I will take a look.
I know that the interconnect cable screws into the back of the screen from the input box, but I thought the other end of the interconnect was something like a quick connect - maybe that is from the motherboard to the input box. I think both you and I ordered the 5 meter interconnect cable too. I'll make sure to double check my connections again and maybe use some cable ties like you did.
Researching in the thread where you addressed come other issues I read this plst from slate:

"To make a long story short, I am having (what I think are) power issues with my screen. The problem seems to get much worse in colder weather (0-17C). The LEDs on the 'button' board will light up, so I know it is getting power, but the screen itself does not turn on. I have checked all connections, and I know they are good. The only way to fix it is to unplug the power connector and plug it back in repeatedly. Sometimes it works after one power 'cycle' and sometimes it still won't turn on after many cycles (this usually occurs if it's especially cold out). This has happened so many times I can't even count.
"
And a review for this monitor on mp3car store.com has similar issues:
"The input/output box has some major flaws. The monitor output thumb screw connections do not even match the thumb screws on the cable (one is coarse thread and the other is fine thread) making it difficult to get a solid connection. The motherboard input connection has spring loaded "clamps to secure the cable to the connector. It is super loose with no way to tighten it down. Both of these situations are not good for vehicle operation. I've already had to return the I/O box for repair after less than 15 hours of use.
"
I like the idea of the separate input box, but man this looks like its been causing alot of people trouble. If anyone were to ask me I would have to advise them to stay away from this monitor at this point...
