Thank you. I am still trying to get it to work but each time I remove the APU, more solder pads are weakened. This will most likely be my last attempt to get it right.
ok, listen carefully: there are 5 pairs of test pads that goes from apu to the screen connector. they are located top side left corner of the apu, right side of the emmc, right below the screen connector. there are 5 pairs of golden test pads. you can see if they are connected to the apu by simply check in diode mode. if connected you get a reading and means that the balls are connected from apu to the board. and the problem is elsewhere. my readings for these points are all the same 0.23 you can obviously have slight variation but you need to see a value. if not the apu ball had some issue and is not attached to the board in that specific line
apu balls size are actually 0.35mm. the stencil say 0.2 only because when used with solderpaste the balls are 0.2mm when they are completely formed. i think...
you didn't check the screen connector. only because you work on the apu it doesn't mean you can exclude a possible damaged connector. you know those are fragile and problematic, especially when you assembly various time in a row. if the console boot is ok and you need to focus on the connector
@@joseramonmartinezmedina1174 you need to check the backlight circuit first. on the lite version are more frequently the problem of "sound but no image" problems
Nice try, seemed like it was close to working.

I understand. I will verify when I am finished with work. Thanks for the tip.

Ahh, that makes much more sense. I noticed that when I put the .3mm solderballs, they seemed smaller than the balls from solder paste.
It's been a while since your last video. I am not pushing for another video, I just wanted to say that I hope you are ok.
Doing good, just super busy with work. Going to try and record some videos soon. Thanks for checking in.
@@probablycantfixit6426 It is good to hear that you are ok. I will keep an eye out for future videos.

I have a similar problem, it sounds but no image, need to check the screen conector (or replace it) before to buy a new screen

@@RVNR2022 I did, I have backlight but no image
@@joseramonmartinezmedina1174 ok then. Screen connector is the next step
I did replace the screen connector (did not record) as I had that same thought. It did not help the issue.
