Laguna 03 bought with no discs, purchased discs of Ebay, loaded and received the message 'Loading' then 'Attention' but half of the display was missing. Ejected discs and switched off. When switched on radio will not come on (previously worked fine). Clock and temperature still work, but nothing from the radio or CD. Disconnected battery and still not working. When CD inserted it ejects straight back out. Does anyone have any ideas? Thank you.
