T_100
"No TE signal for 2K LCD" This indicates an LCD screen physical connection problem.
The Tearing Effect Signal (TE) is a feedback signal from the LCD Controller to MCU. This signal reveals the display status of the LCD controller. In the non-display period, the TE signal will go high. Therefore, this signal enables the MCU to send data by observing the non-display period to avoid tearing.
According to hardware Master César Fernández, once a bad LCD or bad LCD connector is ruled out, next things to look for in order of economy are:
Reinstall firmware for a version very different than the current one and test.
Check Onboard LCD connector, replace if damaged and test.
Check R15, R16, R24 Resistors and Q10 transistor, replace if shorted or wrong value and test.
If none of the above work, then:
Replace Mipi bridge ICs and test.
Replace FPGA and test.
