    Sounds like the power supply board. Can try unplugging TV from the outlet. Hitting power button on TV several times. Wait 30 seconds and plug it back in. Otherwise most likely a power supply issue.

Sharp lcd screens are very easly damaged especially the larger screens,this could be at fault even though it looks ok,try shinning a light on the screen and checking every inch,could be the internal screen that has damage hence why not powering up.
Failing that it sounds like an internal short.

SOURCE: cello l2232af power supply fault, when switching

I had this same problem with my 23" cello TV. It was a problem with the internal power supply - specifically the 12V output. It had fallen to 5V. I noticed that the three electrolytic capacitors (EC7 EC8 & EC9) had bulging tops as though they had been damaged. I replaced these and my TV is now working again although I don't know how long it will last. The three capacitors were 1000uf 16V types. I replaced them with 35V versions (which are physically bigger and a tight squeeze). Your TV repair shop should be able to replace these faulty components in under an hour.

SOURCE: Green led indicator light is off on my 62" toshiba

when you turn it off your light blinks because your internal fans are still spinning allowing the inside of the chassis to cool off, hence the reason you dont watch a DLP TV and then unplug it. DLP's are JUNK

SOURCE: Sharp LC37D44U Power LED was flashing green. TV

I had the same problem. all the service reset would only make the display come on for a few second with no "k" on the screen - only the channel would show up. I purchased a complete set of board for the lcd on ebay, and started swapping them one by one. The inverter boards were the culpret. Tele working 100% since that board swap.

TV will not stay on


These 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 stage 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, to many popular brand TVs and other devices. Viewing it in "Mosaic" will make surf easy.

Direct Code Entry
  1. Press and hold the SETUP button until the red indicator stays on, then release the SETUP button.
  2. Press and release the desired Mode button (TV, VCR, etc.). The red indicator blinks, then stays lit.
  3. Enter the 4 digit code from the code tables. Note: after a valid code entry, the red indicator turns off. For an invalid code, the red indicator flashes.
  4. With your device on, press CHANNEL UP. If the device responds, no further programming is required. Note: If some buttons do not operate your device, try one of the other codes for your brand.

    5. Press and release MUTE to install the code. The indicator light goes off.
    Most users will want to store VCR codes under the VCR button, Cable codes under CBL, etc. If you want to store a VCR code under CBL, etc., first follow the procedure for Direct Code Entry and press CBL in step 2 of Direct Code Entry, then enter ANY VCR code in step 3 of Direct Code Entry.

Sharp LCD can't turn on


Bummer, one month out of warranty. This is why I always recomend keeping expensive, high tech stuff under warranty.
First thing to do is buy and download the service manual from servicemanual.net and find out what the fail code of 1 blink means.
