Question about Audio Players & Recorders
I am getting PROTECT sign on displays and it is not doing anything so can you please help me out.
my sharp cd ba-1700 just stopped working displaying the word protect, now i can do anything with it, it turns on but within second it turns of with protect! can u help plz
Without a brand and a model, best that I can provide are generic possibilities:
1. unplug the unit from the mains for a couple of hours. This is supposedly to reset most systems; and/or
2. check the speaker wires and make sure none of any bare wires are touching each other.
If your concern has not been corrected after completion of the above procedures, pls post back brand and model.
Hope this be of initial help/idea. Pls post back as requested, how things turned up or should you need additional information.
Good luck and kind regards.
Thank you for using FixYa.

Generally speaking, an amp protects itself from heat, shorts and overloads by refusing to turn on or stay on.
Overloads can be from excessive periods of high output and shorts would be wiring issues or a speaker blowing up.
You should be able to feel if it's hot. WHY is it overheating? Make sure it has sufficient ventilation on all sides and that vent holes are not blocked by dust balls. Ensure the fan (if equipped) is running as designed (some only operate on demand). Clean dust and debris from it.
If the amp comes back on after cooling, you're lucky. They only have so many self-protection cycles in their lives so continuously resetting or cycling their power without addressing the cause can do more harm than good.
If it protects immediately on a cool power up you should disconnect the speaker connections and try it 'naked'. If it comes up then diagnose which lead(s) are shorted. If it does not come up the problem is internal and should be left to an experienced hands-on tech.
