I have a Philips WAC700/5

Question

I have a Philips WAC700/5 which, when switched on, will not progress past the booting up stage. I have tried a couple of fixes already (checking the robbon connectors and a firmware recovery) but no joy. Just prion to this problem the unit stopped in the middlt of a track after about 1`0 minutes play and on both occaisions could only be resolved by switching off and re booting. On the third re-start it would not go past the booting up stage.Any ideas?
