Question about IBM ThinkVision L170 17" LCD Monitor

2 Answers

IBM ThinkVision 17" Monitor displays for 1 second then black

Light stays green - display is good for about 1 second then black. Rebooting/ shutting off power doesn't help. Swapped out the monitor and the other one works fine (same cables - no config changes). Any ideas?

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.

    I can see 2 large PCBs one is the power supply board with the inverter for the backlight and the other is the display logic and LCD driver.

    Are the 4 main capacitors on the power supply board? And are they all the same value?

Lenovo 9227ac1 comes on then goes black light on front stays green


When it have this kind of error is a problem of the power-board.
Anyway you must open it and look at the all capacitors and if are them inflated, if them are inflated must change them.

But can be a problem with inverters... control the transistors - MOSFET on the powerboard.

Good luck!

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.

Check the DVI connections on your computer and your monitor. It is possible that there is not a good connection. Do you have access to another working monitor? If you connect a different monitor, and that monitor comes up, it could be the DVI cable or a bad monitor itself. If neither monitor comes up it could be a bad video card or port, or the computer may not recgonize it under Properties, Display, then settings when you right-click on the monitor, if you are using it as a second monitor.

Make sure the monitor lead which goes behind the computer is in correctly and has not come loose.

Unscrew it from the PC and put it back in again.
