Advertisements Tivo HD boots to gray screen. Any suggestions on what might need to be replaced based on the pictures? Other info: 1tb my book external drive is attached. Power went out last night, My APC J10 worked seamlessly to provide backup power. I needed to save some of the power for other devices, so I later unplugged the tivo. (I have unplugged Tivo several times of the years with no issues). Power came back on and I plugged in Tivo and it would just boot to gray screen (I tried this several times). Unhooked all connections, opened it up and took pictures. Hopefully someone can help with suggestions!
