Question about RCA L46WD22 Television
My L46WD22 is not recognizing any signal such as the cable box, dvd player..it just say unusable signal
OK...1st of all I want to GREATLY tetraedronic, who wrote to replace the F fuse with the G fuse. I noticed our TV had the exact same thing go wrong. I searched for the item # F1455CT-ND and bought it from www.digikey.com for a whole $2.85 including shipping. It arrived in about 2-3 days. Hubby bought a fine SILVER SOLDER and a $20 solder gun @ HomeDepot. We placed a quilt on the kitchen table, turned the TV on it's face and took off the base & back and them the back panel on the metal casement. About 2 inches behine where the coax plugs in there is a TEENY TINY fuse with an F on it.....we placed the new G fuse right on top of it and with the use of a magnifying glass we barely touched both ends with the solder and reassembled all we'd disassembled. Hooked Coax and power back up and BADDA BOOM....we have sound and the analog channels back. For us, there was NO other option. NO ONE here in SE KS will touch this TV. Oh, and when I say this fuse is small.....well...be prepared....you may inhale it, it is SO dern small. I bet it would take 4 or more of them to cover the head of a match from a matchbook...NO LIE. E-mail me with any questions if ya need. firstname.lastname@example.org
Once again, THANKS A MILLLLLLLION for this fix idea!!

Thank you Jbs_fanci and whoever told you too! I bought two of the fuses ( one as backup) and carefully soldered one in place. A very fine soldering pencil with just a tad of solder tinned on it can be held over each end of the part and carefully transferred on to the fuse. Now the TV woks great, just like new. Yeah! I took pics of the whole procedure. Thanks again!!!

Did exactly what jbs_fanci did and the TV works great! The fuse is very small and is a little tricky to solder but this will fix your tv if your experiencing problems with sound and picking up analog channels. Just solder the G fuse on top of the old F fuse and put the tv back together. The G fuse is .81 cents at www.digikey.com. I bought 3 fuses just in case I messed one up or lost one.

What was the value of the fuse.

I was having the same problem. Apparently there are problems with the "digital board" RCA part #274704. Unfortunately the part has been on backorder for a while. Good luck finding one.

I also had the exact problem about 2 weeks ago on my L46WD22. Took it to the authorized repair shop and they told me they had others on their shelf for over a month. Since the board has been on back order for a while, my repair shop called and actually got to talk to an engineer at RCA. The problem seems to be a surface mount fuse that RCA said they also could not get. My repair center said that he found a fuse to fit the board, and though it was a higher rated fuse, installed it. TV works fine and it is back in my house, but the repair center is not getting paid for the work they did not fix it!!!
