I have a LC-C3242U 32-inch Sharp Aquos that does not power on. No even the green indictator light turns on when I press the power button. Any ideas!

Unplug it for about an hour to let it reset first.
More likely the standby 5vdc power supply is dead right now, that will be the fist place to look.

Why won't my LC-C3242U Sharp Aquos tv won't turn on

Fault with the main power supply regulator board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts.

It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time.

If power light continuously flashing it means backlight problem. Two possible causes. One, backlight invertor is faulty. Two, but realy rare, one of the CCFL lamps went bad.

Sharp Aquos LC-C3242U power issues

Do you get any indicator lights at all, if you do, then the 5v standby circuit is working, if you get nothing at all, then the main power supply will be the first palce to look, blown fuse? capacitors?

Green light is on but screen is black

It's either the backlight lamp or backlight inverter is busted due to a power failure or fluctuation. Here's how to determine which is which:
  1. Grab a flashlight.
  2. Turn on the TV.
  3. Shine the flashlight onto the screen.
  4. If you cannot see any display even a faint one, the backlight inverter is dead, else the backlight lamps are busted.
  5. Replace which ever is the culprit.

Sharp Aquos 32 wont turn on

I called up Sharp, and if you are a part of Sharp AQUOS Advantage Program you get free in home service.

They were very nice about it, and I already have a technician coming to my house on Saturday and I called on Wednesday.

I doubt Sharp's policy alot less now!
