|
|
Is thier a manual way, non electronic to move the raster on a Barco 701s. Using Guided setup and an external or internal pattern I cannot center the red raster left to right. Its stuck very close to the right side of the tube.
Thanks

No, but pull the black connector between the deflection and focus board for hte red tube (next to the red H yoke connector. )
That will disable the electronic shift control for the red. If it centers, then that H shift/focus board is bad.
You can run the set with that connector off, but then you'll have no center red shift via the convergence controls. I can fix it though.

Just a heads up. I haven't had time time to try your idea yet, but wanted to add more info that might help.
When going through Installation or guided setup and it prompts to center the raster, neither the green or the red has a horizontel adjustment. If I push the directional pad horizontally the red or green raster will only adjust vertically.
If I need to send a board to you. Guide me through these steps and can you give me an estimate so I can budget for it.

Are you talking about the projection angle setup? That is supposed to be where you do the horizonal alignment by aiming the CRT's. There are two screws above each tube on the lensblock. Loosen them and move the CRT to align the crosshairs horizonally.

No Curt I know how to move the tubes left to right to match the green tube center thanks to you:). What I'm saying is when you look into the lens or remove the lensest he red and green raster is too far to the right. The green centers by using the cross pad on the keypad. I can move green raster electronically up, down, left, and right. The red and green will only move elecrtonically up and down. So both are way to close to the edge which is causing allignment issues in convergence and unusual artifacts in the upper left corner on the screen. For example the red tube displays a spike of red on the upper left of my screen. Its almost like the red and green are to large. Sorry for the poor explanation.
