The most likely cause for this is a damaged or defective flexible ribbon cable that connects the LCD to the camera body. This will require disassembling the camera and LCD unit to repair and can be done fairly inexpensively. However, it's not really a user serviceable problem and should be done by a qualified service technician.
My name is Rick and I'm a professional repair technician with over 20 years in the business and have repaired many of these. I'm semi retired and work from home with little overhead so I can keep repair costs low. If you decide to have the camera repaired, please click HERE for a directory listing that suits your needs.
