- Take your A3000 apart and look for bad soldering (right spelling) I've
- had the same problem in my A3000 power supply, When i got hot
- it turned off!!!, and i took i apart and one of the transistors had
- a bad soldering!. Probably the same error you got on one of the chips
- that controls the video output!!.
