Circuit Board Help

I have a Sony hcd-fx10 dvd home theater system, and one day I turned it on and it went into protect mode. I contacted Sony and they said it needs to be serviced. I found a service manual online and took the unit apart. I consider myself handy, so this was not a problem. Upon further investigation and with use of the service manual, i found a brown burn mark on the bottom of the motherboard, which corralates to the protection detection module on the board; which is my prblem. My question is, Can I simply remove this module, or does it need to be replaced with a new one or something similar? I don't know much about circuitboards but have some skill at soldering. Attached are pictures, the best I could get of the small board, showing the actual module on the board and the burn mark on the bottom of the board. Any info would be great. Thanks.

This is out of warranty, or you've just invalidated it? I don't know baht Sony mean by "serviced" - that's what you do to things with moving parts. It strikes me that Sony didn't know what the problem was, and neither do I. Going into "protect mode" sounds like a software feature - you didn't put anything "non-standard" in there? Maybe a BIOS-type reset would fix - any batteries or jumpers in there? L

i dont see anything bad in the images. the red stuff under the board is soldering amterial left there since manufacture the chip on the cooler looks like a voltage regulator and not any protection related stuff does it say anything else on the protection mode screen ? is it copy protection / protection against improper connection of external devices / protection of improper voltages / something else ?
