Question about Sharp Aquos LC-45GD6U 45 in. LCD HDTV

1 Answer

Suddenly, my LC-45GD6U picture went black and now there is no picture but the blue power light is still on. I cannot change channels, change the input, change volume, etc. Basically the TV does not work with the remote or the buttons on the top of the machine. I have unplugged the unit and plugged it back in - still have the same problems. In fact, I cannot even turn off the TV!

Look like a classic case of Main SSB failure. Do you have sound? If not then it is confirmed that the microprocessor on the SSB has failed. YOu are gonna have to replace the board to fix it. Let me know if you want to do it yourself

    It is easy. You will find the board under a metal plate at the center of the set. Remove it and get me the part number off it and I will find you a replacement. Replacement is very simple. You should just unplug the connectors from the older board, re-plug them on the new one and screw it to the chassis. Cost if you replace about 150$. If the tech replaces it 400-500$

Screen went black while watching, now ony have sound

Look at the venting grills, you should see whit lights inside the set. If not, the backlight inverter board may have gone out or the power supply supplying the power to the inverter board may have gone out. Those are the two places to look first. It may have bad capacitors in the power supply.

Red power light continuously blinking. no picture no sound.

It could be the lamp went out and needs replacement. The Toshiba website states when this happens to unplug the televison for 10 minutes then plug back in. If that does not work then try another power outlet. If that does not work then call for service

Plasma Hyundai 42'' TV ,NO SOUND OR PICTURE

most times then not it's the capacitors on your power board that blew there for not supplying the tv with enough power if you open it up and check the capacitors it should be leaking some kind of liquid or the tops have bubbled up. its an easy fix cost>>2 dollars each

Try resetting the TV. Here's how to do it - Unplug the TV's power cable. Keep the Channel Down and Volume Up buttons on the TV pressed and plug the power cable back into the outlet. You will hear a click when you plug it back in if the reset is successful. Hopefully this should restore your video and audio.
