Anyway to fix my Dell inspiron 1420's screen?

post #1 of 5
Thread Starter 
One day i turned on my laptop and it flashed red,yellow, and green not all at same time but throughout the time it was on. I have no idea how to fix this because this is the first time i've encountered this. I have no idea what to search up on how to fix this so i recorded a short vid on how it looks like when its turned on.

That doesn't look good. That could be gpu related rather than a problem with the screen. One way to check is by hooking an external monitor up to it and see if it does the same thing. If it does then the screen isn't the problem.

Pretty sure that uses integrated graphics rather than discrete so if it's the gpu replacing the board will likely be the only option. You could try reseating heatsinks and replacing thermal paste and see if that does any good.

If you end up replacing the board I would look on ebay first and see if you can find your same laptop for dirt cheap. Many people sell broken laptops on ebay for parts and such.

Just try the following and let us know what happens with each of them


-Plugging into an external monitor
-Remove the battery and power cord, then press the power button for 5-10 seconds
-Try opening and closing the monitor when it's doing this ... watch to see if anything comes up on the screen.

The 1420s have a KNOWN defective nvidia card (if that's what yours has). I would make sure that the video card isn't defective.

Are you referring to the 8400m-8600m chips?

Yep 8400m GS, I am trying to resurrect one of those chips in an HP DV6780se, from my diagnosis, the VRAM contributed to the problem most likely more than the GPU itself.

I opened it up and touched all the connectors and it seems the monitor connection was loose or something. I detatched and reattached it and its all well now thanks everyone!
