Hi guys. I want to ask for your help with a stupid thing I did to my precious PSP. I tried to clean de D-PAD with a dielectric fluid. Stupid idea. The next thing was a totally unresponsive D-Pad, with the odor of dielectric fluid and squishy noise of dielectric fluid residues. I took it to a electronics repair service (because the PSP doesn't have official support in Mexico...yet). Several repairmen told me different stories, but they can be grouped in three:
- Something made from silder was washed up by the fluid, so they needed to apply a "silver inking", or something like that.
- As the buttons of the D-pad are similar to those of a remote control, they assumed the carbon thing in the plastic that makes contact with the board when pressing was washed up, so a carbon inking was necessary.
-These two options were temporary because the inkings would wear off in some time.
The guys that supported either kind of inking were confident about this procedure, and that it would endure. Additionally, one person told me that the fluid could have damaged a chip.
Personally, I think a simple cleaning would be enough. I want to ask for your opinion, which story sounds more true? I know this is more like an electronics question, but some of you could know... well, thank you for your attention.
