What defect is causing this?
This image shows what happens if I don't have it connected to an HDMI external display. I can boot to safe mode the internal monitor has no issue (not connected w/ HDMI) once reset within 30 sec after desktop is shown the internal display goes out (image provided) I have ran hardware detect (booting + D) no errors found, nvram reset and smc reset done no difference. But all is good as soon as I plug in HDMI both external and internal monitor blink then come back working no issues only once HDMI is unplugged I get either a fading out on internal or it does the image provided. Is it the internal screen? Or logic board? Please help this is racking my brain.
(2.7ghz,8gb,256ssd)
Troubleshot: (without resolve)
- Reseated all internal logic board display connectors
- Reseated connecters on internal screen itself
- Removed ribbon cable connecting HDMI/wifi board to main board
- Reset NVRAM
- Reset SMC
- Swapped SSDs 256 to 128 and back reloaded fresh OS installs on both drives

Also now when the HDMI is plugged in, the internal display flickers just slightly?
