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.

by sancho76Hi, somebody knows the thickness of thermal pads for M15 R1? Or if someone have this Alienware model, can take measure for original thermal pads.

by dbuergiHi 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.1 Photo -
by supravit2000Hi!
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...1 Photo -
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... - Loading...
