    need some help

    Hello I'm new here and I have a question I was hoping someone would be able to help me?
    I can't leave the main menu and I've tried using a mouse to navigate with no luck. Ive been able to find out that it is a chi mei innolux lcd serial number (m220z1-lo3) there's also some other numbers on here ( 89c1q0905ng0003 and cm22z13166tn4npa05m0035) display but I do not have the remote for it so I have no clue how to use this! Do I have to hook a computer tower up to this or can I just put USB stick in? is there a universal remote code? Any help would be amazing!!! Thank you if you need any other info please let me know

          I believe it is a monitor. It's basically just the lcd panels encased in a steel frame. There is a board on the side with a USB connector and a SD card slot.

                  That label seems to be just for the display panel, what is this thing connected to? What is connected to it right now that is puting the video of the gears on the screen?
                  There must be a main board, a power supply etc. also
                  Usually there are a few buttons that are connected to the main control board to control the on screen menu
                  Is there a touch screen that normaly goes over the display screen?

                      the panels on the bottom are touch sensors but touching them just takes me to a blank screen. there are 4 boards on this thing, 3 green and 1 white. there is a in line power supply. I've looked this thing up and down and it seems the only thing I can control is the volume knob on the top of the monitor. here are pictures of the 4 boards.

                          Hopefully it didn't have a touch screen cover over top because It didn't have it when I got it.

                              This merged company 2010 produces TFT LCD panels for a lot of big companies including tv manufacturers. Probably need to Google it and search.

                                  You are missing the keyboard that connects to CN7, You should be able to make one with a few buttons

                                      How would I go about making this? I don't have a clue how to make things like that!

                                          This is too complicated? then connect a wire to CN7 Pin 4 (or Ground) and touch the other end of the wire to one pin at a time (pin 1, 5, 6, 7, 8, 9 or 10) and see which one has the desired effect
                                          That plug (CN7) is where the keyboard plugs in, You don't have one so what else are you going to do?
                                          I can't tell which is pin 1 but if you check on cn7 pin 4 will be connected to ground, that will tell you which way the plug is numbered

                                          I also don't know which button S1 - S7 would be, looks like its Power, Menu, Vol+, Vol-, Input, Exit

                                              I'll give this a shot. Ive never really done this kind of thing or even taught myself wiring blueprints thanks for all your help and hopefully I'll be able to make this work!

                                                  Note: these are normaly open momentary switches.
                                                  The way it works is each button has a certain function, when the switch is pushed it takes that line to ground. So if S1 was the power switch when it is pushed it takes the K0 line to ground telling the microprocessor to turn off or turn on the monitor, if S2 was the Menu, pushing it would take K1 logic line to ground turning the menu on and off. etc.
                                                  It would be easier to navigate the menu with the keyboard, so you only have to push a button to change items. maybe a local electronic shop would have a plug that fits CN7 and an old keyboard with a similar switch arangement.

                                                      What you want is similar to this but with 7 buttons and 10 pins http://www.ebay.com/itm/Universal-LC...kAAOSwd4tUCDcO

                                                                  The remote only works at exactly 3V - if I drop it any lower, using my bench power supply, to say, 2.9V then the remote will not flash the display and turn off. I don't have any AAA batteries that are exactly 1.5V each so I'm not sure if this remote is designed this way - to only use the freshest possible batteries, or if there's a failed component in the mix.

                                                                  I can't find any schematics...

                                                                  I was wondering if anyone could help my in pairing a remote with a Toshiba fire tv?
                                                                  The Tv model number is: 50lf711u20 Rev B.


                                                                  I've already replaced all the the circuit boards within the tv along with the I.R. sensor receiver.

                                                                  I've tried 3 different remotes which should be fully compatible with this TV.


                                                                  Oddly enough. A few if the buttons on all of the remotes actually work. Even without pairing...which makes no sense.

                                                                  The power button, along with the volume,back,select, and directional...

                                                                  1) I press the red power button on the remote
                                                                  2) The TV turns on normally
                                                                  3) After that it won't take any other command from the remote, neither power off, volume, channel, NOTHING
                                                                  4) We need to either pull the main cable or use the built in button at the bottom to select funcion OFF

                                                                  Then after it's off, it would again accept the TURN ON from the remote and same again

                                                                  BUT:

Recently, the remote control started not able to turn the receiver on. Later, the volume also could not be adjusted by the remote control.

                                                                  At first, I thought that it was the usual problem which can be fixed by cleaning the contacts on the switches and the pcb. I opened the remote and clean it with alcohol. The remote did work again after that. But after one day, it did not work again. I opened it again and clean with alcohol and contact cleaner. Again it worked...

                                                                  Question recently I’ve connected it up to my tv which has greatly improved the sound on my tv, however I’d like to be able to mute the subwoofer when ads come on or just mute it when the phone rings etc. I tried using a cheap all in one tv remote on the subwoofer and the volume button would only work to increase volume but not turn it down or mute it

                                                                  Is there...
