My wife picked up a flat screen TV a neighbor had thrown out, thinking I could fix it.
It sat around a few months and I finally plugged it in. Everything worked, BUT, the
front screen was cracked. I noted the stand didn't hold it up and see how it fell over and hit something.
Someone on a group suggested I sell the boards out of it.
I pulled out three PCBs and put them on Ebay, I sold all three, but I got one returned.
The one that returned the PCB was a TV shop, I think they used my board to troubleshoot
a customers TV and it didn't fix it. I still think my PCB was good and they had another
problem with the TV. But I lost money on that deal.
In the end I made about $90.
BTW, another time she picked up a flat panel TV and it worked perfectly, I ordered a $12 remote
and we have been using it at our business everyday for 1 year 4 months.
