greetings!!!

i am repairing a 14" AOC monitor, model: 5en, black chassis. Its first
symptoms was a ticking sound with no other action. I found a shorted
MOSFET transistor (IRF634B) in the secondary side of the low voltage
PSU. Tested other components in the PSU but they are ok. After
replacing the transistor, it now turns on but the display becomes too
big and it comes on and off accompanied by a clicking sound. I observed
that its the high voltage that comes on and off. Then after that cycle,
there's no raster anymore. But the frontpanel light is on and the
control for screen adjustments responds when pressed. Can anyone give
me suggestions on how to fix the problem? thanks in advance.

regards,
