I think part of the reason there aren't floods of replies to your post could be that after performing the repair yourself, you mention that you might have left a cable unplugged but do not mention that you have made any effort to resolve the issue by double checking your work and ensuring that everything is properly connected. That's going to be the best place to start. Also check your BIOS to make sure there isn't a "Halt On Keyboard error" selected or put the keyboard back on.
Thanks for your reply! I can't check bios if I can't turn on the laptop. Before I changed my LCD, the computer worked perfectly without keyboard, so I think it's not keyboard faulth..
I re-checked this and every cable is properly connected..:emotion-18:
The blue LED is not the processor, but the hard drive access light. This LED should not be on continuously, but blink when the drive is being accessed. Where did you get the new screen? Anything you buy from anyone but Dell has a good chance of being used or and/or faulty. Can you still use the external monitor? If not, you may have fried the system board during the repair.
I got new LCD from local repair store, which buys used computers, after sells them for parts, etc.. At the moment I cant use any monitor, because i can't get any power to laptop to boot it up. Before LCD change, i used external monitor, and it worked well. I removed HDD, and plugged AC adapter, still this light only turns on, no boot :emotion-6:

This is ESPECIALLY true if ANY of the following exist:
You performed the repair on an ungrounded surface (pretty much anything that isn't an ESD workstation)
You didn't ground yourself by tapping something conductive and grounded prior to installation
You weren't wearing a PLUGGED IN grounding wriststrap.
There are so many variables in your repair that it's difficult to identify what actually caused this fault. You can view the 1525 Setup Guide and follow the troubleshooting section found HERE. The SOLVING PROBLEMS section starts on page 26. The solid Power Light ...nothing else is a display problem according to this guide. Better run through your work again with a fine toothed comb. Particularly check the ZIF connectors and FFC/PFC ribbons. You'd be amazed how something so small can have such a huge impact on the final result of a repair!
Although ESD problems vary in severity by conditions, it is not uncommon to successfully perform an internal repair honoring only the most basic ESD precautions (like dishcharging to something grounded by touching it's case while it's plugged in)
