ok made sure the lead is correct one. pulled all the cards out and still no fans or anything else.
only led that is lit is the AC led. the 120v led isnt lit.
not sure where the video lead is, but will pull it when i work out where it is :D.
pace is on my wish list but not sure what it is or what it looks like so if anyone has a link to one i would be grateful.
the PSU on ebay would be an option as last resort. obviously i would prefer a uk based one, but would get one from states if no other way.
i have also checked the switches and they seem fine. checked the voltage switch and that is also corectly set to for uk voltage.
i am sure once i get it going (with your help that seems more than likely :D ) it will prove to be a great bit of kit!!
i would also love a hp scope as and when funds allow, but unfortunately the wife insists we feed the kids first so it will have to wait untill i have some money :S

As suggested, remove all the cards and see if the supply will come up. It could be something simple. Are you getting an overvoltage or overcurrent light?
Just to check, is the voltage switch correctly set?
We'll get you going, trust us ;)

Subject: [hp_agilent_equipment] Re: possiable power supply fault hp16500c
thanks for all the sugestions!! it will take me a little while to work through them all, to answer the question on test equipment avaliable, i have managed to gather a few basics, so i have a fairly good DMM its not a fluke but its a pretty good tenma, i also have a DSO a rather old but trusty gould 2 channel 150mhz. i also have a temp controlled soldering station. and a bog standard spring loaded desoldering pump.
i will look into the transformer as that seems a sensoable idea to have one anyway. if someone is willing to have the supply sent to them to look at it for me and would like a pattern generator in return ;) :D .
i will have a go at the ideas posted so far but i think its best i refrain from desoldering lol. i will post later to update on progress :D
i must say i been on the net for years and never come across such a friendly and helpful bunch before! i feel at home already!

> first my tale of woe....i wont bore you with all the details but basicaly i was stupid and brought privately a hp16500c, i drove 250 miles to pick it up (met the guy in a carpark!! first big mistake), and purchased what i belived was a fully working logic analyzer. ok yes it was stupid.got it home and it's dead!!! not a single sign of life.i had a 2 hour flap and panick then downloaded the service and read it a couple of hundread times (ok maybe 10-12times) i have checked the leds and it appears the 120v led dosnt light. so am i right in thinking that its the PSU thats croaked it? or are there other things i can check.
> i would realy love to get it working as it took severn months to save up for it!! if it is the PSU is it possiable to get a replacement or can theese be fairly easilly fixed by an idiot?
