Hello. Some time ago I gave my Philips CD 304 to an acquaintance to listen to and he returned it to me not working. It said it wasn't opened. The display lights up, the dial spins at normal speed, the display says 00 llllllllllllllllll in the display and stops. At first I thought it was a power supply problem, but no. So on focus. Not again. I replace the Dac board with a working one and everything is OK. Next is measurement of all electrolytic capacitors, active elements, making new bridges on tables, inspection of all solder joints, but no change. I'm asking for help.
Unfortunately not. Having an oscilloscope doesn't help if you don't know exactly what you're measuring. Constant current modes are fine. I haven't given up.
I didn't understand the question. My English is weak. I have written what happens on boot up. Thanks for your interest
I recommend that you find a service manual and read about Service Loop A. It could be a big help.
