MacBook Pro 2011 15 black display and no keyboard

Hello,

I’ve bought a 2011 MacBook Pro 15”, but the display screen is black.

The external video HDMI works perfectly! I’ve checked the displays LVDS cable and is was horrible. So I changed this cable by new one but the problem is still present.

Another problem is the keyboard, only the W-S keys work. No power button. To start the system I needed to connect MagSafe charger.

Does anyone have solution …

It seems to be a water damaged Mac from the issues described. Hard to tell exactly what needs to be replaced but we talk about a component level issue that’s not a DIY repair. For a non technician it would require purchase of quite a bit of tools, skills and weeks of study of schematics to get a clue on what may be wrong. All in all, a logic board replacement or a microsoldering pro would be needed to get the Mac back in working order.

OK,

But what do you think because the system is able to startup (with MagSafe) and work using an external display & keyboard this might not be so bad.

I have working sound, WiFi and I can plug in a USB keyboard and it’s perfect.

At this point it does sound like you need a new keyboard to fix that. The logic board likely has damage which will need to be fixed to get the internal display to work again.

One of the tricky parts is you have corrosion taking place which will get worse over time. So you don't want to leave this in this condition too long and you should stop using the system and disconnect the internal battery for now.

I fully agree with @danj , fact that the Mac is still working is because none of the components which seem to be involved so far is critical, in fact battery, keyboard and screen aren't. As soon as the damage will touch a critical power/data rail the machine will stop working for good. With liquid damage it's usually just a matter of when..

@ d3signz I believe I've already given my view, keyboard replacement and logic board repair or replacement. Or you keep it as is with external monitor and keyboard if that suits your nedds.
