Power supplys differ from the specification on the power supply board | Guys, this model shows a 5.2v power supply, but in reality it is 3.3v.......the 24v power supply for the Audio also shows 24v, but in reality it reaches 18v... ok. Don't kill yourself trying to get the correct power supplys because it's a PCI manufactured for other models and the screen printing on the card doesn't match the model in question | MIGUELTV | |
