Sega Mega CD Jp front loading problem

[raggio252000]

Hi!!!!!

I have a non working Mega CD Jp first version.
The system starts normally but there are some audio problems and when I put the disc into the mega cd doesn't load 

You can see my mega cd and the problem here:

I tested it with a megadrive 2 jp,all cables works great,cd perfect without signs.

What can I do?

Thanks in advance

Inside the tray model MEGA-CD you will find three circuit boards:
Digital board + connection board: The MEGA-CD itself with it's bios and memory along with the connection to the Mega Drive
Analog board: Contains power supply circuitry and audio digital to analog converters (two of them) and audio amplifier/mixer
Drive board

I'd like to mention that dry electrolytic capacitors can cause both problems. I once had audio problems on my old MEGA-CD (same kind as yours)
and by replacing all the capacitors I got the audio back and a boost on read reliability as a collateral (It was still reading discs back then but it was pretty dodgy before the repair.)
