As always an excellent well documented and easily explained guide. My DSi touch screen now calibrates and works perfectly. Thank you so much for your excellent site.
I followed every step. Once I was done assembling it, I turned it on and the bottom screen flashed. Don't understand why and I'm really frustrated. Please help.
Donde puedo comprarla?
Much easier than the instructions made it seem, I'm not too experienced in this sort of thing at all and frankly I'm just glad the thing turned on once I got it all back together. Great instructions, simple repair
I have replaced the digitalizer but still the touch screen is not working, I've already make sure that all the ribbon cables are correctly connected, what could be the problem? The motherboard? I'm running out of options, any help will be really appreciated
