Lens alarm after replacing protective lens. falcon 2 22w

Creality Falcon
1

Hello

I was getting the lens error on my module and did the cleaning routine as per Creality support videos.

After this I was still getting the alarm and stop, so I decided to replace the lens completely with the one included with the whole laser package.

Unfortunately I am still getting the Lens alarm with a completely new and clean part.

Is there any other steps I can take to try and fix this before requesting warranty replacement?

I have taken a few more steps to rectify the problem.

I replaced the protective lens.

Updated the board firmware and the laser module firmware.

Checked all cable connections and their pins.

Still having the issue.
