Can I connect my Oontz Angle 3 speaker to my AOC Envision L22H998 TV using a bluetooth transmitter?

I don't know if the OS on the UN55FH6003F will work with a USB bluetooth adapter; it would depend on if it can find the driver. A Bluetooth audio transmitter is more likely to work. This is one example: https://www.amazon.com/Bluetooth-Transmitter-Wireless-Headphone-Speaker/dp/B0838YPSZT/ref=sr_1_3?keywords=bluetooth+transmitter+optical+input&qid=1686438206&sr=8-3 . This model comes with various audio cables and a power supply.

I hope this helps.

Transmitter Battery
The estimated average battery life span of the transmitter is 2500 hours of use. If you suspect that the transmitter battery
has run out, contact your authorized Polar Service Center for a replacement transmitter. Polar recycles used transmitters;;;

start-search-enter bluetooth-and find your speaker.

Hope this helps.

to reset the entire unit do the following:

1. Press and hold "Menu" and "Channel +" on the TV.
2. Using other hand, press the power button.
3. A small screen should appear in the top left part of the screen.
4. Using the remote, select "Memory Recall" and select.
5. Power off and re-boot the computer 6. Run channel auto-scan to regain the picture.

Considering you have been patiently waiting for almost two weeks, you probably have found a cure by now. If you have, please post it as a comment to help others.
If I had seen this before, I would have suggested pulling the AC plug overnight to see if it would reset itself; all modern sets are very complex making them prone to unintended actions of the kind we live with on our crummy PCs.

Yellow Is VIDEO, Red & White is your AUDIO. (Stereo). They should go color to color on the TV's AV input. This is AV, and you use 3 wires to connect this way.
The Red, Green, & Blue, is called COMPONENT, & is ONLY VIDEO, the AUDIO, still must use Red & White. So to connect with Component you use 5 wires, altogether, 3 for Video, 2 for Audio.
Plug them in color to color & choose the right INPUT on the TV, and turn on your input device.

The AOC Envision A17W221 only has a NTSC tuner (analog). If you are using an OTA antenna, you probably need a digital (ATSC) to NTSC converter box to get any TV signals. These include the ones sold with the government coupon at the switchover. Very few analog stations still broadcast; they were limited to low power transmitters. Thus you need to be close to the transmitter to receive a watchable TV program. For the best signal to the AOC A17W221, connect the component video out on the converter box to the component in on the TV. The specifications for the A17W221 are available on the Amazon sale page, https://www.amazon.com/International-A17W221-17-Inch-HD-Ready-Panel/dp/B0009IRHL8/ref=cm_cr_arp_d_product_top?ie=UTF8 . This monitor is no longer available from Amazon but the site is still there. Newegg also has the specifications for this monitor.

Unfortunately, I can't find the manual for the A17W221. AOC only lists a few manuals for current models. These are available here: http://www.aocmonitorap.com/my/user_manual.php .

I hope this helps. To check for available stations in your area, use a site like antennaweb.org or tvfool.com. Antennaweb gives very conservative estimates on stations that you should be able to receive with an external antenna.
