820-3332 no image

[Cocobill]

Hello,

I got this 820-3332 with green light OK, chime OK, no image. I know it has booted into the OS as I can hear the volume up/down adjustment sound. When I close the lid for some minutes and open it up again, I get an image and everything works fine! What do I check? The plastic cover on U1800 looks heated up. No history. No liquid damage visible.

Did you touch up the solder joints on U8900 yet?

That was the first thing I did, no luck...

Known good LCD? LCD_HPD line can cause issues like this, check diode mode and connector/cable.
