In large enough amounts, everything in an LCD has value except for the bulbs, which contain mercury. To domestically and responsibly recycle them has 3 things that make it more expensive: 1) you need to disassemble the entire device to isolate the bulbs, with higher relative labor rates, 2) there is significant overhead in protective equipment, insurance, and regulatory compliance, and 3) you need to dispose of the mercury bulbs at a cost. Broken devices end up as a negative value item.
The 'ponds' in HK with inexpensive labor, no PPE, and no concern for their environment can pull in several dollars a unit from the value of the circuit boards, steel, and plastic. You can fit thousands of LCDs in a 40-foot container.
