Hi, I have a Lenovo G50-45
Power on, slight colour change on screen then back to black
External screen works. Machine boots, fan works etc
Replaced screen with new same error, slight change shade of black then black
Replaced VGA cable exactly same symptom
Replaced with a third screen same symptom

I have never come across this before (usually solved by changing cable or screen)
Any thoughts please
Thanks

you can program it with universal programmer like SVOD programmer .
Thankyou, I must be missing something. Why would flashing the bios help seeing as the computer works perfectly fine on an external screen. If the bios is corrupted I could just flash the bios supplied by Lenovo for this motherboard. I wouldn't need special hardware to do it?

I have found the H2OFFT-W.exe flash utility used for these motherboards Insyde H2O boards. Can I use this to flash your bin's. It has config file platform.ini
