I am also trying to figure out the best way to do the shades. Have seen that others used oxyclean, but can't figure out if they left them all gathered up (doesn't seem like they would get clean) or if not, how did they dry them and get the pleats back, so, maybe someone can give us both hints.
Our tv only operates on 110 either when we are plugged in, or if the generator is supplying 110 power. People we know have just bought a flat screen tv and replaced the old. We know some just tore the old cabinet out and the new hanger and the tv covered the opening. Others moved it to a different location and converted the old cabinet for other use. We still have our old one. Waiting for it to die. As far as the backup camera. ours is black & white also. It's fine except when the sun is shining on the camera outside, then it's hard to see. Usually the shield above it does a good job - just certain times of the day. Is this maybe your problem? The sun. For refrigerator shelves, I would just google whatever brand/model your frig is like, Norcold 1200 parts and you should get something up. I have seen them.
