I had to pull my F90 out to check some wires that may have come loose. While doing so, I put a scratch in the middle of the screen. It's not deep, but it is noticeable. In talking to a few people for suggestions, the best ideas were to use some very fine wet sandpaper and lightly (and with lots of water) sand across the scratch to remove the ridge of the scratch. The other idea is to use some jeweler's rouge (the kind to polish gold), and again, lightly rub across the scratch. Or will I need to replace the screen?

I've never heard of removing a scratch on a touch screen by sanding it.

Usually if you scratch a touch screen that's it over, it is expensive to repair and you'll need to take apart the whole unit.

My guess, if you sand it you will make it worse.

I agree, the resistive touch screen is VERY thin and not designed for sandpaper repair.

That doesn't seem like the most ideal tools around an electronic item

I don't think there's any DIY method to removing scratches off the screen, my best suggestion would be only if it's warrantied by pioneer, brick the unit by messing up a software mod, and send it in under warranty. If they ask what happened to the screen, simply say it came like that and it wasn't a big deal for you to call them about that.

Besides cleaning it first to see if that reduces the visibility of the scratch, using polishes will make your screen look frosty like a frozen beer cup.

I would send it in for service.

I've read a couple of suggestions online as I have an LCD TV with a small gouge.

#1 use a brand new, clean pencil eraser and rub the scratch lightly

#2 Fill the scratch with vaseline and it will make the scratch nearly invisible

I haven't tried either of these methods so they are at your own risk, but are cheap and probably worth a try.

Try Autoglym Glass Polish

If it works then get a screen protector for it as I have for mine.

Cheers

You guys should not be giving this advice! There is a Resistive Touchscreen Membrane on TOP of the glass LCD screen. The screen itself is most likely not scratched, just the membrane. Contact Pioneer about a replacement touchscreen overlay.

^^ I agree.

Just clean it first, then if not satisfied, send it in for service.

Perfect answer.

Not so perfect answer:

Sandpaper will make it hazy and dull. I don't recommend it.

Polish will give you an annoying shiny spot, probably worse looking than the scratch.

The resistive part of the membrane is on the inside, so chances are you could probably do either without hurting the function, but trust me, it will look worse than the scratch if you do.

The Vasoline trick might work to reduce appearance of the scratch, but would eventually wear off and will make your screen greasy.

There is nothing you can do to fix this yourself short of replacing the touch panel. They are usually attached to the LCD by very sticky clear double-sided tape on the edges. Obviously, replacing it will require disassembling the face.

I would just leave it alone or send it in to Pioneer.

1 Polyester Film

2 Upper Resistive Circuit Layer

3 Conductive ITO (Transparent Metal Coating)

4 Lower Resistive Circuit Layer

5 Insulating Dots

6 Glass/Acrylic Substrate

7 Touching the overlay surface causes the (2) Upper Resistive Circuit Layer to contact the (4) Lower Resistive Circuit Layer, producing a circuit switch from the activated area.

8 The touchscreen controller gets the alternating voltages between the (7) two circuit layers and converts them into the digital X and Y coordinates of the activated area.

Yeah, that diagram makes my point, resistive part is on the inside. The resistive part is 3. You could in theory, sand or polish all the way through layers 1 and partway through layer 2 before affecting function. Sanding or polishing will make it worse though, I can almost guarantee it.

Thanks for that. It also makes my point, so we both win yay!

If I may, Aviator, why not such a perfect answer? He gets a brand new unit that way, scratch free, and doesn't have to do any work about it.

If it's gonna be like that whole thing with Tacomaboy about "scamming an innocent person", then please, just agree to disagree and let the OP decide for himself (considering Pioneer is not an "innocent person"). If for any other reason, I'd like to hear it.

Well they might just fix the firmware and send the unit + scratch back.

That's a possibility, but it's also possible they may just ship him a new one. Just throwin out there as an option, since this screen is delicate and very technical.

if you go to this link and do not want to send it back you can replace it.

I may just bite the bullet and go this route. Thanks for the link and pics.

Everyone else: Thanks for all the info. While I knew the touch-screen was delicate, I didn't realize how intricate it is. This forum is great.

No...Pioneer is sure not perfect with this unit or the way they've handled it. But think about what you just suggested to the OP. To intentionally destroy a product to get a company to furnish you a new one for a problem you caused is fraud. Plain and simple. So much so that if it were an insurance company standing behind the warranty, they could easily pursue the matter. I'm sure you don't want the OP to risk trouble that way. Another exaggerated example...if your car had a problem that couldn't be fixed...even if it weren't your fault...and you decided to roll it off a cliff to get a new one...what do you think the outcome would be if they determined you did it on purpose? We all know the answer to that. It's the same thing only on a much larger scale.

Pioneer should stand behind their products. No doubt. They need to pay for their errors. But the consumer needs to pay for his own errors. No quid pro quo allowed...

That's not to say he may have a case to send the unit back and demand a refund for selling a defective unit. I could get behind that one. But that's a whole different other subject matter. Personally, from what I'm seeing done here, this unit may be one of the best units in the world with it's ability to be programmed for what you want. Just a few bugs Pioneer needs to fix we can't.
