Question about IBM ThinkPad 770 Notebook

IBM 770 screen blacks out sporadically

I have replaced the littel circuit board and indeed the entire screen assembly, only to still have the screen intermittently black out for no apparent reason. My ten year old daughter discovered that closing the screen halfway and restarting will get the screen to work fairly often. I need to fix this one if at all possible, no money for a nicer new laptop.

If you have an external monitor, try plugging up to that to see if it is an LCD screen issue or if it is a video card issue. If the monitor does not show the same symptons then it is the LCD screen. If it does then it is the video card. Usually the motherboard will need to be replaced if it is the video. If the screen, then it will need to be replaced.

Hope this helps!!

My screen suddenly went black, but still have sound and can work the remote.


Your Screen? Have you a screen in front of you always? Strange indeed !!!!!
Back - light problem. Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis.

To some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement. To some models sets, the back-light inverter and SMPS section circuit will be integrated at its main board itself. If so; the main board should be replaced.

Olympus C-770 camera not turning on


The switch may be going defective, or the circuit board that it is sitting on is defective. This would require factory level service. They will most likely change the switch assembly to get the camera working properly.

Screen blanks sporadically


This could be a video issue or a screen issue. To determine which one try to plug it up to an external monitor. If it does not black out on the monitor then it is the screen. If it blacks out on the monitor then it is the video component of the motherboard. In that case you would most like replace the motherboard.

Hope this helps!
