Re: [NTLK] smoking Newt

If you open your Newt and you find a diode with a label D2 next to it on the
logic board close to the power plug and this diode looks somehow
burned/black/dark brown, it is time to exchange it.

I herewith quote a mail from Mr. PCBMan:

The part was originally made by General Instruments KNP76GI.

Vishay Semiconductor bought them. The part crosses to TPSMB10.

Look under TVS & ESD.

If you register you can get samples...
