iPhone 6 no image, problem and solution (one if many)

iPhone, iPad, iPod Hardware Repair Hardware Repair discussions for iPhone, iPod , iPad & Apple Products, help, guides.

I had this case a few weeks ago. iPhone 6 with no image after a drop.

No shorts, LCD tested and working perfectly, filters ok. No voltages presents, so i checked the display PMU and found this.

The line LCM_TO_CHESNUT_POWER_EN didn’t have continuity to the conector.

So i made a jumper from the test point to the connector.

And the iPhone now works perfectly.

I hope this information will be useful.

Hi Mark, thank you very much for this very good explanation. I have a question please. What can we deduce if on of the first two filter you are testing (FL2027 and FL2037 are testing good in diode mode but not producing the right voltage) In my situation, this is the filter FL2037. I am not getting 5.7 volt but the filter is testing good (attached capacitor of this filter, C2094 and C2071 are also testing good), thanks in advance

Mark, TY for the video. When you say you connected screen and check FL2035 and FL2036, are you just looking for 1.8v? I have the exact same symptoms as you describe (Can update without errors on itunes, just no image but have backlight). I have an Iphone 6 that was experiencing ghost touch. I replaced meson and cumulus after testing a known good LCD and no change in symptom. I changed both again to make sure there was no mistakes and still no change. I began testing voltages with screen attached when I noticed home button would not work. So I powered down, resat the connectors and when I powered back up again, I have a backlight but black screen. I tested with another lcd and same thing on it. It draws power, charges battery, Itunes sees it, just no image and crazy readings around Mesa and bad readings around Chestnut and Tristar.

I changed Chestnut U1501 and U1503 along with C1501

Getting the following:

BL Coil is 1, Diode is .204v, resistance to ground is .507v

FL2035 LCM to Chestnut and FL2036 AP to LCM Reset are good = 1.8v

FL2095 PMU to Photon Alive = 1.8

P17V0 Mojave _LDOIN C1501 = 3.8 (That’s why I changed it and U1503, No Change)

L1500 PP18V0_Mesa (1 and 2) = 4.2v (Another reason to have changed U1503 No Change)

C1500 and C1503 getting 0 to crazy numbers on Voltage

L1519-1 getting 4.2v good VCC_Main but not boosting to 6v on L1519-2 (Is why I Changed Chestnut U1501, No Change)

FL2037 PP5V7 (C2050) . = 5.7v

FL2061 PN5V7. = -5.7v

FL2027 PP1V8. = 1.8v

C1299-1 PP3v3_ACC 3.3v missing on Tristar U1700 (Replaced Tristar with no change, Getting VCC_Main around Tigress U1401)

I was able to restore on Itunes without errors. except I have a Backlight with no image, tested with other LCD’s

I also replaced Data Filters L2041, L2042, L2043, L2044
