I do at $750 plus shipping. Or send me your board to test first before you spend the money.

I checked the boards and the horizontal deflection board has some burn on the back.
If i swap a working one in the Cine9 could this be damaged too ?
I think the burn must happen due to the fan fail in the middle because the board get very hot in operation ?!
Board is: R763140
thanks

The horizontals boards go bad, period. And if the middle fan did not operate to cool a heated board, then that could be something to look into. The horizontal boards runs very hot even with the fan in full operation, so its hard to say it failed from fan failure, unless the fan failed to operate.

Hi Mike,
thanks for your input here.
Can overvoltage cause problems too ?

I did a test with a good working horizontal deflection board from a 909-er and put it into the Cine9.
I got the same behaviour no HV.
Maybe it's the quad ?

Another thing which is strange.
After pressing the main power button on the back of the projector switches
on. Normally it should be on standby and only powers on when the remote button will be pressed.

Not if the auto-on function got enabled in the menu. You really need to start swapping boards back and forth between your two sets. There's no point in guessing. Since you have two sets, swap boards one at a time. Once the set fires up, you've found your problem.

A quick update:
I swapped the whole tray from the Cine9 (not working at the moment) with the controller...to the BR909.
All worked fine that means the tray is working fine. I also did projector diagnosis which gave me no errors.
Next step i did was the swap of the EHT board:
Barco Cine9 with good EHT from BR909 there seems to be HV (i heard it) but no light output on the tubes
(shutdown after 50 secs).
BR909 with "old" EHT from Barco Cine9 not working and no HV.
After swapping back the good EHT board into the BR909 the projector works fine again.
Both projectors DO NOT WORK with the swapped EHT boards !
If the quadrupler is maybe dead would it bring such a behaviour ?
thx
ElTopo

You can try to swap the quad of the BR909 (that works fine) into Cine9.

Here are the error messages i get when putting the tray with the controller into my BR909.
It looks like the EHT has issues ?

No, that just means at some point in time, the EHT had failed. THose errors remain there until cleared out, they don't reset once the problem is repaired. Same with the fan fail message.

What would be the behaviour of Barcos in general when the
vertical board has a failure? No high voltage?

What would be the easiest way to check if a fuse has blown ?
Thanks

Multimeter and check for continuity.

I post this every once in a while, and I will again, no offense to ElTopo.
I can appreciate that everyone on this forum wants to save money, but in a case like this, PLEASE let a professional tech look at your machine, or send some boards out for servicing. There's no way that you'll be able to repair a problem in any CRT projector if you don't already know how to check a fuse. THe 909 is probably the most complex CRT projector made, ask guys like Mike Parker or any other tech that has ever worked on one. Parts are VERY hard to get for them, and trying to solve the problem yourself is not a great idea. If you try and repair a 909 board yourself, and make it worse, I personally will not try and repair the board.
ElTopo, you've sent me about 3 emails regarding prices of modules, and yes, they are very expensive compared to other CRT projectors. Again, parts are very hard to find, and my prices are usually 1/4 to 1/10 of what Barco charges for new boards. I'm happy to sell you boards, but you're going to be far better off sending me boards to test and/or repair rather than trying to guess which one is bad.
With your posts above, I have no idea whether you have an image or not, whether you've narrowed down the problem or not, but to dive into a complex machine without knowing how to test a fuse is asking for trouble.

Multimeter will arrive tomorrow so i can first check all the fuses.
Ordered also a brand new quad to check if the old one is bad.
@Curt: I'm still interested in the horiz defl board but first i wanna check the HV section.
The controller tells me 1600 hours on this puppy 
cheers

And this is why I'll only help out but so far. I agree 100% with what Curt posted above, even to the point of also suggesting that when working on this set, it would be best to send your boards to Curt, especially, since I've never really offered to do board repairs for forum members, and I'm no longer doing board repairs for the 909 or any other CRT projector.
I think the above info should be posted in a sticky or somehow that it could become known that this particular projector can require a more serious service approach than what seems to be expected from a forum. It is without a doubt a very complex machine, and with that, it can have its share of very complicated issues when it fails.
Beyond swapping out a few boards, it's the only 'modular' CRT projector that I know of that should never be looked at as a DIY project.

Mike,
thx for your reply. Curt and you are totally right.
Sending the bords is not possible as i'm too far away and shipping costs will be way too high.
I just wanna go step by step to see which board or maybe tube is damaged.
Thanks for all the input !
As soon as i know which board it is i will buy a replacement from Curt or decide to repair it @Curt.
