G3 All-In-One 'Molar' Issue

[mattpnew]

Just hoping someone out there has had some experience with these, mine is just chirping between the power supply and analogue board... chirp..chirp chirp...chirp - LED is on, Fan is on, no chime and black screen. I've replaced the Logic board and Power Supply with known working versions but no luck. I've also pulled the battery and reset the logic board along with reseating everything. Any help is appreciated Cheers.

Flyback ??

Yeah those flybacks are all failing.... Hate to say it but they are...

That's actually good news as I found a new AB, so not a waste of $$$ thanks guys.

Does a faulty flyback explain the lack of a chime? And will it chime even with a faulty or no harddrive? I do know the logic board and power supply are ok.
