Hello solved the problem of Flexgate by replacing lcd, but it does not have backlight, here are some measurements: PPVIN_S0SW_LCDBKLT_F = 13V PPVIN_S0SW_LCDBKLT =12V EDP_BKLT_EN= 0v BUF_EDP_PANEL_PWR_EN= 3.40v EDP_PANEL_PWR_EN= 3.10v PANEL_P3V3_EN_DLY= 3.29v

Tried with a new screen and it does the same, it looks like a logic board problem

Now the image is disturbed in this way

I solved it by replacing C9301, now I have a problem with the audio it does not emit sound, except that of charging, it does not emit the boot sound and the sound in general, the system detects the internal speakers

Hello I checked U9310 all the output voltages are 0V I only get 1.5V on PP3V3_SSD_LIM

I try to do a restore in dfu mode, if I possibly want to replace u4200 I can use a 820-00928 donor, I'm afraid that part is affected by corrosion

Corrupt bios?

I have this card that works perfectly the only thing that in the Monterey installation once you enter the password, it tells me that it can't install an update and doesn't keep me

It's interesting that Paul Daniels invested $500 to give to someone who finds him a way to do this thing

Hello maybe a stupid question, this card can work without a cd3215, or they want you all 4, I've never fixed such a card

Hi, I have this card that had a short on ppbus that I identified thanks to the Flir si C6505 the problem is that I do not have a replacement capacitor and wanting to recover it from a donor card there are only 22UF 6.3v or max 10v or 25v there are only polyester what do you recommend me to do?

I get the external video, I checked the values and tracks, after connecting an external monitor to the thunderbolt port the screen is illuminated but black without images even now even after disconnecting it

I have this card that turns on emits the boot sound the lcd panel turns on but no image, illuminated black screen, where you can see some rejections, I tried to change lcd but the result is the same.

After the holidays, I took a look at him again, and found the culprit, the problem that the cut is at the limit.Flex is cut

Then allo probably will be the Nand memories in dfu mode when it tries to restart to re install the operating system goes in bulk

Yes I did but nothing, having to do in visual inspection on the board which points might be interested maybe the IGPU section

I redone the procedure, it enters the dfu, I proceed with the reset, but I also tried with the reactivation, but the procedure ends with the lock, I also tried the reset of the pram, it emits the sound but no screen, the T2 is gone or is there any other problem?
