Laptop screen not working

mthatcher206563 · Jan 2, 2015

Hello everyone,

I have a laptop that is about 5 years old, I changed the hdd in it to an ssd, not long after I did that the screen stopped working.

I have taken it apart to see if there is any loose wiring, I have also tried the power button trick as well and still nothing.

The other option I found is to re-flow the graphics chip inside my laptop, but i am wondering if there was any options other than this as I don't own a heat gun?

Any suggestions would be fantastic and thank you in advanced.

You should be able to determine whether it's the screen or the GPU by connecting an external display (monitor or TV) to the laptop. If you can do that and a picture is displayed, then the screen needs replaced. If no picture on an external display, then it's most likely the graphics adapter.

Should the problem be the graphics adapter, a reflow MIGHT work if the adapter is a soldered chip on the board. Since you don't have a heat gun, you can look into the baking method (there are guides for baking a motherboard all over) as a means for reflowing. However, if the problem is in fact the graphics adapter, and the picture is generated by the integrated GPU on the processor, you may be looking at needing to replace the CPU.

Laptops are hard to repair, instead of spending time and money, I think it is best to look for a new one.
You can try to hook the laptop up to an external monitor to see if your videocard is still working, and use it like a desktop until you get another one. If this doesn't work most likely you won't be able to repair it.

Thank you for your time and answers Prostar Computer and bootcher, I am really considering getting a new one but if I can fix this one cheap then it's a bit of a bonus, I have already taken it apart and it has its own GPU chip and also if I connect it to a monitor, nothing comes up on the screen, I will have a look at baking if I can't find a heat gun but if you or anyone else can think of any ideas I will be very appreciative.

The reflow is sort of your last resort to repair it, so it seems. Take every precaution if you do this! If you want to bring it to a shop that does reflows, they'll most likely use a heat gun, though I'm to understand that an actual professional reflow workstation is the best way to reflow specific parts of the board.

Good luck!
