Question about Canon LV-7240 Multimedia Projector

1 Answer

Our club owns a Canon LV-7240 which has worked OK. Last night we showed an NTSC DVD from Europe and no red showed. We could see what the colours ought to be on the laptop screen. On the big screen, though, red was black, orange was yellow, and purple was blue. This was using a non-Mac laptop and the VGA cable that came with the projector. I took the projector home and tried it with a MacBook Pro with an adapter cable in addition to the projector's VGA cable. It worked fine. I tried to figure out why one of the colours hadn't been projected using the other computer. I could not activate the part of the menu where one can choose image mode, brightness, contrast, etc. It was grayed out and the only part of that part of the menu that worked was Color Screen, which was off. According to the manual, there should be sliders and a number next to Brightness, Contrast and Sharpness, but there weren't. I was doing this just with the projector, with nothing else connected. I tried using the menu with video, s-video and both computer settings but the menu looked the same with all.

Can't answer for the menu issues, but I can garuntee this is not a problem with brightness, contrast or sharpness, and very unlikely that you'll find a solution in the menu. What is likely is that the VGA wasn't plugged in properly initially. When the signal is going down the VGA it's broken up into 5 seperate signals, Red, Green, Blue and 2 sync signals. What is likely is that the green and blue pins havn't properly made contact either inside the projector or inside the laptop. This would also explain why it worked when you tried later because it made the connection properly. I would suggest trying again with the same laptop, if it does it again, try another PC without moving the projector or the VGA connector that's plugged into the projector. This will atleast narrow down your problem, but it doesn't sound like a problem with the projector to me. Also try plugging the laptop that wasn't working properly into a monitor (this will test the laptop)

I have a ntsc copy of spartacus it will not play on my lg bd550


Hello
There will some writing mistake on your copy I should say. Your LG has Standard NTSC colour system built in one. Standard NTSC colour system means. NTSC 3.58. If your DVD contains recordings with NTSC 4.43, an other version of NTSC, your player could not identify it. If it is NTSC3.58 itself, lead-in and led-out tracks has been burned well. OK.

I own a toshiba 19dv500 and am having trouble viewing a dvd, the system is working but only in black and white, no colour\???


Hello there,

A black and white picture is most often due to a faulty or incorrect RGB (red/green/blue) connection or cable.


If you are using a composite connection (red/white/yellow RCA jacks), you have probably connected the yellow plug to a socket labelled Pr/Pb, Cr/Cb, or Y - on either the DVD player or the TV - most probably the TV. The yellow needs to be connected to a socket labelled "VIDEO". If you connect this to any socket labelled Pr/Pb, Cr/Cb, or Y, you will get a black and white picture.

If you are using a component connection (red/green/blue RCA jacks), one of the plugs is either not fully inserted into the socket or is in the wrong socket. If you remove any one of the R/G/B plugs, you will get a black and white picture.

If you are using a SCART cable (UK / AUS), you may have a bent, damaged or disconnected pin.

I suggest you check and correct the connections between your DVD player and TV. If you are unable to locate the problem, please try another cable as the one you are using may be damaged. If you are still unable to locate the fault, please let me know the brand and model number of the DVD player and how it is connected to the TV. If required, I can also draw a diagram showing the correct connections.


It would also be useful to know whether this "fault" suddenly occured, or whether you have just connected the player to the TV.

Hope this helps - please let me know if you need further assistance.

Regards,
BElectric

My lv-x2 cannot run with the red colour - it´s dead! How can I get the red colour back?


It was not a problem of the beamer, but my notebook has a loose VGA-plug. I fixed it by slipping a handkerchief below the plug. Thus I could carefully lift the plug in order to reconnect the cable. The colours are just fine now!

Functionality in Europe


Hey taliadoros,

According to the manufacturer, this particular model appears to allow filming in NTSC format only. Unfortunately this means that in order to play any video footage recorded on this camcorder, the device being used to play the footage back would also need to be NTSC-compliant.

Please keep in mind that while some electronics sold in Europe may be both NTSC and PAL-compliant, it cannot be guaranteed that footage filmed using your camcorder will be compatible with all multi-format model devices.

Hope this helps you out.

Sincerely,
Aaron
