20 Most Recent RCA L46WD22 Television Questions & Answers


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.)

This sounds like a very common issue.

If set is hard to turn on (takes several tries)but will eventually turn on hereis what my guess would be.

Every set has a standby power supplythat is running 7/24 if the set is plugged in and it supplies voltage to theremote circuit that turn on the main power supply for the tv and hence turn theset on.

This is an area where companies cut corners by using lower rated voltage caps.By this I mean Standby usually provides under 10 volts to trigger the seton----what they do is use filter caps rated at say 10 volts max in a circuitwith 9 volts (example)=with the standby on all the time the filter caps(electrolytic caps) dry out and fail.

The problem usually begins where you have to turn set on or or two times andgradually gets worse--takes longer and more tries to get it to come up.

Once on it will stay on until turned off for a period of time.

The caps will begin to work better (regain some of thecapacitance) as they get hot--hence one it is on it will seem ok.

The beauty of this problem is most of themhappen when set is a year or two old (no warranty) and all you have to do islook at the top to locate bad ones.

They are generally black or blue and round and vary in --they have twoconnections each--a + for positive and a - for negative--not unlike a batterywhich in a way they are. The + and - are marked on top and bottom of most boards.

They are easy to replace and not expensive parts.

The tops are silverand metal looking with creases on top and if bad they will be puffed up ontop---tops must be perfectly flat with no brown material leaking top or bottom.

If this is your problem once you id them (make a drawing) you can begin.

Here is the critical part---on each cap is also marked the value like 220uf 10vdc---220 micro farad at 10 volts maximum.

If you find for example 6 puffed up and all are 10 vdc replace them with thesame value capacitance (like the 220 uf) but go up to at least in this case(from 10 volts) to a 16 or higher rated voltage cap.

The only issue is when you go up in voltage rated value the cap is larger sosometimes there is an issue of physical space for the replacement on the boardto fit them in.

The reason they cheapen these sets in this way is if 10 caps and you make25,000 sets there is a considerable savings in parts cost.

They do not care as long as it lasts past the usual one year parts warranty.

I have taken the time to be long winded because this really sounds like it maybe the problem you have.

See attached photo of a typical cap and if you have questions or need advicelet me know.4_2_2012_4_02_42_pm.jpg

Hi I have the same problem with this firmware, could you fix it?. thanks mail: [email protected]

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

You should adjust the resolution by the lap top, to adjust the full screen view on TV. Not with TV. Refer the user manual to your system, to know more how to do this. If you wish to get some details; check the site linked here. Viewing it in "Mosaic" or "Magazine" will make surf easy. Pull up older posts. Surf the site with patience. Do a search by type in the brand name of your device at its search box and press "Enter".

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.

  1. This is a very common problem with these models.
    The problem is very likely is a fuse that has blown, if the following is true:
    No Video on any input BUT HDMI and
    No Audio at all.
    Purchase a fuse, these are freaking tiny from digitalkey.com or mouser.com F1455ct-nd
    Pull the back off of your unit
    Pull the cover off of the PCB housing. It is the box that contains the hook ups including the cable tuner.
    The silver box that you screw the cable to is where you begin to look for this fuse.
    About two inches behind this silver box is some numbers printed on the board 7c32 and partially obscured will be 1c33
    Using a big magnifier look next to the numbers listed above, you should see a tiny rectangle fuse with an F on it.
    This F fuse is a 500ma fuse that is too small for the load
    The fuse listed above will have a G on it. It is a 750ma fuse.
    Call the repair shops in your area, tell them that you know the problem, have the part and you want to know how much the bench time and labor will be to repair your unit.

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
