I have a rca rt2580. Plug it up and i hear a click and the standby light comes on and will turn off if i push the power button. Found a blown fuse next to the power supply (5A 125V) so I replaced it. As soon as I plug the unit up the same fuse blows immeaditly. I have heard about a bad capacitor that will show signs of bulging but Im not seeing that on my unit. Also no signs of any other obivious problems. Does anyone have any clues on where to begin on troubleshooting this or maybe have had simular problem. Thanks!

Unfortunately, your question has too many variables. Try this. Unplug the unit. Plug it back in. When you first push the power button, you should immediately hear one mechanical click from the unit, followed by a second click with 5-10 seconds. If you don't hear the second click, the unit may have a condition known as DC Offset. It would be unusual to have DC Offset only within the first 5-10 minutes. It's possible that power supply has an issue where both the positive and negative voltages are not coming up at the same time.

If the system is connected properly and the main tuner power is on you will see the orange standby light on in the front of the main diamond shaped control unit. If that light is not on, you have not connected the system and power cables properly.
If the standby light is not lit, press the power on/off button in the middle of the rectangular processor/tuner to turn it off and unplug the main power cord from the main tuner/processor from the wall. Next, ensure that all of the power, video and audio cables from the diamond shaped control unit are properly connected to the large tuner/processor. Since you are there, check any other av in/out connections.
Now that you have checked and adjusted the cables between the controller and the tuner, plug the tuner back into the wall and push the power on button. Now check the standby light again on the diamond shaped controller unit.
Once that light is lit, press the silver, horizontal on button in the middle of the diamond shaped display unit, or the Power Standby/On button on your main remote control and you are operational.

I took your advice I unpluged the unit then held the power button in then pluged it back into power outlet the unit came on. There is one thing I might add I had to do it twice before the unit came on. Now how long will it work? Who knows
