Color LCD viewfinder

[Fred Purdy]

I posted this question earlier in another forum and probably didn't get read by anyone who could help. My problem is; the viewfinder will not display an image, it just displays a white field with vertical blue lines. I can connect to a monitor and see and record what I am looking at but can not get a picture in the viewfinder. This tells me that the problem must be in the viewfinder itself and not elsewhere in the camera. Am I correct?
There isn't anyone around that has a XL1 so I can't swap viewfinders to to verify that it is in the viewfinder. Is this a common problem and does anyone know what to check and a fix short of replacing the viewfinder?

First case I've read about an EVF problem like this.
The EVF has a number of different circuits from the analog outputs. They are both in the EVF and in the body.
Check to be sure the plug is in fully.
It is possible that a ribbon cable has worked loose inside the machine.

Just dug out my trusty mothballed XL1s to double check a couple of things, so, here goes...............

1. Remove the EVF plug from it's socket and check all 12 pins in the plug are present and straight. They are very easily damaged. If ok, replace firmly into socket.

2. Power up the camera. On the LHS lens housing module you'll find the "EVF Display"/ "On/ Off" button. Whilst checking the viewfinder screen, press this repeatedly - does the picture change? It scrolls through about 4 or 5 differnt options then returns to wherever it was.

3. Below the above mentioned button you'll find the "DE/ Bars / Select" and "On/ Off" buttons.

Press the D.E./ Bars Select" button once. This will put the camera into "colour bar" mode".

Press the "On/ Off button once. You should now have digitaly produced colour bars in the EVF.

If you now have bars, there is a problem with the camera internally. If all the above produces nothing it could be anywhere.

4. Last but not least: Flip the EVF up and over so you have access to the underside. You'll see a release switch on the LHS to release the lens housing, and a rubber bung on the RHS with a triangular "lightning" mark above it.

Remove the rubber bung and, using a NON METALIC (GOTTIT?) slot driver, rotate the enclosed potentiometer to the full extreme of anti, then clockwise, all the while keeping an eye on what the EVF is doing (does require some contortions but can be done).

It is possible this has been turned up to max or min and thus rendered the EVF unusable.

Best I can do I'm afraid.

PS. Whatever the above turns up, the way forward, given the age of the XL1s (if you wish to keep using one) is not to get it repaired (not sure if Canon is still doing them anyway) but to buy another system S/H. They are coming onto the market in increasing numbers and are pretty cheap. Just cobble the best system you can from the two and away you go. I would do so with mine if I hadn't gone completely HD.

If you can find the pinouts, you can run the video to another monitor. This was not all that uncommon when some videographers did not like the low resolution EVF.
