I bought a BUSH WS6680SIL television 23 months ago and the colour has failed - can only now view, acceptably, in B/W by turning off the colour selector. When selector is on, bright pink surrounds a centre of green. Have written to BUSH Customer Services who have basically said, unlucky, can't help, out of 12mth guarantee, get in an engineer etc. Surely a digital television should last more than 23 months? I did point this out to them, no response. Help, anyone, please?
