Re: graphics problem. need to re flaot graphics chip ?...

There is no such thing as refloating the graphics chip on a mac laptop. The video card is intergrated onto the logicboard. You should first connect an external display to the machine to see if its the display or video card. Once youve eliminated that, you can rule out whether its the video card, or the internal hard drive. If its happening when you boot the machine, and it freezes or locks up, its most likely the hard drive or a faulty OS. If the problem happens intermittenly or when the display is pulled forward or pushed back, it may also possibly be a severed LVDS cable in the display or where it connects to the video controller on the logicboard.

Keep me posted,

Your certified Apple technician.

Apply about 2 pennies height under the GPU should take care the problem. Reason, the graphic chip becomes loose.

Re: graphics problem. need to re flaot graphics chip ?...

Sorry, Fire Sine, de troof is strange.

The ATI video chip on the iBook Dual USB (12" and 14") is soldered to the logic board using ball grid array (BGA) technology. For whatever reason, this particular soldering job was prone to failure on MANY, MANY iBooks. Apple had a free-repair program running for a time, but this has ended.

MaxyMouse, I'd be surprised if your local Mac shop had the gear to do the resoldering in-house. There have been lots of amateur-level fixes suggestion, all purported to "re-flow" the solder balls involved. Very dicey.

The only fix that -I- have faith in is done by First Phase Technologies. The good news is that their approach is inexpensive, using professional-grade equipment. The bad news is that (a) they want your bare logic board, they do not do disassembly and reassembly, (b) their work is "best effort". I've had an iBook 800 processed by them, and it worked perfectly. In my mind, this is only worth doing if you have a 700+MHz G3, or a G4. Let me know if you want/need help with the teardown.

This is definitely a hardware problem and not a virus. Flashing red, green, and blue is a sure sign that there is something wrong with the graphics chip, as those are the colors each pixel is able to be. The graphics card is telling the screen to display those colors instead of splitting up each signal for each pixel. If you take it to an Apple store, they will be able to save all your data and simply fix your hardware.

My laptop screen is blank when it's turned on???

If you have tried pressing the brighten button at the top of keyboard, then you may need a new inverter board or new backlight. A new backlight is a to replace because it's soldered onto the screen and you have to take the screen apart to access it. That's why tech stores would rather just sell you a new screen. A new inverter board is relatively easy to replace depending on your skills and patience. If the above doesn't remedy your problem, then you have an issue with the graphics chip, which means replacing the entire mother board or removing the bad graphics chip and replacing it.

My MacBook Pro fails to start up. The display remains dark and the sleep mode indicator glows steadily. It does not chime up on startup and gray screen or logos are never seen.

There are several different possible causes so if you have your manual it will tell you how to go through some of the resets. From what your describing it sounds as if the graphics chip is one of those possibilities. Nvidia had some questionable chips used in some of the 2007 model MBP's so if your MBP falls in this category you need to call Apple as they extended the warranty for these models to 3 years. There are some home remedies for this issue but I would definitely go through Apple as the graphics chip is part of the logic board as a lot can go wrong and there is no graphics card to just change out. If this doesn't apply to you then your back to the resets which you can get a list for all of these on the Apple website.

You need a new screen or problem with your graphics chip. Take it in to the Apple store and have the Apple dorks deal with it if your under warranty.

My apple laptop will not boot up all the way. it will do the start up sound and then get no where. It will not even get to the screen where i can put in my password.

Check ATI graphics chip heat sink, remove the soft pad that is over the chip and contacts the metal heatsink and replace with a penny prior to 1983 for good copper content. The penny will transmit heat more effectively than pad to the heatsink and will also put tension ontop of the chip to make better contact into its own solder and it will hopefully reseat itself. the problem seems to be that the chip heats up so much that it actually lifts itself out of its surface mount solder connections and becomes disconnected and that means no video. Look up "Mac ATI reflow"

Sometimes my ibook display comes on sometimes not. If it does come on the computer freezes during boot up, if it does not come on the computer boots up ok but no display?

You have the famous GPU problem. The graphics processor has broken solder joints. You can repair the problem by reflowing the GPU chip or puttin a shim on it to put pressure. Here is an Macbook Repair Guide that shows how to open a Macbook. If you want somebody else to do it for you go to Macbook Repair.
