Alesis SamplePad - Common blue-display bricked device > seeking repair

Block Image

Polling the experts for a solution to this very common error on these original Alesis SamplePad devices. There is a history with these drum pads dying with this blue-screen failure where they are non-responsive. No error displayed on the screen, attempts at a factory reset are not successful. The vendor will not comment directly and will only send customers over to their service group to get a quote for non/warranty repairs. Does anyone have a fix or experience with this unit they can share?? Customer options seem to be either re-paying 80% of the original purchase price to hopefully get their unit magically returned in a functional state and hope for the best going forward, or discard and replace with a current model….

Any advice, schematics, or experience would be greatly appreciated.

Update (11/24/2019)

FYI: Still no luck chasing this one down. No YouTube hacks have been found and I have recently reached out to Alesis parts department about the error and their ability to identify/provide the proper part for this common failure. I also reached out to their sub-contracted East Coast service center to see if they could provide any technical assistance. (To give this private business credit, they were skilled and quite knowledgeable when I last visited with a bandmate’s gear and their store/shop was a very interesting museum-like collection of rebuilt and repaired instruments from decades past. I suspect they have also paid their due to Alesis to have the privilege of servicing their instruments… :(

I just received a repair estimate from the Alexis service center. No itemized parts, no breakdown on labor, no technical info... Just an estimate for $120. SMH.

Sorry, still haven't found the time to replace @30 caps, but I did see this video in the meantime which may be the clue for some; intermittent power jack;

It seems his issue is simply a bad solder and only showing blue screen just before boot.

Unfortunately was not my issue as in fact, my jack is also sturdily zip-tied to the board!

Same problem, I've replaced PSU capacitors with no change, next I'm going to try replacing all the rest of the caps and see what happens

Thank you Jimbomu. I would love to hear your findings. Best of luck with the teardown. I am still shocked with such a common failure for these devices how little information seems to exist around the error and resolution.

Much appreciated,

I gave up, too much de-/soldering for me - will sell mine for parts..

I did see another video meantime where a fellow discovered he had the blue-screen problem because of an apparently too-long mounting screw on the back had damaged one of the sms elements on the pcb (he did not attempt repair). Alas, that did not seem to my issue.
