Sharp AQUOS LC-26SH10U 26 inch LCD Television. Video input problems? No audio. I get a picture using RCA cables but nothing using coax cable. Also I have no audio. When I get a picture using the RCA cables I have some thin vertical lines on the screen. A Red line on the right portion of the screen and a few green and blue lines on the left portion of the screen. I would like to know which component board I would most likely have to replace? Thanks, Chet

Question edited for clarity and order, 'make model (what it is)'.

On the television remote you have to select the Source or Input. Each press will take you through the HDMI ports and all other signal inputs like co-ax. Your LA channel is likely via the co-ax indoor aerial.

There should be RCA type audio input connections near the ext-4 video cable. One red and one white. If you connect these cables you won't have to do anything in the menu.

Any of these will work.

ANTENNA IN: UHF/VHF 75 ohm Din type (If in HD Broadcast)
EXT 1: SCART (AV Input/Output, RGB Input, TV Output)
EXT 2: SCART (AV Input/Output, Y/C Input, AV Link)
EXT 3: S-VIDEO (Y/C Input), RCA pin (AV Input)
EXT 4: RCA pin (Vomponant Input)

When you are connecting this television to a signal source with a coax cable this happens. The solution is to connect with an RCA/composite cable instead and utilize the television's inputs instead of using input tv.

How are you connecting it to cable tv?

If you are using a coaxial cable to a cable box you have to turn to channel 3.0 with a Sharp remote by pressing 3.0 enter the dot (.) is down by the 0. There is a way around this if you don't have a Sharp remote. You can go into the menu and complete a channel scan. If the model you own is the one pictured then you should have the coax cable connected where it says analog if you are connecting to a cable box this way.

If you are using composite, component, or hdmi cables you press the input button on the television and pick the right input. It is recommended that you do not use the coax cable anyway unless you do not have a cable box. There is an input button on the television and on the remote.

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.

If you are using an HDMI cable the sound and audio will be in the same connector. If you are not then you must run an audio (stereo both L + R) cable from your satellite receiver to the audio input of your television.

If you are using a S-Video cable it only carries the picture and not sound.
In that case it also requires an audio cable as well as a video cable.

The best hook up for this unit is to use the hdmi if your samsung box offers hdmi output. The panasonic vcr should be hooked to any one of the composit video inputs with the yellow video cable and the red and white audio cables. If the vcr does not have composite output then use a rf (coax cable) to antenna a input and put the tv on channel 3 or 4 as vcr is set for.

No reason for the audio not to work on the RF cable. Check under menu and option and make sure audio is set to fixed and not variable.

The hdmi inputs on this unit go directly thru the main digital pcb. and the component inputs feed thru the av pcb then to the main pcb. If the composit hook up do not work and hdmi inputs do work the unit has a bad AV pcb.
