Question about Apple 15" PowerBook G4 Aluminum 1.67 GHz LCD Display (p/n 1002587) (661-3749 1002587) Mac Notebook
What should appear black appears red on my whole screen. When i slightly press on the back of the screen on a specific area (mid-upper left), the problem disappears. Any idea what the cause is and how i could fix it permanently ? thx!
Usually intermittent problems that appear or disappear when pressing the screen indicate that the screen needs to be replaced. As much as I would like to be able to tell you a quickfix that will solve the problem (other than putting in a distance piece that will uphold the pressure permantly). The reason is that the flexcable that leads the signals into the actual LCD panel came loose. It is not a solderable connection that on that can otherwise be repaired. I work for a <a rel='nofollow' href=http://www.portatronics.com>Laptop Repair NYC</a> and if a solution popped up for removing this problem without having to replace the screen, we'd be very interested.

Take off your lower two screws on the front of the screen with a very small allen wrench. then, CAREFULLY pry the back cover off. you'll see a ribbon connector with yellow (mine was anyway) tape holding it to the screen (more or less the area you were describing). try removing the tape and playing with the conector (with the compuer ON- it won't do anything bad. you can just retape it with something thin and strong. I used packing tape when I replaced my screen.

Does this happen when you adjust the screen angle as well? Has the computer ever been dropped? Have you connected an external monitor via the rear video out port to see if the video card sends the similar anomaly?
Keep me posted.

Not to step in on an argument but the output side of a laptop inverter can be up to 1.5KV.. (or 1500 Volts AC).. Milliamps in current generally but they can shock you.. (Wont curl your hair for the most part).. Just a wake up if you handle incorrectley. Am Waiting for a customer to spill liquids in one of the new Air units so I can take apart and get my fingers into.. (Or Drop or worse).. Weve repaired a few of the New Black/Macbooks/Video as well as the whites and repaired more than too many of the old G-4 Ibook problems.. Will keep an eye out on these Now Hot-box Intel Models.. Failures are Inevetible in my opinion.
