Hi guys got a Corolla factory cd cassette player that was giving a lot of issues. It's from 06 Corolla, my friend the same unit in his corolla and he has the same issues.
1. Stereo restarts by itself (thought loose connection but does this on bumpy and non bumpy surfaces) ''ST'' letters would blink on off on the radio when this would happen.
2. Audio cuts in and out randomly for a second or a few minutes at a time.
3. Shows MTL ERROR (randomly or after turning it on) assuming to do with tape deck which actually plays.
4. Shows ERROR 3 (randomly or after turning it on)
5. Shows ERROR (randomly or after turning it on)
6. CD never worked pain in the butt to put it back together (broke a tab taking it apart and will work on it later.
What I've done (haven't touched my friends unit, it's still in his.car). The deck has good sound and actually has AUX-IN which is why I want to keep it. The deck has no branding and I can't find it online, it's oem and the part #s are dead ends. I took it apart and soldered dry joints on the connectors, on the back, all over the board. NOW I GOT NO SOUND. The CD and cassette parts removed still no audio. FM tunes but it is harder to set the stations than I remember? It's been a few days and nothing, worked once for like 2 mins both on radio and cassette I had audio but now silent. Dead silent no crackling, no audio cutting in and out or even resetting even on bumpy roads. I've found the schematics for microcontroller and the sound ic. Help me get sound back, thanks.
