I got a 17 inch ibm and when i turn it on it shows the logo and then it goes black. i took it apart and everything seemed to be ok. I was thinking maybe the LF 4a fuse may be gone. But if thats not the case how would you go about this , like how would i test the capacitors or anything. I hope you can help me my grandfather is on my case right now.

skeltonh, Have you connected your L170 to a different "known-good" PC that has ALL power-save and screen saver modes disabled? Have you connected an old monitor to your PC to see if it will act same way as the L170? 12fixlouie
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.
This seems to be a common problem with these monitors. Have a look very closely and see if you can still see something there. From there, either send it to get repaired, or, if you are handy with a soldering iron, open it up and replace the 4 main capacitors (at least one of them will be "popped", but it is handy to replace them all.
In order to open the monitor, you will need to remove the stand, and make sure you get all of the screws out before attacking it with a screwdriver.
I have 5 IBM monitors at work with the same problem, and opening them up has shown the popped capacitors.
Again, only recommended if you know what you are doing. Screwing it up will leave you with nothing.
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.
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,
