VMU Backlight problem [MOD]

So, I followed a few tutorials on youtube and other pages and I "succesfully" made a backlight mod for the VMU, using DS/DSi backlight parts.
The backlight itself works great. But the problem is that I don't see a clear picture on the little LCD.
It seems completely blank but if I look closely, I see a very faint picture...
It's like the pixels are shadowing/ghosting?

I wired the leds in parallel, soldered a 150 ohm resistor to pin 1 and ground to pin 7.
So I think the fault is not there. I used the polarized layers in the correct order, but still, no clear picture.
I tried a different order of the layers, but it stays the same...

Spend hours and hours to figure it out, searching on the net to find what the problem might be, but no result.

Does anyone know what I am doing wrong?
I would provide pictures of the mod but I guess there is nothing much to see.

Thanks in advance!

Also, first post here! wow

 

The only way you'd know if you got the polarization right would be if you started with a known working display and tested it and got a good display. Obviously that didn't happen. Go back to step 1 and test at each step and you'll find your problem.

 

Thank you for the information, but I did do that already. Repeated every steps a few times, even used another backlight, resoldered other wires,... same result with everything. At the end I gave up. Spend to many hours/days on it. Closed it up and used the original back of the display that came with the VMU, and it's working in it's original state. So the display was working for sure.

Oh well, thank you for the reply!
