Thanks @SS_Dave.
As soon as I softmodded the 1.1 first thing was removing that ticking time bomb! Out came the magnifying glass to check the board and it was crystal clear no leakage or expansion of the capacitor. TSOP is now complete and I have run a few tests today and all is well so tomorrow hopefully going to re apply new thermal paste and then mess about with a custom tinted jewel idea with a neopixel. Going to be hit or miss but I have a spare top shell kicking about to improvise with.
