Hi! I have Toshiba Qosmio x870 Gaming Laptop. My client gave it to me to repair. Laptop was dead. Will not turn on.
I have replaced Video Card NVIDIA Geforce GTX 670MX first. Will not Turn on. So I have replaced motherboard as well . Motherboard has latest firmware.
The computer turns on now and boots normally with just external monitor attached. As soon I connect internal monitor and try to turn it on, computer will turn on but it will not start. It will flash red power light for 5 seconds on and 5 seconds off.
It does the same with just LCD cable attached, without LCD. Replaced memory. I have replaced LCD cable and LCD - same thing. Now I'm puzzled. Could not find anything like that on any forum.
Any hint or help is greatly appreciated.
Thank You.
