Vauxhall Omega Navigation LCD faulty

Hi Does anyone know of a repair facility / spares organisation that will help me repair my Sat Nav display LCD in my Vauxhall Omega cheaper than the 800 I'm being quoted by the offical dealer!
(The fault is that the screen is losing sync, but I belive its a bad connection on the LCD as you can press the protective dash perspex covering the whole dash assembly and sometimes the picture will return when pressing the perspex)
Details
vauxhall Omega Elite 2.5 Estate June 2000 final edition.
Siemans Sat Nav and radio
GM part number 09148316
Siemans Display unit part number 5WK70121
sub unit LCD = Sharp LQ5AW126
Thanks Pat

Try a laptop/notebook repair facility. Same technology. they'd probably be able to hook you up.
Failing that check a few breakers in your area or even out of London I'm sure that there's more than one Omega that's been written off and the parts are light enough to go through Royal mail without too hefty a charge.

If you try to fit a display from another Omega it needs the anti-theft protection de-activating before it can be removed from the donor car. If this is not done first it cannot be re-activated in your Omega.
BTW How difficult was to to remove the old display?

Hi Nick That's a blow! - probably means getting one from a scrap yard isn't an option!
It was comparatively easily to get the display off. Procedure. 1.undo two screws holding top half of steering wheel cowl on and remove the cowl . 2. remove the single screw holding dashboard assembly directly above the steering wheel. 3. remove the two ventilator grill 'inserts' to the left of the dashboard, by pointing them in the down position (grill vent pointing to the floor), then using a thin screwdriver, gently prize the sides whilst pulling forward the grill with snipe nose pliers (sounds harder than it is!) 4. remove two screws holding the ventilator grill housing and remove housing. 5. remove single screw at lower left of dashboard. You are now in a position to remove dashboard assembly 6. put the steering wheel in its lowest position to give maximum clearance 7. ease the whole dashboard assembly forward. (it helps to tease the right hand end out with a small screwdriver from behind the right hand grill - you also have to slightly push up the top cockpit upholstered cover, and ease the dashboard over the lower screw cover. Again - sounds worse than it is The pull on the dashboard needs to be straight towards you as the connection between the dashboard and the car is via a large fixed plug/socket (socket is part of dash assembly - plug is part of car body assembly.
8 Ease the dash board as far as you can to gain access to the two plugs on the left (rear) of the dash that connect to the display of the sat nav. Each plug has a retaining clip that is secured by a small 'proud' plastic pawl. The pawl has to be push in to allow the clip to be raised. This is the worst part of the whole job and is best done with a small mirror and torch and a thin screwdriver to prise the retaining clip over the pawl. once this is done with both clips - you can remove the dashboard assembly to the dining room table!
Sounds complicated but I can now do it in about 8 minutes!
Once the dash is on a bench, there are four screws and four plastic clips holding the metal satnav display unit into the dash.
9 once removed, four more screws (special heads) hold the top metal case cover on. remove them and you have access to the inner assembly comprising of 2 circuit boards connected together with two multi pin female / male sockets, and the third internal component, a tft screen manufactured by sharp. (this is the faulty bit in my case)
10 To remove the circuit board assembly, four more screws to remove, and a small two pin socket to take off. un solder a three pronged connector that is used to make a circuit to the three external buttons above the dash for clock adjustment (sounds dangerous bit isn't) and remove this connector assembly. finally remove a thin strip line connector from the rear of the circuit board by pulling forward the retaining clip by a few millimeters. The circuit board assembly can now be removed.
11 un clip the inner plastic retaining assembly to reveal free access to the tft screen assembly which can simply be removed.
total time from starting to remove dash to having a completely disassembled sat nav unit is about 30 minutes
But I still couldn't fix it!!!!!!!!!!!

Hi Pat
Thanks for the removal instructions, I've just dismantled and re-fitted mine. I wanted to see if I had the loom for the Sat Nav fitted but I don't so I'm going to give up on retro-fitting Sat Nat and get an add on device.
There's a new LCD screen for sale on Ebay's German site with the same part no as yours with 1 day left, might be worth a bid!

You'll need the theft protection activating once you've fitted it by a Vauxhall dealer but that shouldn't cost much.

Nick
