I was given a 52in RCA HDTV and they said that it had a 3D image. When I plugged it in I couldn't get it to power on so I replaced the bad fl231 convergence fuse that was causing the 3D image but I still can't get it to power on. After replacing the fuse I got the power button to come on and all it did was flash until I unplugged it now it won't do anything again. I checked the fuse and it's still good so I'm now lost with this thing. Any help would be great
