I recently got YLOD on my ps3 (60g fat) system ,sent it away ,got it back with a new mainboard ,it worked for about 2 days and it cut out (red lights blinking) once again i sent it away ,got it back and it cut out within a few hours (red lights blinking again ) ,so one last repair i sent it off to same shop ,and once again it worked for about a week then cut out on me again ! ,is there any possibility its my power cable to my ps3 thats doing this ?
It's simple: Your PS3's hardware was too damaged for it to be repaired, or the repair shop has no idea what they are doing. Not all PS3's can be effectively repaired. And even if someone gets them working temporarily (as in your case) they can shut down again almost immediately. See if you can get a refund or at least a partial refund. You need to give up on that PS3. It's beyond repair.
Could be your household voltage is blowing the Motherboard try getting a low voltage transformer it plugs into the socket and lowers the voltage because most household voltages are set to a specific Watt so it can run big things like T.V's Microwaves etc. I see you are in the US so it rules out the possibility of a broken fuse. When it cuts out do any of the trip switches trip on the main electric panel? If so then your only option is to buy a transformer. I would ask the shop where you take it first though. Hope I helped
