Have TV Questions? Ask a TV Technician
Welcome. I am Mike, an experienced field technician. We are now connected together on this convenient website where I am able to help you. To get started, I need to know you can see this message and are able to reply to me here...
-If you absolutely cannot see the model number sticker on the tv, then you will need to send us some photos of the input jacks. Quality photos that we can see really good, not some dark blurry tiny photos... Can you do photos or model number??
** My replies can take up to 5 minutes to appear **** Do NOT start a new question **
looks like a serial number to me, which does not help, sorry need model number, not serial number.
Closest I could find 49LX770H.
See diagram on page 4 of this document:
Basically composite video like dvd with Yellow/Red/White goes to the jacks on the back of the tv:
Yellow = "VIDEO/Y" jack
Red = "AUDIO R" jack
White = "AUDIO L/MONO" jack
Use INPUT button to choose correct input.
Let me know how else I can help. If you can't find the jacks that are clearly shown on the diagram, take a photo and attach it here.
Before you go please take a moment to submit at least a 3 star rating at the top of this page. Then if you still need help you can reply back and I will be happy to assist you further.
