laptop will not boot... no display

[major]

this one's a doozie...

either using the battery or power cord, when i power up the laptop the led's come on, the fan spins, the hd spins, but no beep and no display.

it started when the power cord plug in the back of the laptop got loose, so i opened it up and soldered it back in place - because you used to be able to slightly jiggle the cord and that would cause a power glitch and the stupid thing would power off (the battery is crap - doesn't hold a charge).

here's another gotcha. there's no brandname anywhere on this dumb thing. it was purchased back in the mid 90's, so it's slow but it gets the job i need it to do done. on the top behind the screen it says "notebook".... like you couldn't tell. on the bottom it has a label it says "notebook computer" and has a basic cdrom drive and a 4.3 gig hd. the battery model number is 5002d nimh. when i put it back together i made sure i reconnected everything. i still don't get any video when i plug it up to a regular crt monitor.

what i'm wondering is maybe i damaged the mother board when i soldered the plug back in? and if so, how do i find the manufacturer so i can purchase another mother board or can someone help me verify if it is the board. i'm not afraid to open it up and "get my hands dirty."

thanks in advance for any and all advice!!!

That old of a laptop, the motherboard, might cost you more then the laptop is worth, that is if you can find it.
I would take it back apart and double check everything, and look for a number on the board.

I agree with andy. I am guessing you shorted it or caused some other damage when you were working on it and even if you could find a mobo for it, it would be very difficult to install it properly. You can probably find a used notebook of the same vintage for about the same price as a mobo would cost....

thanks for your input, but i have an update....

i dunno if it was just that the board was too hot or what, but i disassembled it again and put it back together just make sure all connections were secure and now it works better than before.

I suspect then that you had a short that was caused by your earlier efforts and the redo fixed it.... Congrats on getting it working regardless...:)
