Dear God.. I know this is a pretty old thread .. but WTF ! ... wana test the GPU or CPU .. like other have said hook the board up and test ... Ive been a computer tech for over 20 yrs.. Ive never thought gee could I test CPU to make sure it works b4 I put in the motherboard LOL OMG much less turn it on to test RFLOL ..
wana test it lol .. just put the chip on one nipple and hook up a lead to your other nipple .. and plug that into your wall outlet .. you will find out one thing .. electricity hurts when you dont know what your doing .. and maybe one less dumb ass in the world lol
Im a a newbie at building electronics from scratch yes .. but with all the you tube videos on xbox repair .. Ive never once and Ive seen a shit load of them seen anyone mention or try to test a re-ball with a DMM .. hell the oven trick, hair dryer, hot air gun etc trying to fix an xbox is just a temp fix anyway .. if you dont kill it ! Most dont survive 3-6 months before the same thing is happening all over again !
Only way to truly fix, is to buy the proper re-ball tools, stencil and chip clamp, board heater, and hot air or infra red rework system, this too is all over the net .. or just pay some one to do it for you 40 -75 bucks! There are some people that are just to damn stupid to drool or lazy or both lol
Forgive me father for I may have just sinned lol
