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.

If your TV doesn't have an HDMI port on it then you'll not be able to use the player. Some players have hi def output jacks, but it isn't true HDMI so using a hi def cable would defeat the blu ray players resolution when viewing a blu ray disk.

A HDMI switch like this should do it.

I'm assuming that your new blu-ray player only has an HDMI port and your TV does not. In that case, does your tv have a component cable output? This should be five plug-in ports (red, white, red, green, blue). Amazon sells an HDMI to component adapter that you can buy here: http://www.amazon.com/eForCity-538581-HDMI-Cable-5-Feet/dp/B005QWH4QA/ref=sr_1_1?ie=UTF8&qid=1382102257&sr=8-1&keywords=hdmi+to+component+cable

Very likely the settings on the TV. It could also be the HDMI plug is not seated into the socket right.

Depending on if your surround system has a hdmi input or not. if it does you can connect the blu-ray player to it. If it doesn't have an hdmi input you will have to run the hdmi cable from the blu-ray to the tv then run a set of rca cables (red and white plugs) from the tv audio out to the surround systems' audio input jacks to get sound through the surround system. Most surround systems don't have an auxiliary input for another video device.

as far as hooking up your blu ray player to the sc-pt660, the only real way to utilize the surround sound (with true surround sound) is through the optical audio out. You need to connect your blu ray player through hdmi to your tv and then connect your blu ray player to your surround sound using the optical audio out/in. I, personally have the sc-pt660 hooked up through component cables so I don't waste an HDMI input on my TV. Except for cd's, there is no reason for you to use the actual dvd player part of the surround sound considering you have a blu ray player. In conclusion, hooking your blu ray player and the sc-pt660 up to get better video simply isnt possible (your blu ray player alone gives the best possible resolution, 1080p). As far as audio goes, run an optical audio cable from your blu ray player to your sc-pt660 to get true surround sound.
