Hi guys. I have an sp5000 that's driving me nuts. One day she just wouldn't power up. No flashing led for a trouble code. The amber power light will show...after about 15-20 seconds all the lights (buttons) light up. At that same moment there's almost a click sound from the internal speakers. And it will cycle and do it again...over and over. I'm at a loss please advise?


I've tried another power chord..outlet etc. Checked the lamp (switch) that the housing cover activates.

It sounds as if the power supply startup circuit has failed. It contains a capacitor that has lost value, so the power supply can't start. A quick way to confirm this is put the pj into a hot location for a few hours and then try it. If it starts when hot, you have the diagnosis. If it doesn't affect it, then keep looking.

I'm glad you got it fixed. It's a good ole' PJ. Finding that bad capacitor took me a week, and I design power supplies. The fools glued the cap' to a heatsink, so it ran hot, and gradually lost value. Do you think the power supply was buried enough at the back of the case?
