Question about Sharp XL-DV60 System
After reaching a certain volume, (usually anything after 15 out of 30) the stereo goes into "Protect" mode, where the screen reads PROTECT and shuts off, every single time. I would assume this is either an overloading issue or an energy issue, as this is a product that follows energystar standards. what would be the best way to solve this issue, as I usually set the volume to 20-25? I've set the volume up to 30 maybe once or twice and that didn't last very long, just to see how it played at the top volume.

this is a common problem with this unit the main thing is a low grade capcitor that the manufacturers used which is known to discharge all of its power at once which it recieves a high signal output and tells the unit to shut down the solution is very technical but basiclly you gave to install a higher amp capacitor.

Sharp DVD Micro Theater System XL-DV60 solution Posted by sonny.marquez on Nov 21st, 2008 at 11:46pm
I own a similar system that began to have a "protect" error message when I crank up the volume. Before you proceed, the solution requires you to open up your system by removing the top cover via removal of five screws and opening it up. So IF you are not experienced in opening up electronic equipment I suggest you find somebody who does. The error is caused by the cooling fan being stuck or not able to spin. The system has a sensor wherein, when it detects that the "amplifier" IC heats up, it spins up the fan to cool it down. IF the system detects that the fan is not spinning during the cooling phase, it will give out the "protect" message. Note that it will only spin when you crank up the volume. Less or 0 volume will shut down the fan due to it's "energy star" feature.
To solve the problem, I cleaned out the dust in the system via a 1 inch wide paint brush (haven't tried the compressed bottled air used to clean computers BUT it might do) and nudged the fan. Played the system w/o a cover and observed the fan operation and so far it has solved the issue. I plan to lubricate the fan shaft with very small amount(less than a drop) of machine oil using a syringe. If it doe not work, I plan to see if I could purchase a replacement motor for the fan...
hope this helps....

Protect mode is not something that a reset will fix. Basically it indicates that there is a problem with the final output stage of the amplifier. Normally this indicates that the output transistors are defective. In most boomboxes, the amplifier is a single IC. If you can post the model number, I can provide you with the required part and cost.

Hello, the problem of you stereo appliances been shut down was as result of a mechanism jam of the system.
The way you could do this is to open the back cover of the appliances and check for the rubber attached to the motor of the appliances, also check and see if you can adjust the mechanism if it is a disorder manner, it require a careful approach.
This will require a skilled personnel to handle this
