No solder mod prob?

[Valcor]

Hi guys and gals

I have had a no solder mod in my version 4 Ps2 for about a year now. All of a sudden this has started happening - the draw opens normally and after a couple of seconds attempts to shut and won't, (a sound like the draw cogs won't catch (?!!) is heard! (When playing originals the draw works normally)

Has the chip gone bad, as I thought? Has this happened to anyone else? TIA
