Question about Sony MHC-GX250 CD Shelf System

Stereo stuck in demo mode

I have a Sony shelf system that was giving to me because they said it wont turn on so they didnt want it. I looked at it and it seems to be stuck in demo mode and will not turn on no matter what button i push. The front panel doesn't seem to be responding to anything i do. I disconnected the connector thats running from the front panel to the main board, blew out the dust with a can of air and reconnected it. I've done the same with all the connectors since it was pretty dusty inside. Plugged it in and tried to turn it on and get nothing but the demo.

Any Ideas what could be causing this? I was thinking that the AMP board could be bad, or even the front panel board, but im not sure.

    I've done some asking around and found out that the memory chip on my stereo needs to be reset. I followed the steps from the manual to reset the radio by pressing 3 buttons. No luck! is there a way i can do it manually? or a site where i can buy a replacement front panel board? or where ever the chip is located. Its 2 main boards.

    Thanks.

Sony CMT-EP515 CD Shelf System. CDs wont play. Place CD in tray and close, disc doesnt spin but 4 distinct clicks heard then nothing


It could be 3 things.
1. the Laser carrier may be stuck and may need to be gently pried from centre to outskirt and back.
2. your cd spinning motor has gone and needs to be replaced,
3. your laser carrier motor has gone and needs to be replaced,
hope it helps.

Powers on but CD shelf seems to be stuck?


we both have the same issue. Probably with moving it around, the CD system got pulled down. I fixed this by opening the right hand side wall, with the system upright, and shoved it towards the ceiling. Then I flipped it to the side and loaded the disc, and it worked. Make sure you disconnect the power before anything.

How do i open the cd tray on a sony mhc-rg70av shelf system that seems stuck


Most CD trays will open if you shut off equipment and pull gently but firmly to overcome the slight initial resistance. Don't use so much force that it seems likely that the tray mech will break. This calls for a serious bit of taking apart and is best left to the local repair shop.
