Walking through your steps fixed my flickering issue. The only spot our LCD wouldn’t flicker was if it was at full open tilt – anywhere else would either produce ghostly lines or sever flickering. I opened up the bezel around the LCD, removed the three connections around the inverter, reseated them and put everything back together (there was some yellow translucent tape that held one of the connections to a small circuit board, which I used to more tightly secure that connection). THE FLICKERING HAS STOPPED. Thank you! You’ve saved me from completely replacing the video cable, which I thought was my only option. We’ll see how long this fix lasts, but if I have to pop open the bezel once every couple of years to reseat the connections, I can live with that.

Toshiba M305 – S4819 (USA)

I have the same problem. I have changed the video cable made by CMI to another one made by different manufacturer with different numbers on it. I hoped that this will help, that another brand produces better quality cables, but after a week when installed it sometimes I can see some random tiny lines on the screen. I think the problem is not with cables itself but in the laptop construction. When the lid is closed the shape of it bends the cable in a weird position so tiny cables inside are destroyed slowly because weak point is exactly there where cable is curved. Nowhere else. The solution is to never close the lid or do it as little as possible.

I tried everything with this laptop
Cable replaced, inverter replaced same problem as all of you guys.

I touched the right top of the circuit board behind the lcd at top and bam worked

I the folded a piece of paper and wedged between LCD and cover and screwed back the LCD, so that the board behind the LCD is compressed. All is good now….

I guess in your case it was the LCD screen failure. If it starts failing again, you’ll have to replace the screen.

As always the solution is found by accident

Confirmed Fix – Same problem with flickering screen that had been getting worse over the last year. LCD flickering issue occurred when moving screen, bumping / jiggling laptop and temporarily resolved by moving screen to different position. It got to a point that the problem was fairly persistent and could not be resolved by moving the screen to a different position.

NOTE: following this procedure – while simple – will more than likely void your warranty!

Fixed by
– remove battery
– remove front outer plastic surround of LCD – remove 4 Phillips head screws under rubber stops in each corner and insert fingernail – or similar thin device – around the edge to break seal and then pry off gently – pieces around hinge are tricky.
– remove connector from right hand side of inverter with tweezers and then reconnect firmly.
– use a small piece of electrical tap to further secure wires to decrease movement.
– reattach front outer plastic surround and replace battery.

Flickering has now stopped.

Hope this help someone else.

So this doesn’t help anyone, but I believe the problem with this laptop model and most of Toshiba’s models is that the cooling systems are absolute butt.

I had my laptop repaired twice while it was still under warranty, and each time they replaced the motherboard(stating that it was overheating because of the shitty fan and had thusly fried it) and everything worked great once again. I think most of this problem is a matter of regular(monthly) vent cleaning as to prevent overheating, but I’m about to open mine up and see if that’s really the case.

I’ll be back!

You said:
“The simple act of disconnecting the video cable from the motherboard and lifting, caused a rotational movement that transferred through the left hinge into the tiny cable connected to the power inverter. Somehow the tiny cable got pushed forward inside the white connector and restored contact between the sliding gold contacts inside the connector with the power inverter pins, at least temporarily until problem re-occurs.”

Well the thing is I have the wire glued by glue gun to many places inside mother board case as well as in the hinge housing and LCD Bessel. Also it is hot glue gunned all around the power inverter. Rotation of the screen seems to have less affect on this problem then it once did. I have noticed that I have had no flicker until just recently and the flicker seems to only come when I watch movies. As before the flickering starts slowly and gets worse and worse over the weeks. All I know is what always temporarily fixes my problem (for at least a month and a half) is disconnecting the wire from the motherboard, then reconnecting. To me it seems to have nothing to do with the inverter, since I do not touch the connection to the inverter anymore to fix my problem (since that area has been hot glued gunned quite securely). I strictly only disconnect the mother board plug and reconnect.

i was wondering if any of the mb on this series of laptops have died??, my m305d i have has a cracked screen and plan on replacin it, i got the laptop for nothing practically, but im tryin to figure out if its worth fixing, and if the mb is just gonna die then is it even worth messin with??, anyone know if they die alot??, heres the model m305d-s4828
