your local computer/TV repair man.

Hope that helps =)

IBM monitor out of range


Change your resolution to something lower. Sounds like your video card is overdriving your monitor. Reset your resolution to 800 x 600. If that works ok, you can push it a little higher.

I have IBM Thinkvision L150, 15". when computer is started green light is lighting but LCD couldn't display and it looks blank or black. Ok.


If you are going to DIY and have proper tools and know safety precaution then please read on:
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply (they should be replaced in a set), blown fuses; poor solder joints, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed monitors to get some ideas what to look for: http://s807.photobucket.com/home/budm/allalbums
Post back what you see inside so we can guide you further and it will help out other people in the future also.
Not sure about spending any money on 15" monitor.

17 lcd l170 black screen power on but no display


When powered-on, and *NOT* connected to a computer, most ThinkVision LCD monitors will flash, for a few seconds, the IBM ThinkVision "logo", before going into "power-saving" mode. If you don't see that, then it's time to spend about $120, and buy a new 19" (not 17") LCD monitor.

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.

Monitor wont turn on, green power light on


Hi you can inspect that what's wrong with your monitors. After you turned it on and the screen went black, you have to check that if you can see the image on the screen or not by shining a flashlight into the screen, not directly but find the best angle to the screen and take a look very closely. If you can see the icons or any image, there will be a minor problem. This is because of the lamps inside screen. Some of them were broken and it is very easy to replace. If you cannot see anything on the screen, there'll be some problems with inverter board. If you have soldering tool and want to fix it by yourself, check the caps first. It may cause this problem. Some caps might show leaking or burn spot on the board because of too high temp. If you don't have soldering tool, you better go get a technician to do so. Hope this help!! If anything I can help you with, feel free to let me know.
Thank you,
