So I finally got all my parts wired and mounted and I have run into two major issues.
1st Issue, with everything wired up, when I connect the power, the power indicator (on the powerboost) does not turn on, only the charging indicator. (so the system is not powered).
I went to the power strip and desoldered wires individually to find the source. I found that if GROUND is connected for either the Amplifier or the USB Hub (either both or separately) it causes the issue. Doesnt matter if 5v is connected. Any ideas what could be causing this? Easy solutions?
The wiring is USB HUB ---> USB Soundcard ---> Amplifier
If I disconnect them, the Pi gets power.
The second issue is just that the screen doesn't turn on, but that could be from like 100 different things.

Re: Troubleshooting (GBZ wont turn on)
Try adding one item at a time to the power strip, so pi first, then screen then whatever, the chances are something is shorting out but you can slowly add more knowing what is working and what your issues is.
With regards to the turning on again this week probably be a short, I had a similar problem recently when I pushed doyen on my wires on the powerboost it would start, I took all wires off powerboost /switch /USB charging port and resoldered and all worked after that.

Re: Troubleshooting (GBZ wont turn on)
Agree with Lpoolm.
Backtrack a little. Go:
Powerboost --> Powerstrip
Powerstrip --> Pi
Powerstrip --> Screen
Then test.
Probably a short ot bad wiring on the audio devices.
As for screen output, ensure your composite is wired correctly and that there's an imaged SD card in the pi. If there's no SD, no boot
