I think it shuts down because of the power supply overload signal from the deflection board or the feedback signals to the TDA9162 on the decoder board.

Have you seen the text strings in the beosystem software eprom?

tc0fh:

From some experiments with beosystem 2 (mk 1,2 and 3) I know that the software is clever enough to figure out what's connected and behave accordingly. The beosystem 2 (and Beovision 5) are very very very similar to the Avant DVD RF. I assume that if you remove the deflection board it will behave as a beosystem.

Only the mk3 RF DVD has the same software (latest)16.3 as the system 2/BV5 mk2 and higher.

Don't forget that the chassis switches itself off if there is any fault in the deflection/powersupply. Removing these will result in no startup.

I know (knowledgeable/capable) people who did this experiment years ago. They ended up by removing the tube and deflection and mounted only the deflection on the back of the chassis.

The idea is to use as much as possible from the original Avant (or BV3) chasis.

The beosystem 2 (and Beovision 5) are very very very similar to the Avant DVD RF. I assume that if you remove the deflection board it will behave as a beosystem.

If that doesn't work I think it's possible to trick the Avant into working without the high energy boards.

And still using the chassis?

The chassis needs some control signals from the powersupply and coils to swiths on.

So you have to fool the chassis.

Or, place a system2 chassis internal?

Hello!

Reviving an old thread...

I was thinking along this line: take a Beovision Avant or Beovision 3, get rid of the deflection coil and the rest of the high power stuff, replace the tube with a plasma or LCD, fit some glue logic inside and breathe new life to that old Beovision.

What do you think?

I'll give it a go.

all the other stuf has no function anymore, except the amplifiers.

With other stuff I meant the BD player, Pio panel and the media box.

So, I would try to leave them as original as possible which makes it easier to swap one of them.

For instance, a newer BD player which functions faster or ..fill in yourself.

I completly understand why you dismantled the avant chassis.

Absolutely stunning - It's given me an idea to use the shell of a worn out beovision 9002 with the tambour door, this is truelly awesome.

I'd recommend a lintronic box so that you use a beo4 to control all the non b&o parts.

Congratulations, an amazing piece of work

For me it is more a esthetic issue.

By exchange the avant tube by a HDTV Panel all the other stuf has no function anymore, except the amplifiers. If you like to use the old chassis and hardware it make no sense to upgrade it with a HD panel.

Also the space obtained by removing the old chassis you need for the media (HD) box and BR. Yes I agree it is no plug and play solution and not adviced to people who are not skilful. Anyhow anyone who has a good advice to integrade this components please reply.

That's an different issue you're entering. What about the warranty from Pioneer?

Maybe you will succeed, but what to others? It isn't a plug and play solution.

Ok, a stripped avant and some extra (selfmade) parts, but I also would try to keep the other equipment as original as possible.

A Lintronic device could control sound through a build-in receiver with 5.1 DTS/DD etc surround with pre-outs, and also control the channels, etcetera. All controlled by a Beo4/5.

Hi Beobuddy,

Yeh youre right I have powered the mute from the amplifier itself. That works but no controlled volume. I am using the remote of the PIO but cannot control the volume of the out. This will only control the onboard amplifier of the PIO.

I will ask for the technical documentation of the PIO and find out to pickup the signal before it goes in main amplifier of the PIO.

Hi

I used the existing amplifiers as is 4x15 watt (continue) so keeping the active crossover and feeding it with a additional powersupply. You can see it on a picture earlier provided.

As far as I can see in the manual is that pcb 10, the amplifier/cross filter board needs an active mute signal. That means only an active zero (Volt) is needed to mute the signal. Any resistor from the 20 Volt would do the job to activate the sound.

So, i.e. a mute signal from a powerlinksource could be used. (a bs3 with powerlink is suitable). With a little modification from active high to active low would be enough.

The volume control is done on PCB 14, the AV board (biggest board, in TDA7314, IC250) on the back of the chassis.

So any external controlled volume (probably line level?) does the job.

But that would then somewhere inside the pio (if you're using its remote) before the amplifier-unit.

I would want to integrate a BeoSystem 3, the difference in performance between the BeoSystem 1/2 and BeoSystem 3 is absolutely massive.

oh, i don't doubt that... but as the 8490 is basically "ready to go" out of the box, i see it as: extract the crt, plug a 15pin from the projector out on the avant (bs1) and plug it right into the back of the new panny -viola!

This would work for the US models. The EU market models don't have the VGA/projector out.

Hi, Daniel,

All of the avant, except the amplifiers and body is removed.
