So yeah. I was playing around with my TV, and the picture turned red. Yeah, like red red. It had a red tint, or a hue, or some such shit. So first I was obviously like, “ok some weird settings change occurred”. Check settings. Nothing. Reset settings. Nothing. Picture is still redish. I mean the picture is sharp as all hell, but on all inputs, the picture is red. Including the built in DVB-C tuner, the PS3, the Xbox 360 (both over HDMI).
The only thing that changed? I hooked up a desktop PC through VGA for testing purposes.
Yeah! Hooking up the PC over VGA borked the picture on all other inputs. Great.
Googling… Find a forum that has the solution, luckily. First page was all “I called service!!!”. Second page had the solution. Go to the service menu, set a setting back to normal and presto: we’re back. No service needed. So how was it done? Here goes:
- Shut down your tv, but leave it in standby.
- On your remote, pointing it at the TV, press, in order, Info, Menu and finally Mute. Do not hold the buttons down, just send one command per button to the tv.
- Turn TV on. You should now be in a Service Menu. (this should work for most Samsungs)
- From the ADC/WB menu, select ADC Result
- From there, find the 2nd_R_Offset value, which for me was about 20 or so higher than the 2nd_G_Offset and 2nd_B_Offset values.
- You should see the change immediately.
- To get out of the menu, shut down the TV and start it normally.
Note: My TV was running on the latest firmware available for this model. The PC was a standard Fujitsu-Siemens desktop, and i was running memtest, so nothing even remotely graphically complex. I am also running another PC over HDMI: My MediaPC. It runs XBMC on Ubuntu 10.04. No issues on this for the past two years I’ve had it.
I am therefore inclined to blame the VGA. This is an old model so a firmware fix is unlikely. I am also inclined to thank ‘vasili0s’ on the cnet forums. Thanks!
