Customer Question

My name is ***** *****. I have a sony bravia tv 42 inch but not sure of the model, picture and sound go off for 5 sec then comes back on just like when first turning the tv on, banner across top of the screen. Father in law had a similar prob and replaced power supply and resolved the problem.
JA: Thanks. Can you give me any more details about your issue?
Customer: Its acts as though the tv is turned off then turned back on but it does it by itself
JA: OK got it. Last thing — TV Technicians generally expect a deposit of about $18 to help with your type of question (you only pay if satisfied). 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.
