Hi,
i can hear only the fan working. Notting appear on the LCD screen on the cdtv, and nothing appear on tv, the unit is complety dead excepct the cooling fan.
It sounds just like you blew a fuse in the PSU, the CDTV has two fuses and if you blow one the CDTV's fan will spin but nothing else happens.
open the CDTV up, find the power suply (grey box) and unscrew it (Two screws on the top), and check the fuses.. easy :-D
