Ok, I would want replies if i were you, like not "it can be done anyway" so...
Basically, put your tv in at the same angle you have the cabinet tilted, so if the area ur putting ur tv in is slanted back, you would have to make a shelf that is angled so the tv is the same angle, like in that drawing u made, the tv should put pushed right against your bezel and plexi, hope that helps, i didnt read the whole thread, so if i repeated exactly what someone else said, im sorry.
