Hi all,
First time post in an electronics forum and I’m something of a newbie so go easy 
I recently purchased an OLED switch from eBay which had a cracked screen and a slight bend. On checking power, the Switch is taking a charge as expected but does not power on or output to HDMI.
On further inspection the board has a small crack on one outside edge and what looks like a capacitor has come loose. When testing in both continuity and diode mode in either direction on this component I get OL readings which makes me think nothing is passing through. Would it be a fair assumption that this component is dead? The crack runs under it which makes me think this is what made it come loose.
Don’t take this the wrong way bud and I hope this doesn’t come acoss in the wrong way or anything,
But in order to actually be competent and capable of doing the repair you need to have some fundamental knowledge of electronics. You mentioned above your a newbie so I’ll set you on the right path which you should proceed on, educate yourself on basic electronic fundamentals before ever even contemplating conducting any type of repair or diagnostics. (and I say this based on what you’ve wrote above)
First I’d say search youtube for a guy call “Afrotechmods” and just watch every video of his. Second stop using diode mode as a diagnosis tool (it’s pretty dumb in general), get decent tools and equipment. Following all this, search the forum to gain knowledge… While I haven’t posted info on the Switch OLED model specifically pretty much 99% of the info all still applies, and all the diagnosis methods I mention pretty well will apply to all things none switch too (generally speaking)
I could provide the answers to your specific questions above, but you wouldn’t truly learn from it… and I say this from my perspective also as I’m the exact same. Other trouble is, when people are so “young” in the knoweledge well, it leads to miscommunications, misunderstandings, a needles back on forth in order to clarify etc, which is why it’s good to aqquire the basics prior (hope that makes sense)
Anyway, hope that helps 
Awesome, thanks. No offence taken at all. At the moment I’m what you’d call “all the gear and no idea”. I’ll have a search to see what I can turn up - thanks for the pointers. I can do repairs reasonably well if I know what the issue is but my big gap is diagnosis, which is seems is half the battle
