Some time ago I have successfully acquired an incomplete 701CS from a local marketplace for a relatively cheap price.
It had no hdd, hdd caddy, battery, faulty charger, oxidation on top and bottom boards and untouched leaking cmos battery. But I tought I need to start somewhere.
At that time I only had time to quickly disassemble it and replace the cmos battery plus a bit of oxidation removing activity, but without any place and way to test the machine actual state.
Now when I have finally found (a lot of) time to reassemble at last, stuck at a peculiar problem.
On powering on the laptop, the screen only displays a bluish-greenish inhomogeneous thing.
As it seems, it is actually displays the correct things without any contrast. It can only be seen from a couple of centimeters.

Please, anybody have an idea about this issue? I tried to reseat the lcd ribbon cable, but no change.
I have a faint suspicion of the inverter card, but without a spare one, I would like to be more certain about it before trying to buy a spare part.
Thanks in advance,

I'm pretty sure that I have already tried this trick.Thinkpad4by3 wrote: ↑Thu Jul 12, 2018 7:31 pmYou can use the Fn+Home and Fn+End to adjust the contrast(might be PgUp and PgDn, its the icon that is a circle, half white and half black.) The blueish green pattern on the screen is part of the old DSTN technology. They get burn-in and there is nothing you can do about it. All of those screen have it if they are used.
But I will definitely try it again after reassembling.
Thanks for the tip!
