Well the fault that the screen has. It does not turn on does not send image. When I connect it to the electric light, it only turns on the red light, when giving it pawer to turn it on it does not turn on and does not change the blue color of ignition it remains in red color. My question is this. Where the fault may be! If in the source card, or the card t-com. What pieces should I check! It is a 24-inch screen Daewoo brand Model DEA-24RIF

Hi, I don't think it's the t-on, maybe the source, it would be necessary to see if it has the correct standby voltage, if when you give the power the main command does not return so that the main source starts up is the main (it can be the firmware or a sub-source, if the start order (power on) arrives and the source does not start it is the source, I hope I have oriented you, luck PD here they fixed one like yours https://yoreparo.com/tv/televisores/lcd/preguntas/1129206/tv-daewoo-modelo-dea-no-enciende

The Standby is marked at source 12v. I measured a voltage under 1.5 with the multimeter and a half. I measured in the following way the cable that goes from the source to the main I put the ground point in the chassis and the other end in the connection I put on the first pin 0, 0, 1.5, 1.5v when on the source card It has marked a voltage of 0,0, 12,12v. . Then the problem is at the source.
Can you guide me if I am correct! I will check in that area transistors and capacitors. Anything else I have to check please get horny. Thank you very much for your help.

Hello Angel, if there has to be 12 volts and you only have 1.5 it is the source that does not work or you have a short where you connect the source

I'm checking the source I still can't find the damaged part that makes me take less voltage.
But I told you that before this problem appeared, I brought a fault that, when connected to the light, burned the fuse but proceeded to change the rectifier bridge (4diodes) and went well 3 months until suddenly I saw that it went off alone when I was on Then he turned himself on. He also commented that the screen always remained off and disconnected only connected when it was to be occupied.
I will continue to check the source. component x component I am open to any solution
