Calion,

Quite good instructions. However I needed to get to the power supply, and most of this was very useful, because there are 2 screws supporting the power supply you need to take out with the uper cover removed and the fronf left corner moulding removed. But step 14 and 15 are not necessary, and some of the cable disconnections are not needed.

On step 2 also showing the support damper (removed) with an arrow showing the hook on the back of the support damper would have saved lots of time as I had great difficulty with this step.

Thanks again

Ian
