Hwfly : green light but no image

[linkref]

Hello,


When installing a hwfly lite I clumsily ripped off this (black circle) : https://ibb.co/CV9tj5Z
So I stopped everything and tried to boot the switch: I had sound and the touchscreen responded as well as the keys but I had no images.

I decide to continue installing the HWFLY, installation went well --> purple led for a few moments and then green led.
But still the same problem no image.

Do you have any ideas? do you think it's my stupidity that caused this problem or nothing to do?

Look like you rip off the pad.

 

[jkyoho]

repair the ripped pad with professional and should be good to go.

What's the procedure to repair a pad ?

Bring your wallet and find a microsoldering professional tech

If nothing is on the pad, just bridge it with a wire.

I hate guys like you i'm just trying to practice

Sadly no. If that pad does nothing. You can do a jump wire basically. I don't know if it's something being used on it. @jkyoho knows the hardware a lot more than I do.

Try your best jumper the red line from bottom to top. Don't cry or hate yourself if you mess up more.
There is nothing on the path along these 5 pairs of LCD dataline from APU to LCD connector.
Use 0.1mm wire as short as possible to minimize the inductance from the jumper wire.

Thanks a lot, i will try and let you know

Couldn't he also jump directly from the port to the bottom pad?

 

[jkyoho]

Yes and No, it would work from bottom pad directly jump to the LCD connector pin but inductance will change. There is reason behind why those dataline doesn't go straight wire but hairpin loops by engineer.

 

[Hassal]

You can try those trace pens to connect the line. Its an easy and sloppy way to do it but quite effective.

Those lines had to length matched for some reason @jkyoho is right about that. If possible try to use as small wire as possible.
