Question about RCA 20F420T 20" TV

3 Answers

Tv Volume is Locked

Our Hand-Me-Down Sharp Unytron television suddenly stopped letting us control the volume. It only lets us have three settings; no volume, half volume, and full volume. The problem is, the half-volume is still WAY to loud.
There was no remote, but we have been using a Radio Shack 5-in-One Remote just fine for over a year. The problem is the same whether we use the remote, or just click the TV itself.
We can't really afford a new TV right now, so any help would be greatly apricated.

    I tried unplugging it for an hour, and the problem still persists. Anymore ideas?

    also, there is no menu, as far as I can tell, or none that I can get to without the original remote.

Hi and welcome to FixYa,

Initially, pls post back the exact model number of the Sharp Unytron, something like 13RV629 or 20SB50.

Offhand, let's try the basics/easy ones. Try to see if you could enter the MENU/SETTINGS/AUDIO. The idea is to reset the audio controls back to default factory settings. Normally, there would be a choice for personal settings, try to reset that also. I suspect that there is nothing wrong with the Sharp, it was just programmed to operate like that by the previous user. If the universal remote does not have a MENU button, see if there is one at the front/side panel controls. Once inside the MENU, the channel up/down and the volume up/down would control the selections.

Good luck and Thank you for using FixYa.

Try first unplugging tv power plug for a while, so that you can reset the TV, then verify that your all in one is controlling the TV, eventually reinsert code.

If the problem is none of the above, then it is a faulty TV, to find out the TV must be tested with original remote.

Try unpluging the tv fot a hour and see if the settings reset. also look in the menu if you can find a settings reset or factory defaults to that direction.

One for all universal remote i am trying to program my seiki television. I lost the original remote and the power button on the television is broken so I cant turn the television on


Always better to buy a genuine replacement. The problem is that if I remember correctly, Seiki don't actually make the television, which is why it never features in the Remote Code Lists. I have just checked three sites.

None of the codes are working to set up my xfinity remote to adjust the volume. Is there a code that isn't listed?


No as the codes listed are for the settings in the remote if the code listed doesn't control the volume you need to get an updated newer remote with all the newer code sets
As you may find that one code controls the channel and another may control the volume and will be unable to use them at the same time
