LG Monitor Rescue - How to Combine Parts and Save Hardware
I made the decision to get rid of several things I've had stored away for years, some to give away and others to sell. Among these things, I have various components from old PCs, including two 19-inch LG Flatron widescreen LCD monitors (16:9 aspect ratio) with a resolution of 1366x768 pixels, also known as HD.
Tome la decisión de deshacerme de varias cosas que tengo guardadas por años, una para regalar y otras que pueda vender. Entre estás cosas tengo varios componentes de PC viejas, unos son dos monitores LCD de la marca LG del modelo Flatron de 19" del tipo panorámicos o formato 16:9 cuya resolución es de 1366x768 píxeles conocidos también como HD.
These monitors are perfect for security camera surveillance systems, PC cash registers in stores, etc. So I get ready to check them out, and it turns out that one turns on but quickly loses the image, and the other has a stained screen, as if it got damp—which surprises me because when I put them away, both were working perfectly.
Estos monitores perfectamente sirven para sistemas de vigilancia con camaras de seguridad, cajas de pago con PC en comercios, etc. Me dispongo entonces a revisarlos y resulta que uno enciende pero pierde rápidamente la imagen, y el otros la pantalla está manchada, como si se hubiera humedecido, lo cual me extraña porque cuando los guardé ambos funcionaban perfectamente.

I was right on the verge of throwing them both out, but it occurred to me that I could take the circuit board from the monitor with the stained screen and put it into the one that turns on but loses its picture, and that way only lose one.
Estuve a punto de desechar los dos, pero se me ocurrió que podría colocar el circuito del monitor que tiene la pantalla manchada, en el que enciende pero pierde la imagen, y así solo perder uno.
Opening them up to get to the circuit board is not easy at all. There aren't any screws; the front bezel is removed by releasing a series of clips around it. With the help of a thin flathead screwdriver and a putty knife, I popped them open one by one, little by little. This task took me the most time, since I had to do it carefully so I wouldn't break the front bezel.
Destaparlos para acceder al circuito no es del todo sencillo. No tiene ningún tornillo, el marco frontal se retira soltando una serie de clips que tiene alrededor, con la ayuda de un desarmador plano fino y una espátula, poco a poco fui soltando uno por uno. Esta tarea fue la que me tomo más tiempo, ya que debía hacerlo con cuidado para no romper el marco frontal
Once the bezel is unclipped, you can take out the screen and the circuit board. To my surprise, there are no screws connecting these two parts either, just some adhesive tape for the wiring and boards. The first step was to remove two cables that come out of the side of the circuit board and go into the screen; I assume these are for the backlighting. These types of cables are removed by pulling them while gently wiggling them sideways, so you don't compromise the connector on the circuit board.
Una vez soltaron el marco se puede sacar la pantalla y el circuito. Para mí sorpresa tampoco hay tornillos que unan estas dos partes, solo unas cintas adhesivas para el circuito y cables. Lo primero fue quitar dos cables que salen lateralmente del circuito y entran a la pantalla, supongo que estos son para la iluminación. Este tipo de cable se quitan jalandolos mientras hacemos movimientos laterales suavemente, así no se compromete el conector que está en la placa del circuito.
The next step is to remove the ribbon cable by pulling it from both sides at the same time. Then, separate the small control button board on the front panel, and you can finally separate the circuit board from the screen. I swapped the good board into the good screen and put everything back together.
Lo siguiente es quitar el cable flex, jalandolo de los dos lados a la vez. Luego separar el pequeño circuito de los botones de control que está en el panel frontal y así finalmente separas el circuito de la pantalla. Pase el circuito bueno a la pantalla buena y arme nuevamente todo.
After assembling everything, all that was left was to test it. Since I don't have a computer, I asked someone close to me for help and tested it. Everything worked great, giving a clear picture and making it ready to be used. So, instead of throwing away two monitors, I managed to save one.
Tras armar todo solo quedaba probar, ya que no tengo computadora, pedí el apoyo a una persona cercana y lo probé. Todo quedó funcionando bien, dando buena imagen, quedando listo para ser usado, salvando así de ser desechado dos monitores, pude recuperar uno.
