Dear Sir/Madam, Hope you could help me with the problem I have recently with my MD System, model ZS-M30. The display function is not working, it doesn't show any information when I play music or radio. No track information or chanel information. I have read the manual but can't fix the problem. Hope to hear from you soon. Many thanks for your time. My email address: karen3t@yahoo.com.au with kind regards Karen
