Good mornig
I have a little problem with my DVD Avant Controller; before recapping wasn't able to read the DVD TOC, after recapping it reads dvd, start executing but after a couple of minutes the image freezes and the controller starts to jump over dvd chapters. Tried using a cooler spray over the IC on the pcb but nothing change. I have no idea what to do and a new controller costs much more the whole set itself.
Could someone give son hints? I exchanged the controller with another from Philips donor but it seems to be an "autentication code" by the controller and B&O interface PCB.
I have no idea how to solve the problem :(
Regards in advance to all the helper :)))))

What did you change? Which capacitators? I have bought a few lasers for the Avant and I am just in the project of replacing one :) Perhaps I should have a look at the electronics also?
Beolab 50, Beolab 8000 x 2, Beolab 4000 x 2, BeoSound Core, BeoSound 9000, BeoSound Century, BeoLit 15, BeoPlay A1, BeoPlay P2, BeoPlay H9 3rd Gen, BeoPlay H6, EarSet 3i, BeoVision Eclipse Gen 2 55", BeoPlay V1-40, BeoCom 6000 and so much else :)
Hi Michael
I replaced all capacitors in the controller board (also called MONO board); there is no reason to replace them if the unit works correctly. :)

Hi NoBit,
I did not even think about doing that. Is it one of these boards that you mean?
Number 2 is the controller

I´ll take a look at it today. Did you have bulging capacitators on yours? I have two Avants so I should have a look :)
No I didn't. Consider that the bulging surface is the LAST step of a capacitor decadence. Before that there is a value variation and internal resistance increasing value. ciao ciao
Maybe you have a dvd controller for me :)
Thanks for the info! :) I am not super familiar with the electronic components on the boards but I try :). I have two units because the first DVD failed, and now I try to fix it so I can sell it or use it in another location. The new one is also starting to behave a bit odd on DVDs.I did order a few lasers and I think that the problem lies in the laser at least partly. You seem to have had success replacing the caps but perhaps that is not all that is necessary.
You are welcome!
