Help needed for Grundig RPC 2500 (radio malfunction)

[tolis_athens]

Hello from Greece.
I just joined your forum and i need all the help i can get.
I have an Grundig RPC 2500 which worked great all those years.
Suddenly the radio stopped to function and i hear nothing but a FFFZZZZ and no stations all over the scale, either in FM or LW or MW.
Cassette and Turntable works great.
Its a great looking compact stereo. Please if anyone can help me email me at: [email protected]
Thanks in advance
All the best from Greece,
Tolis
