Thank you for using Just Answer.
Please post a bit more information so that we can answer this best.
Do you have the original remote control for this TV?
Do you have the original owners manual for this TV?
Can you see an input on the back (or side) side of the TV that is colored Yellow, Red and White?
Have you connected to that input with the cable that came with the DVD player?
Thank you for your patience.
On some TVs you are NOT able to access the inputs from the controls on the TV. On these you must use the original remote control (or a good substitute) to switch the TV to that input that you have connected to.
You can obtain a substitute remote that will allow you to switch the TV at the site below.
Although, a universal $10.00 remote may allow you to turn the TV on and off and change channels, it does not allow you switch the input.
Before you order the remote control, you can go thru you menus (the way you had the TV auto-tune itself) and see if you can find a area that is labeled "inputs" or "video source". If you find the "input" area, you should be able to switch it there. Start the DVD playing before you start switching so that you will see a picture when you get to the correct input.
Please let me know if you would like more information and/or clarification.
I found the Input and it worked.
Thank you for your help!!
