standby light glowing but not starting up

Hello All
My macbook pro 2006 was running way too hot. I followed the ifixit guides to open the laptop, to find huge amount of dust (dust balls!) covering the motherboard, and the exhaust fins of the fan.
I did not disassamble the heat sink, but removed board, fans and superdrive. I dusted with parts with a small brush.
When I started up the machine, i could hear the superdrive starting up, and the fans revving up. But the standby/sleep light glows (constantly, not pulsating) and the screen is blank. I had left it for half an hour, and nothing changed. I also reset the PRAM (holding power button with battery and power supply disconnected for 5-10 secs)
I opened it again, and lifted the keyboard assembly (without disconnecting it) to check. The fans are working fine, but the machine is not booting up.
I also see a thick black line (isight wire?) running across the apple logo on the back of the LCD. the apple logo is not glowing.
Could you guys suggest me some diagnostics/possible source or errors? Any help is deeply appreciated.
Best
