I have a Delphi 250 FL car stereo, and an electronics technician ruined it. It used to turn on, but now it's completely unresponsive. He resoldered the two integrated circuits marked in the photos, and now the device is gone; it won't turn on. Can you help me?
Can you show the photos and tell us exactly which two ICs were resoldered/replaced (part numbers or board labels), and whether the technician only reheated the solder or actually changed the chips?
He removed the integrated circuit and put it back in; I don't know if he mixed things up or what, but it was working until then. I had the device turned on because of the noise.
After this happened, what checks have you done on the radio—fuse, 12 V power at the connector, any current draw, heating, smell, or any sign of life at all (display/backlight/click)?
The device used to turn on, but now it doesn't turn on at all.
