I'm now going to advise generally that if you believe you have some sort of issue with the soldering of the IDE header, DO NOT try to solder it yourself, unless:

- you are highly experienced with a soldering iron
- you have a 0.5 mm, ball-tip soldering iron
- the iron is a temperature controlled, set to around 350 - 375 degrees centigrade
- the iron is a core earthed professional unit
- you are using a silver based high-quality solder, 0.6 mm
- you are using a high-quality liquid flux with non-corrosive qualities

If you are going to do this (and I would recommend highly that you DO NOT ), then please, please, please do NOT overheat the joints or the PCB pads, and ensure that you are properly earthed before you solder the pins.

Carrying out this proceedure carries a high risk that you will damage both the PCB (terminal) and the CS4231A sound chip (not terminal, but possibly so). This secondary damage can occur easily due to the IDE header being directly connected to the data lines of the 4231A data bus.

There are replacement chips available, but this chip is notoriously fragile, and is difficult to replace due to it's awkward position on the PCB, small size, and high lead density. If during removal the PCB tracks are dislodged, then the board is total loss and your player is a write-off.

You have been warned!
