This is a main control module problem since you can't bring up the menu. I recommend contacting your local svc co.

Lcd tv screen goes black after a few seconds but sound still plays. The flashlight test will show the image for a short period of time but then it goes away and is completely black.


Hello... It sounds like you have a backlight failure, and the image going away during the flashlight test is due to the TV going into "Protection" mode. A service technician may be able to go into the service menu and clear the lamp error codes and get the TV working, or it may need the backlights replaced. I hope this helps...

LC-37SH12U picture is upside down


Its somewhat common for this to happen and generally its an easy fix but since your set doesn't have the flip picture option your going to need to get into the service mode to fix this...below are the steps on how to get into the service menu on a Sharp TV...once your in there you need to look for either mirror image or H invert, and change that setting from on to off or off to on depending on what setting you have.

* While the LCD is on, unplug the power cable.
* Then while pressing the {INPUT} & {VOL -} buttons on the remote, plug the power cable back into the outlet.
* When it powers up you will see a little "k" appear in brackets.
* Then on the TV, press and hold {VOL -} & {CH -} down and release.
* The Service Menu will be displayed.
* Use {CH+} {CH -} buttons to navigate
* Use {VOL+} {VOL -} buttons to adjust the value.
* Turn the set off to exit the Service Menu.

Sharp Aquos Lc-65d90u verticle lines and srambled images in one section of screen. Is this the LCD panel and is it worth fixing?


Hello; If there is at least one vertical line that does NOT go FULLY from top to bottom, your LCD panel is cracked. This panel will cost much more than what you paid for the set. WII controllers are responsible for the death of many TV's.

You then tell them that you want to get set up for service. They will have one of their authorized professionals come and fix your tv in a matter of days.

Got a sharp pn-455. Powers up, but no display, no


Do you have a remote? If not, while it powered up press input button on the front of PN455. What do you see?

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 .

No Picture


I doubt that your component has burned out. You may be looking at a repair issue here even though your unit is only 3 years old IF: you have tried connecting using different inputs, OR if you cannot bring up your sharp menu, or you list of inputs. If you cannot do those following things, you have a SERVICE issue on your hands and unless you purchased and extended warranty with sharp, its useless calling them. They will just tell you tough luck, and refer you to one of their authorized service centers. good luck
