Dell Inspirion 1545 backlight problem
A customer has cracked their screen on their laptop. Common issue, just swap it out and get a new screen however I’ve been having problems!
It’s a Dell inspirion 1545 with the new HD screen which has an LED backlight not your standard backlight. The unit has no inverted. After ordering up a new 15.6″ screen I went to replace, however I found out that it was not a standard screen. Anyway I’ve no ordered up the correct screen and installed into the laptop. However the backlight is not working. It as there is no inverter I can only guess the LED backlight get’s it’s power from the main board. Does anyone have any experience with this fault?
Just to confirm it was not the screen I ordered another, same problem, so I’ve purchased 3 screens and still can’t get the thing to work. The unit is under warranty however the customer told Dell they dropped it so I can’t even get dell to repair the mainboard now do’h!
I found a fix for this. I found on a forum that when the screen gets broken on the LED model of this laptop it has a small 3 amp fuse it blows. I cause me tons of trouble but I found a fix for it. if you remove the keyboard there is just under the video strap connecting and couple of circuit mount things that look like resisters. the first one is a 3 amp fuse. some actually are marked f1. if you look above the strap connecting it gives the specs for this fuse. I am not good enough to replace this fuse it is very small and I had to have a mag glass to see it. I just put a solder ball over it and it fixed it. Keep in mind it was there for a reason so this was my way to keep from throughing it away. I bought a new screen and cable and agrued with the venders over the condiction of these parts and got lucky and found a thread about this fuse. I have a small picture of the fuse but am not sure how to post it here so email me if you need it.
hey thanks Randy for the comment – this will help some folk out I’m sure. Have emailed you so I can get the pic and will post an update on my blog.
I just repaired one in my shop for 2 months by jumping the F1 itty bitty capacitor/fuse….anyway, it finally worked….i’m now in the market for broken 1545′s….cl
