Why I ask is I don't see such at any of the repair shops. All the folk I know call then dead and gone.
I have the well publicised black screen problem, almost certainly caused by the ATI graphics chip.
I have the system stripped down and have tried heating up the graphics chip as advised. With power on the board and the screen reconnected, I still have the black screen. This could be because I have been too cautious heating the chip, or I have overheated it. ( I don’t have a proper soldering heat gun so have carefully been using a modified electric paint stripping gun!). If anything I suspect that I have not applied enough heat, so as this is a s**t or bust job I will try a bit more heat in due course.
Other than the above, I have couple of problems on which I would appreciate advice:
1. There are two long leads, black & white from the right hand side of the screen that go through to the chip side of the mother board. Possibly microphone? Each has a small plug/socket which appears to connect to one of the soldered points , but there is no indication which ones?
2. Although there is power on the board (the CPU & graphics chip were warm without the heat sink) with the memory in and the hard drive plugged in, the hard drive does not start when the on button is pressed. Any advice on which connectors I might have missed?
There are plenty of videos on YouTube on disassembling the 625, but few on reassembly and these are mainly on mechanical reassembly.
Grateful for any advice.
