How can I replace a Sony TV battery no longer in production?

I have a SONY Wireless LocationFree TV (1st generation) puchased in 2006. The battery no longer accepts a charge, thus the Wireless TV is no longer useable. The battery (BP-1XLa) is no longer available. Any way I can keep the TV out of the landfill? It is a great device; nothing on the market really replaces its function.

Sara Horowitz, just wondering if you can provide more info on the model (not just the battery). See if it has a LF or BP number somewhere.

Sure: the model number is LF-X1. I know it is a bit of a dinosaur, but it does (at least it did) well what no other device does, which was to easily and flawlessly enable portable TV-viewing. Over time, the touch-screen gave out and could not be callibrated, but we overcame that by controlling it with a SONY remote (from a different device). But just recently, the screen would not charge up and would not run on AC/power. So maybe it's not the battery but something in the connection to the AC charger. (The converter part of the charger heats up when plugged in, so I think that it is working.) Anyway, I've googled likely and unlikely sources for the battery pack and it's not to be found.

To clarify: the base station is LF-X1. The screen is LF-X1M.

Dinosaur or not, if it is doing its job, it deserve to be taken a look at ;-) There is absolutely nothing wrong, with trying to maintain older devices, I have plenty of those around. This is what ifixit is all about :-) let's see if we can find some solutions for you. Are you okay with using a multimeter, or know somebody that can help with that? You will have to measure the output of the AC adapter first, just to make sure that it supplies the proper voltage.

Thanks, o.t. It is from reading posts on fixit that I got the idea to control the monitor with a SONY remote after the touch screen function gave out, so I am grateful to the people who are so helpful with their ideas and knowledge on this site, and particularly to you for your thoughts on this.

There is, now, a new wrinkle -- a happy but unexplained turn of events. I brought in the monitor to a SONY repair for a repair estimate. They came back with a figure well over $250. Way too expensive, so I didn't authorize the repair, and instead took the monitor back home. I downloaded a schematic, thinking I would at least give it a a try at puzzling out what was wrong (and thank you for your suggestion to begin by measuring the AC output).

But here's what happened: I plugged in the AC adapter. The monitor powered on! Curious. I tried the remote. It worked. I tapped the screen. The touchscreen functions are back - and perfectly calibrated. I can't figure out what happened. A by-product of the SONY technician fiddling around with it it come up with an estimate? A cosmic gift from all the good energy flowing from fixit? Gratitude from an older device for my loyalty to it? I'm puzzled, but happy.

Woohoo, that is excellent. Sounds like a loose connection somewhere that just needed to get wiggled back in place. GREAT.....enjoy your Sony. Best of luck to you. :)

If you can find a battery of about the same size same voltage and the same chemistry (make sure of this!) you could probably solder it into to socket. Or you if it is a battery pack you could remove the casing from the pack and replace the individual cells (you can usually find cells of any size on ebay for a couple of dollars). Please note that messing with batteries is dangerous (lithium cells can catch fire). Also make sure you checked ebay for the proper battery for the unit. You would be amazed at what people have stocks of.

hope that helps

Thanks. It is a battery pack. I'm a literature prof so cells might be beyond my comfort zone, but it's worth a thought...
