Hi Ruben, if you do not have short in the main filter the demagnetizing coil ptc is the main suspect, work with a serial lamp instead of fuse
Successes
I leave the image of the ptc, take it out and see if the TV is running, if the image is stained do not be scared, it is that the ptc is missing

Hi Ruben, I thought you had solved, I tell you, the fuse can jump for a short in the main filter (if this is the case we will study it)
if there is no short in the main filter, the suspect is the ptc, the ptc of the philips know how to get in touch and they burn the fuse mysteriously, I leave you an image in the answer
