Very often on HDTVs there may be more than one YPbPr connection... That is the Red Green and Blue. Under each one, or next to, or above, there should be separate red and white audio hookups for each set of YPbPr hookups.
Make sure they are hooked into the corresponding plugs.
Hope that helps.

The red white and yellow cables are composite connections. The red/green/blue connections are component connections.
The playstation's composite connections consist of two audio connections- red & white, and a composite yellow video connection. The TV's white connection is the audio, and the red/green/blue are component video. You need an adapter that will connect the one yellow(composite video) to the three red/green/blue (component video) connections

I called westinghouse with a similar problem(my picture shows up but all the white turns blue or somtimes pink).
they say the problem is similar to that of the xbox 360's red ring of death problem. Now what needs to be done is the unit needs to be unplugged completely for about 30 minutes. this allows the unit to completely cool down. and when the unit restarts and heats up the troubled connections will reflow and all will be fixed.
I tried this and it worked well for my TV. but it is only a temp fix and will need to be done again if the problem occurs.

Just do a hard reset to this set and check. To make it a hard reset, unplug the TV from AC mains wall socket, and re-plug it back after 15 minutes or so. If this do not help you, the main board to your TV is faulty. Contact any service technician. If you wish to get some details; check the site linked here. Viewing it in "Mosaic" will make surf easy.
