There’s is currently a real shortage of Hudl2 motherboards. The only method I have of sourcing working Hudl2 motherboards is to purchase Hudl2 tablets with cracked screens that still boot on eBay and harvest the motherboards from those. As some times the motherboards have other issues, this proves both expensive and time consuming, as we test the motherboard for every function and prove that they work 100%.
As a result we have had to temporarily suspend our diagnostic service, as 95% of the time a Hudl2 that won’t boot has a faulty motherboard. We will re-instate the diagnostic service as soon as we have built up a decent supply of fully working motherboards.
