It may be detecting short circuits in the power supply or in the backlight inverter board, try disconnecting the power cable to the backlight inverter board to see it you can get it to come on without the pictures.

Problem With the Sharp TV LC-32SB23U 32in LCD TV Serial No# 810825838


Those blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices.

If blinks continue without any pause, the main board is faulty.
Search the site by type in the "brand name" to your device, in the "Search box at the top right of the display window of the Homepage" to get gathered related posts.

Power light blinking no display on lc 32sb24u


Its almost always caused by bad capacitors on the power board. You can get a repair kit or the replacement power supply board from www.tvrepairworld.com

Green light blinking


Unplug it for about an hour first to let it reset, if it is still bad, then you will have to open it up or take it to the repair shop. The power supply will have to be looked at first to make sure all the voltages are present and no damaged components.

Power light blinking green,nopicture lc-32sb24u lc-37sb24u


This same thing happened to me, but not until I fiddled with all of my remotes, trying to see if it was an input issue, battery issue, etc. I finally unplugged the tv from the wall and plugged it back in. Nothing. Then I went to take 5 minute ****. When I finished, the Power & OPC lights were blinking, and out of sync. I pressed the power button at the top of my TV and got a picture.
