XM 2000 lcd screen

I have a XM 2000 handheld vhf marine transceiver. I works beautifully but as the battery goes down so the LCD screen gets dimmer till the point were it disappears but the radio is still working fine.
Can anybody suggest a fix or a company/person capable of repairing it, I dont want to replace a perfectly usable radio unless I have to.

I'm no expert on LCDs but when you say "battery goes down" are you talking a few mins before it goes flat, or a "slow death" throughout the day?

I ask because it may be that the logic in the radio is that the vox is the prime reason for having the radio, so keep that alive as long as possible at the expense of the "anciliary" stuff.

Either that or it's gubbed!

I take it you have proof positive it still TX/RX OK when the screen is dead? I ask because if you can't use it (change channel etc) because you can't see the screen it doesn't sound "perfectly useable" to me.

Worst case you replace it and carry it as a spare. If T/RX works and it's got enough charge to keep the screen alive for a few hours it will probably work fine as a backup set.

I was kind of thinking about this. The LCD screen is likely driven by 5 volts or less. Your power input is 12V. If the screen is dimming as input voltage decreases, that would imply that your power supply is not regulating (which I would assume it would have to in order to maintain a steady brightness.)

Assuming that is correct (and I'm not saying it is), I would be reticent at best to trust the rest the radio to work when you need it.

Just a thought;
