Can i use mini lcd displays from cell phones with external video signals? I'd like to use them in a sculpture project as windows in a building and send video signals, in proper resolution, to them. Looking for some help hacking theses.
IF yes, is there a format I need to use for video signals, can I convert the connections to simpler, less fragile ones, like RCA?

Thanks for your question. First i have to need to know had you reinstall your phone operation system? that means flash system. but you said you changed your lcd display. that means you hadn't no lcd fault. i think in your mobile motherboard capacitor or diod problems which block your lcd displaying system. please consult in your near any professional technician. thanks
this is from the LG website about that TV. - Rear, 2 x Composite video/audio input (RCA phono x 3) - Side, 2 x S-Video input (4 pin mini-DIN), 1 x USB (4 pin USB Type A), 1 x Audio line-out (RCA phono x 2), 2 x Component video input (RCA phono x 3), 2 x Audio line-in (RCA phono x 2), 1 x Digital audio output (optical) (TOSLINK), 1 x Digital audio output (coaxial) (RCA phono), 3 x HDMI input (19 pin HDMI Type A), 1 x RGB input (15 pin HD D-Sub (HD-15)), 1 x Audio line-in (Mini-phone stereo 3.5 mm), 1 x Serial (9 pin D-Sub), 1 x Remote control (Mini-phone 3.5 mm)
Do you mean the power switch does not shut it off, or do you mean it does not show the signal you want it to show?
I can't help you over it not turning off, but if you are not seeing the signal, it may be because the TV has various alternate inputs, and has to be switched between which one you want to show, such as:
2 x HDMI input ( 19 pin HDMI Type A ) - rear 1 x VGA input ( 15 pin HD
D-Sub (HD-15) ) - rear 2 x
S-Video input ( 4 pin mini-DIN ) - rear 1 x audio line-in ( mini-phone
stereo 3.5 mm ) - rear 5 x audio line-in ( RCA phono x 2 ) - rear 2
x component video input ( RCA phono x 3 ) - rear 2 x composite video
input ( RCA phono ) - rear
Try using the on screen menu to bring up a choice over which input to show. Switch it to the one you have connected to it.
This might be a sign of a faulty LCD cable or screen inverter board. The
LCD cable transfers data signal from the motherboard & video card
to the LCD screen. It also supplies high voltage DC power to the screen
inverter board. The screen inverter board works as a power supply for
the backlight lamp mounted inside the LCD screen. It converts low
voltage DC power to high voltage AC power needed for the backlight lamp.
Test with an external monitor attached to the laptop. If you get display on the external monitor, then this confirms the case.
here are the only signal inputs located at the back of the tv. 1 x HDMI input ( 19 pin HDMI Type A )
2 x component video input ( RCA phono x 3 )
1 x VGA input ( 15 pin HD D-Sub (HD-15) )
Audio line-in ( RCA phono x 2 )
2 x S-Video input ( 4 pin mini-DIN )
2 x composite video/audio input ( RCA phono x 3 )
1 x headphones ( mini-phone stereo 3.5 mm )
1 x SPDIF output ( TOS Link )
1 x audio line-out ( RCA phono x 2 )
1 x subwoofer output ( RCA phono )
1 x serial
If you are looking for a coaxial cable input.. it is actually not available so you have to connect a converter from coax cable to RCA cable for you to connect it on your tv.
Here is the list from the spec. sheet of all of the connections available on your TV
1.0 x HDMI ( RCA phono x 3 ) - Rear , 1.0 x Composite video/audio output ( RCA phono x 3 ) - Rear , 1.0 x VGA input ( RCA phono x 2 ) - Rear , 1.0 x Remote control ( 4 pin mini-DIN ) - Rear , 1.0 x S-Video input ( 19 pin HDMI Type A ) - Rear , 1.0 x Serial ( 4 pin mini-DIN ) - Rear , 1.0 x Composite video/audio input ( RCA phono x 3 ) - Rear , 2.0 x Composite video/audio input ( Mini-phone stereo 3.5 mm ) - Side , 1.0 x Audio line-in ( 15 pin HD D-Sub (HD-15) ) - Rear , 1.0 x S-Video input ( RCA phono x 3 ) - Side , 1.0 x Audio line-in ( TOSLINK ) - Rear , 2.0 x Digital audio output (optical) ( 9 pin D-Sub ) - Rear , 1.0 x HD component input - Rear
When you connect a data projector or external monitor to the external video port on the laptop, power up the data projector or external monitor first then the laptop. The video info will automatically divert to the data projector/external monitor automatically.
If you have already had powered up the laptop first, most laptops will allow you to toggle between the LCD screen and the external video port by pressing the Fn key plus one of the Function keys, this key will have a screen/laptop symbol.
You have to switch the CH1 and CH2 switches inside the lcd display to input 1 or input 2 to control the xlr inputs. If these switches are in int (L) and int(R) position, then you are adjusting the audio on the CH1 ad CH2 dials below the lcd viewer on the outside of the lcd for the on camera mic. Only use line setting on the front of the camera when you are receiving an audio feed at line level from an audio board. If you set the camera to mic setting, and you are receiving a line level audio signal, you will blow out the audio 0 way too loud, if you are receiving a mic signal and your switch is set to line, you will not be able to hear the mic with the audio Ch1 and ch2 all the way up.
Can not display what? Video? It should once in vtr mode. If it still does not work are you still getting signal to the LCD when recording? Does it Show on the LCD when connected to final cut? If you are getting any signal to it, it is a setting, prob mess with the video out settings, if not hardware.
If you want to display the info, try turning title on also turn character display off and on.
