Okay here are a few photos snapped with my cell phone of what the monitor is doing maybe now someone can shed some light on this issue.
Okay seeing everyone is pointing to the install (which I think is BUNK but I digress)
I have a DWW-700H Monitor there are four wires on it need to know how other people have theirs installed?
(My first issue with this monitor is the manual, the block diagram and the wires themselves all have different installation instructions.
In the home I hook up the hot wire the black wire which is labeled as acc to a 12v power supple and the two thinner wires both labeled ground to ground and it worked in the car it doesn't work worth a dam it works about 1 our of 20 reboots and has a ton of other issues (see my post under the newbie forums titled “major monitor issues”
I got a Pm from digitalww they think its my install (which I don't believe) I can't think for the life of me why good solid wiring properly ran and attached would cause the issues I am having I have tested the wires my power doesn't dip below 12.2v when cranking and I have tired both with and with out a PO Load controller the stats on the monitor state it will operate between 10.8 and 16V my ground is good I have hooked my DVM up and pulled twisted and yanked on the wires and gotten no differences but I am willing to jump through a hoop and say "MAYBE" (yes its a BIG MAYBE, something is installed wrong but if that is the case how can you install 4 wires wrong and have it work flawlessly 1 our of 20 times?, but the same hook up worked perfectly on a DC power supply?)
This is a call to anyone else with this monitor look at your wiring and let me know how you got yours to work.
Take 5 mins out of your day and tell me how you have your monitor hooked up if your response is the first with the correct answer I’ll pay you 5 bucks for your time (not much I admit but if you were local I would buy you a beer for helping)
Okay on my installl I have the following
Black (labled as ACC) is hooked to the 12V switched wire that the radio would normally hook too
Red is hooked to the battery
Green and gray/white both labled as ground are hooked to ground
anyone able to shed some light on this? how about if I bump my offer to 15 bucks just to take 60 seconds and look at how you have your DWW-700 hooked up.
With the cold weather coming around now I have experienced the same sort of problem but I KNOW that my problems are related to the screen being cold (even though it is well within the operating tempatures).
In the history of my screen, I've only had the white picture once. I had to turn the car off, turn it back on for it to work. Every morning it is below 50 F I have to warm the car up before the screen comes on. No big deal.
Now, to your question. I have the ACC and the 12V wires hooked to the power together so when the car is on the screen is on. I have a mazda and the 12v that goes to the radio is switched.
Now, the other two grounds I think I have connected to each other and directly ground to the car. I just took it in to get some tires on it and I'll have it back in a couple of hours.
your ACC wire is the blue ignition wire.
Your 12V is the power.
The reason I have both my ACC and 12V going to my 12V from my radio harness is because the blue ignition wire is dead when I tested it. The 12V wire in my harness cuts off when the car turns off. I know you may think the wiring is wrong... but it isn't.
Thank you for you time in this matter I have updated the photos here
home.comcast.net/~jlipchitz/lcd.htm and the black wire is clearly marked as Acc Digitalww has confirmed that to be correct and that he has gotten a few monitors with this issue I will be sending it back and I am sure it will work perfect when it is returned to me.
