as for the the coils and post here the result .

Re: NEVIR NVR-7402-40HD-N no standy by light
I understand what you mean but this diode is not conect to the LNK6777E it , the anode goes straight to the transformer and the cathode goes to a resistence that is under the heatsheld and then goes to de 103m blue capacitor thats near the main capacitorLast edited by mi16rs; 02-03-2022, 01:18 PM.Leave a comment:
