The protect mode is an indication that a problem was detected in the final stage of the amplifier. In this particular unit, the final amp stage is within a large "amp-pac" IC attached to a heatsink. This will be marked STK402-xx. This particular IC has been changed to provide better performance and longevity to a different variant. The cost for this part is around $60. While I can not state for sure that this is the problem, this is the most common failure part for the symptoms you have described.

Hope this helps,
Dan

This is a circuit inside the unit that is proventing the flow of eletricty to the rest of the unit so the amp does not blow. without looking at the unit I could not tell you what blew or what part is effected by the protection fault. However any tv sterio repair shop would be able to look at this and let you know if its worth the fix or not.

Thanks and please do leave positive ratings and feedback for your free answer today.

My sharp cd-ba 1700,has protect on screen.how do i remove.thanks


The most common failure is of the internal Amp IC for these units. See the link below for a generic explanation of protect mode. I believe that the amp-pacs for these are still available and are in the $45 range.

My sharp cd BA150 is in Protect mode. What can I do?


The protect mode indicates that a problem was detected in the final stage of amplification and the unit has shutdown to prevent further damage. These units use an AMP-pac part number: VHISTK40270N1 which is available at tritronicsinc.com for $53.09 plus shipping.

Protect error


The 'Protect' error means there is a DC voltage present in the output section(which should not be there). This can be caused by a defective output IC(the big IC on the heatsink). Disconnect the IC and see if the error goes away.Also check the resistors around the IC.
