it just happend wenn i pressed the power-off key on the receiver.

The device showed four horizontal lines like --:-- like it could not

determine the correct time and showed back the channel number.

This on & off behaviour took long. I had to switch off the device

using the black power key on the back of the device when I turned

that switch back on it only displayed 'boot' nothing happend.

As I assume there is something wrong with the boot block.

but I am not sure what. I dont even know why this happend.

Can anybody help ?
