I made 3/4" x 2 1/2" strips of thin, doubled cardboard and then dropped them down into the slot on both the left side and the right side of the bottom left retaining screw. I solved the problem by removing all 6 display retaining screws once again and then shifting the display upward. From this there was no noticeable improvement, but on reassembly I realized that screen flicker would result from light tapping with the flat part of the plastic spudger under the display panel between the metal plate that retains the inverter board and the inverter board itself (essentially tapping a bit in the horizontal slot to the left of the bottom left display retaining screw). Next I shielded the display panel with aluminum foil on both sides to dissipate heat and then heated up the inverter board with a heat gun at 200✬, working one section at a time. The flickering problem showed 95% improvement. So, if the description of the problem I had in the original post seems to match yours, it is likely the entire screen that needs to be replaced :-( Wish I could say it was just the cable.but replacing it didn't help in my case.Īfter disassembly I cleaned the contacts of the LVDS cable with a gummy pencil eraser on the logic board side and on the display side.
The repair was somewhat difficult.the biggest hazard being removing the glass screen without breaking it. I've had the new screen for over a year now and can't tell any difference from the original screen.

The screen itself was $110, plus the heat gun and new adhesive to put the glass back on ended up being about $150. Long story short, I followed the ifixit guide to remove the glass, replaced the LCD screen with the one from ebay, it it works fine now.

I ended up buying a new LCD screen on ebay (LG LP133WX3 TL A2 A4 MACBOOK PRO 13.3" LED LCD was what it was listed as). I tried switching out the just cable with someone else's cable who had the same computer, but no luck. Hey all.this is the guy who started this post back in May 2010. Any tips would be incredibly appreciated.I'm in the middle of exams, and this is not making studying very easy! Now restarting, jostling, shaking, etc has no effect.Īny ideas? I suppose I'll do a little exploratory surgery today and see if I can re-seat any ribbons/cables that go to the screen.I'm hoping I don't have to replace the whole thing. Oddly enough, for the first few hours it would go away if I restarted the computer, but would reappear if I adjusted the tilt of the screen. Of note, the left edge of the strip starts exactly at the midline of the screen and extends 3.5 cm to the right -> I'm hoping this might indicate it's a loose cable responsible for carrying the signal to that specific real estate of the screen. There wasn't any associated drop or other damage to the computer that preceded this. I know this is an old machine and has probably run its time, but it still works great, especially I upgraded its battery & SSD about 2 months back (I already had upgraded the RAM to 8 GB & from HDD to SSD some 5 years back but SSD was only 130GB, and I added another SSD 250GB, 2 months back).I have an aluminum 13' MacBook (A1278) which all of a sudden developed a 1.5' wide vertical inverted, flickering, and interlaced strip running uniformly down the screen. I'm yet to plug onto another display (as I'd need an adapter for mini DP to HDMI) and I'd be updating once I do that. On Safari, the display is still blotted but much better than Firefox and that's where I'm currently using the Mac. To give some details, the issue is across apps, screens although it's most observable on Firefox and even after turning its hardware acceleration off from its preferences, it's no better. I tried several things (after looking up on YouTube) but none worked (resetting SMC, NVRAM, reinstalling OS, restoring from Time Machine).
All of a sudden a day back I noticed the screen started flickering and it's very difficult to make out stuff on the screen. I tried these but it seems like there is some hardware issue (I need to confirm this) Please note: this is applicable for Macs with non-removable batteries only. Press & hold Power + Option + Control + Shift for about 20 seconds.

Your Mac will go off and you can release the keys once it does (once you hear the startup sound). Try resetting your NVRAM: Shut down and while pressing and holding Command + Option + P + R keys restart the Mac.I would like to detail out the steps I took to try to identify & rectify the issue. You should give details of your Mac (yr, make, OS) and steps you took to fix it. I'm having the same (or similar) problem.
