Anyone Know The Value Of D1?

Skip to comments   Jump to end

So, I took a gamble and replaced the already good Regulators. The EZB still doesn't work. All of the voltages are there. D1 has opened up and doesn't show any transistor or resistive, or capacitive readings, just completely OPEN. I need to know the value so I can replace it as a last shot at this. I have believed it was the cpu from the beginning. They used to sell those in the store for $15 , I think. Now, I have found this diode open.

So, does anyone know the value? I am guessing 5v Zenier?

Nevermind, I found it. It is an SR-240 Scholttky Diode.

Thanks Anyway.

Except I think it needs someone else to have posted before he can close it as complete (unless it's changed since I last posted a question)... Free credit for Robot-Doc?:)

Thank You Both.

Got any ideas if I have voltages and everything looks good. The Regulators have been change and the bluetooth hooks up but no ports on cpu work.

Just a idea but have you tried heating up the solder on the other regulator just to make sure it has a good connection?

Yep! I change both regulators. They are putting out the right voltage. Regulated 7.2v coming in and 5v going out and also 3.3v after it is divided to that point. 5v on all middle leads and floating 1.5-2.1 on signal wires.

Try removing and then replacing the fuse between the two regulators. Then try re seating the MicroChip once more.

Thanks for the Freebie !
