Sounds like everything works. Your remote has an input menu. Have you cycled it around to the right component? i.e. HDMI1 or HDMI2, or DVD, even PC?
If not, try that.

If your Sony Blu-Ray player and LG TV are recent models, each should have an HDMI cable connection. HDMI is an method to connect your digital video and audio devices with just a single combined cable. In the case of your LG TV, using an HDMI cable will allow you to send the HD video signal to your TV's screen, and allow you to hear the sound through the TV's speakers.
Your LG TV may have multiple HDMI connectors, to allow other devices to send signals to your TV, such as a cable box or satellite box or digital video recorder (DVR). Your Sony Blu-Ray player will usually have just a single HDMI connector.
Purchase an HDMI cable from your local electronics store. There are different versions of the HDMI specification, and you should get a cable that you can verify is certified for the HDMI version 1.4 specification.
Plug one end of the HDMI cable into the Blu-Ray player, and the other end into one of the HDMI connectors on the TV, noting which one you selected.
When you turn on your Sony Blu-Ray and your LG TV, you should use the remote for the LG TV to select the input source. Your LG remote should allow you to select the HDMI input connector you used, at which point you should see the display of a DVD playing on the Blu-Ray player. If you cannot hear the sound, use the LG remote to increase the TV volume.

Wow it seems as though you've pretty much done all of the applicable troubleshooting for this issue. The only other thing I can advise in this case is to consider purchasing a SD card. Some Blu Ray players require a little extra memory to function properly so they come with an SD card slot. Of course no one tells you this when you buy the player but it may be the solution to your problem.

I have the sane problem! Help me!

first run a yellow cable to tv (AV) if does work it maybe a setting in blu-ray or TV look for any settings in the TV and blu-ray menu that says HDMI communications or something like that and turn it off. try to connect HDMI cable again.

Your TV only has a DVI input, not an HDMI which PS3 has as an output. You can buy a HDMI to DVI adapter and connect the HDMI out of the PS3 to the DVI input of the TV. To get the true HighDef video you need a HDMI input on the TV to enjoy the full capacity of the Blu ray capabilities of the PS3. DVI came out before the HDMI standard and your picture will look good but not like HDMI. I have the same problem with my samsung 65 inch. I Bought the wrong technology. I hope this helps and good luck!

try a new HDMI cable.

I have the PS3 and this TV and it works....Try this.

1. Turn ON TV
2. Connect HDMI from TV to PS3
3. Select the correct HDMI input on the TV for the PS3(important)
4.Turn OFF PS3 if it is ON.
5. hold [I/O] Power button on PS3
6. Wait about 5 second and you should get the "HDMI Detected" or some similar message.
7. Configure the HDMI output for the PS3

Also, If you set the PS3 to "auto" for hdmi, it may set the resolution to 1080i. You may want to deselect everthing but the 1080P.

Either the new BlueRay player is defective, the HDMI port on the player is defective, or the port on your set is defective.

Try connecting it with component RGB/AV cables, or S-Video/AV cables and see if everything works. If so, then you know that it is either the port on the BlueRay, or the port on the TV set.

To test the HDMI port on your TV, you will need another HDMI device to try.

Is Yamaha HTR-640 a receiver? Try HDMI from PS3 to receiver or Sony HDTV. If HDMI from PS3 to receiver the you need and HDMI from receiver to out Sony HDTV. You could connect everything to receiver and HDMI out to HDTV. You can not have an HDMI cable AND an optical cable coming out of the PS3, only one or the other.
