Question about IBM ThinkVision L151 15" LCD Monitor

1 Answer

IBM thinkVision I have a IBM ThinkVIsion monitor. I have a green blinking led. After I checked the user guide I determined that it was out of range frequency. The question that remain though it is that I can't turn the monitor on or off and that even when I change this monitor to an other computer with a different rate frequency. The monitor is still behaving the same way. What can should I do next and is it the end of my monitor? Thank you for your help anyone.

    Hi, I have a Thinkvision model 8734-ABO there is a label Grade B Size 17. The monitor was working fine till I turned it off to change a computer upgrade, when I turned the monitor back on the power light blinks, I have tried all the suggestions, even several different computers no change. If there is a card or part that can be replaced within the monitor what would I look for and where would I get a part for this old monitor? I do not have a repair sam or any other lit. on this is there any available? Maybe I should pitch it and buy a new monitor? HBEL4@Columbus.rr.com or WA8BNS@Hotmail.com

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.

Inout signal out of range Answer Failed: retry


It shows out of range because the PC is sending out the video signal that is higher than the monitor can display, you need to set the PC video resolution to the native resolution: 1024 x 768 @60Hz. You can reboot the PC into save mode (hitting F8 key while booting up) then set the resolution to 640 x 480 (try 1024 x 768 if it allows you to do so), reboot and reset the resoltion to 1024 x 768 @60Hz.

IBM ThinkVision 17" Monitor displays for 1 second then black


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.

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.

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 =)

Monitors video and power blinks on and off


Yet another case of bad capacitors on the power board.
These monitors are well known for this issue, but they live a long time past when they should.
Easy repair, but if your not confident around electronics drop it to your local TV repair shop.

Hope it helps =)
