I've got a Tosh 36zp18 on order, but I must admit to being somewhat worried by all the problems that people seem to be having with them. Has anyone actually received a model that does not have any problems with humming, dark spots, color spots etc? I guess the nature of online forums is that people tend to share more of their bad experiences than good. I'd be interested to know if anyone is 100% happy with their purchase. Also, can anyone suggest a few quick tests that I can perform when my TV arrives to check out whether it is suffering from any of the known problems? Finally, for those that have had some pain but who are now happy, is the TV worth the hassle?
