Toshiba Satellite Pro 4600 display problems

Acej · 11-20-2005, 04:27 PM

I have a problem with my Toshiba Satellite Pro 4600 laptop (Model No.PS460E-02HYT-EN). The display recently stopped showing any image. I have been reading through some old solutions to similar problems on this site and some others, but need further help.

The backlight still comes on when I power on, so I am assuming that the inverter is working okay (I know....should never assume anything!) I tried connecting an external monitor, and when I do this the image from the laptop is displayed with no problems at all. I do not therefore think this is a problem with the video.

I have also disconnected the inverter plug from the lcd to see if I could see any faint image on the screen (I am not familiar with whether a faulty inverter only causes the backlight to fail, or if this can come on but there is still a problem). There was no image at all, however faint, on the screen when I tried this.

I then tried connecting the screen from another laptop to the Toshiba's video ribbon cable (could not connect to inverter as is different plug - again assuming this was probably a good thing or something would have been toasted!) This time I could see a very faint image on the other screen, but obviously with no backlight. I therefore do not think this is a problem with the actual LCD flex cable.

My question is, does all this mean that the problem lies within the LCD itself? (This is a Samsung LTN141X7-L06 - I have checked the prices for this on the internet and it seems an expensive part to replace). If so, is replacement my only option or can a suitable but cheaper screen be fitted in this laptop?

The Toshiba was working fine with nothing indicating any display problems prior to failing, but I don't know how common this type of problem is (seems more often than not is inverter problem from posts I read).

This problem occurs whether or not I am using battery or mains power.

Any help from someone experienced in repairing laptops would be much appreciated.

Hi,

Thanks for your reply. Is a strange problem. Pressing button you mentioned doesn't seem to change anything on screen. Trying to figure out what's wrong here (going to have a look at power cable connecting to inverter on LCD side). Will definately get back to you when I've figured this out as is driving me mad!
