Vaio flip notebook screen flickers

Out of the blue, my sony vaio flip 13 model 2012 (SVF13N13CXB) started doing this :-/
In 2013, just a week after I bought it, the machine suffered from random and frequent shutdowns. I RMA'd it back to Sony and they replaced the motherboard. Then, the touchscreen started making contact with the keyboard, resulting in random sleep wakes and key-presses. And then, the mouse pad's left side sunk into the body of the PC, so I had no choice but to fix it manually. After that, the fan made a grinding noise, so I ordered a replacement and fixed it as well. I have a handy way with electronics, But NOW THIS HAPPENED. And I guess it's a hardware issue, but I need some troubleshooting guidelines about what is actually wrong, and how could I fix it myself. I have no spare money to invest in a shiny new Vaio or Surface Pro since I've gone back being a student (academic nursing school n'****), and the special abilities and versatility of this puppy are absolutely crucial to my day to day life (my whole notebook, as is my life, is digitized on ONENOTE. When it works it really is second to none...
Any help would be immensely appreciated :-/

[SOLVED]!!!
some important updates on the situation: turns out that this seemingly catastrophic failure was caused by a software incompatibility issue. To be more specific - it was MY OWN inconsiderate borderline retarded behavior that jeopardized my precious PC. I got greedy and stupid, and installed a pirated game that apparently was bundled with a corrupt directX or something, which totally shifted the system toward instability. a long story short; I managed to troubleshoot the source by sorting to the last line of defense, i.e booting to SAFE MODE and hoping to god that the flickering daemon will not present itself there. I must have done something right in my past life, because the all-encompassing karma spirits decided to grant me this one and call it a day with driver issue only. I uninstalled the Intel graphics driver with DDU and booted into a normal and stable desktop. Hurayyyyyy ))))))))))
