Re: Phillips 520FL3603D/F7 Power Supply Dead
Hello..Sorry I completely missed your questions here !.
Ok the problem is that the TV has no power. Not even getting into the Standby mode when turned on from the power switch. It has no reaction from the Remote control, because the standby circuit is not working because the ZD905 got shorted out the 1ohms resistor got a bit hot and deformed / altered its value. I am not sure about the luck of IC901. There was a quote or reply to me that since ZD905 is now burned, IC901 is compromised. Therefore I did not deem necessary to plug it on mains and test.
Yes I understood that the criticality of R929 is a fuse. I believe though as a matter of good practise that these parts must be replaced before plugged onto mains.
2.1ohms it is the parts value as it is measured out of circuit.
No Nothing works cause for caution reasons I did not plug it on the Mains. The IC will be available 05/23 on Mouser.
So hence no voltages have been measured yet.
If you guys insist to plug it I will go for it. I just need to be extra cautious. I have no variac or isolator transformer in my lab yet. The mains voltage here is 240v.
Thank you very much R-J. ! Appreciate the effort from all in this group
