This is an indication of out-of-regulation in the power supply section. The very
common caused of this fault is the dried/leaky electrolytic
capacitor in that section. It
will drop the supply from normal voltage and
will disable the unit. Sometimes it has a bulged/dome at the top but not all, it is better
that you have a capacitor
checker/tester to determine
its condition. Also, bad
solder joints can produce the
same symptom, it is hard to spot, you should use table lamp/portable lamp for
finding the cold solder. Another reason of the symptoms is the open fuse/fusible resistor in series with the output of regulator IC/transistor, shorted/openRegulator IC/transistor,
shorted zener diode(all
are in the power supply section) and the microcontroller.
Best that you check the output voltage of each regulator to determine where the
fault came from and narrow the job.
If you don't have necessary tools
and test instruments, and can't do the job yourself, I would advice you to
look for a professional to troubleshoot the problem. Don't
attempt to work in the power supply if you don't know the safety precaution of handling it, there some stored
electricity enough to hurt you with a little mistake only.
Also check if your unit is under warranty /extended warranty,
avail it because the manufacturer of your unit will fix it for free. Don't open
the back panel, this will void the warranty.
Hope I helped you.
Have a nice day!
Thanks for using Fixya.
