Title: Oregon 450 problems
Post by: Walkslots on June 27, 2013, 06:20:48
My GPS accuracy is anywhere from 3 (ideal) to 10 metres. Lately, it is always at the higher end whoch makes it very hard to find a micor in the woods. I recalibrated but that doesn't help. I don't even know if that is what recalibration is for but I did it anyways  :).  Also, my backlight is not working this morning. A first for me. Any ideas what I can do to correct that?

I believe you have to replace the LCD screen if the backlight is broken and from what I gather, finding an LDC screen for the 450 is not an easy task. There are some PC repair shops on Bank (that I know of) that replace backlights on PCs....not sure if they could fix your 450. I can give you a few telephones numbers if you want to try them....

Check if it's still in warranty, I think Raytech in Montreal, (, is the only Garmin Authorized repair depot in Canada.
Check with Garmin in case you need an authorization number.

Before all that though make sure it's not a low battery or user settings issue. You may have turned off the backlight by accident, touch screens are notorious for 'pocket dialing' different settings.

Re-calibration would be for the 3-axis compass.

A quick test would be to get together with someone else that has a 450 and see if you are getting similar accuracy results.

Although I have a different GPS with a different chipset, after I dropped it I thought the accuracy had gone off, so I met up with CocaColaCacher to do a check to see if mine had gone off, and it was close.

If it's not a battery or setting issue and it is broken, getting a new screen may cost as much as buying a new 450, now that they are being sold new for just under $200.

Thanks for the feedback. I replaced the battery with no change and I checked and the back light goes out after 30 seconds but I don't see anywhere else where it addresses whether the backlight is on or off. I even checked out the manual.

A month ago Walksabit offered to buy me a new GPS with some of his pool winnings so it looks like I should take him up on his offer. I've only had this one 3 years but I have dropped it many times. Maybe it is one time too many.

I don't know how similar the Oregon and Montana are, but I suspect they are close. On my Montana, if I press the power button briefly, a new window comes up with a slider bar to adjust the backlight/brightness. I know of no other way to make this screen come up other than briefly pressing the power button on the side of the unit. I stumbled on this by accident shortly after I bought my Montana, as there was no user manual shipped with the device. I would be surprised if you hadn't accidentally found this feature after three years if it is the same on the Oregon, but it is possible.
