Hardware Hacking Falied SX Lite install No display output

[malicks250]

Hi All,

After installing the modchip into the console, I had the green light but nothing on the screen.
Then I decided to completely removed the chip from the console and now the Switch is fully turning on expect I don't have any output on the screen .
The backlight is working, can hear sound while touching the touch screen and buttons are working also.

I think I have of a short which affect the display output due to my pre-tin on both side the chip cable near the Nand area.

It will be very nice if someone can help me fixing this Switch.

Many thanks in advance for the help

Saw this video before when trying to find hwfly lite installation videos:

You can see when two ribbon connectors are unplugged switch should boot to ofw. IIRC if you mess up any point (ABC or D) your switch won't boot at all, but you said you can still boot into ofw and have sounds, so I'd suggest to check display ribbon connector, maybe it's not plugged all the way in or you knocked off some component near the socket.

Maybe try to swap the motherboard to the other working switch and see if screen works?
By the way is the screen pitch black, or is just the backlight off? You can put a flashlight on the screen and if screen's on you'll see a dark image. Also check backlight circuit, you should get about 17V iirc.

the backlight is working fine, only nothing displaying on the screen.
I did swap motherboard and the screen is fine.
