Was just given a JVC Dynapix by a neighbour. All works fine

Customer Question

Customer: Hi, was just given a JVC Dynapix by a neighbour. All works fine but for a loud mains hum which increases and decreases with changes in the screen image. Dark is very quiet and light in very loud.
JA: Thanks. Can you give me any more details about your issue?
Customer: Not much else...it's kinda weird when you get a bright scene on a street with a loud buzz and a dark bus passes close by taking up the whole screen and no buzz while until it's gone.
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.

Hi and welcome to JustAnswer,

Thank you for the question and your patience. Should you still need assistance for information purposes only...

Initially, bear with us; re-confirm and post back with the complete model number of the JVC.

And as this almost always is an internal hardware issue, are you then considering a DIY (do-it-yourself) repair approach? If yes, do you have access to and familiar with a multi-meter and even perhaps a soldering iron?
