Re: e701i-a3 no picture but backlights

I successfully fixed mine. Removed side tabs, and it works. BUT i did encounter a moment of sheer terror as I thought I removed the wrong side. So a heads up for anyone else.

At first I used a box cutter and just sliced the ribbon cables through the middle and removed the side driver boards. My video was still distorted and I had some horizontal lines. So i thought CRAP the other side is bad too. But then i removed the driver ribbons completely from the LCD pannel, and it was fixed, so make sure you completely remove the entire...

Re: e701i-a3 no picture but backlights

I tested the resistor and it did not appear to be shorted. I got normal readings from it. So I was a little surprised when I did not receive any Voltage on the silver round resistor from this test. But I am having the blank screen issue. I tried disconnecting the white cable from either side and nothing changed. Still blank black screen. But everything else points to it being the bad horizontal video driver.

I was originally going to replace the resistor on my t-con, but now i'm not sure what is damaged on it since it failed...

Re: e701i-a3 no picture but backlights



I tried this test with my T-con and got 0 voltage. Is this indicative that there is something more wrong with it than just the MOSFET chip? Should I just get a whole new t-con board rather than replacing the MOSFET?...

Re: e701i-a3 no picture but backlights



Not sure if this ha been covered but I do not recall. So if you remove the cable form the side driver boards, wouldn't they be disengaged and not cause the issue anymore? So why does removing it completely change anything. Since they are already unplugged. Just wondering why removing it is necessary to complete the repair. Jut want to understand whats going on....
