The ram and adapter(tested on 400mhz) are tested and work. Tried detaching the pram. The model is a 1ghz dvi tibook. Cant find a solution online.
Got a tip for us?

Tibook g4 turns on, fans and disc drive spin for a second and caps lock and white light under the display work but no chime or image

You can try a PMU reset. Take the battery out, unplug the Mac and then press and hold the power button down for about 3-5 seconds.
Put the Mac back on charger, put the battery back in and then try to power it on.
Quite frankly though, those are the classic symptoms of a dead logicboard.

On the TiBook, there's a manual reset button underneath the keyboard. See pic from iFixit below (with red arrow marking the button's location):
Give that button a press for a second or two. Then see if your TiBook will boot.

Is there a chime if you plug in headphones?
Does the HDD spin up? Or does the ODD make a little mechanical noise when you press power?
If you disconnect the HDD and/or the ODD, does it get any further?
It’s pretty likely a failed logic board. The 1Ghz model is notorious for cooking itself.
The 867 and 667 models run a lot cooler as a drop in board replacement (the 2nd fan won’t connect to a 667 board though), but the extended heatsink from the 1GHz model will aid in cooling things even further.

I get a solid beep with headphones and i dont have a hdd in the disc drive spins for a second (it worked while it had a cd inside)
Ram fixed it now i hear the chime but i still dont have image. Where do the speakers plug in?
If you shine a torch through the back of the Apple logo do you see anything on screen? If so then the backlight or inverter board has failed.
I would try taking off the bottom case and reseating all of the visible connections. The speaker plug is a 4 pin connector at the opposite side to the power input.
It is possible for the backlight inverter to fail (this is the board mounted on the optical drive assembly when you pop off the bottom case), but it is far more common that the backlight CCFL tube has either been damaged due to impact or just burnt out. Replacing the tube is possible but it’s quite a job. See my thread: Titanium Repair Thread (continued) for full details.

Nothing when i shine a light but when turned on lower two thirds/half of the screen have a square like pattern on them. Will it maybe work with dvi to hdmi adapter plugged into the port?

Try the external monitor, if it's booting but the screen is dead it should still output to another display.
I have no problems fixing my PB 1.67 DLSD, but it seems the TI G4 models are harder to fix even for simple things.
