Thank you for using Just Answer.
Try this -
On many older TVs you are able to access the inputs by using the "Channel Down" button and going below channel 2.
I'm sorry. I wasn't aware you had tried that already.
Do you have the owner's manual for this TV?
I can try to locate one if you do not have it. That should give exact information on how to change the inputs.
Also, is the model number (that you posted above) the exact model number that appears on the sticker on the back of the TV?
Thank you for your patience.
I'm going to "opt out" of this question.
This will flag the question for other experts who may have the information that you need.
Please do not ask the question again.
If you do, you will need to repeat the work that we already done because it will not link to the above.
We'll see if someone else has the answer. Maybe you're right. There is no answer.
The question will remain open if you would like. Someone else who see this and knows the answer will answer in the next 24 hours or so.
It may be worth checking your email later or tommorow.
You are not charged anything until you decide that your question is answered and you click the accept button.
