Inspiron 1545 LED screen - no backlight?

[dmagic17]

I replaced my LED screen on my 1545 with battery in and neither screen works at all now. Not even a monochrome picture with no backlight - nothing. Would the same fix apply if my screens are completely blank now or could mine be a different issue?
Thanks

Look at screen with a power flashlight. You have to see a picture. if not there is another issue.

I have found a solution to this Problem for DELL STUDIO Laptops. (1535 MODEL). MY STUDIO MODEL DOES NOT USE AN LED SCREEN SO I FOUND NO F1 FUSE.

My backlight has failed. I still get a faint signal to the screen but it is dark.


I replaced the bulb. I also replaced the Inverter chip. This might fix your problem but it didn't fix mine.

I DID NOT FIND AN F1 FUSE on the STUDIO MODELS. I fused a different chip which was VISIBLY DAMAGED. Disasemble your laptop so the monitor cable is visible. The fuse is just below the monitor cable plug in. See Pics:






This beetle looking chip (six legs) was visibly damaged. I fused it with a soldering iron. It WORKED FOR ME> BUT I DO NOT RECOMMEND IT. LOTS OF SMOKE AND SPARKS AT FIRST. COMPUTER SHUT DOWN and I thought I lost my computer. I GOT LUCKY AND the Fused chip works. It was a last resort since I am traveling abroad and needed a solution fast.

Thank you to all who posted on here with a fix, I blew the fuse on my Granddaughters Inspiron 1545 changing the LED screen, thanks to you I managed to locate the fuse and replace it

I have a similar problem with a Dell Studio 1440.. Would anyone know where the fuse is in this model?? I can't find anything labeled F1 or similar on the main board.

Thanks

Just to confirm, I bridged the F1 fuse on a Dell Inspiron 1545 LED and the fix worked, thanks!

I have this same problem with a Dell Vostro 3750, does anyone know where the fuse if that i need to replace on this board and/or what it is labelled on the motherboard or where i may find it?

I have a Dell 1545. The fuse on the top of the mobo, by the moniter socket, is good. There was a mention of a fuse on the back that went out. Could a screenie posted of that fuse? Any other ideas. The computer works OK, boots up fine, it's just the back-light issue. Thanks.

Hi,

I am using Dell Inspiron N4010. I am facing the same issue of backlight failure. Before this I tried to find dead fuse on mother board but failed... but on the circuit board behind the screen I found two fuses F1 and F2. When testing with multimeter F1 fuse shows 0 ohm which I believe is working and F2 shows no change in reading.

Can it be blown fuse (F2) which is causing LED back light failure?

Please help..
