Ok, just got 45 and 44 to pulse at 5v and 3v respectively. 3V3_S5_LCD is 3.3 DP_INT_HPD pulses at .800V at first few seconds. PANEL_P3V3_EN pulse at 3.35v BUF_EDP_PANEL_PWR_EN pulse at 3.35v BUF_EDP_PANEL_PWR_EN pulse at .800v

45 gets a pulse at 5v but 44 gets nothing. DP_INT_HPD gets nothing. R8501 ohms was low so I replaced. Still nothing.

5.13 was an error. It's 3.32. I do get a quick pulse in the first 10 seconds on PANEL_P3V3_EN 3.35v. Tested at C8516 pin1 and R8590 pin1.

R8554 is 0 ohms. Diode reading were tested with red probe on ground. Everything EDP_INT_ML_x is OL

0 V on R8554, diode readings for all EDP_INT_ML_x lines is OL.

Are you suggesting I check my U8500, U8510, and D8518 solders? I did do a thorough inspection on the board and I see no other places that seem to have been tampered. I do notice the area around L2990 gets a bit hot but can't find a short and voltages are normal.

It looks like it has been worked on before. D8518 near U8501 was knocked off but I replaced. Also replaced U8500 and U8501 to be safe.

Thanks! No signs of liquid damage. LCD connector looks good. Came in for LCD replacement because of no image and previous LCD was cracked and had no signs of life. New LCD didn't fix the issue.

Hey guys, I have an 820-00840 with no image. External monitor DOES work. The image is not dim, it is non-existent. Tried 3 different displays and eDP cables. With display connected: LCD_IRQ_L - 10.00 mV DP_INT_HPD - 10.00 mV PP3V3_S5_LCD - 5.13 V PANEL_P5V_EN - 0 V (checked on test point and...
