Welcome to the TV, there is a voice, the matrix lights up but there is no picture content, there is nothing, the power supply voltage is all correct. When switching on, the LED blinks red twice, the backlight, voice and so on. Logic power supply 12V, fuse OK, which may be the reason for this...

It can unfasten the left or right tape from the matrix and check if there is any content on the half.

According to this topic, we know about link Enter the matrix and T-con. ? Forum topic link , he says Verify. __________________ LG 32LN5400, 42LN5400 the same pcb, matrixes respectively LC320DUE SFR1, T400HVN05.2, LC420DUE SFR3

T-Con V390HJ1-CE1 and motherboard EAX64891403 (1.0) I will check the dies when I get back from work. Regards.

Could you still do some measurements on the T-con? Apart from 12V are there other voltages?

Note the measurement values from - CM501 (G5562A / EDS-5562A) * MAX17126B

The matrix is HC390DUN-VCFP1-21XX. When the left tape is removed from the matrix, half the screen is white, the right one is the other half white and on the other side after pressing the menu for example colored vertical stripes appear. I measured the T-CON. VAA-17,7V VGH-20V VGL - (- 7,94V) STV-0,44V VCM CF-7.82V. VCMTFT the same V1V2-1,2V SDA 3.3V SCL-3.3V UP4-3,3V UP2-1,2V

You can try to provide - left T-con ribbon for the right matrix connector - then similarly with the right ribbon from T-con> to the left zloty. matrix

Hello, does anyone have a batch of MX25L4006E for this logic. Regards !!!.

Ok, the matter is clear, the matrix for scrap metal, damaged tapes, by washing the matrix with some wonderful liquids, the tapes are from the bottom and everything that flows on the screen poured straight onto the tape and plate connection and ate everything nicely. The topic can be closed. Regards !!!

LG 39LN5400 - the voice is there, the matrix backlight is on, no image content.

Topic summary

The discussion revolves around an LG 39LN5400 television that powers on with sound and backlight but displays no image. Users suggest checking the T-con board and matrix connections, as well as measuring various voltages on the T-con. The author reports that removing the left tape from the matrix results in half the screen displaying white, while the right side shows vertical stripes when the menu is pressed. Ultimately, it is concluded that the matrix is damaged, likely due to liquid exposure, rendering it unusable.
