20 Most Recent RCA 46 46LA45RQ LCD TV Questions & Answers


Side buttons stopped working. Original remote lost and cable remote will turn tv on and off but will no longer control volume.

Buy its original remote control, contact the authorized service centre, or authorized dealer to your device brand. They can either give you a genuine remote control to your device, or can direct you, from where can you purchase a suitable one. To select a proper universal remote control, you should know about the number of digits to its set-up codes. There are 3 digit, 4 digit, 5 digit, 2 digit and even single digit codes, to some brand devices. After confirming this, check the sites linked here. Both the sites have set-up code list and set-up procedure to many popular brand remote controls. Check which brand remote control has set-up code/s to your device brand, and buy that one according to availability. Brand name of the remote control isn't a matter, but it should have set-up codes in its code list, to the device brand you have. Please note: Every new universal remote control will have set-up code list, and set-up procedure along with its pack. Never accept a remote control, that hasn't both of this. For more details about the set-up codes, visit the sites. http://electro-medical.blogspot.com/ Universal remote controls are available at most of the electronic spare part selling shops. Visit some on-line sites too, which deals with electronic spare parts.

We have a 46la45rq RCA TV. The input button on the remote bring up the options but it continuously scrolls. The side buttons do not work either (no signal) Do you think it is the t-con board?

Check the remote control for its infrared emission. Check it with fresh batteries. Check it by pressing all the keys. You can detect the presence of infra-red emission from the remote control, using a cell-phone camera. If you wish to get more details about how to check a remote control, please visit this site. One among the posts has details about it. Surf the site with patience. In some cases, the remote control might need to clean. http://remotesearch.blogspot.com/ Search the site by type in this key phrase "how to test a remote control "in the "search box at the top right of the display window of the Homepage" to get the related post quickly. https://www.youtube.com/watch?v=jsSCNCW3IbQ [open and clean] https://www.youtube.com/watch?v=Qp-l1uh-5gE [open and clean]

RCA 46LA45RQ black screen on right side of picture, left side has picture and sound. Is this repairable?

Hi Dale There are 3 possible causes 1. A faulty tcon board,(can be purchased from shop jimmy) 2. circuit film connections between the tcon board and the pannel have become tarnished and require cleaning ,this can easily be done with a pencil erasor. 3rd and lastly you have a faulty pannel. I would try cleaning the contacts first,then if no success verify the tcon board to be good or bad and if still no go the answer to your question will be no,unless you want to dish out for a new pannel. All that said i have assumed you are at home delving into electrical items and are aware of all electrical safety practices to do with this passtime , please do not attempt to service any appliance if you are not sure leave it to an expert.

Rca 46la45rq has backlight and power but no sound or picture replaced main and inverter boards

Was this the original problem before replacing the main board? Maybe you have to set the new main board from maintenance menu. Sound and image comes from the main board, so i believe it has to be something about it... good luck

Why won't the cable channels scan

Your TV will not get digital channels if you do not program the digital stations to your TV. You can program the digital channels by running a digital channel scan. The entire process is completed from your remote control and does not require any tools. This task only takes a couple of minutes to complete, and then you will be able to enjoy digital channels on your TV

Televison station won't scan

If you are receiving a "No Signal" error message, verify that:
  1. All of the cables physically connected to the TV and the input device are secure.
  2. The input device is turned on.
Your TV needs to scan for channels before it can show programming from an antenna, from cable TV when the cable comes directly from the wall (no cable box), or from a cable or satellite box connected to the TV with a coaxial (RF) cable. Do not scan for channels if you have a cable or satellite box connected using AV (Composite), Component, or HDMI cables. The box selects the channel, not the tuner inside your television. If you are not using the "TV" input, press the INPUT button on your remote until the correct input mode is selected. To perform a channel scan using the coaxial input:
  1. Press the INPUT button on your remote to view your current input source. The TV (coaxial cable) input must be selected. This may appear as "TV," "ANT," or the channel and call letters of a station.
  2. If the TV input is not selected, press INPUT until the TV input mode is selected.
  3. Open the on-screen menu and select TV or Tuner option. (This varies by model.)
  4. Highlight Tuner Mode and select the correct option:
    • Antenna-over-the air signals from an antenna
    • Cable-direct from the wall cable TV, or a cable or satellite box connected to the TV with coaxial cable
  5. Select Auto Search or Auto Channel Scan. (This varies by model.)
  6. When the search reaches 100% complete, exit to the menu.
  7. Check the available channels:
    • Antenna or direct-from-wall cable-Press the Channel Up and Channel Down buttons on your VIZIO TV remote to view the available channels.
    • Cable or satellite box- Will return only one channel. Use the cable or satellite remote's Channel Up and Channel Down buttons.
If this does not resolve the issue, power cycle the TV and then re-run the channel scan:
  1. Turn off the TV.
  2. Unplug the TV from the electrical outlet.
  3. While the TV is unplugged from the wall, press and hold the Power button on the TV for 30 seconds.
  4. Release the power button.
  5. Plug the TV back into the electrical outlet.
  6. Turn on the TV.
Note: There is also an option to reset the TV to the factory default settings. This option is in either the SETUP or SYSTEM section of the on-screen menu. The option may be "Reset all settings", "System Reset," or "Reset & Admin." Consult your TV's user manual for the location and steps for resetting your model.
  1. Remove the coaxial cable from the DTV/TV connector on the back of your television and perform a channel scan to clear the existing channels. See the procedure above. This should not find any channels.
  2. Re-attach the coaxial cable to the DTV/TV connector and perform a new channel scan.
This video shows troubleshooting steps to use when a "No signal" message appears.

Why does the picture get red horizontal lines across it and then goes to red tint over the entire screen? I still see the picture but it is all red. It is only 2yrs old

All monitors/TV's have Red, Green & Blue Drivers. When they are all on the screen = white. For some reason your red drive is over powering the others. Most of the time, it's a transistor or a failing capacitor depending on age .

Next to do after gettig new power supply

The USB port is for viewing files that you have transferred to a flash drive ( stick, storage card with adapter etc.) Your problem with the TV picture is probably a bad backlight board ( the long board ). Buy the proper one (needs correct board #) from Shop Jimmy.
