Is it a clicking noise from around the PSU?

Yeas it is but its very low,you must have to be very near to hear it.I have looked on all fuses and they are ok.

Hasse,


The first thing I would do is pull the SMPS power supply and get a light and magnifying glass and check the solder joints where the two big transformers are mounted. I've recently seen two BG800 power supplies with cold solder joints (that occur over time) and resoldering them fixed both supplies.

The person who bought my old BG800 had the same problem. He injuried

it while lifting it to push something underneath. The other person wasn't

very strong(!), and it almost feel down on one side. When he tried to

power it up, it made that noise. Somehow he manages to power by

pressing the main power button(on the back) very slowly...Several times!


Oh yeah, by the way. Do you know if it's been resoldered? Several of the

800 series had this problem

I would check the caps on the SMPS. They sometimes short and that can cause that problem. I would take an ohm-meter to them (in circuit is ok).


Good luck!
