Hey Ginko! Gracias por el apoyo!! Yes, i've seen the inverter costs $14 only! But i was wondering if that lil board is the inverter? How can i check if it's right or wrong? And where is the lamp?Are it's terminals accesible from the boards? If no resistance it's blown i supose.

This is not an inverter problem. The inverter only powers the fluorescent lamps in the back of the LCD panel.
It is probably a fault in the LCD data decoder circuit or a failing connector between the decoder circuit board and the glass LCD panel. If you took it in to a shop, they would probably charge you a full hour's labor minimum - compare that with the price of a new LCD monitor.
no estoy seguro pero creo que el problema esta en el circuito integrado GM2121 que esta precisamente en la placa que mencionas...ya que a pocos minutos de estar encendido recalienta mas de lo normal...
First check brightness and contrast settings. If all good could either be your lcd back light has gone or the inverter. To check if its the black light shine a torch through the back of the screen to see if you can see a slight image on it, if you cant see anything the inverter board is faulty and to repair needs to be changed.
It's seems your backlight inverter finally burnt out on ya... Need to replaced a new inverter or you can repaired yourself and show your hubby who the boss in the house...hehehe... Only need to replaced a couple of capacitors...that cost about $10 bucks! Well...good lucks!
This is a problem I have seen with a few LG monitors.
Your Inverter circuit is fine (that powers the lights to your screen so you can see the image on the LCD panel) but the monitor does not like having a video signal attached to it.
Bad capacitors on the power board can upset the current going to the controller board. This board included the video input circuit and the power supply needs to be stable for this to operate.
The controller IC that translates the video signal into what the LCD panel controller can understand is failing. Normally this fault occurs in the horizontal and vertical input of the IC. The fact you can see the other message on screen is due to it going through it's own internal and seperate section of the IC. In this case the only repair option is to replace the internal video board. Sony will not supply the parts directly to the public, but if you are really nice, they "may" tell you where to get one externally to Sony.
buddy just check the power cable of the monitor... may be there is problem with the power cable try changing power cable... and also after connecting with the old cable only just press the power button of the monitor may be it s turned off... try turning it on...
