How do I install or replace the batteries in the remote control for the SHARP LC-20SH3U?
Before using your SHARP LC-20SH3U for the first time, or when the batteries are depleted, you need to install two “AA” size batteries (supplied) in the remote control.
1. Open the battery cover by detaching the cover while pressing the (▼) part.
2. Insert two “AA” size batteries. Make sure to place the batteries with their terminals corresponding to the (+) and (-) indications inside the battery compartment.
3. Close the battery cover by aligning the tab on the cover and placing it while pressing the tab to close it.
Precautions regarding batteries:
• Improper use can result in chemical leakage or explosion. Always follow the instructions.
• Ensure terminals match the (+) and (-) indications.
• Do not mix different types of batteries.
• Do not mix old and new batteries, as this can shorten the life of new batteries or cause old ones to leak.
• Remove depleted batteries promptly. If chemical leakage occurs, wipe it off with a cloth.
• If you don’t plan to use the remote control for an extended period, remove the batteries.
How do I use the remote control with my SHARP LC-20SH3U?
To use the remote control, point it towards the remote sensor window on the front of the SHARP LC-20SH3U. The effective range is approximately 17 feet (5m) within a 30-degree angle to the left and right of the sensor.
Cautions regarding use:
• Avoid applying shock to the remote control, exposing it to liquids, or placing it in high humidity areas.
• Do not place the remote control in direct sunlight, as the heat may cause deformation.
• The remote control may not work correctly if the TV’s remote sensor window is under direct sunlight or strong lighting. If this happens, change the lighting angle, move the main unit, or operate the remote closer to the sensor.
• Objects between the remote control and the sensor window may prevent proper operation.
How do I connect an antenna to the SHARP LC-20SH3U?
You can connect an outdoor antenna to the ANT. (Antenna terminal) on the rear of your SHARP LC-20SH3U. A good quality outdoor antenna is recommended for the best color reception.
Connecting a Combination VHF/UHF Antenna:
• If you have a 75-ohm coaxial cable (round cable with an F-type connector), connect it directly to the ANT. terminal.
• If you have a 300-ohm twin-lead cable (flat cable), you must use a 300/75-ohm adapter (not supplied) to connect it to the ANT. terminal.
Connecting Separate VHF and/or UHF Antennas:
• You will need a combiner (not supplied).
• Connect the 300-ohm twin-lead cables from both the VHF and UHF antennas to the combiner’s respective inputs.
• Connect the 75-ohm coaxial cable from the combiner’s output to the ANT. terminal on the TV.
Note: When connecting the RF cable to the LCD TV set, the F-type connector should be finger-tightened only. Using tools may cause damage to the TV’s internal circuit.
How do I connect my SHARP LC-20SH3U to a Cable TV (CATV) system?
The SHARP LC-20SH3U has a built-in 75-ohm coaxial cable connector for easy hookup.
1. Connect the 75-ohm coaxial cable from your CATV provider to the ANT. terminal on the rear of the TV.
2. If you subscribe to “premium pay channels” that are scrambled, you will need a converter/descrambler provided by your cable company. To connect this:
• A two-set signal splitter and an RF switch (both not supplied) are typically required.
• Connect the main cable line to the signal splitter.
• Connect one output from the splitter to input “A” of the RF switch.
• Connect the other output from the splitter to the input of the cable TV converter/descrambler.
• Connect the output of the converter/descrambler to input “B” of the RF switch.
• Connect the output of the RF switch to the ANT. terminal on your TV.
• With the RF switch in position “A”, you can view unscrambled channels using the TV’s channel keys. With the switch in position “B”, you can view scrambled channels using the converter’s channel keys (your TV should be set to channel 3 or 4).
How do I perform the initial EZ SETUP on my SHARP LC-20SH3U?

• Make sure the input mode is set to TV. If you are trying to view an external device, make sure the correct INPUT is selected.
• Make sure the POWER switch of the main unit is on.
• The TV may be picking up a signal from something other than a broadcasting station. Check your antenna connection and position.
Why is there no picture from the INPUT2 connection on my SHARP LC-20SH3U?
If you have no picture from a device connected to INPUT2, try these steps:
• Check the BRIGHTNESS setting in the PICTURE menu to ensure it’s not set too low.
• Ensure that the AUDIO ONLY feature is not set to ON.

• Make sure the antenna cable is properly and securely connected to the TV.
• Bad reception could be the problem. Try adjusting the direction of your antenna.
• If the picture is doubled or tripled, it may be due to reflected electric waves from mountains or buildings. Adjusting the antenna may help.
• If the picture is spotted or has stripes, there may be interference from cars, trains, high-voltage lines, or neon lights. Also, ensure the antenna cable and AC power cord are not close to each other.
• Interference from other devices like radio transmitters or cellular phones can also affect the picture. Try to move these devices further away from the TV.
Why is the picture on my SHARP LC-20SH3U too dark or improperly tinted?
If the picture is too dark:
• Press the BACKLIGHT button on the remote, or go into the PICTURE menu to adjust the BACKLIGHT or BRIGHTNESS settings.
• Check the CONTRAST and BRIGHTNESS adjustments in the PICTURE menu.
