My Yukon's infotainment screen never turned back on one morning. I found some talk about this issue but none of the quick fixes worked.
Symptoms are: No audio whatsoever! No screen display at all, not during startup, normal radio or anything, usb ports no longer have power, bluetooth does not connect and OnStar doesnt work. Even the HUD says "audio muted". What's different from other posts about blank screens is that my backup camera still works normally and I hear absolutely nothing.
I have checked all fuses I can find including the 20amp in the passenger dash panel for the radio. I have disconnected the battery for an hour and even over night for giggles. I have also tried the blue (micro usb) plug on the HDMI module behind the glove box.
I understand there are at least 3 different items that could be bad/faulty; the radio module behind the screen, the HMDI module behind the glove box or the amplifier under the center console.
Any help to even narrow it down is greatly appreciated!
