You have problem with the psu.Three capacitors 820mF/25V are dead and there is a fuse 3A worn out
Hi,
I have same no display but blinking blue power button light prob.I opened the 740n and seen these three 820mf/25v capacitors and they are definatly blown as I can clearly see that the top of all of em is not straight which is symptom of blown capacitor.I am not sure about the fuse All I see is one fuse just behind 220v power pin connector,a round brown fuse.
All I am confused is that what caused all this as if I even change the capacitors it might again blow the capacitors as there might be some other part malfunctioning.
Can anyone put some light on it as if there are any other solutions. saadsatti@hotmail.com
Thanks
