Pls guys.I am very mentally deranged for this player.What can be the problem with this damaged parts.The front display is dark ,the CDM4/11 is OK on one other Philips,but on this can`t work.The front panel control buttons don`t work
May be the problem is only in the PS.From where I can start to repair this player,if anyone can give me any info for the read points on the PCB,service manual for this or any other useful info for me
Thanks

Hello,

It is probaly the power supply. First of all, you must replace the broken parts. But take time to mesure if there is any short between 5+ and ground. If it is, the new regulator will blow. Another thing, if the powersupply has Ic-fuses, mesure 'em. They look like a transistor with only two legs.

Best regards,

Magnus
