Re: Pulsar wont wok

Just to report. The card has been repaired. First, all the capacitors were changed, but that did not solve the problem. Now I finally changed the stabilizer and the Pulsar is now like new.
Thank you all! :)

Good luck!

Re: A communication error with Pulsar2 (brd 0) has occured.

It's not that I don't want to help you, It's that I question your ability to do the repair if you don't even know how to identify a transistor. It's really easy to do damage to the card & you may do more damage than good. All the parts are labeled clearly on top of each component, the power mos...

Re: A communication error with Pulsar2 (brd 0) has occured.

Yes. You're right, this is the one for a P2. I had a look at my cards, so here are the mosfet for P2, Luna and scope. For P2, the datasheet can be found here. https://www.digchip.com/datasheets/parts/datasheet/446/AS2815AU-pdf.php Looks like they used different schematics for voltage regulation. Th...

Re: A communication error with Pulsar2 (brd 0) has occured.

The part of the voltage regulator is the black quare part with I*R 3103S labeled on it.. on my scope card, so I suppose pulser2 is the same. You can buy them from aliexpress and you need some soldering skills to remove it. For a pulsar2 the price in germany is in the order of 200 Euros, so there is...

That's half his fee, it's a very fair offer, and keeps your keys and other investments intact. Worth considering. Ha, sorry I must have written that while i was at my parents visiting so I wasn’t thinking The price is 225 + shipping if i get it to work and if i can’t resurrect it i’ll only charge $...

Don't ever bake anything but cookies & cakes! Have you tried to replace the power mosfet transistor ? I can give that a try for you.. If it works I'll charge $125.00 + Shipping. If not, I will put your old one back on and send it back to you, all you pay is shipping. Thank you for your response...

Re: A communication error with Pulsar2 (brd 0) has occured.

I have the same problem here. I did a recap, but it didn't help. I tried on 3 different computers and it always gives the same error. The installation of the software and the driver pass normal, Device Managger shows Pulsar, but instead of Scope it always shows this dialog with the same error. In th...

Re: Pulsar wont wok

Capacitators marked with red is 47uF 6.3v The two caps marked yellow are 47uf 16v The blue mark is cleaned solder pads without a 47uF 6.3v. I have ordred parts from Elfa, and i have to double check if the dimension is correct. I can upload a video of how i recap the board next week :) The I/O plate...

I have desoldered all the capasitors on my Scope 15dsp card.
It was little tricky with the larg caps, but the smaller SMD caps are easy.
I will check my Pulsar 2 card soon.
I will post picture in this week, and a part list of caps.

Regard Kjetil. Norway
I hope everything will work properly.

If you need such advice i recomend you to take it to a technician. Honestly
I will! Thanks :)

I thought to make it easier for him. If you say that it is not complicated, then my help will not even be needed. ;)

Sorry for bothering you, :)
You could just have a little more detailed description of how many capacitors there are and where are they located?
