Question about Garmin GPS 12XL GPS Receiver

Open Question

I left my unit on board for all the winter and now the display shows horizontal lines blank and many informations are very difficult to be read.In addition there is no link to the autopilot. I opened the unit and found a green wire disconnected from (I suppose) a disk-like on the upper part which has yet a soldered wire: it seems a battery, isn't it? Is it possible to do something to repair,since other functions work well?Thanks in advance

SOURCE: Display

The problem is a physical one, not a software issue.
I assume some sort of loose connection(s) at the screen or failure in the hardware.
Have been reluctant to dis-assemble without advice/guidance from someone that has experienced and solved the problem.
Can not update software as no link cable comes with unit.
Recently attempted to construct one ( found directions online for home made version) but needed a different type of wire than I had available at the time. (cost to purchase one from Garmin prohibitive for my uses) I have repaired an unresponsive Dell Axim x5 screen by dis-assembling and placing tape over a burnt ribbon connector so I am not afraid to work on the unit provided some success is possible. Not knowledgeable enough to just look for something that might not be apparent to the untrained eye with the risk of damaging the unit further. The unit is usable just difficult to read.

SOURCE: white lines across screen

normally RCA"S are common with this problem. Some of them have a knob in the back the adjust the brightness. This will sometime get rid of the lines. I did it to my RCA and it worked like a charm.

SOURCE: Unit shut down

I have run into the same problem and it may be related to the WAAS (Wide Area Augmentation System) feature. Try disabling this feature (under MAIN MENU / Setup). I used this receiver overseas (Asia and Europe) last year for 35 days straight with no problems. During this time WAAS was disabled as none of these satellites are visible overseas. The problem occurred intermittently prior to the overseas trip, and has reoccurred after returning. I was running into the same problem this past weekend and noticed the screen blanking out (with the vertical line) shortly after differential corrections were applied to the GPS signals. I disabled the WAAS and let the receiver run for over an hour. The problem did not return. Hope this helps.

Toshiba 57LX177: Right side of screen darker than left

I am not sure...but I have the identical problem. I believe the vertical lines are caused by the inverter board and the darkness is caused by the one of the back lights that needs to be replaced. I am tearing my unit apart now and will find out.
