My wife's best friend came buy and asked if I wanted this 32 inch flat panel TV that didn't work any more. She didn't want to mess with fixing it so I figured what the heck, maybe I can fix it right. It is a Sharp AQUOS 32" LC32D47U LCD HDTV that is only 2 years old.
I plugged it in and turned it on. The screen came on and said "Please Wait" for about 1 second and it blinked off but the sound still worked. So I did a search on the internet and found that these TV's are prone to have this problem. It is supposedly a loose "Driver Board and the loose board causes a bad ground and the bad ground causes the screen to black out. I tore the back off of the TV and saw 3 PCBs none of which resembled the picture-less description of the driver board I read off of the internet.
I let the parts sit on the dining room table for a couple days while I pondered what to do with the TV. Do I take it to have it fixed or do I chuck it. The darn thing looks new.
So this morning I look at it one last time and just as I am deciding to chuck it, I saw a glimpse of a PCB inside the inner metal case that holds the screen. So I started to split the case. I had to remove all of the electronics and the back half of the case to get inside it and there I found the "Driver Board". I removed the shield from the Drvr PCB (hmmm... the screws weren't very tight) and flopped the board over and saw a beautiful sight... carbon tracks on all the grounding points. I soldered jumper wires from ground point to ground point in a daisy chain formation and left a pig tail that I fed through the shield on reassembly.
After I re-installed the back of the metal case and reattached all of the PCBs, I took the pig tail, tinned the end and screwed it down tight to the metal case. I was cocky and reinstalled the outer plastic shell then took it to test out.
I said a prayer, plugged it in, and hit the power button. I was ecstatic when the set turned on and stayed on. Then it acted up a little only because I didn't have the original remote. I went to Wally-World and got a universal remote. With the new remote I was able to default all settings and get it hooked up!!
Man... what a deal! A free 32" LCD TV!!

I get all sorts of free electronics because people don't know how to fix em. Shoot the server I have at my house was free and all that was wrong with it was a bad hard drive.
