First 2 alphabets no use-la (all Sharp Aqos starts with LE) its the last 3 digits that tells you what model - 650/ 830/ 835. Good quality and probably best bang for bucks (Cheapest?) but yellow is too strong and there is reddish tint - cannot be calibrated out, I tried already. Also screen is highly reflective, make sure you have black-out curtains else watch only at night.
BTW Sharp is probably the 1 out of 2 or 3 real LCD manufacturer, every other brand ehem S@#Y buys their panel fr Sharp and rebrand
There's no point in waxing lyrical eloquent if the root causes are not squarely identified, without subterfuges and euphemisms
