Toshiba Satellite C55-C/L50-C/P50-C, 64 bit Win 8.1. Or at least that's what the manual calls it !

 

This is my wife's laptop and the screen has started either flickering or not displaying. This seems to be dependent on the angle of the screen and when it is displaying the display is perfect.

 

I have not yet opened it up but expect to find that the problem is due to the video cable to the screen, either loose at one end or the other or possibly damaged. I would be inclined to suspect the screen end because she has the bad habit at times of hauling it around by the screen especially if she is using it to watch internet TV.

 

If it turns out the cable is damaged is the, presumably, ribbon cable a generic commodity or is it likely to be a Toshiba part ?  In other words, can I source cable fairly easily or am I going to have to go to Toshiba for one ?  Anybody know ?

usually the video cable is not a ribbon cable, its very small wires and can break easily.  especially if laptop is in cold weather.

here is a quick google search probably not your cable specifically because I don't have your entire model number, but this is what they look like.

it probably very similar to your cable.

Thanks for that.  I may get into it this coming weekend if she is willing to put up with one of my dual-booting laptops - a crash course in Linux ?  Failing that it can wait until the end of February when she will be away for a couple of weeks but good to know there are other sources than Toshiba.

I admit it - I was wrong !  Don't say I never put my hands up !

 

It turned out it was the screen that was dying. I pulled it out to check the cable and when I put it back in position it was dead. One replacement screen later and the laptop is as good as new. It's nice dealing with efficient suppliers.
