I could be more helpful if a model number for the systems were provided, but I think I can still provide some details.
Your first system probably just needs a good calibration and alignment of the laser eye. Of course I have no way of knowing that will correct the problem, because I haven’t looked at your system, though we have a 90% success rate on all systems. Calibration and cleaning is covered under our labor of $49.95.If any parts are needed then additional costs would apply. If in the event that your system requires parts to complete the repair then a technician will call you, and quote you on the cost of the repair. If you don’t want it repaired, we send back your system and you only owe us the $20.00 estimate fee along with the $10.00 for return shipping.
Is for the 2nd system with the controller port unplugged, remove the bottom case from the system and you should be able to plug it in. When putting it back together just hold the port in the place it would normally go then put the bottom case back on.

If you wish to repair the system yourself, here is a link to a guide that can walk you through the steps:
