Sounds to me that your replacement motherboard is bad. Where did you get it?

What I do when I replace dv6000 motherboards is lay the MB on the bench. Attach the CPU, heat sink, 1 RAM module, the power and switch.
Then I connect an external monitor, keyboard and mouse and I lay the hard drive in place and fire it up to make sure everything works before putting it all together.

I keep a spare power board on hand so I don't have to remove it.

Superior storage. Superior surveillance.

WD Purple drives are built for 24/7, always-on, high-definition security systems. With support for up to 8 hard drives and 32 cameras, WD Purple drives are optimized for surveillance.

Oh yeah, and I don't fool with used dv6000 MB's anymore. Good used ones are very rare.

This is the search I use to find new ones.

That sounds like another bad board to me as well. When will HP learn?

edbedb's suggestion about benchtesting the board before final installation is an excellent idea that can save you a lot of trouble and a lot of screwing/unscrewing. Just be that that the bench in question is in a static free environment as many times the damage static can cause is overplayed, but it is not something worth messing with as a risk factor.

After several attempts  of retrying  to boot  now I get  1 long beep and 2 short  but no display I even tried another set of new memory from another noteboook and have an external monitor attached.

The 1 long 2 short beeps mean there is an issue with the video. Which also explains why you're not getting output to an external monitor. Likely a broken connection or solder somewhere but the short version is unless you want to try and repair that board (which I don't recommend since we're not even sure it worked in the first place) you need another replacement.

At this point instead of throwing more money at a laptop with several obvious flaws maybe its time to consider upgrading and replacing it?
