Broken Djm 450

My Djm 450 stopped working after just 4 years of use. Apparently its a broken motherboard and Pioneer doesn't take any responsibility for their product. I've been told £90 just for them to have a look at it. Its a shame as I used to be loyal customer but now feel let down. Looks like they don't even try to look after customer. I thought I would share my bad experience.
