RCA L46WD22 Television - Answered Questions & Fixed issues

Its a surge capacitor, the set will work without it but I would recomend relacing it, I'm guessing it looked something like this.

What is your signal source, OTA or cable? Did lightning or another type of power surge recently hit? Make sure you have the TV on the desired input.

If OTA check your antenna direction and that you have the Channel Setup (from the menu) set to Antenna. Also check if you have the right antenna to get stations in your area. Antennaweb.org gives the most likely channels and directions. tvfool.com will give more detailed information and more stations. Both sites assume outdoor antennas but the direction information is always good. Look for new construction or big trees that might block the signal. Do you have multiple TVs sharing the same antenna? You might need an amplifier.

If cable, check the Channel setup. Check for someone recently damaging your cable installation (cutting the wires, trying to split the signal to get it for free) Splitting the signal to multiple TVs may also be an issue, get an amplifier of the correct type. Some cable systems may require a bidirectional amplifier.

If you recently had a power surge, see if the TV works with other inputs.
Tuners can be replaced if the TV is worth the labor costs for you.

I hope this helps.

( My household had three tvs and a digital to analog converter that lost their tuners after a nearby lightning strike. We chose to replace the TVs since two were over 15 years old and the third was also out of warranty.)

I hope you have made the connections right. If the connection to video input ( yellow connector) is right, then the cable it self may be defective. Please try interchanging video cable with one of the two audio cables.

These blinks (Flashes) are fault indication, and known as blinking codes. From the number of blinks occur at one time switch ON; you can get an idea about the faulty circuit stage inside the TV. This will make repair easy. For more information, check these link s http://electronicshelponline.blogspot.com/ http://electro-medical.blogspot.com/

Contact the authorized service center for RCA.

as of june 2009 there are no longer any anolog channels only digital

Replace C540,C541,C542,C543 1000uf 35V and C544 680uf 35V in power supply

If the screen unit or display panel is damaged or cracked it is the end of the set--part alone costs more than a new set----if some other issue describe it.......

If its flickering on and off( loss of picture) it could be solder related to the inverter. If the pic stays and the set just flickers lines in the pic then I would think its the LVDs cable to the tcon or the connecters from the Tcon to the LCD panel.

I own the L46WD22 for a few months and lost the sound and analog inputs, only HDMI worked, apparently this is a design flaw and they should have recalled all units. I didn't really needed the speakers because I have a sony receiver where I playback the sounds, but I decided to repair it myself after I neglected to take it out to the repair center and use the warranty. If you have a little soldering experience you can fix it, or you can buy the fuse and take it to any repair center, the problem is a surface mounted fuse that is located in the PCBA where all the signal inputs are, the component location is 1C33 the fuse has the letter F printed on it, you can't miss it, it's about 2 inches behind the tuner where you plug the coaxial cable. the fuse I bought it's marked with a G letter, it's 750mA, I just soldered it on top of the one it has, now I can hear the speaker and use the analog inputs (and now I'm the hero and have a very happy wife). the whole fix took me about two hours

make sure that you have it set to the right input signal source and that your source is working properly. if so then yeah, you need to replace the fuzle modulator.
