Got ahold of Alpine today, has to be sent in. $105

The buttons are removable, Ive tried removing and cleaned the contact points with alcohol and reattaching, still the same.

I've had this unit working in my truck for about a year and a half now no problems and yesterday I get in and it turns on plays fine for a few minutes then the screen goes black and I lose all sound. When I turn on my truck all the buttons will light up and I hear the internal fan turn on, also powers on my amps but still no sound or screen. Things I've checked -Inline fuse on the yellow cord (Good) -Remove the button cluster and trying the reset button -Remove the negative cord from my battery for a few mins and hooking it back up and trying to start the unit -Truck running and off with accessory -Removed the radio and plug it in to a 12 volt power supply None of those thing changed anything. Any suggestion or help is appreciated, also I did try to call alpine today (7/18) but they are in a meeting 7/17 from 3-4PT and are still not back...

Replaced my RCA's today and now I have a terrible alt whine. Never had this happen before so Ive been trying to do some research and what the problems could be. Here's what Ive tried so far. I've disconnected the RCA's and the whine goes away. Plugged a factory wire back up with factory speaker and no whine Disconnected the 4 channel amp from the ground block and grounded it independently at another point. Since theres no whine with the factory speaker am I correct in assuming its nothing behind the head unit i.e. radio antenna, HU ground Any other suggestions? Also I did remove the remove and plug in the rca's while the system was running. Just found out that this is a big no no. Im running an Alpine INE-S920HD, with a PDX-F6 & M6

Replacing this is way too pricey. Would it be repairable?

What would it have damaged amp, speakers, HU?

Well crap, I had no idea

yes

FIXED!!!! It was the drivers side rear RCA, unplugged it and full volume and bluetooth calls all work. Just going to leave to go until get a new wire and have time to replace it. Again thanks so much for all your help figuring this out

ill take a look at those thing but I have to get the truck but in a semi working order so I can go to work now Thanks for all your help shizzzon

Also it still cuts out when trying to make a bluetooth call as soon and the other line picks up, even with the mic unplugged

I have been testing with the remote wire disconnected to the sub amp. I running a a high current knukonceptz inline fuse now but when I installed a touched the wires and blew the 3 60 amps fuses. All I had on hand was a single 150 to replace with. Pulled out some old 0ga from my old truck with a different inline fuse (150) and ran directly to the 4 channel, still goes into protect. I had hooked back the remote to the deck so ill have to go out a try it jumped. Im running 0ga batt to the block and 4 ga out if it so im not sure how it couldnt be getting enough power

Also I ran just the sub amp and it went up to full volume and ran with no problems

4 ohms
