Can you please get me the model number found on the back of the set ?
Hi Elle and welcome to JustAnswer,Thank you for the question and your patience. Should you still need assistance for information purposes only...Initially, the described symptom almost always point to an internal hardware issue or more particularly, possible suspects after a review of the 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 a soldering iron?
On "...woulnt know how to take radio out of car..." please click HERE for instructions on how to remove the unit.
...and HERE on the dis-assembly of the DEH-P3150
Appreciate your kind understanding Elle.
I realize that the above information may perhaps be not what was expected. Unfortunately, there is no quick-n-easy fix and neither is there a workaround; sorry for having to be the bearer of bad news.
Good luck Elle and thank you too for the opportunity to be able to share the information
Great Elle! Good to hear that the issue has been resolved, congratulations.
