My radio was working fine, then I disassembled it to replace the stretched off buttons. When I reassembled it, it won’t turn on.

I did not unplug anything from the back of the radio. I had to unplug a few wires to get the face off.

I double checked I plugged all the wires back in.

When I push power, nothing happens. The clock does appear. I don’t even get “locked on the screen.

Any ideas? Is there a reset?

Thanks.

Hi,

I attached two pics below showing the entire wiring schematic for the radio. Power is supplied via fuse 41 in the instrument panel fuse box. I need you to check that fuse. In addition to checking the fuse, confirm there is power to and from it. Here is a link you may find helpful:

If you look at pic 3, I highlighted the fuse to check.

If the fuse is good and there is power going to it and from it, then I need you to check for power at the rear of the radio. Power is supplied via the orange wire from fuse 41. Confirm the power is making it to the radio.

If that is good, then check to make sure the black wire with a white tracer (ground) has continuity between the connector at the rear of the radio and a known ground.

Pic 4 is a close-up of the rear of the radio. I circled/highlighted the two wires in question. If you need it, here is a link that explains how to test wiring:

Let me know what you find or if you have other questions. I have a feeling that even though you didn't remove anything from the rear of the radio, something was disconnected.

If we can confirm there is power and ground, then we will know the problem is in the radio itself. There isn't a reset for this.

I will watch for your reply.

Take care,

Joe
