My MacBook Pro retina screen is dead. Screen or logic board?

I own a macbook pro retina, mid 2012. I bought like 2 years and 2 months ago.

Yesterday, I was cleaning my macbook as usual with some alcohol(95% ethanol), between the keys and on the screen. I do it regularly and it's not my first time. After a bit, the screen started flickering in a barely visible way, you need to focus on the screen to see the flickering, I directly updated mac os and restarted. After the restart, the flickering increased and it became clear. I turned off my mac for like an hour, and tried to boot the flickering disapeared, after 10 minutes the flickering got back. I was shocked, so i turned it off till the next day, once I woke up i turned it on and noticed that there were no flickering, I left it on for like an hour and came back to check the flickering was enormous, there were color change it feels like the screen was going to blow. I turned it off and rebooted and the screen was dead. Here's an image of what I currently get when I boot

i tried an external display with both vgas, and everything worked fine.

Is this a screen problem? or a mobo problem? any other explanation to the above image?

Thank you.

Note: it's an LG screen.

Moe, "i tried an external display with both vgas, and everything worked fine." pretty much rules out the logic board. If an external monitor works, your GPU circuitry is fine. Based on your image, it looks like a bad LCD. Make sure that you check your cables and that they are properly connected. Check this guide step 11. Hope this helps, good luck.

Thank you, it's still strange though that it happened after cleaning it with alcohol. the screen is LG and it had ghosting problems, I think it was a coincidence. I ordered a new screen, samsung display. I don't think it's a cables problem given that it was functioning properly and I didn't move it around or anything.
