Question about Sharp Televison & Video

1 Answer

My aquos LC-30HV4U no longer responds to commands from the remote or the buttons on the monitor (except the main power button). Sound is OK (though not adjustable), picture seems slightly darker, and the AVC system appears to be OK. Is this a circuit board issue? If so, which board/part # needs to be replaced? I would like to replace the part myself.

This would be a circuit board issue indeed, its called the controller board and that has you buttons and your ir sensor on the front to boot. If that gets replaced you will have a fine working unit again.

questions? please ask

My Sharp tv remote will not turn on / off tv. It will turn on by the main power switch on tv but not by remote.


From page 8 of the manual:

The POWER indicator on the AQUOS television should light GREEN indicating you have power to the AQUOS television.

If the POWER indicator on the AQUOS television still does not light up, press TV POWER on the remote control to turn the power on.

IMPORTANT:
IF THE UNIT DOES NOT POWER ON - UNPLUG THE AQUOS TELEVISION FROM THE OUTLET AND REPEAT THE INSTALLATION STEPS.

IF YOU STILL ENCOUNTER NO POWER, PLEASE CONTACT US AT 1-800-BE-SHARP

Hi my sharp aquos lc-30hv4u keep's blowing the main ac fuse 3.15amp 250v. i looked at the main power board it looks good. is there something i can look for? thanks for any help.


On the power board look at the electrolytic capacitors . The top of them should be flat. If they are domed on top or have leaked out the bottom then they need to be replaced.

Hi, I bought an aquos lc-30hv4u and it has no rca jack etc, only two plug ins labled display input 1 and 2. I am guessing its just a pc monitor. How would I use it for cable tv video games etc


There are lots of inputs on the back behind the cover. Three inputs (1, 2, 3) have an S-video, composite video (A/V) and component video jacks. The cover will come off if you press the two top hook at the top of the cover. Then rotate the cover towards you. There are also a DVI-D port and 2 coax (antenna in) jack. The tuners included are for NTSC (analog OTA) and CATV (analog cable). The front of the PC (VGA) and a S-video or composite (A/V) video input (called Input 4).

Composite and component video jacks are all RCA jacks (as are the associated audio jacks for the input). Composite cables uses three RCA plugs on each end - yellow for video, red and white for Right and Left audio. Component video cables have three plugs on each end that just carry video (red, blue and green); the audio is wired separately with just 2 RCA red/white plugs. Match your colors from the device out to the TV input.

Changing inputs can be done with the remote or the input button on the top of the TV. The input button is to the left of the power and Main Power buttons.

Connecting your game system, cable system and all will depend on the units. For the best picture, use component video cables for mose set top box. Some cable boxes have a DVI port - use that if the box has that option. If they do not have component video out, then use composite or S-video cables.

The owner's manual is available from Sharp as a pdf: http://www.sharpusa.com/CustomerSupport/ProductDownloads.aspx?downloadtype=ownersmanual . Use the drop down menus as follows > LCD TV, Model not listed, LC-30HV4U then click Search. The picture of the inputs are on page 10.

I hope this helps.

The screen and the module both are showing red lights . The screen will not show a picture and I have tried to reset. Any options?


Press the VOL+ and Channel - button on the set and than the power button while holding the two buttons.
If the set starts then the fault is the error counter wich must be reset to 0. Max is 5 faults,if a sixth error is measured the set stops.

How can I active the subtitle and caption for tv programs


My Sharp TV manual says there should be a "CC" button near the upper right corner of your remote control. Keep pressing the button to go through the different options.
Not every TV program has closed caption, so it may not every time.

I hope I answered your question. Please rate me. :)

Power on problems


this worked for me before, but now the problem came back after being fixed for months! unplug the two connectors at the back of the tv, the ones that look like computer monitor cables. then go to top of tv and use manual controls, turn off main power, then turn on while holding input and vol down button, a small service menu will come up, use the channel up down button to go to test, then push input button, there should be a box with reset and some number in red. use the vol buttons to reset to 0, then power off.... reconnect the cables and then turn on the tv.
