How do I fix the backlight of my garmin 3205

The unit powers on and works but the display is very dimmed and does not get bright even after raising the brightness all the way. The unit is no longer sopported by garmin so I can not get spare parts from them. Any help would be greatly appreciated.

    You take it apart, split the LCD display and remove the mini-fluorescent tube, measure it and order one from CCFL Warehouse

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.

Hi,my garmin gps device have this problem: I power on the device and after a few minutes,the gps turn off,just shut down. This is a configuration problem or something else.

Hello,

If the unit completely turns off than there is an issue with it, if the screen dims but the unit is still running it may be in your display settings that you have it to automatically dim backlight to save power.

Hope this helps!

Front display poising backlight and goes dim.

I believe this is most likely due to incorrect voltages at the display. If you have a meter and are familiar with working on electronics, check the voltage at pin 3 of cn501. It should be -28.5. If the voltage is very low, try changing C123 and C124 in the power supply. If the voltage is ok, check R925 and R932, these are both 10 ohm 1/8th watt.

Dark Screen even when i adjust the 'brightness' tab?

check the power settings on te unit, if it is set to default for the backlight, possible that your LCD's backlight is not powering up properly on the unit or LCD's backlight needs replacement.

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.

Dim Screen when Power is Unpluged

If you see a very dim image or black screen or flicking image on the LCD screen it means you have a backlight problem.

Connect an external monitor to your laptop and power it up, if you see the normal Windows images then the video card and laptop is OK and the problem is definitely the backlight.

Dim image and/or dark display on the laptop's LCD screen indicates a faulty LCD backlight and it could be the inverter that supplies high voltage to the CCFL lamp or it is the CCLF lamp is nearly burnt out or burnt out, most likely this is the case.
The inverter can be replaced easily but the CCLF lamp is more time consuming and requires soldering skills.

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.
