A1932 no image

I've stupidly connected A1932 screen while the battery is plugged in..
ALS CAM coil was burnt to ashes.. replaced it and diode mode readings all ok
U5200 (I2C TCON) chip had little high diode mode readings on the display lcd not T2 side; replaced and it diode mode are better..
but still no image
I've taken diode measurements from LVDS connector; all ok now (edited)
what am I missing?
no 5v sw no 3v sw

it booted normally and DFU restore successful

External video ok? Caps led key toggles? Just to confirm the boot is truly ok.

no external image..

I mentioned that it boots normally because it showed an image and booted normally one time without issues and then it stopped

Since you are missing some voltages, what is the voltage to ground of PPBUS_G3H? (check @ F7000)

What is the voltage and current draw at the power adapter?

It did not give any image.. when I mentioned that it booted normally it happened when? Here is what happened:

I left it two days ago to do DFU restore and left the office.. next day I came it was on question mark meaning it completed and it was DONE... all OK.. computer was perfect up until I took the board of to clean.. when I returned it to housing; not image.

I did the same thing yesterday leaving it to do DFU restore and left the office.. same thing happened and now it boots and shows image without issues.. no problem whatsoever.. I'm sure if I take the board out and disconnect the battery the problem will reappear..

never mind.. I should have done a DFU restore after replacing the ALS CAM coil and U5200 chip because now it's all good..
