where can you sell truck loads of broken plasma tvs and lcd all flat screen

Check with your local tv repair guys...might not get those prices for them...but they generally will buy boards out of them for repair parts they mark way up. Same for ebay...do a search for "model" parts and you can judge what they bring. In many cases, if you work with a repair guy you might can trade out some of your broken stuff for parts or labor to fix some of the other ones you have which you resell for way more money than you lost sonce now the tv works....ie $100-150 vs the $10-20 he might give you....talk with them and wotk a deal.
