Question about Sharp Aquos LC-45GX6U 45 in. HD-Ready LCD Television
I too have the same problem with the DC-DC board on the Sharp AVC. But I didn't spend the $134 for a replacement board (MCM or Newark).
Instead, I used the reflow technique by placing the circuit board in the oven for 7 minutes at 475F. You need to cover the plastic header connectors (about 7 of them) with foils to protect them from direct heat (and melt). Take the board out of the oven and give a little pressure on all the ICs while the board is hot. Let it cool down and voila! The TV is working again...

bryansled is 100% correct. I had the same problem, and was told by the repair shop it would cost about $500 and it was probably better to buy a new TV set. I was skeptical at first because the part costs about 150 bucks. That's a lot of money if it doesn't work. But I figured WTF, just try it. Easy to install and it worked right away. Bryansled, I can't thank you enough.
