Screen flicker upon unplugging peripherals, dissipated after a day

NECESSARY TO REPLACE ENTIRE MAIN BOARD + DISPLAY?
OSX 10.9.5 (13F34)
Intel HD Graphics 4000
I attempted for the first time to use my MBA as a desktop replacement with triple monitors: 2 external and the exisiting MBA monitor. Upon unplugging all peripherals from my MBA (Thuderbolt monitor dongle, USB external video card dongle, USB IR mouse/keyboard, and external DVD-ROM), the MBA screen started to flicker, while the external monitors went to sleep/black (as normal I suppose). After multiple MBA resets/shutdowns, eventually the flicker started to dissipate, but is still slighly present--Genious Bar appointment tomorrow. After reading some relevant IFIXIT articles (listed below), is is possible to 'temporarily overwork' and/or possibly permanently damage the onboard Intel HD Graphics 4000 with my attempt at a triple monitor MBA setup? I've read on IFIXIT of other users who get screen flicker from water/humidity damage; however, I don't believe this applies to my MBA.
Some theories I'm entertaining:
0. Loose cables (I suppose it's possible since I travel with my MBA so much).
1. Non-official AAPL device and/or bad driver
Startechcom USB to DVI External Video Card Multi Monitor Adapter
I've already unistalled the external display driver and plan to return/never use this product again.
2. Non-official AAPL device (no driver)
Cable Matters Mini DisplayPort Thunderbolt to DVI Adapter http://www.amazon.com/gp/product/B00DRK7...
I wonder if this experience should teach me to only use official AAPL products (?)
What do you think the problem is? Is there something else I should consider?
Thanks IFIXIT community!
Some IFIXIT relevant articles:
Under 'Quality Program E1', AAPL Genius proposed "replacing the main logic board and display" off-site free-of-charge. After using Time Machine to back up to Time Capsule (wow, non-AAPL external hard drives can be so unreliable), I will most likely do as he suggested, but can anybody in the IFIXIT community think of reason(s) not to?
Some possible ideas/questions:
1. I think the screen flicker is completely gone now (however, Genius mentioned that he did see a slight flicker). Possibly assume that some piece of hardware was overheated/damaged 'temporarily', but cooled down and better now. So logic is: don't-fix-what-ain't-broke?
2. Though my MBA has a SSD, does AAPL's "MacBook Air Flash Storage Drive Replacement Program" have anything to do with my screen flicker?
Thanks IFIXIT community!
Is this a good question?
