Answer to "Is there a way to fix a faulty Mac Pro (early 2008)PSU?"1: The likelyhood of the belt delivered by the smoothing caps in one of these being fatal. is at best slim. as yet there have been NO recorded occurences. if its th USA model, that slim chance is even slimmer, as the USA uses a girly 120vac as oppose to our manly 240vac in the UK. The belt itself, is a discharge... i.e it exists transiently until the caps discharge.... about half a seond. once they are discharged, they are safe. What does it feel like?

Answer to "Why does everything have a blue tint?"This, is the answer you seek: RGB components dont apply to LCD tv, so you can ignore that (liquid crytal is clear, not coloured) The Blue LED phenomenon exists in LED backlights that are manyfactured by a company called Vestel.

HOWEVER…. Consumer rights act 2015 may provide you wih an alternative way out. The TV must be fit for purpose for 6 years after the date of purchase, otherwise the company you bought it from are liable. Net result = 1 free telly.
