Unit powers on. Front display works randomly, but recently not at all. Input occasionally drops from what seems like a bad connection. Sound is tinny or distorted at times. No idea what could be wrong with it. Experienced techs only. Parts & repair. Acceptable pre-owned condition with some scuffs and scratches.
