The remote for my samsung ht-tx72 doesn't work even though the tv and dvd reciever lights on the remote work. It doesn't turn on my home theater system. Do I need to reprogram it?

Sounds like to optical pickup (laser) has gone bad. Unfortunately on this model Samsung never made just the pickup available for replacement, they always made you replace the entire changer. The last few times I've tried to find this part for replacement I haven't been able to locate one.

You need to cable from your TV audio out to aux in on the HT-TX72. here's a link to the manual.
You'll find what you need on pgs 23- 24. good luck.

Look in the manual...

The TV >>receives<< Video and Audio from the Samsung. Page 19.

The unidentified TV with its unknown audio capabilites has a manual somewhere, too.

How many TV's are actual audio sources?

If the TV is actually a root source of programming (say, through its own antenna) you can run cables from it to the Samsung as you would any other audio source. If the audio really comes fro ma Cable Box THAT is where the best TV-related audio will come from.

HDMI audio is going where in your scenario? By default, the audio is assumed to be handled by the HT, not some external device. Does your TV have better speakers?

the batt are stil ok enough Voltage?
your IR led is not interupted?
dipswitch are adjusted?

I have no audio. I hooked it up to another TV and same issue.

You can try this one it worked on my home threater system

• Power On with empty tray (No Disc will be displayed in the DVD control panel)
• Press the Enter button on your remote control
• Press the buttons 8, 4, 2, 6, 9 and Enter button on your remote control
• Tray will Open automatically
• Close the tray on the DVD player
• After 15 seconds have elapsed, power Off your player (switch the unit to stand-by mode) and then power On your player
• Finished and ready to play all regions

hope this helps

Hi,
You need to put away the remote for your TV and use only the remote for your HT system. Your HT remote should work on your TV by default. Your Samsung HT remote should have a TV button and a DVD/Receiver button (or HT button). When using only the TV, press the TV button and then use it for just the TV and when using the HT system, press the DVD/Receiver button and then you can use the HT system.
If for some reason your TV is not set on the Samsung HT remote by default, your HT users manual should have a list of codes that you can use to program your HT remote. Hope that helps you. Gary

Try updating your firmware... samsung.com Or have you tried that?
