Samsung TV LTA320WT-L16 Matrix: Damaged T-con 320WTC4LV1.0, Inconclusive Symptoms, DC-DC Converter

The Samsung TV with the LTA320WT-L16 matrix showed symptoms that were inconclusive in terms of matrix damage (flex drivers). The image is displayed in 16 colors, light green, sometimes red noise but without freezing or slowing down. After crossing the T-con, the 2.5V DC-DC converter was damaged. It is interesting that the inverter gives around 4.8V output, and T-con "works", of course not quite right, but the picture is. Unfortunately, I did not dig out the converter system anywhere, so I tried the 2.5V linear stabilizer for the test. So I restored the correct power supply. After this procedure T-con does not work, on the screen changing vertical colored stripes. How miraculously the 2.5V rated systems worked with almost twice the power supply? I have not found the LRX4222T3 PDF but the memory definitely had no right to survive. So what was it supposed to be?

There on this T-con 320WTC4LV1.0
scaler_controler LVDS LRX4222T3
memory K4D263238I-UC50
EEPROM 24C64
and IC320 Intersil 24006IRZ * DC-DC converter

You'd have to start measuring it!

As for DC-DC, use the datasheet for this EL7585AIL chip

The inverter on the U1 5VDC system is over 2.5VDC. As I mentioned, I replaced the 2.5V linear stabilizer. After replacing the K4D263238I-UC50 memory
the image appeared but the background of the frame should be blue and it is green, except that the picture seems to be repeatedly duplicated and shifted. Voltages associated with the gamma corrector are roughly correct. Probably LRX4222T3 also damaged by too high voltage (5V instead of 2.5V). No replacement system. T-con not really repairable. You need to look for a new or smooth demolition.

T-con listed. The matrix is efficient. However, it does not give me peace of mind, this is the voltage supplying the scaler and memory (VDD2.5). How could the systems work almost correctly with twice as much voltage?
