Just joining the chorus of thanks to Wifey_Sherriff for post #88 in this thread! This worked like a dream in our situation.
We just bought a brand new Sony Blu-Ray player (BDPS3100) and when hooking it up to our TV (Samsung LN-T4061F, circa 2007), found that it would just show the "Sony Blu-Ray" screen for a few seconds when turned on and then go to the standard "No signal found" screen when a device is off (even though it wasn't). Tried multiple HDMI ports, etc.
Somewhere on some thread on the Internet, I read the suggestion to try upgrading the firmware of the Samsung TV. FOR THE LOVE OF GOD, DO NOT DO THIS.
That's where all of our trouble began... :P In other threads, Samsung tech support reports telling people they should never
do this themselves, despite the fact that there are no warnings on their website, and they even have a frigging video telling you how to do it, etc.
ANYWAY... I digress.
After the firmware upgrade, all of the colours were completely screwy, like some psychedelic 60s acid trip... bright pinks and greens and yellows where dull neutral colours should've been. I found the solution at http://www.avsforum.com/t/1023759/trouble-after-upgrading-firmware-on-samsung-ln-t4061f#post_13743593
— entering the Service Menu and switching "Lvds Tx Fmt" from JEIDA to VESA. Worked like a champ!However,
on my way in to do that, I went and blundered into the same calibration setting as Wifey_Sherriff... I'm not sure what was on the screen at the point that I selected it, but the DVD player now had a blue-green hue that was impossible to get rid of.
That is, until I found this incredibly helpful thread!!
I downloaded the checker board graphic to a USB key, stuck that in the Blu-Ray player, went to the Photo section and displayed it there (waited until the menu bar disappeared) when re-selecting HDMI calibration. Hooray! Working again!
Incidentally, holding the "Stop" button of the Sony player in for 10 seconds after powering it on was what ended up solving my original
problem, and had this just been in the frigging Blu-Ray troubleshooting manual I could've saved myself 3 hours of stress. :P But it was a good learning experience, so there's that.
Thanks so much for this forum!
