It means "lets start" in Spanish, but you might want to change/check the LCD backlight & inverter first. ;-)
Good luck.

    If your able, test the voltages from the power board and see if they are correct, this is a LED set so there won't be an inverter board in it so that won't be the problem with the TV

Have you check all inputs as the HDMI inputs and the composit inputs are processed on a different bd?

SOURCE: no sound

When you turn the tv on, do you hear a faint “pop” noise from the speaker? If so, the problem is with the heat sink under the audio IC. Over time, the heat sink will lose its consistency and start to melt, thus shorting out the audio circuit. To fix, you’d need to clean off the melted residue on both sides of the audio IC as well as replacing the heat sink with a newly redesigned Sharp Heat Insulation Pad. It’s a pretty complicated fix, I suggest calling your local authorized sharp service center to fix this problem. The part is inexpensive, so you’re most likely looking at a labor charge (maybe around $200ish) for the repair if they are not marking up the price too much.

Sounds like a over heating issue, try unplugging the unit and leave it for an hour , before you reboot. make sure there is some kind of ventilation in place . Also double check your connections very important.

SOURCE: My Sharp TV will only hear sound. No picture or images even from the tv menu setup option. Model# LC-19SB25U. About 1.5 yrs old. Converter box ok.

In most cases, you can reset the TV by leaving it unplugged for 30mins.
If this doesn't work, I believe the circuit board that supplies power to the screen maybe bad. They call this board a backlight inverter board. It would most likely cost more to repair than replace the TV .

Model no. 32A33M LCD sharp tv, 32 inch, of serial no. 804734030. no picture shown. only sound is coming. i can decresing/increasing the volume. what can be the problem .


Do a flashlight test. With the TV on and a program is playing, shine a flashlight on the screen. Can you see movement in the picture? If yes then the backlight drivers are not working. If NOT, then the T-con board is bad You can get parts from here : TV Parts Universal TV Stands DLP Chips ShopJimmy

TV has sound but no picture


Shine a flashlight up against the screen. You you see any image at all? If so, replace the power board. You can buy it here, but act fast, it's eBay, and auctions don't last forever. I even managed to find a supplier with %100 positive feedback for you!

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.
