CD 10

Philips CD 10 Portable

 

 

My CD 10  reeds  the  T.O.C.  quickly but the audio is distorted

 

Whats inside

 

Someone has been here before missing M1.4

What is this for ?

The Block diagram, is a CDM 2p player with TDA5708 and TDA5709 , the rest is Sony , its a “PhiSo” player 😉

Lets check some Signals

I don’t measure -0.4 ;-( its around 0.9 volt

PLCK is not the 4,3218 MHz its 4.248 Mhz and not stabiel

Some service notes i found

Oh no, Flexfoil traes apart ,;-(

Quickfix

Troubleshooting

No connection between D1 of both processors , so no Power of/off to the powersupply

Mainswitch off the player , and processors controlled power on/off for +5.2 Volt en -5.2 Volt
