Toshiba Satellite C55Dt connect to external monitor with a broken screen?

[ajshn]

Yes that picture. Oopsy. So those are the wifi antennas? That explains why the wifi connection was always bad even though the signal was just fine. :ROFLMAO:
Thanks, I’m just trying to check everything incase there’s an easy inexpensive fix before having to pull out the big guns.
So in case someone knows are the silver cables in the other pictures just for the webcam, are they connecting something else?

This one I am taking a guess and if the system has one may be for the touch screen if the system has one, which in my opinion that should not make the monitor come on if disconnected yet stranger things have happened.

Yea theres a touchscreen. It was disabled in device manager a while ago to make the battery have a bit longer of a life, since I never used the touchscreen. Could that be an issue? I don’t know why it would just start to be one now as it has been disabled for months.
Then again this laptop has a lot of design flaws. Like the wifi card, and also the hinges, I took the hinges out since they where in the way of the lcd cord, and the metal is far too flimsy. If i fix the steeb the hinges so need to be replaced. Lots of complains of them failing even without someone stepping on it.

Being disable will not prevent it form booting. Being physically disconnects like in the picture it may not recognize the cable being attached and that may in turn be why. Do not know if you left the cable unconnected or not and or if it really makes a difference.

Have you tried one stick of RAM at a time in the system yet?

Let me also get another to look at this thread and see what they say. @Madmatt2006

I only unplugged the cable to take a picture. All cables where attached when testing. I will try the ram thing tomorrow. I’m way to tired now and will probably break something if I attempt it it tonight. Thank you for all the help.

[ajshn]

I tried removing 1 ram at a time, leaving 1 in each time, and no change. I’ve just noticed that after a couple of minutes the laptop turns back of/goes into sleep mode with no light on the power button.
Could this be a hard drive failure? Ive never had that happen so I’m not sure what that looks like.Or would hard resetting the bios be a fix?
Im guessing the issue was never the screen since I couldn’t plug it into an external monitor and replacing the cable didn’t work. I was hoping the cable would have been the issue, it would have been such an easy fix.(n)
Just in case i missed something here are some pictures of the inside of the laptop: [MEDIA=imgur]a/8S9bR[/MEDIA]

From your reply #8

Recently the screen went and I just moved the cable a bit and it came back on. But last week it happened again and I couldn’t fix it.

Something may have been shorted out on this particular occasion.

I’ve just noticed that after a couple of minutes the laptop turns back of/goes into sleep mode with no light on the power button.

Is this when on battery/adapter only power or both, such behaviour is often caused by a break in a MBs soldered circuit when the MB gets hot and expands thus breaking the connection in the soldered circuit.

Could this be a hard drive failure? Ive never had that happen so I’m not sure what that looks like.Or would hard resetting the bios be a fix?

If it were a HDD issue you would still get the BIOS options as they are stored on the MBs BIOS chip + you would also get a boot error message on the screen.

By hard resetting the BIOS do you mean by pulling the CMOS battery, it is not likely to help but no harm in trying, looks like you need to remove the keyboard to do so though.

I’ve tried just the battery, then just the adapter, then both, it turned on every time. Im not quite sure what to try next. And i have to research how to take out the keyboard carefully. I’ll try any suggestions at this point if it doesn’t require buying a new motherboard.
Does my laptop have a magnetic on and off switch, could that be broken? Would that cause this?

[phillpower2]

Easiest to do first, see if you can get a known good stick of RAM for testing purposes only, integrated graphics devices rely on system RAM to function and if the RAM is bad you will not get any display, based on that you have since told us that the computer shuts down after a few minutes this is a long shot but always like to be thorough.

[ajshn]

I only have the ones in my desktop, which I assume are not going to fit.
How would I find the magnetic on and off switch? Ive never bothered to own a laptop before this one so im really clueless.

[phillpower2]

Desktop RAM is not compatible with notebook motherboards.

Sorry but not with you, what magnetic switch are you referring to.

[ajshn]

The switch that tells the laptop if the screen is lowered or open, if the laptop is shut or closed.

[phillpower2]

Thought that was what you meant but was confused as it has not been mentioned before.

Not all notebooks are the same but a common location is just in front left or right of the hinges on the base of the notebook.

Edit to add, some example pics here

[ajshn]

Thank you. By base you mean the top side with the keyboard?

[phillpower2]

Yes, back of the keypad.

You are welcome btw
