Hi ,
Here are steps that may help you fixing the problem. You should
prepare tools and multimeter.
I'm assuming that your unit is dead set without an standby LED
light and your outlet is live.1.Power cord - check the cord it might be opened (no
continuity).This is due to frequent bending,pulling. 2. Power switch - check for dry joints, open contact. 3.Check the internal fuse-
sometimes the fuse fail because of the power
surge, replacing with new one will cure the problem, If this is the case
I've advice you to use surge protector/AVR (Automatic Voltage Regulator).
However if the fuse blew again this is an indication that you have a shorted parts on the power supply, you may visit the
linkhttp://www.fixya.com/support/r8053361-fuse_keeps_blowing for more info. If no reaction and
still the unit didn't power up then you have an open parts on the power supply.
4.If you see that the fuse is intact on the board, don't attempt to touch
anything because there somefatal components
stored electricity enough to hurt you with a simple mistake only.
The next steps should be done by an expert or qualified technician
because isolating the problem on the power supply is technical and complicated.
Also check if your unit is under warranty before opening the back
panel, it will void the warranty. Avail it because the manufacturer of your
unit will fix it for free or a little charge only.
Hope it may help you.
Thanks for using fixya.
