How do I fix the backlight of my garmin 3205

The LCD display contains both the display and backlight. They are integrated as one piece. Therefore the entire display needs to be replaced. The backlight connections are soldered to the LCD connections. Replace the entire display.

The display is dim and hard to see.

First, make sure that your brightness is turned up. You can access this from the menu by selecting "Display" then adjusting the display between 50% & 100%.

If the brightness is at 100% and the display is still dim, this is an indication that there is a problem with the backlight that lights up the LCD display from behind.

The backlight is integrated into the LCD display, so the entire display needs to be replaced. Was the unit dropped? If so, perhaps the LCD flex cable pulled out of the connector, slightly from one side, disconnecting the backlight. We strongly suggest that you don't try to repair the unit yourself. Additional damage can occur.

My Garmin nuvi 1300 brightness problems

I spoke to Garmin Support about this issue. There are 2 settings for contrast on the nuvi 1300. You need to set the contrast while it is plugged into the vehicle, and also while it is unplugged from the vehicle. The reason for the 2 settings is to save the charge of the battery while it is not plugged into the vehicle or power source.

GPS screen no longer lights up

If you can't control it with the controls, then most likely the backlight has died. The entire LCD display will need to be replaced as the backlight is integrated into the LCD display.

Tomtom 300

hello Simon,

Yes your'e right, the screen does have a bulb. Its reffered to as the ' backlight ' and from what you describe unfortunatly is sounds like yours has gone.
This light is somewhat integral to the screen so its more reasonable to change the whole screen rather than just the light.
There are other possible causes for the light not to be on as special circuits are employed to light up the screen. If these circuits are damaged in your device then its unlikely it will be economical to repair them.
I do hope this helps you or at least helps you to decide how to procede.
Good luck

Light is dimmed. Cannot make it brighter.

This happened to me, too, when I replaced the battery. Turns out one of the wires that affects the brightness came loose. I found the loose wire, touched it to a few places where I thought it should go, and one of them caused the screen to come on to full bright.

I was extremely nervous dealing with this - never soldered in such tight quarters before, but once I soldered it down, the problem was solved. I have other problems with my ique - like extremely limited battery life - but the brightness problem is solved.

TOMTOM GO 300 THe LCD screen won't light up.

Screens that don't light up are usually caused by the bulb going ( called " The Backlight " ). Unfortunatly , on a TomTom it is intergral with the screen so cannot be replaced seperatly. You can only replace the whole screen. There are other possiblities for the screen not lighting such as the ribbon cable that goes to the screen might not be quite plugged in right or theres a break in that ribbon cable + other reasons that become less likely as we go down the list. A simple test with a miltimeter by someone with knowledge of tomtoms will prove or disprove the backlight working and you should then know where you stand. Good luck.
