I have attempted all sumed very few reflow processes, and i need to make it better, how do you make yours to have sureness that the balls are really fully reflowed? My temptation was always to do "the slight move" touching very gently an angle, but due to some cases, but maybe 100%, where the previously half working device became totally shut off, i finally understood that the damn "move" makes the balls shorted, so what do you suggest?
Thanks!.. Muchas gracias..... -
So if you have been following my urine odor saga with my new PC, I believe I finally found out what is happening, my Northbridge heatsink is getting quite toasty, and other people online with my motherboard say the VRM's get hot as well. That may be the source of the odor I am smelling.
Current setup
The case has 3 fan openings, a 120mm front, a 120mm side, and a 92mm rear. Currently the only fan installed is the 120mm front. The CPU cooler has a side mounted 92mm fan on it (and that cooler is very cool, CPU temps are great). The only exhaust is from the PSU

So I bought another main board from eBay and the same thing happened.
I got the firmware file from the Sony website. My model was listed and everything matched.
sony_tvupdate_2011_4027_aaa_auth.zip was the file.
Extracted to a folder: "sony_dtv0FA10A01A0A1_00000301"
with file: 00000301_07e8046a.bin inside.
Loaded it into the root of an otherwise empty USB thumbnail bought from around the same time as the TV. Not too old, not too new.. under 2Gig.
The file reads perfectly. Lots of "disk activity"... -
