I would type in google each device and see if they take the same part number, or if you have the gps apart, look on the back of the screen, usually on the metal back plate, and it says the part number..but you would have to take the other one apart also to see..

Backlight burned out, how do I replace it?

The back light is typically an integral part of the LCD display, so you may have to replace the entire display. On some displays, the touchscreen and back light connections are separate from the display and on some displays, these connections are soldered to the LCD display. Trying to take apart the LCD display just to change the back light can result in breaking the LCD display. You are better off just replacing the entire display if you can find it for that model.

How to degausse gpsmap 172 gps

Hi Donnie,

Degaussing is not something that ever needs to be done on this device.

Degaussing is a term that I learned many years ago - it was a process performed periodically on early CRT (cathode ray tube) displays (such as a TV). Over time, CRT displays would build up magnetic charges that would cause the image to become distorted. A degaussing wand would be connected to an AC outlet and then brought very close to the display and gradually withdrawn. This would neutralize the magnetic charges on the display - and the resulting distortion. Years later, manufacturers incorporated a degaussing coil inside the display's cabinet that did the same job as the degaussing wand - thereby making the wand obsolete.

The GPSMap 172 has an LCD display that requires an electrical charge to create an image on the display. Unlike a traditional CRT type displays, an LCD (or LED for that matter) display is unaffected by magnets / magentism. Hold a magnet near a non-CRT type display to see for yourself. A magnet held near a CRT display however will distort the image more as it gets closer to the display. Caution: Doing this may cause PERMANENT damage to the CRT display. This is why many home theater speaker systems touted that fact that they were "magnetically shielded" so that they would not distort the images on the CRT display.

I hope this helps!

My unit back light is not working. the chart is displayed but can only be seen if you hold it to your face.

Backlights are part of the LCD display and consist of LED's. You may have to replace the entire LCD display or find another display that is cracked but has a working backlight. In most cases, you can swap backlights. There may be some soldering involved.

My Garmin GPSMAP 178C screen backlight failed

Backlight problem: Remove the display, remove the light tube from behind the LCD. Buy a led panel from Ebay for around $5 and install it behind the LCD under the drfusing layers. Run the wires out to a 12 VDC source and there you have it.

LCD Display is broken on my harmony SST-659

I wish there was a low cost solution to your broken display. However, the cost to repair will run more than a new remote.
I would recomend the Harmony 510 for a replacement.
Link below.

With many electroics these days, it is cheaper to replace than repair.
Good Luck
I hope this helps.
