Usb port how do you use it
Hi,
By service port they mean a device hookup that a tech can use to diagnose problems with your TV. There is no practical use for you to plug into it. If you want to display your laptop on the TV you need yo hookup the video out from your laptop to the TV's PC/RGB input.
Hope this helps FixYa,
Chris

Programming Notes
• If your device does not respond to the remote after trying all codes listed or your brand is not listed in the code list, use the Auto Code Search method to program your remote.
• Sometimes the first code that "works" with your device may operate only a few functions of your device. There may be another code in the code list that performs more functions. Try other codes from the code list for more functionality.
This is a trial and error procedure; and quiet time consuming. You might have to check different codes said for your device.

In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.
Before going further; try a hard reset first. If it does not help you, replace the main digital board. There are two methods to reset TVs. The first is simple to do; a Hard Reset. The other is somewhat skilled; is a Factory Reset (System Reset). To make it a hard reset, just unplug the TV from AC mains wall socket, and re-plug it back after 15 minutes or so. If you do this by overnight is better. This procedure will make it a hard reset. If you want to make it a system reset [Factory Reset]; you have to enter its service mode option, and select the factory reset option. If you wish to get some details; visit the site linked here.

Not receiving cable signal
If the video from your DVD player is good, it suggests that your problem is not the video board! Have you swapped the cable coming in with a "known" good one? Also, have you got your source selection set for DVD player still, and not CATV? That's all I can suggest with the info. available. Hope this helps!
How do I replace the IR sensor?
If you took the batteries out of your remotes to change them, they possibly lost their programming and need to be reprogrammed. I drop my controller often and have to reprogram it. All of the lights light up but the TV appears dead. Either find your control programming guide or look it up on the internet how to reprogram your remote.
