A software reset won't do anything if any LEDs have failed.
You need to either test the voltages at CN9000 at switch on, strip the panel down and check visually or use a decent (300mA) LED tester to...

Re: Samsung UE40D5520RKXXU USB Problem

It should play Divx, Xvid and HD mkv, I'd suspect the NAND if it isn't, it's a D series.

Re: (uk) tesco hudl 1 and hudl 2

That link suggests it should show connected after initially setting it up then powering off the tablet, then going through the process again. Did that not work ?

Re: (uk) tesco hudl 1 and hudl 2

Reading the entirety of both of those links, the servers aren't off and they can be activated.
You'll probably find details of rooting and roms for it over on xdadevelopers.

Re: 17ips20-r9 23253538

Re: Scope and Fume Extractor

They will do the job but in a very uneconomical manner. A flat 2D image on a screen is no comparison to looking through a stereo microscope that gives proper depth of field and a second hand stereo...

Re: Remote pump control ideas.

Yes, it would be stupid but not surprising, looking at that photo.
What's the thin cream cable at the bottom of the photo if not the antenna ?

Re: Using electronics power supply as laptop universal psu

Re: Really new to this, think I messed up a board I'm working on

Re: Scope and Fume Extractor
