Customer Question

Customer: I have a Technics SX PR51. Recently when turned on the display shows on, but there are no numbers/text and no sound from the keys.
JA: Thanks. Can you give me any more details about your issue?
Customer: No, that is all there is to the problem.
JA: OK got it. Last thing — JustAnswer charges a fee (generally around $18) to post your type of question to Electronic Musical Instruments Experts (you only pay if satisfied). There are a couple customers ahead of you. Are you willing to wait a bit?
Customer: I am teaching in an elementary school today with a tight schedule. I can stay on, but may not respond quickly.
JA: OK. Now I'm going to take you to a page to place a secure deposit with JustAnswer. Don't worry, this chat is saved. After that, we will finish helping you.
