Screen won't power on after battery replacement.

[Prizm85]

I replaced the laptop with genuine hp battery. First boot up had a cmos checksum error and then counted down, powered off. I tried turning it on and everything is running, I can hear it but the lcd is off.  I tried:

Using the old battery

Reseating the ram

Trying 1 ram at a time

Using only the power cord, no battery

Taking out the battery and unplugging, holding in the power button to drain power then letting sit overnight

Hooking up to external monitor (no luck)

Holding down windows key and B key at boot to try to get to bios

No matter what I try, the screen won't turn on. It worked after I changed the battery but after the cmos checksum error and the shutdown after it counted down, no screen. But I hear the other stuff running.

CAPS lock blink code: 3 short, 5 long blinks.

Any help is appreciated. Thanks! I've been working on this for days!!
