Did you ever get round to checking board 45?

I will check board 45 when the guests I have over leave... my project space has been re-tasked

DVDude:

Motors are fine... that was the first thing I checked.

DVdude did you check board 45 as above? Make sure you measure across the IC pins if you usually ground the negative to take measurements. Make sure machine is on or press load [cd/tape] while measureing too!

Also I think the manual states 14v not 15 sorry.

Board 45 (upper middle display board), have you checked that there is a 15V supply across supply pins 2 and 4 of IC 2 or 3?

Are the motors on the BeoCenter OK?

I just got a Beocenter 9500 today with the same trouble with both doors will not open.

I brought it to Dillen so if he does not post here I will do so when has had a look on it.

ok re-checked the fuse on the heathsink.. when idle = .3V when active = 28v. I also swapped out PCB 62 from the 9500 with the one from the 9000 and still no movement on the 9500, yet the board works just fine in the 9000. Also the board from the 9500 works just fine (doors open etc) in the 9000.

so I am still scratching my head on this one.

It is the one on the heatsink, so you have the right one! .3 volt is much too low, it should be around 23 volt. Check F3 on the PCB behind the transformer, otherwise the problem is almost certainly in PCB62 (regulator PCB behind the CD-player). It could be the relay on this PCB.

the one on the heatsink. I can check the other...

On which PCB are you measuring actually? There are two F2's in BeoCenter 9500, one on the PCB which is behind the transformer and one which is on the PCB which is mounted on the heatsink. Which one have you checked?

I get a reading of .3V

What voltage do you get on the fuse when the BeoCenter is switched on?

Re: Beocenter 9500 door issue

Fuse is good, relay is good. still no movement.

Check fuse F2 (T1A) on PCB60 (rear PCB, coordinate F1). This might be broken.
