The state very quietly passed a law about a year ago banning televisions from the trash, in part because of all the lead and other toxics in them. One still sees TVs put out on the curb, but I've noticed the trash haulers often adhere to the law now and don't take them.
There are several options for recycling televisions and other electronics. One is to drive out to one of three Mercer County recycling events this year, the first one being March 10. A friend sent me a link to Best Buy's offer to take all manner of TVs, whether you bought it there or not. That might be the easiest option, if you're out at the mall anyway.
Princeton Township accepts computers at its location at Witherspoon Street and Valley Road, but by appointment only, and no televisions. The Mercer County recycling website may be of general interest, since they handle all curbside recycling in Princeton.
Note: Here's another friend's suggestion if you're headed up to Ewing. "I confirmed in Jan. 2012 that the Goodwill store in Ewing (1628 N. Olden Ave; 609-392-2865) will take all sorts of electronics for proper recycling, including CRT-based TVs and computer monitors. The Donation Center is open Mon-Sat, 9am-8pm, and on Sundays (check hours)."
