I have a 10 year old Receiver. I have a DVD player connected and the picture does not display when the receiver is running for a period of time.

Your DTR-7.8 receiver is not 3D compatible. It does not support the new 1.4 HDMI. You have to have 1.4 HDMI and 1.4 cables for the 3D format.

You can bypass your receiver for the video though. Simply run your HDMI cord (1.4) from your Blue Ray to your Projector. Your audio can be ran from your Blue ray to your reciever.

You have a shorted component, which one will take testing and a factory repair guide.

Hello,

is your TV connected to a receiver or DVD player? I want to know so that I can detect if the fault is from the video cord that connects your TV to the receiver or DVD player.

Or, you can connect a DVD player to the TV and see if there will be any picture.

I hope you understand what I'm trying to say above. Your TV not having picture might be a fault from the display board/ic inside the TV or it might just be a bad wire connecting from the TV to DVD player or receiver.

So try to check the wires at the back of the TV, to be know if its a wire fault or not.

Good luck.

Connect the DVD player audio with digital coax into the digital audio connection as you described and the DVD video directly to the TV. Now switch the input mode on the receiver to DVD. Then switch the video output mode on the TV to correspond to the input you plugged into. Any source in 5.1 dolby digital or dts should now work properly and have picture too.

The dvd player is responsible for reading the surround sound track, and sending it to the receiver. First make sure you are playing the surround sound track on the dvd, many have a stereo track too. Next, try another dvd and see if you can play surround sound on that one. If you can't play surround on ANY dvd I would start looking at the audio connection from dvd to receiver. Are you using an optical cable? Red, white, and yellow RCA cables? Optical will transmit any sound over only one cable, RCA cables need one cable for each channel (LF, C, RF, LR, RR, sub.) If your connections are correct, is the receiver set to play a surround sound track? Is it set in 2 channel mode?

There is a video select button on the receiver. Press it and it toggles through all of the video sources. Keep pressing it until the display says video=source.

don't run you video from the projector to the reciever. just run it to the dvd and run the sound from the dvd through the reciever

This definitely sounds like a circuit board-level issue. Have you tried moving to a different input set (i.e. if you're now on the TV inputs, try the DVD or AUX inputs for both video and sound)? Just to rule out the obvious, have you made sure that it's the receiver and not the DVD player? I know that you said you powered down the receiver, but if you had turned it off by pulling the plug on the surge suppressor and your DVD player is in the same suppressor, you might want to make sure it's the receiver and not the DVD player.

If you're sure that it's the receiver, then you might want to look into taking it to a Pioneer service center to have it repaired. If it's not worth the cost to you, it might be time to be looking into a new receiver.

Hi, It sounds like your receiver is still looking for audio on the coaxial connection, rather than the optical.

1. Make sure the optical connection is between your DVD player and the LD/DVD Optical In on the back of your receiver.
2. If you have a monitor connected to the receiver to show the on-screen display, click Setup from the main menu, click Input Mode, then, next to LD/DVD choose Optical. It may be set to coaxial, analog or auto.

Alternatively, choose the input source on the front of your receiver (LD/DVD), then press Input Mode button (bottom right, near the input selector) till it displays Digital Optical.

If all else fails, reset the receiver by:
1. Turn off the receiver
2. Hold down DISPLAY and PANEL UP/DOWN buttons and press power.
3. All Clear should appear on the screen.

Use caution, however, as this will erase all the settings in your receiver.
