How to remove the SEMU module from a Barco 909

Thanks Roland... :D

Connects pins 1+2, 3+4, 5+6

This plgs into J5 on the RGB Driver board R762705 after the semu is removed

I must assume that these are in and out for the SEMU. and that whilst the active part of the circuit is disabled the video is still going through a torturous route and about 6 connectors to and from the SEMU Card which can't be good.

All I have to do now is soak test the projector because don't forget I only think it is the SEMU unit that is loosing me a color.

Cleaning lenses...

Guy Kuo

Dry air blown across the lens. If that isn't enough, William Phelps described his cleaning solution....

1 drop dishwashing detergent (not soap!)
(or Kodak Photoflo if you have it)
1/3 cup 99% Isopropyl alcohol
1 2/3 cup distilled water

It works very well indeed and does not harm the lens coatings. It's dirt cheap to make to boot. Cheap enough to use on your car windows. You won't believe what using an optical cleaner on a car window will achieve. Windex is residue city by comparison and should NOT be used on your projection lenses for fear of the ammonia dissolving the anti-reflection coating.

Don't get overzealous about cleaning. Every time you clean the lens, you will create some minor scratches. In other words, clean when cleaning does more good than harm.

The above solution can be misted on and wiped off with a soft lint-free cleaning cloth. Use each portion of the cloth only one pass. Start at the center and work outword. You will need to lightly buff until dry or else there will be visible residue.

Another cleaning product I very much like is Formula MC-1. I was turned onto this by Steve Smith. It leaves absolutely the cleanest lens surface I have ever seen. Use as a last step. Just a few drops do the job. The lens will appear to fog over as this dries. Buff the "fog" off and the lens will be cleaner than it ever has.

In either case, never never grind dirt back into the lens. Remove as much dust as possible with dry, compressed air. Very very lightly dust with a CLEAN soft brush. It is so easy to scratch the lens with a slightly soiled brush. Don't wipe a dirty lens while it is dry. Use a cleaning solution to loosen and lift the debris onto a clean soft lens cloth.

Be enthusiastic in throwing out multiple cleaning cloths. You're trying to preserve the lens, not the cloths.

Does anybody have a service manual for SIM2 HT300. The PSU has died and it is not an easy one to dismantle!


Established Member
Updated BG 1209s and the BD 808 pdf service manual links as they expire quickly. Download them to your hard drive if you need them as it's a PITA to keep the files up ! :D:D:D

I have a Barco 1209 / 2 and need the service documents, including the wiring diagrams. Can someone tell me where I can get this?

Thank you and greetings

Hallo everybody... and greetings from South Africa.
Our church was sponsored a Vidikron TGS 200.
Is there anyone who can assist me with any information about this video projector. Please forward documentation to [email protected].
Kind regards.
