Hello all. So i have this samsung for a few weeks ive been trying to work through the faults. I have made a little progress but ive stalled with it now.
So when i first opened it up i found the main fuse blown and a couple of wires links next to the main cap melted under the glue. It had also melted the leg on cm810. After more checks i found 2 shorted mosfets and also the bridge rectifier was shorted.
I replaced all them components. The fuse no longer blows and i have 5.22v standby. I have the standby light if i turn the set on i get five flashes from the front then it just turns solid red again. Also if i try to turn the set on again the red led does not respond unless i disconnect the mains for about 10 seconds and then plug back in.
One thing i have noticed is i always seem to have 385v on the main cap from the instant i plug in the mains power? Im thinking the must still be more damage from the shorts but could do with some guidence in tracking them down. Thanks in advance.
