My LD1 laser of ADI-TOF cann't work

Thanks so much for viewing my question!

My LD1 laser of ADI-TOF cann't be lighted. Because of scratching of the electrode, there are some leakage of copper which causing the short circuit. Can I just use some materials which is insulating coating on the board? Or I should sent to the manufacturers to repair, since it will be a long time and I am in a hurry to use it.

Thanks again!
