sounds like that you might have an issue with your PSU, but before you go to the extreme, have you replaced your pram Battery? i know some imac g3 don't behave well if they have a dead or dying pram battery

@@imac7531 thanks for reply! Yes, I replaced the motherboard battery. I noticed that a transformer in the power supply is getting very hot, above 120 degrees, and I’m not sure if that’s normal. I thought about replacing the horizontal IC, but I don’t have the schematic for this computer. If you think of any other ideas, please let me know.

@@RaphaelBastosakaCoffnix i don't have a schematic sadly enough and i wish i did, i would love to share that info if i did, but 120 deg is very hot. i can see that interfering with the hardware. you could replace the component if you can fix it yourself or get a working one on ebay. i do have a few around here. But 120 Deg C? i can see that being an issue.

Sadly enough, bezel are extremely fragile and i don't have any that are in good condition to survive shipping. i do have screws and Screw caps and all for them. you can email me to : irecycleapplemac@gmail.com

Thank you. yes i did later on changed my Rams into the appropriate channels as it was pretty slow and laggy. One person in the MacPro forum on facebook saw the video and said the same thing as you did and i did change them around. it works way smoother now. i will see if i can make a short video on the Pram Battery swap. it is pretty easy without braking it. =)

Bios wasn't an issue on this end. the GPU was Faulty

it's actually the controller that is faulty. looking for a good working one is going to be very hard to find

Ya sadly enough, in this case, we conclude that it was the GPU. i took the machine apart and for sale for parts.

in this issue? mine was a bad GPU.

i did, but it was still a no go. no video output

ended up to be a Bad GPU. i still have the mobo, but i will do some practicing on reballing it

The GPU was gone, i still have the board and i'll see if i can find a donor and replace the Chip

i have replaced the paste on both GPU and CPU and the problem was still there.

I remember you. =) i'm very happy and glad the video helped. i have another project coming up soon on a custom tangerine ibook coming up. just gathering all the parts to rebuild one. and another Graphite rebuild "SE" as the case is not the greatest looking, so will be swapping all the parts in it's new body.

just hope this is allowed, but this where i got it from. www.technotronic-dimensions.com/Products2a.html

what was the last thing you did before it went black? do you have screen when you are in the bios or "POST"? try to press F12 several time when you boot, you should be able to get to the Bios setting. if you still have no visual, i am afraid that it could be something with bigger problems. it could be a component that failed, bad GPU, damaged data ribbon.

When it comes to the part number? it all varies on which brand you have. like LG, IBM, Samsung and HP. at the back of your LCD screen, you should see a big sticker like Samsung, the part number should be like "LT121SU-23" and LG ", "LP121SA" just an idea for you to look for when you take your screen off the Ibook. When it comes to buy? i would look on a used Apple parts website as there is a few out there, Ebay, Picclick, or if you are lucky, knowing the right person that collects them in your neighbourhood. Parts are getting harder to get lately, so if you can get a Part machine with a good working screen? it would be the best alternative. Even I am having a bit of a hard time getting some. ;) Hope this helps

@@imac7531 Thank you so much for your kind and thorough answer!!

Thank you =)

ya i spoke with Dell and the rest of the staff. we ran a lot of diagnostics and turned out to be a Bad GPU. i still have the machine and all, it will be on my list for a new GPU to be installed.

i have never had any issues by switching with another brand for as long as you swap it with the LCD original video ribbon cable. you can't use a LG ribbon on a Samsung lcd screen. but i have done many LCD swap from a busted Samsung to a working IBM, or LG etc and they all work very well.

@@imac7531 Ohh I see So Samsung and IBM are interchangeable/compatible with one another? Or is it like Samsung with Samsung, and IBM to IBM? I just bought an indigo Ibook g3 that will need an LCD replacement and I just wanna make sure i got all the facts right.

@@BluesLuxury they are all interchangeable for as long as you keep the original video ribbon cable attached to the screen. if you use per example a Samsung lcd with a HP ribbon? you will get a white screen or no image at all

@@imac7531 Thank you so much!! It makes sense now. Also any other advice or tips you think I should know?

@@BluesLuxury as of now, i never ran into any issues when it comes to swapping the screen. so if you have a samsung in your ibook? you can replace with a HP, or IBM or another Samsung.

Thank you 😁

Glad you like the video, i usually use plastic scratch remover compound, but first use ISO alcohol to thin out the paint, then use the the Scratch X remover. then if you want? you could also use a plastic polisher like i did at the end of this video to make the plastic nice again. And no, i'm not in France. i was from Quebec, Canada. moved in BC, Canada.

@@imac7531 thank you for your advice. And thanx again for the very interesting content.

Yes, same speed, same GTX 1070 graphics

@@imac7531 cool same with my laptop. sadly i had it repaired with a mobo problem...hopefully will be fixed soon

@@PestiLencE638 sadly enough, i found out that it is a GPU failure. i'm now selling it for parts.

i did connect the 240W adapter to the machine as i did forgot to connect it, but did connect it. as for the Cmos Battery? it was replaced by a new one. not shown in the video, but i did the process of a CMOS reset

i did another CMOS reset and still no change. =(

I may blame this on a very uncommon GPU failure of sorts.. Which graphics card does it have?

@@lukedavis436 it's got a GTX 1070 "BGA". after the CMOS reset, the screen had a lot of artifacts on the screen while i was booting on the usb drive. all went back to normal on the next reboot, but still black screen

@@imac7531 artifacting isn't a good sign but the GYX1070 was never known for failing. I'm baffled here

could be the wire or the power supply itself

lol, Thanks. it was actually fun doing it

Thank you Dave, will give it a shot. =)

sadly enough, even with the firmware updated, it still didn't fix the problem. found out that the laptop have a bad GPU.

You are very welcome. =)

i just hope this will help you, any Capacitor(s) that are bulging is for the lack of a better word "Failing" as it is no longer holding it's charge as it was meant to be. due to the age of the screen, those capacitors are known to fail. My best bet "in my experience" i would replace the bad capacitor(s) bad capacitor could cause the symptom that you are experiencing. Those CRT monitor don't actually have a 120 Volt plugged into the monitor as you know as it is powered by the graphics card so i will assume that the Cap you see that looks damaged might cause the issue for your CRT not working as it should. and the fact that the crt is not powered by a 120 volt? would be sensitive to any bad capacitor(s) or any other component that are failing or leaking.

@@imac7531 Thank you! I have currently opened the display, and removed the bad capacitor, will replace it and see if it works. It's such a beautiful piece in every detail, It's worth the trouble of repairing

@@rodrigocml i love those kind of monitor as it is pretty unique. the fact that it is ADC, but the clear case is what this little Gem more precious to the collection. i also have a 17" Blue and white CRT monitor from Apple that will soon be restored from the ground up as it has a bad Flyback. i was able to finally find a company that do sells them. i just can't wait to restore that monitor. Keep us posted on your progress. ;)

Will you post a video on the blue monitor as well? always loved those. I replaced the dead capacitor, but still no image on the display. I will need a bit more research on the matter. Good part is now I know how to disassemble and reassemble it

now with everything connected, the USB works, and I can hear a small Click sound when I give the display energy, but the screen won't start

very nice. i do have a few 600 around as i thought about upgrading that ruby into a 600mhz, but i think that would of been too much for it. those logic board will be saved for my next projects. :)

you have rotate them a little as they have kind of a groove. kind of hard to explain, i'll see if i can make a short video of it, but you have to flip the screen over of course, then rotate the base to match those little clip then pull it out. easier to do then saying it. there is also a big white O-ring it will come out once the base is off

i wasn't streaming today, just recorded today as i had some issues with OBS last week and trying to figure out why it kept crashing in the middle of a recording. it's all good :)

Thank you. :) Now looking for a 1.25 ghz logic board for the 17" imac g4 sunflower

yup, they are :) 😁

Found it. found it on my next video of the 400k floppy disk video. it was on the floor. :>

First, are you talking about the imac "Flat screen panel" or the Sunflower "with the neck that swivel"? iMac sunflower, you can swap motherboard from one machine to another without any problem, just make sure that the data port for your video signal is the same. if you are talking about the Flat screen panel "all in one" i wouldn't recommend swapping the logic board. But i will try this first before doing anything else. have you replaced the modem cable? might of been pinched or damaged. you did say swapped the modem from one machine to the next and the problem was still there. do you have a spare one around that you could perhaps test? is any of your cable behind a router or a switches? perhaps one of them could be bad if after replacing the cable and the modem "router" and you still have issues with that machine? i am afraid that the ethernet port might of been damaged by the storm. if you are comfortable with replacing the logic board, you could try to find another machine similar to the one you have and swap the board

@@imac7531 First, thank you for your advices. So im talking about the Imac Sunflower model. So i already swapped the modem and the cable from another Sunflower (whitch is 100% fonctionnal) and still dont work, so i guess is the modem/motherboard connection whitch is bad. So, the motherboard from the 15inch and the 17inch are identical, same data port, so will swap them. I was afraid to do this without knowing if this can destroy the machine... Thanks for your answer.

@@keomarty3863 Awesome for the iMac G4 sunflower. in that case, you should be ok on replacing the Logic board. they are pretty easy to swap around. just make sure that your video signal port are identical. i know in some of the ibook g3 data port are different, so make sure that they are all identical. Good luck and keep me posted. :D my next project is actually the imac Sunflower G4. i have no power on it and will be replacing the power supply on it. Hoping it is the power supply. =)
