Hello Tsikoteers, I am new here.

Just want to ask if my busted Pioneer DEH 7450 can still be fixed . The unit is still functional (display and line out to my sub) but no sound to my Tweeters, mid and low speakers. The only sound is from my sub.
I had it checked (here in Dasma Cavite) and they say it must be a busted chip... question is if the chip is available, where available and how much ? Is it advisable to still have it fixed or just trash the unit and buy a new one ?

Thanks
