I was given this notebook with a no video issue. The laptop would start, but the fan would shut off and the CAPS LOCK light would blink and the lights for the volume, wi-fi, etc. were on.
I dis-assembled the notebook and re-flowed the GPU. I had purchased the copper shims for this model from e-Bay and installed them after the reflow. After re-assembling the notebook, the system works flawlessly except for the fact that the screen will not turn on. I purchased and installed a new inverter and also a new video cable with no change.
The system works fine when an external monitor is used through the VGA port.
On the cable going to the inverter I am getting 19.72 VDC on the first 2 pins and 0 VDC on the remaining 5 pins. I figure there is a component or something that is not working that should be sending an on/off signal to the inverter.
Any suggestions would be appreciated. Thanks for your time.
If pictures would help, just let me know, I will gladly upload them.
