Question about RCA 46 46LA45RQ LCD TV

2 Answers

My RCA 46la45rq tv remote AND side buttons stopped working

The buttons on the side of my tv have stopped working completely. I can't use them to turn it on, change volume or channels. My remote will only turn the TV on, all other buttons are non-functional. Since no other buttons are working, I can't check to see if my kids accidentally set the parental lock. I've left it unplugged for 30 minutes, then 18 hours without any successful reset --when I turn it back on, it's just as I left it. Any suggestions?

SOURCE: rca tv schematics

This is an edited re-post of an earlier (recent) solution I offered:

High probability that a (too) cheap component called a capacitor, has lost capacitance and gained losses internally.

This leads to random problems with the start-up and finally with the continuing operation of the main power supply.

Since this is a common problem in 'switched-mode' power supplies, you should be able to 'score' a replacement supply from an RCA service center for somewhere between $75-$150 dollars US and since these supplies are often made by companies other than the branded name on the set, they are most often plugged into the boards they service and can be replaced without a soldering iron or no skills other than common sense.

I'd recommend unplugging the set, removing the back panel, looking for a smaller board with larger than average components on it, the latter consisting of cylindrical parts mounted both vertically and horizontally on the board (capacitors) and block-like parts wound with copper wire with black cores (transformers & chokes).

Also found on this board will be one or more larger aluminum 'heat sinks' that dissipate heat from semiconductors mounted on them.

This board should be visibly related to the incoming AC line.

If you are concerned about pulling plugs, either mark them (your own system) or take photos of them from several angles for reference before removing any plugs.

The part that often cause this kind of problem (capacitor) normally fails internally and may not show any signs of being sick such as bulging or chemical discharge and may not be detectable without the use of a capacitance meter and is mostly in the range of 4.7-100uFd/50VDC.

The reason waiting for the supply to start up is that when this part fails, it also becomes very sensitive to temperature changes so may be pulled back toward a value of capacitance that allows the supply to start up.

If you are curious, you can try placing a fan toward the rear vents of the set or alternately, using a hair dryer to blow heat into them.

One of these will cause the supply to start working again; heat or cooling will cause the cap to shift its value enough (depending on where it is electronically) to either further delay or speed up the operation.

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.

I have a RCA LCD TV and the power button and volume bottons don't work on the tv. Which board do I need to replace? Model number is 46LA45RQ

If these functions can be done by using its remote control, and only the front panel buttons are inactive, microswtches at the front panel board should be replaced. If functions are not available with a remote control too, the main board is faulty. If you wish to get some details; check the site linked here. Pull up older posts. Surf the site with patience.

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

RCA Truflat TV 27F522T is completely locked both manually and remote do not work. Was working manually but after checking menu for block accidently FPA locked not can't turn on tv at all.

You must have its remote control to unlock this TV. Try to make your remote control get repaired, and check these.
Most RCA sets use a four digit code to control the v-chip. The code reset is different depending on the model. Try each number until you find the one that works for you.

1. Hold down the MENU button on the remote and VOLUME DOWN button on the TV it's self at the same time for at least 4 seconds. The set won't say so, but the lock will be unlocked

2. Hold down the 0 (zero) button on the remote and the VOLUME DOWN button on the TV itself at the same time for at least 4 seconds. The set won't say so, but the lock will be unlocked

3. Hold down the MENU button on the front of the TV and the TV button on the remote at the same time for at least 4 seconds. 4- Hold down GO BACK button on the remote and MENU button on the front of the TV at the same time for at least 4 seconds.
Hold down EJECT button on the front of the TV set and the MENU button on the remote at the same time for at least 4 seconds. Depending on the model, one of the methods should unlock the V-chip. Now, if desired, you can change the settings on the V-chip by going to the MENU and going to PARENTAL CONTROLS, or on some sets, going to MENU and then going to TV SETUP, then to V-CHIP SET.
