Hello guys, I have an pny gtx 770 with problems on 1 bank of ram. After desoldering the ram chip and measuring the pads, Byte 1 and 3 data lines are ol and no voltage drops are observed and ohms are maxed. The likelihood of all the data pads having a bad ball connection to the gpu core or the traces damage is low. I just want to confirm if this is a result of a damaged memory controller on the gpu die.

Hello,
Here I have the mentioned tablet with motherboard s6000-mb-h401. The tablet won't turn on, no display, charging normally. I manage to connect to UART port and got this output when I try to start it:
...Code:[PWRAP] pwrap_init_preloader [PWRAP] pwrap_init [PWRAP] _pwrap_init_sidly [Read Test] pass,SIDLY=0 rdata=5AA5 [PWRAP] _pwrap_init_sidly [Read Test] pass,SIDLY=1 rdata=5AA5 [PWRAP] _pwrap_init_sidly [Read Test] pass,SIDLY=2 rdata=5AA5 [PWRAP] _pwrap_init_sidly [Read Test] pass,SIDLY=3 rdata=5AA5 [PMIC_WRAP]wrap_init pass,the return

Hi, somebody knows the thickness of thermal pads for M15 R1? Or if someone have this Alienware model, can take measure for original thermal pads. -
Hi all,
i got a A1466 logic board for spare parts but it looks like the SMC ist bad. I got several spares but somehow i was too fast while removing it and ripped some pads off. You can see the damage attached.
Just for experience i would like to restore the lost pads but before i start (haven't done this before) do you have some hints or tutorials how to do it?
As written i want to improve skills so it doesnt matter if it takes longer. -
Hi!
A friend of mine gave me a dead PS5 to look at. I am totally inexperienced, but when a damage is simple (i.e. failed DAP41 on PS4s, etc.), when replacing just the IC and the other very common failing parts of these consoles, problem is fixed. So I checked the voltage of the PSU - none was present. Model is ADP 400DR. I have a bunch of spare parts around, so first thing I did was to replace the IC DAP 053 (they seem quite expensive, so I put a replacement unit - TEA2016AAT. When plugged to the power outlet, 12V did come present.
So I reassembled the PS5 and pressed the power... -
Hello,
This is a Roland MC-505 synthesizer I bought used years ago and 1 of the knobs was bent.
Eventually it started 'ghost editing' by changing the parameter of this knob on its own.
I resoldered the 5 pins on this knob (the two larger solder spots above these 3 smaller ones is for the same knob).
Then it started happening again, or maybe the knob stopped working totally (I set it aside months ago and forgot about it).
I bought a replacement knob/Potentiometer but when I recently opened it up, it seems the previous repair...
