Stuck in standby

Try resetting by leaving disconnected completely from the mains for 2mins. Throughout this time frame keep your finger pressed on the power/standby button.

Sounds as if the software is corrupt. Try a forced software update...

1) Switch the digibox off at the mains power, so no lights are displayed on the unit
2) Press and hold the BACK UP button on the digibox (not the remote control)
3) Whilst holding, switch the digibox back on at the mains power so the red standby light is displayed
4) Wait approximate. 10-20 seconds for the remaining 3 lights to display, at which point you can release the BACK UP button
5) Allow the digibox to download the latest software, which can take 10 minutes before returning to standby
6) Leave 60 seconds then power up as usual

A software update/refresh will leave your recordings intact. You won't lose anything.

If this doesn't solve your problem, then the next step is more drastic. It's a Full System Reset and Planner Rebuild. Be advised though: Your recordings are at risk!

1) Switch your digibox on
2) In sequence, press on your remote 'SERVICES > 4 > 0 > 1 > SELECT' (this will access the hidden menu)
3) Select the relevant option (usually the bottom two) and follow the on-screen prompts (note that it's likely your digibox will reboot between processes)
Applies to Sky+HD Digiboxes only, running latest EPG
1) Press Services on your remote control. 'Options' in the Top Menu will be highlighted in orange.
2) Press the Right arrow once to highlight 'Settings' in the Top Menu.
3) Now press the Down arrow once to highlight the 'settings' tab in the Middle Menu.
4) Press 0, 0,1, Select on your remote in quick succession. The 'Setup' tab will then be highlighted within a hidden menu.
5) Select the relevant option and follow the on-screen prompts (note that its likely your digibox will reboot between processes)
Sky Digibox Planner Rebuild / Full System Reset (if stuck in standby)
Applies to Sky+ and Sky+HD Digiboxes only

Same as above, but applies if your digibox is stuck in standby and you cannot get to the hidden menu:

1) Switch the digibox off at the mains power, so no lights are displayed on the unit
2) Press and hold the 'right and left arrow' buttons on the digibox (not the remote control)
3) Whilst holding, switch the digibox back on at the mains power so the red standby light is displayed
4) Wait approximate. 30 seconds for the blue Sky+ ring of lights to display, at which point you can release the 'right and left arrow' buttons
5) Press 'SELECT' on the digibox (not the remote control)
6) Now the system will format the hard drive, the blue Sky+ ring of lights should spin backwards
7) Allow the system to format, which can take 10 minutes before returning to standby
8) Try to power up!

Could be an open internal fuse or power supply failure

have you looked at power supply as you might have to change the caps on the power supply

Television is not the main remote control from behind or the side

Your unit maybe on protect condition that why on standby mode,,,it means theirs a truoble in circuit inside that why happened...try to consult in the nearest service cnter or a wll trained technician,,wish you luck

try either pressing the reset switch or disconnecting power to the radio.

Did you check the casing for a reset button (sometime it an itty ***** hole)
Hope this helps
Trap

Turn the power off and back on at the mains. With the machine now in standby, press and hold the "Play Mode" and "Minidisc Play/Pause" buttons together. The machine will enter test mode and the disc should eject. Switch the power on and off again at the mains and the machine should be back to normal.

Are any of the buttons not making a click feel when you press them like maybe one is stuck?? You didnt say if the same thing happen with the radio as did with the cd. If it is then a switch is stuck or bad or a problem with the switch matrix for the Microprocesor . Only way to trouble shoot this is I would use a scope and check all of the matrix {ie scann lines as well as input lines for distortion or noise and make sure when the buttons are pussed that they change and switch accordinly. If they dont then the processors bad. Good luck
