I had this same problem on another RCA player.. with no instructions manual it was hard to figure out what keys locked meant. Then I noticed a little slider on the side of the player, it has a little icon of a pad lock on it. Once I slid this back, the keys lock problem went away and I was able to listen to my music once again.

My best guess of what keys locked means.. you don't want you mp3 player to turn on when you put it in your pocket with your keys, so you change the slider to be locked, when your sit down and your keys are pressing against your on button, the mp3 player will shut off... as we all have experienced in frustration.. saving your battery.

Perhaps RCA should make this slider bright orange so it pops out and does not blend in so much, or they should put it right next to the on button.

RCA Audio... | Answered on Sep 11, 2019

PCM mode is a digital audio file that should be sent to the soundbar via an optical or coaxial digital audio cable. The coaxial digital audio cable uses an RCA plug but not the L/R stereo channels of analog audio. The aux input is usually the 3.5 MM cable from a computer, CD or MP3 player or a cell phone or tablet.

First, which type of RCA cable is connected between the sound bar and the TV? Second, are you sure that the TV connection is an audio out? (A number of recent TVs have only one audio output. This means there is only the optical audio out and not even a headphone jack.)

Once you double-check the input at the sound bar, choose the Line In input if you are using the stereo RCA cable. If you are using the Optical input, select that input. Use either the Mode button or the specific input button on the remote. Then double-check that the TV is set for the appropriate audio out.

I hope this helps. Please add a comment with the model of the TV and the sound bar for further information. I looked at the ONB18SB001 documentation for some of this. The manual for this Onn soundbar is available at Manuals Lib. See https://www.manualslib.com/manual/1498038/Onn-Onb18sb001.html?page=12#manual for the list of input modes and the input to which they correspond. Here is the image of the inputs on the back of the ONB18SB001: https://www.manualslib.com/manual/1498038/Onn-Onb18sb001.html?page=7#manual .

Hi Yvonne, as you comment, there may be two reasons for failure, the internal RCA straps stretched and therefore fail to transmit the movement so that it works correctly and the other reason, the VHS tapes, which are wet
Observe through the two upper windows of the Video cassette, that the tape is without any white spots, if white spots appear, these are due to moisture and the tape with humidity, it cannot move correctly inside the video cassette, and can cause the fault what do you describe
Also verify that the drum of the video heads is clean and free of moisture
I hope you can watch your videos
Regards Franco Dosil

Hola Yvonne, por lo que comentas, puede haber dos motivos de falla, las correas internas del RCA estiradas y por lo tanto no logran trasmitir el movimiento para que fun cione correctamente y el otro motivo, las cintas VHS, que se encuentren humedas
Observa por las dos ventanas superiores del Video cassette, que la cinta se encuentre sin ninguna mancha blanca, si te aparecen manchas blancas, estas son por humedad y la cinta con humedad, no puede desplazarse correctamente dentro de la video cassettera, pudiendo producir la falla que describes
Verifica tambien que el tambor de los cabezales de video, se encuentre limpio y sin humedad
Espero puedas ver tus videos
Saludos Franco Dosil

Use code search to find something that works. If a search through all codes stored in your URC fails, try a different one.
