I keep on trying to set up my ps3 on the PCL541R tv and it just won't work. I've tried repeatedly and nothing seems to work. There is nothing wrong with my ps3 it works perfectly on other tv's but on the PCL541R t does not work.

Hey there! First, I'd like to ask a couple of questions:
How are you trying to connect it? Which input? Have you switched to the appropriate input on the tv? Did you have it connected to a different tv previously? Does it work on another tv?
If you're sure that it's connected properly and the tv is set to the right input, then I suggest a video reset on your ps3.

Make sure your ps3 is off and your tv is on. Press and hold the power on the ps3. It should beep once, then beep again. Feel free to release the button after the second beep, it signifies an audio/video reset. Try this and let us know if it works.

Good luck!

I have my ps3 on the same tv. its plugged into the front yellow white red jacks,turn the ps3 on, if your watching tv push the tv/video button on the remote,from there push the channel down button until you get to video3 then push volume+ and it should be on
