Generally I've had no or very little luck soldering surface mount devices. Generally I just try to replace the board. Most of this newer stuff seems that either you change the board or trash the unit. Of course with cheap foreign made junk, generally you use it for a few years, it quits, and then you junk it for a newer "more improved" model. Just look at the cell phone industry. Most phones are only kept for 2 or 3 years (if that) and trashed for a newer model. Although I have a cell phone, our landline gets more use than my cell. Plus a landline is dependable, no dead spots, poor or dropped connections. Well so much about that. As far as the Samsung 50 inch, I ordered another power supply board, and should get it this week. I just hope they don't break this one in shipment. I'm still taking a chance that this will fix it.
