Lite-On PA-6601-1 - seeking help to identify blown transistor Q307A
Hi,
trying to revive a dead power supply Lite-On 600W TESLAconverter PA-6601-1 manufactured in 2003 and originally used in a PowerMac G5.
Transistor Q307A underneath a heat shield was blown - it was labelled A2700 H403. How do I go about finding a replacement transistor?
Thanks & cheerio, Harry.... -

Re: A1706 no power, no liquid
Thanks @BlueMidnight - could have thought of that myself
It also means I bought the right part
Will report back as soon as I've had a chance to replace the cap.Leave a comment:

A1706 no power, no liquid
Hi,
looking at a friend's dead MacBook Pro (A1706). Input voltage 20.41V with a current of 21mA.
Upon visual inspection I noticed blown capacitor C6580 and verified that a short to ground exists.
I am assuming this is the same cap as the ones nearby labelled NEB CN7, which I've tracked down to Mouser part number [URL="http://www.mouser.com/ProductDetail/kemet/t521b336m016ate070/?qs=lYGu3FyN48cAMR6%252bFafBAQ%3d%3d&countrycode=US¤cycode=USD"]80-T521B336M016ATE70[/URL]
Can anyone with a A1706 board confirm that... -
