Noob need Help! slim with no video no video reset no recovery no controller sync
I bought a 120GB slim that had no video. The system powers on and gives all the expected beeps when I do the button presses for video reset and recovery(safe) mode, but it never outputs any video and will not sync with a controller over USB (the controller does appear to charge). The hdd activity light flashes a few times immediately after power up then nothinig. The fan test works. The warranty seals were broken so I assume it had been opened prior to my acquisition. "I have been googling and searching forums for info but most info is speculative or does not seem to match this case. Can anyone give me some advice on how to pinpoint the fault, or possible solutions. I was thinking of using a JIG and trying to load the latest OFW to see if that would fix it. Is that possible with the system in the current state? I would love to get this thing working!
