Hi guys, would like to ask if anyone has solved "D-PROTECTION" for LG surround system, MODEL-CM9940.

My sound system has been working realy great for almost a year.
Ive been really carefull with all my connections to speakers and is in a well ventilated area.
My surround systen was not used for about a week.

Last week was working great then switched off power and disconnected it from main power. (Never disconnected speakers)
Wanted to use it today and D-PROTECTION showed on the display.

Let me know if anyone solved this issue please, or let me know where to buy new part.(PCBOARD etc...)

I have a background on electrical and airconditioning circuit boards.

Thank you all in advance and please email for any information.
