I have a problem with my CA dab tuner 640T V2. I have posted it already few days ago but didn't get an answer What happens is that it works fine for hour or so and then display starts blinking and it goes silent. When I unpluge it and plug it back on it works again but not as long as before....maybe 40 mins it that happens again. I need to turn it off again and works again for shorter time... It was on top of my amp (840A V2) for a while and it got very hot and that was when it started. I put it somewhere else but it still does it. I know is a overheating problem and it looks like it is damaged permanently. When is colder in the room it works longer on hotter days only about 10 minutes. Now, my question is: IS THERE ANYWAY TO REPAIR IT? DOES ANYONE KNOW WHAT IS ACTUALLY DAMAGED? Does anyone know where should I take it (in london)? I need tuner but don't want to buy new one as this one is only over a year. Can this kind of damage be sorted at all? PLEASE help Thank You!!!!
