My 2002 apple Emac’s display is not working the computer boots up and makes a chime sound. I have opened up the computer, the display cable is in tact and there does not appear to be any damage when booting the computer the display crackles.
Welcome!
It is always best to start your own thread rather than tagging on to one that is almost two month old. Your issue is with a newer model than the OP's and is a very different can of worms.
Still, I can see a potential issue in two things you wrote:
1) Mine is a Apple eMac G4/1.25 (USB 2.0) Spec.
2) ...keeps freezing a minute after the Apple logo...
That entire sub-family of eMacs is suspect due to widespread and fatal logic board issues. The point of freeze is also a classic symptom of a fatal problem.
Find your serial number by manually opening the optical drive door:
Then compare it to the list of serial number ranges in this listing:
Ironically, the eMac pictured above from Apple's archived article on eMac serial numbers is among the affected units.
⚠️ NOTE: Some affected units fall outside that range.
If yours is among that group, it is time to say goodbye. It has served years longer than most USB3 1.25ghz eMacs. Msot died young.
The video hardware cannot be replaced without a new logic board and, because so many boards were defective and replaced under warranty or by service technicians, the chances of finding one on the used/pulled part market that does not also have the Curse are dreadfully small.
Even if your eMac is not among those listed, a video hardware failure still needs a virtually unobtainable logic board.
I wish I had better news but the eMac was a very troubled series. I really liked them, but only the last variant, the 2005 USB2 with the 1.42GB processor, seemed defect-free.

The first-gen eMacs from their intro in April 2002 through about August-Sept 2002 had defective IVAD cables and the cables do not look "bad" when physically examined. It is an internal fault.
when booting the computer the display crackles.
That was a classic symptom of a bad IVAD cable.
I suggest it is time to let the eMac go. Only that last models, the 2005 1.42ghz were largely trouble-free.
Replacement cables are available but only a profession TV repair shop with CRT safety measures in place should attempt to work on such issues. Labor costs alone are can be several times the value of a 19-year old computer that cannot run the latest software. Also, the case is easily damaged on reassembly. The average TV repair shop will not know this.
I've also heard that some shops are no longer service CRT devices.
Did I mention that the residual voltage in a CRT computer can kill?
I have one also but keeps freezing a minute after the apple logo and the screen is white with 2 thick vertical black lines (Always comes up but not always the same sort of 2 vertical lines). When I checked hardware test it came back with bad video ram however sometimes it passes also. Is the ATI 9200 Radeon is soldered onto Mainboard?. Just checking that there is no easy option to swap out video cards for an eMac. Mine is a Apple eMac G4/1.25 (USB 2.0) Spec. Any help would be appreciated.
Thank you for you very informative response. Being very new and first message on here my apologies for not following protocol.
Again thank you for confirming what I suspected and best to say goodbye and offer it as a part machines at best. Thanks again.
Hey! No need apologize about posting here. There are far too many other forums where starting a new thread will get you flamed. That's just rude of them. A new thread here works best because you get full help with your issue without diluting the help the original poster deserves. Also, most of us senior contributors are older than dirt and are easily confused!
What were we talking about??? 😉
I hope you continue to participate regardless of what Mac you end up owning!
I support your decision. I am a fanatic about keeping old Macs working but have encountered several eMacs with your very symptoms and simply could not find the parts needed to resurrect them.
See ya!
