Got a PS3 hooked upto a Samsung 40" LCD TV via

If your Playstation is putting out the signal in 1080p then try changing it to 1080i and see if that works. Not all TVs are compatible with 1080p.

Ur tv some how causes HDMI 1 and 2 port hubs link together so changes back and fourth 1 or 2 HDMI hubs will not a difference.Ur tv have 4 HDMI hub ports wright?Tries not to used HDMI hub ports as like HDMI ports like 1,2,3,4 to as in sequences.Tries used like 1 and 4,2 and 4,3 and 1 as skips sequences might work for ur tv.Tries to hook up the PS3 system as the old format hook up same hook as PS2 format like used the PS station old RCA AV cable hook up.Then that should not causes conflict at all because now tv have two difference kind of format hook up.

First, HDMI is not a perfect hook-up solution. Cable box connections via HDMI are notorious for being problematic. The best thing you can do is contact Samsung and get the latest firmware for your TV.
Samsung Customer Care: 1-800-Samsung (1-800-726-7864). If this does not resolve the issue, connect the cable box using Component cables instead of the HDMI. Component cables are HD also. I hope this was of some assistance.

for the ps3 i know why u are not gettin any video. make sure the ps3 is off with the red light showeing in the front then hold down the power button for (i think) 30 sec. u will see the light blink a bunch of times them you might have to re start it but it should show the vedeo againg

connect back to your old tv and reset the ps3 to default settings then connect to your new tv.

Re-Set the PS-3, by pressing and holding down the power button (front panel) this hard re-sets the unit and yo can then reconfigure via the composite video cable it came with, back to HDMI / DVI

Since you are running the to LCD monitor instead of a LCD TV this is where you run into the issue. because the monitor is not setup to pull out the audio from the HDMI connection. So there is a few ways that you maybe able to to this.

The first one is look around at the different output cables out there the PS3. (I just got one so I do not know the accessories that are out for the PS3) This is becoming a common setup so if Sony does not have cable that will split off the audio then a 3rd party group may. I know they have one like that for the XBOX 360.

Another you can try is if your monitor will except an analog connection you may need to go that way. That is how I have my XBOX 360 that is my room connected. I have a RBG HD to VGA connect the VGA input on the monitor and the audio going to my sound card.

The reason why I suggested going analog is that right with our curent technology that if you are run with the 2 formats at the same time you will get audio/video sync issues. So you need to go all analog or all digital.

I hope this helps. Let me know if you have any other questions on this and/or need me to clarify anything.

Is the 42 inch a lcd tv. is the blueray player & ps3 hooked up in the hdmi inputs?

ok your tv does not come with the very best sound, you have to get a receiver 7.1 or you can use the optical wire , that's if the system you are using has that option.

are you hooking up a 1080p source..if not then the set will not display the best picture in 1080p mode..
