Question about Audio Players & Recorders
Hi, I have this system which has worked fine for a while, however I am now having a problem. This system has a main remote control sensor that if is not plugged in renders the system usless as you cannot use and functions which are all done via remote control. This is where i am having my problem whenever i plug this part in it shorts the hole system and will not let me turn it on. If I un plug this I am able to turn the system on fine but cant do anything with it. Is this a protection circuit problem???? Thanks for any help.

SOURCE: system keeps sayin protect
The word PROTECT appears because there is a short. It can be in your speakers, try running it without the speakers plugged, or look if the wires arent shorting. If it stil ldoes that, its cause there is a short in it, from the output section. The system does that to prevent from damaging the electronic components inside.

The one I troubleshot had a bad 4700 uF 25v capacitor next to the dc connector on the main pc board. this dc connector cable runs from the rear cover of unit(the rectifier board).When I power up the unit,dead,no standby lite no power.I removed all connections to cd board and just left the mmain board and display board connected.clock and standby came on,but after about two minutes the 4700uf 25v power cap started to smoke (and dmm read 12v and falling across cap).hurray that was my big clue! Replaced cap with a gang of 5 1000uf 35v nichicon electrolytes in a parallel L package formation to fit the realestate of old cap and allow cover closure.happy tunes.Unfortunatly made by cheapos who spec counterfiet electrolyte formulated caps.Watch out for "S.I." brand electrolytics.Check temp of rest of caps while running unit as this beast is chock full of them.
