National RF-B65D
 

My RF-B65D has become non-functional. When I first power up the radio everything is normal but after 30 seconds or so the receiving frequency starts wondering around (like sweeping around the band). I think it is happening for all bands although it is very obvious for FM (with known strong stations around). I can't control the frequency via the buttons or the knob. Has anyone experience this before or maybe can guide me on what to check?
