When DVD is plugged in the red stand-by light comes on, but when the power button is pushed the stand-by light goes out and the DVD will not come on. I have attempted to reset by holding power button down for 15 seconds, the power cycles, the stand-by light comes on, but once again when the power button is pushed the stand-by light goes out and the DVD will not come on.

Hi Erickson,

First of all, thank you for posting your question here at Fixya.

I'm assuming here that your unit is Sharp BD-MPC41U.

The symptoms you've mentioned indicated that the power supply board of your unit gone to protection mode that's why the LED automatically shuts off. It will encountered once the feedback circuitry sensed malfunction and immediately turned off the unit to avoid further damaged.
To resolve the issue, you have to replaced the power supply board, part number RUNTKA699WJN0. I saw it in stock at this LINK or obtain it from your local Sharp service centers.

Also, don't forget to check if your unit is under warranty period (1 year), if so, avail it because the manufacturer will fix it for free. Opening the top cover will void the warranty.

Please let me know if you need further assistance.

Hope I helped you!

Have a great Holidays!!!
