Yes.
I already indicated that the auto gene starts, but it doesn't pass from the red screen.
Thank you.

It reaches to show the green color, but at that moment it goes out.
The plate will be repaired, or better replaced.
Thanks and regards.

Card changed, but the problem persists.
It is as if increasing the consumption by turning on the screen, the power is cut off.
Turn on, display the LG logo and turn off.

with that detail that you just mentioned that the logo is seen and goes out immediately is that you must clean the solved flexs and connectors on the tcont card and the main ... it does not make sense but it turns out

In case it helps:
Power supply voltages. (No load) in volts. 220 / 240v AC network voltage
VS-201.3
VA-54.7
M5V-5.17
MON-4.89
AUTO GND-3.94
RLON-4.65
ACON-5.09
17VDET-2.29
VSON-0.67
VSDET-2.75
5.2-5.17
GND-0
17V-16.99
Voltages measured with 1Kohm resistor bridge between 5.2 and M_ON and 5.2 and RL_ON.
I have already cleaned the flex but it does not improve either the image or the disconnection time.
Greetings and thanks.

well the source is good there is no other to try the main

The question I have is if the fault can be at the source, and only occurs when it is loaded.

all those voltages are correct ... the source is working you tell me that there is an image but it lasts very little with that I discard the cards "YSUS", "ZSUS", "XSUS", and the buffers change the logic card (TCONT ) I do not give more than the main and speakers
