We have a built in Concertone DVD,CD, Radio player. I have read that this brand is notorious for failures. Went out for a five day trip and the darn thing just wouldn't come on. Power button had no effect at all. I unscrewed the unit from it's mounting place and checked for any loose wires but found nothing. Any body have any thoughts about what could be wrong? I am strongly considering replacing this thing, can anyone recommend a different brand that might be of higher quality?
