Hi

I received my gearbest screen today and am wondering what the easiest way to test it is? I am hoping to test it first unmodded and then modded.

Thanks,
Cal

It's unlikely to run off 5v without adding a bridging wire from the +Vcc line to the third pin on the leftmost chip.

Hi

Thanks for the reply. I am aware of the mod to make it work on 5v but was wondering how to test it straight away (not on 5v) and then after with 5v. It comes with a rca cable that plugs into the board and has a white female, yellow female and red male plug?

I was thinking of plugging my Wiis scart cable into it but it's rca cable is all male.

To make 5V test, just cut the red RCA jack and solder and USB cable so you can plug it in a USB power supply.
then you can power with 5V and test with the yellow RCA on a camcorder or anything that can out on composite

Thanks for the reply. I was hoping to test that it's working before modding (and cutting red rca plug).

Any idea how I can easily do this? As I said, the cable provided has a female yellow plug, female white plug and male red plug.

you have to sacrifice the cable by cutting the male red plug to solder a usb cable

What I don't understand is the screen should be able to be used out of the box with the cable, right? I don't mean for the Gbz but with its natural 12v. I'm keen to test it is operational before modding it for the gbz.

There are male to male cables for this, which i have used to test my displays before touching them.
To make sure they were not DOA.

Hi

Thanks for the advice. Unfortunately I can't see how the male red plug from the screen could plug into that cable?

It seems strange the screen comes with a rca cable that has two female and one male plug, it doesn't make sense to me and makes me think there is something obvious I am missing as the screen is shipped out that way, ready to be plugged in an used.

Those are for Video only (the ones i have wrote about before).

The one you are talking about is the cable for power.
All screens i bought came with another cable for this. Female AV/Composite/RCA to bare wires.
This should be used to connect your red V+ to a power source of some sort.
