Hi,
 
This sounds like a combination of things. First of all, the minimum brightness sounds like your backlight is no longer functional.
 
The black screen but signs of the unit being powered on would typically indicate your LCD panel is knackered, supported by the fact the brightness went just shortly before.
 
The not powering on without a charger being plugged in is likely simply due to the battery being flat. As the screen isn't working, you can't see the battery indicator.
 
When a laptop's battery is flat, it's common for it to power on automatically as soon as the charger is plugged in, both my laptops do this.
 
If you want to go down the LCD panel replacement route, I've had good experience getting replacements from AccuPart.co.uk, have used them dozens of times for LCD panels. The actual replacement process is pretty simple, especially as you've already cracked your laptop open once. Just be careful threading the cables, particularly the WiFi antennae, through the hinges correctly or you risk shearing them in half.
 
Your other symptoms are a little unusual though. The disk tray not working and the fan not working could be symptoms of a dead motherboard, as someone suggested, however as you're cracked your laptop open are you sure you fully inserted the CD tray back in and reconnected the CPU fan cable if you disconnected it? If you're sure, try googling your laptop model plus "hdd light blinking". If this is some sort of error code, you should get a hit for it. Failing that try googling your laptop model plus "error code lights" and see if you can get a list of error codes for your laptop.
