Okay, so I'm fixing up a secondhand DSi. I took off the original dead screen and replaced it with a refurbished one. Although the refurbished one will usually allow the console to turn on instead of flicking right off, it only works a small percentage of the time - usually displaying a bunch of lines. Today, when I was messing with it some more, I noticed that putting pressure on the ribbon cable clip seems to affect whether or not it wants to fully work. Basically, I'm not sure whether the refurbished screen I bought is faulty, or if the console needs a new ribbon cable clip. Is there a good way to test this? Also, if it is the latter, where can I buy it, and how is it installed? I've seen them for sale for the DS Lite, but not for DSi. Thanks!
