Buahahaha!!! Nah, keep it. She had no problem giving it away instead of repairing it - no ethical crisis in my mind.
That's kind of how I got one of my TVs. Guy said it died like 2 yrs ago and was taking up space in his garage. It is one of those Sharp LCD TV's with the tuner in a stand alone box. Got it home, looked at it closely, crud and gunk in the cable. Cleaned it up with a toothbrush and some alcohol... works like a charm!
