When viewing any source through AV2, the TV sporadically loses the image but keeps the sound. If I twiddle with the scart or knock the TV, it returns. AV1 is fine but because it's not RGB it's rarely used. It'll even happen if you walk near the set! Not always, but 70% of the time. Now I assume that the AV2 socket is faulty as every different scart I have tried has this problem on all equipment it's connected to. Does anyone know if replacing AV sockets on a television is an expensive business?
