After replacing Q802 set will play normally for 2hrs-4days. I used original factory replacements. This board (EMH502) has just been rebuilt by Tri-State. Before I send it back for warranty repair, would like to be sure the problem is on this board or somewhere else possibly. Has anyone ran into this problem?
