I have a ceiling mounted NEC LT240K that is connected to a 20' VGA cable and a dvd player via RCA cable. I have recently had an issue with the IR remote losing functionality while the projector is in use. The most recent event consisted of powering on via remote, a picture mute via remote after an hour of use and then the user was able to un-mute. The remote was also unable to power off or select the menu, but the laser pointer functioned and the batteries were fresh. I happen to have another LT240K remote to try and that one also didn't work. I checked the menu setting that allows you to enable/disable the projector IR sensors and all 4 sensors were enabled.
The last time this happened I tried reverting to factory default and the remote worked again. I have no custom settings other than the ceiling projection and a 5 hour power down.

I see that it does have RCA input (Yellow, white, red) on the reverse of the TV. Connect the DVD via RCA cable to the corresponding color connection, place the TV in "Vido" or "aux" mode. this is usually done on the remote from an "input" button, or it can also be called "game," "video," or "aux."
Upon putting it to this after connection of the DVD player, you should see the DVD players home screen. You should be set to enjoy the DVD player.
Tries unplug,replug it back like an hour later.Letting the DVD player resetting itself back to the factory setting.Tries it than,see if it work than.Not,than tries hook it up with the RCA component cable Y,R,W.If still have the same problems,the PCB in the DVD player is bad.Not worth repairing.Trash it.DVD players are very cheap these days.U can get a brand new one like for $40 dollars.
You can with an RCA to VGA converter device (Amazon has it for $45 S&H), the AV cables of your DVD player and a pair of amplified speakers. Connect the yellow RCA video cable to this device then your monitor's VGA cable to the device. Also plug in the red & white RCA audio cable to both the device and to your DVD player. Finally connect your speakers to the DVD player ad your'e all set!
It was pretty tricky without instructions but trial & error brought me to a successful resolution. This machine comes from the factory set to connect directly to a television with supplied RCA cable. Do that before you connect to a VGA monitor. Using the remote control, press setup and then go into "preferences" and look around for "video" and then to "VGA". Once you click "VGA" the TV screen goes frighteningly blank. The next obvious step is to hook it to the VGA cable and VGA monitor. If your computer is also hooked up and on to the monitor there is no karaoke picture. Shut off or disconnect computer and presto, there it is. <br> www.texsax.com
Not sure I can solve, but maybe help. I am having a similiar problem. However, make sure you Analog Audio (RCA type) cable are connected even if using Digital connection between the two. They use those cable to send the Commands (Mentioned in the documentation).
If you did get yours to work, please give me a hint... I upgraded mine from a 603 to a 701 and haven't been able to get it to work since.
We also don't have a remote. We hooked a DVD/VCR combo to the Samsung combo by attaching the cable from the cable line to the DVD player and an additional cable from DVD to TV and it used to work but after we lost the control, the DVD can only be listened to but not seen. The VHS from the DVD player works perfectly though.
When we had the remote (before connecting the other combo) we used line-in to see a DVD or VHS using the yellow red and white cables from the Samsung to the other player.
You need to identify the four wires that carry the DVD audio in the factory plug, and re-wire them to RCA plugs that can be used with the Auxiliary input RCA jacks on your Pioneer unit.
The four wires should be:
Left (+) light green
Left (-) white
Right (+) red
Right (-) black
The easiest way is to purchase some inexpensive RCA cables (or better yet, speaker wire with RCA ends). Cut the cables and wire the center pin conductor wires to the (+) audio wires in the stock plugs, and connect the outer shield conductors to the (-) wires. Then connect the RCA plugs to your head unit's auxiliary input jacks.
