'''LED #1 should always be on -''' unless the wall cord is unplugged, or, the PS is shot. That it runs for two minutes seems to point to an overheating problem. '''On a box that old your thermal paste could be shot and need replacement…''' that's a major project. I would clean out the inside of the machine… leave the back open and set up a small fan and see if it operates any longer… if it does after leaving it overnight you should run AHT and see if it identifies an overheat (or other problem). ''If this answer is acceptable '''please remember to return and mark it'''.''
