SOURCE: Toyota Corolla Verso 2004 CD problem
I've now fixed two of these units and they both had identical problem and solution.
The problem was an intermitant fault, that after a random time, would result in a noticable snap and a failure of the sound system both radio and cd player.
Solution:- In both cases this is diy fixable with just some screwdrivers and a soldering iron.
First remove unit; this is done by unsnapping the two trims that house the face air vents this then exposes the fixing screws 2 at the rear 2 at the front, remove screws then theclimate control facia ,this allows the unit to come out far enough to unplug all connections both to the hazards ect and the radio unit.
Once out, remove the radio lid and the facia housing the controls, this just snaps out of retainers that you systematically release with a screwdriver. remove side supports marked L & R then this exposes a number of screws to remove including a small side panel that allows you to unplug the cd interface. Note ; it is not necassary to remove the cd player from facia plate. remove two screws exposed by removing control panel then remove ribbon from socket that supports lcd screen. This should then allow you to gently ease the radio unit clear of the facia plate and cd. Once clear remove all screws retaining back plate and pcb and lift pcb clear of case. Now viwed from the top and front you will see a heat sink that supports 4 big transisters , re-solder all legs of these transisters (3 legs each) this has cured the problem twice for me now. Assembly is reverse of reassembly plug in and check out those sounds,
