My monitor does not turn on, I took it to an authorized apple service center and they told me they had to change the power source (sounds logical) but they added the change of "rear housing" which is a very very expensive piece, (it doesn't sounds so logical to me) they explained that the On/off switch is embedded to the housing, I don't repaired it whit them, I purchased an power source on eBay and I changed it my self, but it just doesn't turn on... How I could get it fix it without having to expend so much money?... It could be the EMI filter?
