I'm the director of A/V at our church, and we had a Sony PC-1271 switcher donated to our church. We do not have the projector that apparently is designed for it. All we have is the switcher and the remote. We've tried connecting our computers up to it, sending the main video output 5-wire to anything. We cannot get any signal to come out. (resolutions from 640x480 all the way up to 1080) Do we need to set some jumpers inside it? Does the switcher work with anything, or does it need to be connected to it's projector?

Every single manual I've found online for it is actually the manual for the projector, which mentions that you can connect the 1271 switcher to the projector.

Any help would be very appreciated.

Similar model.

Can you post a picture of the BACK of the switcher? That would tell us which cards you have installed.

The monitor out is going to my LCD preview monitor, and the input is coming from my laptop... and the power... I would think that that's all there is to it.

Thx for the quick reply, by the way!

Ok you have a good model there. Very clean.
The block on the left there is a line doubler. You have the three video/svideo inputs and one 480i/576i component input ( this will NOT accept an HD signal by the way) I have the same model. It's great for watching TV or VHS, LD, BETA any of the older formats. The output is equivilent to 640x480

I can see you figured out the rest of the cards are RGBHV/VGA inputs.

The one thing you can try here is to set the "remote mode" switch to 1 and the "single second other" switch to single.
You do NOT need a Sony projector to make these work. I use mine with a Sony and an Ampro and a VGA monitor.

Those input cards should switch any VGA resolution through them. What resolution are you running?

Thx for the input. I've tried many resolutions:
640x480
800x600
1024x768
1280x1024

16bit and 32bit, and my laptop will only output 60Hz

I tried the switch and knob you mentioned, in every possible config, and no luck. The RGBHV/VGA cables I'm using I grabed from where I work (an AV company) so I know the cables are good. When I plug my laptop straight into the LCD, it works.

Everything about it acts like it should be working, however, I still get no output to my LCD monitor... My computer won't let me send a signal to the extended desktop if I unplug the cable going from pc -> switcher, but as soon as I plug that cable in, my computer recoginizes it as another monitor.

You think the output board might be bad?

Hmmm good chance it could be. I belive Curt had some of those for sale a while back. Drop him an email at curt@curtpalme.com.

See this link: http://www.curtpalme.com/CRTforSale_Misc.shtm

He has the 1270 switcher chassis listed for $50. Maybe he has a spare output card you can buy.

Does anyone have a working model? The person who donated it to us said that we have to put the jumpers on the boards back to the defaults. So if someone has one that is working, and feels like pulling it out to check the jumpers on the output board and input boards, that would make me happy.

It's also possible for the H and V cables to be reversed on one of those interconnecting cables. Try swapping around one of the pairs. As Analog says, the switcher should pass all of those resolutions no problem. Also make sure one of the cables isn't bad, that's common as well.

Also, if you get it running and aren't using the line doubler module, list it in the buy/sell section. There's a bunch of people that would probably be interested in it.
