The problem I am having is my control board will short out when my kids shuts the power off in the back of the system before shutting it down in front. To get my PS3 working again I just replaced the control board and I have done this about 6 times already. I know this is a common problem but I was wondering if I need to replace something else, maybe the power supply. I don't want to keep replacing the control board. Any advice would be helpful here. thanks
