Question about Televison & Video

2 Answers

Pioneer elite rear projection - unit crashes frequently, making a popping sound, gets yellow/black striped screen with inward arcing edges. Have to manually turn off unit, wait a while, usually, then manually turn back on. It may then function normally for a few minutes, or a day or two, before crashing again. What's the likely cause. Thanks in advance for any thoughts on what needs to be done and probable cost.

Try to turn off the TV for 2-3 hours first, unplug the power cable. If that didn't work, there's a problem with its internal power supply chip. You may need to double check the circuit board of the TV to see any burned components. If you can't open the casing of the tv, just contact any pro tv technician to do the component replacement.

You may need the power supply board resoldered as I had the same problem. The guy listed below can do it for you as I shipped mine from Illinois to him in California... Piece of cake getting the board out of the back and it's not too fraigile... Just pack in bubble wrap and it will be fine. My TV is now working great.

Black screen pops up states caution your screen may seem reversed


I'm assuming this is a DVD player or at least contains a video screen. The message you are seeing sounds like the rear camera input has been activated. They give this alert to inform drivers that the view through the rear cam may be reversed. Most cameras have a switch setting to allow this adjustment.

If you do not have a rear camera installed, then it sounds to me like the rear camera trigger has been improperly connected. This is a wire that when it sees a 12-volt signal, activate the rear cam input on the radio. If you do not have a rear camera, this wire should not be connected. You did not give a make/model so I cannot begin to guess the wire color, but look for a wire that is not either black, red, yellow, white, gray, green, violet, or blue (with or without stripes). There is no standard color for this wire. Some Alpine units use orange/white, but on most radios, this is a dimmer wire. Pioneer and Kenwood often use a light purple or purple/white.

Find out what wire is for reverse camera and disconnect it.

Pioneer Elite Pro 620 HD TV on several occasions the screen has gone black but sound continues and the power green libht remains on. After shutting down for 10-15 minutes picture comes back.


Pioneer Elite Pro rear projection 620HD - Picture is still there but brightness and "white" have faded over years allowing for mediocre viewing when room is dark only. During the daylight picture is visible if viewed straight on and within 15 feet from set. Any suggestions?

I do not have the wiring diagram for a pioneer deh p7800mp.


If you're installing this the easy way to go is go to like walmart and buy a stereo2.gif wiring harness for your specific vehicle. This plug plugs directly into your factory plug and has the wires that connect to your pioneer unit attached to it. All you need to do is match color to color. tracing wires to splice directly into your factory wiring can be a royal pain, trust me i've done it and it ain't fun... but for what its worth here you go.
