Hello Everyone,
I am new to this forum, so I apologise if this is a repetitive post. Part of my Master Control Panel 5000 has lost it's functionality.
The 4 very important source buttons (Tape1, Tape2, Phono and Aux ) are not responding at all, while all other buttons send IR signal and show feedback on the screens just perfectly. (Please see the picture)
I got Beomaster, Beocord and Beogram 5000 with MCP 5000 few weeks ago and everything seemed working fine (I guess) and I only noticed last night, that I can't switch between sources on the MCP. I am not sure if these 4 buttons stopped working recently or they didn't work since the day I bought.
I tried to clean button contacts with rubbing alcohol, checked ribbon cables for loose contact, but nothing seems to help.
Is there anything else I should check? Any help will be much appreciated.
Best regards, Emilijus
After a close look on the main board, I found a broken line, which did not indicate continuity. I have no idea how did the damage occured, but a simple bypass with a piece of wire solved the issue.
