got a free laptop with video problem.

post #1 of 10
Thread Starter 
Got a free laptop today but it has a problem. Backlight seems to work for about 5-20seconds than it dies out. What I want to do, is simply connect it through the vga to another monitor to run it through its paces to make sure its worth it to buy a new screen for it. Any possibility to fix it without replacing the screen or any ideas in general?

Edit:I already took it apart and replaced tim just for kicks.

Did the issue occur before or after you took it apart?

I would try to replace the inverter first ( test it it you know how to use a multimeter ). Its usually a stick of gum ( or longer ) sized PCB above the keyboard.

Laptop model would be useful as well!

Inspirion e1505 is the model. I have access to a mm but have no idea where the board is. And yea, it did this before I took it apart lol.

Some times they cram the inverter in the monitor housing. I bet about 80% of all the problems with laptops screens I have seen have been fixed with a $5 purchase from ebay for an inverter.

Note that every instance where I have changed the flat pannel out I had to change the inverter as well...I don't even try to use the old one now days, though. They are so cheap that I don't think it worth the time to mess around with them.

The inverter is easy to spot. They look like this.

I wanna thank you first. 2nd, it did not work but i had no idea how easy it is to replace those. i took one off of a functioning inspiron E1501(same part # according to all websites) but it did not work. I am guessing its the backlight and everything i see says you need a clean room to do that so im just going to order a new screen. i found the part number when taking the bezel of the screen and its made by samsung, 15.3" glossy 1280x800 and i found them from $59 used but guarantied to work to $95 new on amazon. thanks for all the help!

Awesome, that's about what I found them for price-wise. Even if you need to put a little money into it, it was initially free right? Cant go wrong there.

Thanks for keeping it out of the dumps as best you can as well. I admire repair and reuse.
