Blank screen but working

Hail Ronda,

I saw u told the same thing as Apple on my post I found on the net and of course it doesn't do anything at all.

Those reset haven't solved many things on Mac...

I cut out pieces making it a bit larger than the square on the GPU and replacing the case is just not doing the thing since I always get nervous to take it out each time.

I got all the IFIX IT docs thanks. when I come here generally is cos I don't find the answer to solve my problem.

I'm not an expert but I open Macs for a long time now. I read many have difficulties to solve that issue and even Apple did a recall to the tech center for that matter few years ago.

I'll try to get that Scotch mounting square u're talking about and I'll let u know.

thanks for your feedback 😁

hey thanks for those info, yeah I tried to get something under the gpu without buying anything but it's not the solution cos it would work on pressing.

i too looked onto the Ifixit posts and it's as usual not easy since several things can be the problem

the screen is not completely black it tries to start light flashin!

I found very cheap inverters on ebay but i already got troubles to open the screen ahha the screws are too small..

supposed it's not the inverter since it's not black and then it has worked perfectly.

the display cable is expensive!

thanks I'll have to choose to buy the cable first

cheers

oh just took the memory off,replaced the battery and set it on the table .

the screen now has violet , black and grey lines!!! the light on the side of the opening button screen is lit like a sleeping computer!!!!

wow thanks so much for your support!!! man u're knowledgable about it ;P

I'll try that n keep u posted

regards

mac friend

Hey Ronda, I bought the inverter reed cable as u advised but it doesn't change a thing!!! the screen is blinking trying to start. SO I'll go for the first advice about the display inverter I should have bought first cos very hard to find compare to the reed cable which is easy to get new.

ps; maybe it's related but now the comp is opened without all the screws and aluminuim plates I realise as I thought the fan start up with the comp and stop straight away

keep u posted, finally I may pay the price my friend wanted to sell me the comp for to repare it if those parts are really the answer

thanks again

hey, replaced the Inverter display board received from IFIXIT.

dessassembling the screen is a nightmare and I destroyed one head screw of the clutch cover so I can't replace the cables into place... then now it seems cables are too long...

nothing has changed!!! the two changes haven't done anything the screen light up on the bottom or violet straight lines appears and desappear slowly to dark screen!!!

I think the screen is dead (samsung...)

I don't see what could it be! the inverter cable reed is new and the inverter board is tested as working from IFIXIT so I don't have a clue what's next as the HD is working fine and the problem comes from the screen only.

thanks for your help but at this point I don't think there is a need to waste more money this wasn't a good made from apple and I knew it since I already dessassembled a G4 Ibook and all the things I read about that comp. It's sad that apple sold these for expensive prices when it's all plastic sensitive light device.

don't think it's made for long life.

thanks my wallstreet and clamshell are perfect working order and although batteries don't last you can open them they still work

I'm desappointed I couldn't repair it

I got spear cables for nothing...

cheers

ahha yeah thanks, of course they don't come here for that stuff although back then in the early 2000 the support as been a forum of any stupid things that fortunetly apple cleaned up!

I just meant that this comp is known for troubles and what u told me should have fixed the problem since they aren't many replaceable device in that machine. Basically apart from cables and the screen you have one HD, CDdVD player and a tiny motherboard u can't even solder on it...

I don't think changing the small powercard would do anything cos I suggest there is a component that is tired since the comp works fine but I realized it's better with the powercord and the replaced non apple battery on together

anyway thanks, I'll keep on tryin moving cables incase one is defaulting.. the first time I got the box and the comp doesn't work lol

cheers

hey, I bought the cable to get an external screen but it's VGA strange from Apple who uses ADV n DVI! so I tried my 7220 powermac screen with tons of adaptaters but nothing's coming... I guess the whole screen part is dead hence the ship for that fontion...

when starting it I got some fun fast light white or blue... changing to the old cables n board back n forth.. I even think there could be a screen tired cable ...

who knows. but thanks anyway for your continued support.

I have a 2003 G4 to repair...hope I'll get luckier 😉
