    More detail description of problem with Aquos LC37GU. Red Light comes when system plugged in, the light turns green and power up sound is heard when I hit the power button. After about 1-2 sec, there's shutoff sound and light blinks red.

    I would prefer to try resetting the TV before opening the case and changing capacitors, etc.

    Thanks for your help!

    More detailed description of problem on Aquos LC37GU. Red Light on TV comes on solid when system is plugged in. When power button is pressed, light turns green and audible power-up sound is heard. After 1-2 seconds, system powers down (audibly) and light blinks red. No picture ever comes up.

    I would rather reset TV before opening up the case and trying anything more drastic.

    Please help!
    Thanks

==================================================

1: TV can not be reset in Off or Nonfunctional condition. To reset it, it should be power On and then go to Menu to reset it.

2: In my opinion, your TV has defective back light inverter that needs to be replaced because this back light inverter board is causing power shut down as protection circuit activates to shut down.
Back light inverter board is available in Shop Jimmy.
Thanks.

Sharp aquos red flashing light tv won't get picture


if the tv is still under the manufactuer warranty i would definitly give them a call. If it is a Sharp tv I would call the 1-87-BESHARP. I would also try unplugging the tv for at least 2-3 minutes and seeing if the tv will reset itself. Usually what happens with these tv's when the light blinks it locks the tv as a security issue. If the unplug does not help it will more than likely need service to get this fixed for you. The call line hours are M-F 7am-7pm S-S 9-5 and they will be glad to help you from there.

Sharp LC37G4U Liquid Crystal Flat Screen


If this also happens on a DVD or video recorder, you could have a power supply issue or maybe a problem with the back light circuit. The best advice would be to take the TV back where you purchased it, if it is new. If it is not a new set, take the TV set to a repair shop for an estimate. Good Luck
