Ive got a 2001 Acura TL, and one day the radio quit working. The display works and everything but there is no sound whatsover, I dont know if its the radio of the amplifier. A week later I put an aftermarket radio in and it worked fine, but I recently took that back out and put my stock one back in and it still doesnt work, any help? No navigation, single disk changer.

 

im having the same exact problem...i started screwing the screws on the side on the factory radio after taking out the aftermarket i had on..and when i screwed it in the screw was a lil too long and i had eveything on the radio everything was working fine and i thought bout shutting it off but didnt and then as i was screwing it in the audio went off and on and the no audio at all n the display everthing works but no audio please help!! all fuses look good buut let me know if i have to double check any fuses! 2003 acura tl s factory radio

 

My brother brought my Acura to a stereo shop today and they said its a bad factory amplifier, would cost about $150 in labor just to fix if I bought the part or can buy an aftermarket cheap alpine installed for just under $400, anyone have any ideas?
