replace +3.3v point with +5v?

**Hlodvig** · 07-06-2006,10:56 AM

I have an orange dot MI (shipped from US by my friend). It was successfully flashed with 1.68 fw, but my other friend (cause he had necessary tools) soldered +3.3v to +5v (+5v connector on USB socket). It works just fine for a half an year, but is it ok? Can MI chip be fried?
Well, my MI hadn't been turning on from the first attempt lately, I have to repeat standby/switchon with my PS2 some times until it turns on...
And now... I myself resoldered this contact to right point, but MI doesn't turns on anymore...

Any suggestions and advices?

P.S.:
OMG
i've just removed MI.
Video DVD playing OK, but original games doesn't loading - i'm receiving red screen with "please insert ..."

P.P.S.:
may be i should remove NeoFix? (i have v12)...

Wow, that was a big mistake using 5v point instead of its original 3.3v. You probably fried the chip. Remove NeoFix to see if it still reads originals.

Oh, well, my PStwo doesn't read neather video DVD, nor originals anymore :-\
Don't know, is MI fried or not, but my friend soldered his chip at +5v also and it still works fine for him :-\

It's not a good idea to do that because you're pumping too much voltage into a chip that's designed to work on 3.3v.

may you friend something else as well. with the wrong voltages connected you might have exceeded some current limitations of the fuses/chips?
