Hardware No Display but Dock works

[Crossfader]

Hi at all.

I have a Switch with no displaying anything. The Switch boots up and the Touchscreen works fine, you can her the unlocking by clicking.
In the Dock the Switch works normal. I got the Switch as water damage, so i clean it with IPA, there was very tiny bits of corrosion.
During cleaning the Display Connector i bent 3 Pins with the Brush, it was not fixable. I replaced the Connector 3 Times, but i cant get any on the Screen.

I mean i tested the Display itself with an other Mainboard.

Is there some thing that i can test or measure?

hi,
I have the same problem with a Switch buy on eBay. works well on the dock but no image on LCD despite the replacement of the connector.

I haven't found the source of the problem yet.

Did you test the filters below the connector?

They are available on AliExpress, search for Switch LCD FPC Connector. You ca also watch if some pins are bend inside the connector, I had this once and was able to push the pin back to its place with a needle

The Connector is new from Ali and no Pins bent.
The Chokes have continuity.

Did you ever figure this out? I'm fighting one now

Check p13usb chip for video output, it is normal to see shorts when there is water damage.

No, i will check the connector pins in Diode Mode.

i know this is simple but could it be the backlight? shine a torch on the screen and see if there's an image
