To reset your Onn Soundbar model 100069413, you can try the following steps:

1. Using the remote control:

• Press and hold the "Volume Down" button and the "Source" button on the remote control simultaneously for about 5 seconds.
• The soundbar should turn off and back on, indicating that it has been reset to its default settings.

1. Without using the remote control:

• Unplug the power cord from the soundbar and wait for about 30 seconds.
• While the power cord is unplugged, press and hold the "Power" button on the soundbar for about 5 seconds.
• Reconnect the power cord to the soundbar and turn it on.

If these steps do not work, you may need to refer to the user manual or contact the manufacturer for further assistance.

Echo Dots can also be connected to your soundbar through an AUX (3.5mm) cable. This is because Dots are equipped with an AUX output port, and most soundbars have an AUX input. This is an easy, wired connection that is possible with a soundbar, as long as your soundbar and Dot are near one another (or you have a long AUX cable).
Here’s how to make your wired connection through an AUX cable:
Get a 3.5mm AUX cord. Make sure it is a good length
Open up your Amazon Alexa app on your smartphone
Select ‘Devices’ from the Main Menu Settings
Select your Dot by its name
Select ‘AUX Audio’, then ‘Line In or Line Out’
Connect your AUX cord to your Echo and your soundbar
Now you are connected through your AUX (3.5mm) cord, and any streaming or listening on your Echo Dot will come through your soundbar as long as both are powered on. If you ever want to listen to your Echo Dot through another device, simply disconnect the AUX cable from your soundbar.

The Sharp HT-SB140 Sound Bar's internal PSU provides a DC output voltage of 19 volts. So you would need an external power supply that can provide a regulated DC voltage of 19V with the same or higher current rating as the original power supply.
When replacing the internal power supply with an external one, it is essential to ensure that the polarity of the output connector matches the polarity of the soundbar's internal PSU. The PW390-070 EF25 MF 1945 part number indicates that the power supply has a center-positive barrel connector. Therefore, you need to make sure that the replacement external PSU also has a center-positive connector.
It is also essential to make sure that the external power supply you choose can provide the same or higher power rating as the original internal PSU to ensure proper operation of the soundbar.

Can you access all of the ports on the ProScan PLDED4016A? There are some ports that face down (near the power cord) and others on the right hand side (as you face the back). The picture from the manual, https://www.manualslib.com/manual/1049754/Proscan-Plded4016a.html?page=8#manual , indicates a headphone jack and a coax audio output and analog RCA audio out. The headphone jack is at the bottom of the side input area below the component video and service port. The digital Coaxial and RCA Audio outputs are closest to the power cord.

The PC Audio port is an input when the TV is used as a monitor with a VGA connection to a computer. See https://www.manualslib.com/manual/1049754/Proscan-Plded4016a.html?page=12#manual for using the TV with headphones.

If the headphone jack doesn't work, you need some sort of converter or adapter. To use the TV's digital coaxial audio port with the optical digital audio port on the sound bar, you need something like this: https://www.monoprice.com/product?p_id=2947 . Note: make sure to get the correct input and output option; these are not bidirectional. You will need to supply the RCA digital audio cable.

For the analog RCA audio output on the TV, you have multiple options. A simple RCA (M/M) to 3.5 mm (M) cable will work. So will various RCA audio/3.5 mm adapters, depending on where you want to put the adapter. (RCA (M/M) to 3.5 mm (F) is the simplest since you have the Aux cable.) These will connect to the Aux in on the soundbar.

You can also use an analog to digital audio converter, https://www.amazon.com/Musou-Digital-Optical-Toslink-Converter/dp/B01HGHNCMW . You'll need to supply the standard analog RCA audio cable for most of these. Then connect the converter output to the optical audio port on the HTL1520B.

I hope this helps.

(Years ago, the 3.5 mm to RCA cable was often in the accessories for connecting a portable CD player to a stereo system.)

If you don't want to spend a fortune getting one from the manufacturer get an ALL IN ONE at Walmart (just an example) and program from the manual with the remote package.

Does the power light come on? If not, check the power cord and power outlet on the wall. Maybe plug in a table lamp to the wall power outlet to make sure the outlet is working. If the power light is on, check the Mute button on your JBL remote control. Also check the Mute button on your TV if sound and picture go through the TV first.
We had a Harman Kardon soundbar (model SB30) made by the same company as your JBL. It worked great for a few months. Then there were a couple of funny high-pitched sounds that stopped when we turned the soundbar off and back on. Then a day or two later we truned on the soundbar and it was completely dead - no sound at all. Harmon/JBL replaced the soundbar under warranty with a refurbished one which lasted about two weeks and dies the same as the first one. Finally, they replaced the second one with a higher model (the SB35) which is still working, although it occasionally makes a rapid clicking noise for a moment here & there.
