Sounds like something is drawing too much current etc. Although from a different cause, I used to get a similar end result with an old 1980's synthesizer because the power supply's filtering capacitors couldn't buffer fluctuations in line voltage, which caused them to make their way to the control chip and cause it to freak out and power cycle; so that's food for thought. In line with that, I'd check for burnt capacitors on your power supply just in case they got fried.<br /><br />Also make sure your power supply input voltage matches your country. The sticker on my laser chassis says 220V however it's rated for 120V. Very important to get that right too. Undervolting may not damage it, though if you exceed the proper input voltage you'd definitely fry the rectifier. I'm not an electrician or engineer so take what I said with a grain of salt. Good luck.<br />(I'm surprised no one else answered this yet).Roberthttps://www.blogger.com/profile/08064845634309009390noreply@blogger.comtag:blogger.com,1999:blog-247130680149573043.post-82227803691922800432020-08-09T12:46:00.048-07:002020-08-09T12:46:00.048-07:00Hiya, my whole laser system dies including the fan...Hiya, my whole laser system dies including the fan after a two seconds of holding the test button down, then it turns it'sself back on and zero's.<br />i'm guessing it is a power supply problem. any thoughts?<br />many thanks - RichardRichardhttps://www.blogger.com/profile/01268354254674950013noreply@blogger.com
