Probable power supply failure. The power indicator only shows that house power is getting to the TV.

SOURCE: RCA universal nor cable remote will program RCA L40FHD41 TV

might be able to use the cable co remote and autosearch thru the codes, but its too hard to explain, the cable tech should have ran that procedure. unfortunately, rca has 50 million models. it is common to have a tv and yes rca for sure, to not take the codes. sometimes the tv is too new for the cable company remotes to work. i am leaning toward the tv too new theory. give it six months and i bet there will be a new remote version.

If you have tried 5 remotes I would have to say that the set has a problem in the remote circuit. You will need a tech to look at it and repair it. Let me know how this works out for you.'

SOURCE: my rca l46wd22 tv has major problems, my volume

This model has issues with a small micro fuse that will blow for no particular reason. Poor design most likely. This fuse is a solder on type and is very tricky. Have a shop check it for you before you trash it. Should not be an expensive repair. Thanks for using fixya.

SOURCE: RCA L46WD22 LCD tv (3 year-old unit)...No picture,

The back lights inverter is working because you can see the "Unusable Signal' on the screen, if the inverter is dead, yoo will see nothing on the screen at all.
If the T-CON (LCD controller) is dead, you will see just gray glowing screen with no pictures or text.
You may have problem with video processor in the main logic board (tuner, audio, source selector).
Parts for your TV:
http://www.shopjimmy.com/catalogsearch/result/index/?q=RCA+L46WD22+&stock=all&limit=100

This is going to be difficult repair since you do have a way to try out the replacement board to be sure that is the problem. RCA service person has that advantage of parts in stock to try out.
I estimate the board from Jimmy to be about $150, from RCA will be twice as much, plus labor.

Please see my basic troubleshooting guide here:

My RCA 42LA45RQ Will turn off by the remote , turning back on is intermittant. I can unplug the power cord, wait a minute, and the remote might work. The button on the panel does not work at all.


Main system control memory IC fault. This is a very small IC; have 8 solder terminals, and can be located very near to the main system control-chroma IC. Check and replace it. Be sure to replace it with the same number printed on it; in all respect. Otherwise, it won't go. http://electronicshelponline.blogspot.com/ Before replacing it, try a reset to this set, and then check.
There are two methods to reset TVs. The first is simple to do; a Hard Reset. The other is somewhat skilled; is a Factory Reset (System Reset). To make it a hard reset, just unplug the TV from AC mains wall socket, and re-plug it back after 15 minutes or so. If you do this by overnight is better. This procedure will make it a hard reset. If you want to make it a system reset [Factory Reset]; you have to enter its service mode option, and select the factory reset option. If you wish to get some details; check the site linked here.

My RCA LCD 42" TV control buttons on the television wont work, and the only button that will work on the remote is the power on/off button.


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.

Stopped working completely


No, your fuse has blown due to an electrical problem. Ill get right to it. Very possibly the capacitor and HV diode need replacement.90% of the time this occurs. If by chance it still doesn't heat or still blows fuses, replace the magnetron. Before you do all this, look carefully at the transformer and look for any indication of burning, or flashing having taken place. If so, replace the transformer first.(Transformer doesnt often go faulty).

Bose 3-2-1 Remote Control stopped working


I purchased a LAZBOY universal remote (at Fred Meyers, on sale for $9.99) and after a bunch of research and trial-&-error, was able
program it with a code (1629) which works reasonably well with the
Bose 3-2-1.

I don't have all the system-level functions (which I never utilized anyway) but do have all the basics as far as power, volume, source, and CD/DVD control.

Input button on my new universal remote doesnt work


You'll have to try a new code for your TV.

http://66.77.167.109/rcaaccessories/RcaaccessoriesController.do?ACTION_TYPE_ID=ACTION_TYPE_CATEGORY&ACTION_CATEGORY_ID=STR_CATEGORY_UNIVERSAL_REMOTES

Click the remote code finder link on the left towards the bottom of the page.

Select your remote and device (TV in this case) from the dropdowns.

Scroll down the results page to your brand of TV and try all the codes until you find the one that works with all the functions you want.

Best of luck!

Need code # for rca tv


If your remote control has a search button, this is how you do it-------- User submitted information for the SystemLink 3: To clear things up and make it simple, here is how to program the RCA Systemlink 3 remote:
****WITH DEVICE TURNED ON****
  1. Press and hold the "Code Search" button until the LED lights, then release. LED will stay light.
  2. Press and release the device key to be programmed. LED will go off when button is pressed and back on when released. LED remains on.
  3. Press and release the remote On/Off (power) button as many times as required to turn your device OFF.
  4. When device turns OFF, press and release the ENTER button.
Test remote on device, if ALL functions do not work, repeat above procedure.
***IMPORTANT NOTE*** Count how many times you press the On/Off button. If ALL funtions do not work and you need to repeat, you don't want to stop at the same non-working code. For instance, if it takes 23 times to turn your device off and after testing, the remote does not control all functions, repeat steps 1-3 BUT when the device turns off at the 23rd time, turn it back on using the power button ON THE ACTUAL DEVICE then continue with step 3 and 4 from above.

Hopefully you have the problem solved.

If not, the RCA plugs, listed as input 1 and 2 are shown on channel 91 and 92.

I recommend connecting the DVD to either input. Turn on the DVD. Then run the auto programming function of the TV. It will find and program the channel for the DVD. Then use the channel up or down on the remote you are currently using and you should find a working DVD.

Hope this helps.
