When I turn my dvd player on, the volume will lower on its own to almost mute. It is hit or miss weather or not the unit will turn off on its own saying protect. All connections are good. Inside is clean....
When you've got good volume, try unplugging the speakers (only for a very short time) to see if that whining noise is still there or if it's stopped. We're trying to see if the whining is related to the low volume and "protect" or if it's only coincidental.
Try unplugging all the cables (except the power cord). Turn the player on & off several times & see if that whining noise acts the same. Also see if the player goes into "protect". What we're trying to do here is see if it NEVER goes into "protect" with the cables unplugged.
Last... try to get it to start & run without going into "protect", with all the cables unplugged (except power). Plug the cables in, one at a time, and see if plugging one of the cables in forces it into "protect". If so, there's something wrong with that cable or whatever's on the other end of that cable. Unplug it again & restart the player - no "protect"? Wait a little while, plug the cable in. "Protect"? Check the other end of that cable.
If it goes into "protect" with nothing plugged in except the power, then the player is probably a write-off, ready to be replaced (it's not very often that DVD players are worth repairing these days).
