Have TV Questions? Ask a TV Technician
Hello and sorry you're having problems.
If you grab the original Sanyo remote and press MENU, will the MENU display please?
Also if you shut the set off and turn it back on, will the Sanyo welcome screen display?
Do you need assistance with this?
Hi Anthony and welcome to JustAnswer,Thank you for the question and your patience. Should you still need assistance for information purposes only...Initially, have you tried the flashlight test? ...please click HERE.
Still, the described symptom almost always point to an internal hardware issue or more particularly, possible suspects after a review of the repair/Service Manual are:
All of the above would require that the unit be opened up for visual inspection, voltage/continuity/resistance checks, confirm faults and effect repairs.
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?
