Sounds like you are really having some woes with your TV. Now I can't promise anything but here is the phone # I called (the one with the very helpful service tech, read my posts on page 26) 321-953-5294. I spoke to John. Now this all started from a Samsung service request # for me so they already had some info on my situation. Again I can't promise you will get the same level of free advice I got but it is worth a shot to steer you in the right direction instead of piecemeal replacing part after part. If you get a chance to speak to them be very specific as to what your problem is and they may be able to help.
