BNR34 MFD screen repair


One of the first things I did after I picked up the GTR was fix the MFD's screen. The damage is usually due to the age and heat/cold cycles throughout their lifetime. See above photo - trust me when I say this photo DOES do it justice; it looked much worse up close from the drivers seat. You'll see what I mean below.

Before I get into things, please note this is not a comprehensive guide. I did this about 2 years ago and don't have many photos so I worked with what I could find. Feel free to comment if you require any assistance though and I'll be happy to help.

What you'll need:
- Scotch double sided tape (small roll)
- De-Solv-It (or something that can help to remove adhesive)
- A sharp flat blade
- Usual screwdrivers/sockets to remove the MFD from the car and disassemble
- Adhesive backed polarizing film - You can buy this from many sites including eBay. Make sure you get extra just in case.
- Something to squeeze out air bubbles from the film, a credit card or similar will work

Now here's a photo of the LCD once the MFD was disassembled:
What you are seeing is the badly cracked/damaged adhesive polarizing film. The yellow stuff around the edges is a soft rubbery-like glue. First remove the soft rubbery-like glue, this is quite easy and the De-Solv-It helps. Then start removing the old polarizing film by using a sharp flat blade to lift up the edge, peel very slowly until it all comes off. Mine broke into separate pieces due to the cracks everywhere. Keep at it and then use some De-Solv-It or similar to remove any leftover adhesive on the screen. Patience is the key during this, don't try to rush it as you may damage the LCD screen.

You should end up with this:

Next, cut a piece of polarizing film to the size of the black area of the screen, the edges don't have to be perfect as some of the screen will be covered by the plastic housing. Don't worry about placing it on the wrong way as only one side is adhesive. Once the film is seated properly you will need to squeeze out the air bubbles.

TIP: Leave the thin protective film on until after you've squeezed out all air bubbles, this will prevent nasty scratches from being left on the polarizing film.

Once you're happy with the film's placement, go ahead and stick some double sided tape on the housing in place of the rubbery-like glue you removed and re-assemble.

Here's what mine looked like once complete and installed:


The "light bleed" you can see is made more obvious in these photos. It's quite an old LCD so don't expect it to look like a screen you can buy nowadays. It will look like brand new out of the factory as long as you did the job correctly and your LCD isn't damaged.

If you are undertaking this job, good luck!

Apologies for the lack of photos, this was done quite a while ago and I hadn't planned on uploading a guide.
