[QUOTE="haywire, post: 411232, member: 16474"] Pixel Repair (not 100% successful yet) Ok this is my DIY pixel repair steps...definitely not recommended as it is too dangerous for your instrument cluster..basically you're attacking your working (but annoyingly imperfect) instrument display with a hand drill. Not a pleasing experience. Ok here goes: This is the problem with the pixel display that needs fixing: [IMG]http://farm3.static.flickr.com/2732/4461443808_b0e7a9b897_o.jpg[/IMG] First take out the trim under the display (aluminium trim/wood trim, whatever - no photos sorry). Basically pry it out, its just been held by two steel bars. Then take out the display fascia (3 torx screws on top, 3 phillips where the trim was, take out the wiring for the lights): [IMG]http://farm5.static.flickr.com/4031/4460665379_e3cfe736c9_o.jpg[/IMG] Take the instrument cluster out (2 torx screws, then take out the wiring behind): [IMG]http://farm5.static.flickr.com/4005/4460665447_68d1ed9283_o.jpg[/IMG] Instrument cluster out: [IMG]http://farm5.static.flickr.com/4005/4460665497_f3ce284ef9_o.jpg[/IMG] Take the front bit out (too complicated to describe here, simple description from now on): [IMG]http://farm3.static.flickr.com/2725/4461444044_55e4352e09_o.jpg[/IMG] This is the SCARIEST part: Drilling! There's screws behind the display that need to be taken out to remove the LCD. Actually there's another way to access the screws behind that white bit, but involved taking out the needles on the front which will mess up the reading and need recalibration. This is to bypass that procedure. [IMG]http://farm3.static.flickr.com/2798/4461444092_7cd7b3280a_o.jpg[/IMG] This is the screw hidden behind that white bit (there's 4 of them, so 4 holes to drill): [IMG]http://farm5.static.flickr.com/4026/4461444194_cc1a1b283b_o.jpg[/IMG] There's one each behind the speed and RPM display: [IMG]http://farm3.static.flickr.com/2719/4461444554_f1a1978436_o.jpg[/IMG] After screws has been removed, take the LCD out, carefully detach the ribbon cable (which is the cause of the fault): [IMG]http://farm5.static.flickr.com/4052/4460665803_c2547401b6_o.jpg[/IMG] Clean these residuals on the LCD and on the board: [IMG]http://farm5.static.flickr.com/4031/4460665841_ef8a3c48ef_o.jpg[/IMG] [IMG]http://farm5.static.flickr.com/4018/4461444398_7ef82104fd_o.jpg[/IMG] New ribbon cable versus the old faulty one: [IMG]http://farm5.static.flickr.com/4025/4460665933_b70f732f4f_o.jpg[/IMG] This is the tricky bit - aligning the new ribbon cable to the LCD and the board (this is the trouble I had, its quite difficult to get it to align): [IMG]http://farm5.static.flickr.com/4013/4460665969_7c2613f5f2_o.jpg[/IMG] Put everything back together and test in the car - not good result - ribbon cable incorrectly aligned: [IMG]http://farm3.static.flickr.com/2772/4460665761_53126668e6_o.jpg[/IMG] After numerous times trying, this is my cluster now - not 100% perfect but that'll do for now - I'm tired of trying it.
