How do i get my cable to work on my lg tv? what is the correct setting should be on my input screen?

It sounds like you are experiencing an issue with your Kortek MagicSing YK5000 not connecting to your LG Smart TV via HDMI. Here are a few suggestions for troubleshooting the issue:

1. Check the HDMI cable: Make sure that the HDMI cable is securely plugged into both the Kortek MagicSing YK5000 and the LG Smart TV. Also, check the cable for any damage, such as frayed wires or a broken plug.
2. Check the HDMI input: Make sure that the HDMI input on your LG Smart TV is selected and that the TV is set to the correct input source.
3. Check the TV settings: Make sure that the TV's settings are configured to accept an HDMI input from the Kortek MagicSing YK5000.
4. Check the YPbPr adaptor input: Make sure that the adaptor is securely plugged into both the Kortek MagicSing YK5000 and the LG Smart TV. Also, check that the adaptor is not malfunctioning.
5. Check the TV firmware: Check if there's any firmware updates available for your TV and make sure that it's up to date.
6. Contact the manufacturer: If none of the above solutions work, it may be necessary to contact the manufacturer of the Kortek

The horizontal lines that are showing up on your TV's screen is caused by either a bad cable or a cable that is not correctly fastened to the input and the output ports for the TV and it can cause interference then and the signal and cause horizontal or vertical lines to appear. It could also be the TV"s screen is no longer working and needs to be replaced.

Hummmm... the YELLOW RCA should be your VIDEO cable and have VIDEO signals.

Are you SURE your TV is set to the CORRECT "INPUT" SETTING? And DO YOU hear and audio>?

it's set to the wrong input device ? the one you currently have it pointed to has no input

also it's possible that cable plugged into current input channel has gone bad or become disconnected from it's source
Hdmi cables are unfortunately famous for this as they have no Lock device to keep them inserted into ports

most TV's nowdays shut off if not provided an input for a few minutes

Is it registering the correct input? HDMI/ AV1/ AV2/ SCART!

It should be set to where you have the input(ie...cable box, satelite, DVD etc) connected on the back or side of the TV

If you press play after welcome screen, you should see picture.

try to check the aspect ratio and input source to make sure they are correct. for the aspect ratio, make sure it is set either at 16:9 ratio or try the zoom options. if it is set at zoom, you can move the screen left to right or up or down through the zoom settings. make sure you are also using the correct cable. hope this helps

Unplug,replug the cable box and the tv about an hour.The tv will reset itself,back to factory setting.The cable box should reboot itself and upgrade it softwares.The tv should work again.

This is normally only caused by two things, 1st- if your using the RGB inputs make sure the green is securely connected or possibly a bad set of cables. 2nd- If your not using that set up then I would say you have a defective main board. Have it looked at by a servicer if you cant find anything wrong with RGB Comp input cables.
