Philips cd880 problem

[wising]

Hello.

My philips cd880 has some problems. Everything works, the cd spinning, the display is functional and I can change track and so, but I get no sound out of it. Analog, digital and earphone jack is dead, just a little noise sometimes, like clicks, very silent. I have changed opamps to opa2604 for a year ago and it has worked perfectly sence then, sometimes lately it has just died when I have played a cd, then some funny things on the display appeared and everything were locked, I couldnt eject the cd or anything else, only the powerswitch that worked. I shut it off and after some time it was normal again. But now the audio output is dead, no sound whatsoever out of it.

Anybody who got a clue what the problem is? How I can solve it or something I could check on it?
