I don't know the answer to your question. I am sure the programming experts here will have a much more detailed information for you.

Are you bring all the Insteon devices from the old home to the new home or all new Insteon devices? If everything is new. None of the ISY backup data may apply to all new devices.

I would also say remotely possible for a PLM to only stop processing X10 messages. It does sound like you have X10 signal issues. The 220 volt X10 modules are even more touchy. As in certain installations. Many X10 controllers have a stronger output as pointed out. So the controller may have enough signal strength to reach the X10 module and the PLM's output may not be strong enough. Have you tried the controller in the same outlet as the PLM? Do you have any X10 coupler between the two incoming power lines? Have you tried disconnecting electronic devises that maybe causing noise or signal absorption?

I have the X10 module but never used it. So no X10 modules are in the Device Tree.

I also know my X10 commands to Insteon Modules do not register in my ISY994i. As any changes. It just thinks the modules are in the last state it knows about.

If you have the Pro version. You can turn Off Automatic Writes to Battery devices. Then do one at a time. If the PLM is less than two years old. Smarthome owes you a warranty replacement.

I too have seen leads trimmed back to far and either falling out of the PCB or barely catching any solder to the pad.

I believe I had posted this in one of your other FilterLinc threads. http://home.comcast.net/~gafield/family/gary/electronics/X10_Filter.pdf One difference with the one I recently purchased. L1 and L2 are now one less turn but more tightly wound together. Probably the same or very close inductance as the older ones. I have also seen heavy conductors {like your L1 and L2} have poor solder joints or slowly fatigue and crack over time.

Great find. You did indeed get a bargain. If C1, C2 or C3 where open. The AC would still pass through L1 and L2 the heavy coils. FilterLinc would not be tuned correctly. If C1 or C2 where shorted. They are in parallel with L1 or L2. Again AC should pass through them. FilterLinc would not be tuned correctly. C3 if it was shorted. You most likely would have a big blown out capacitor as it is directly across the Line to Neutral. Between the junction of L1 and L2. I doubt the 10 amp input fuse would beat the cap blowing off the board. C3 is also the one that holds the surprise charge you sometimes experience when you unplug it with no load. A high resistance resistor across C3. Would have cured the stored charge syndrome.

Don't count on the AF120 being available in the future. Act is discontinuing all their A10/X10 products. The AF120 is on the list of some still in stock. http://www.act-solutions.com/

When you replace your PLM. There are exact steps to follow. Power down the ISY controller and PLM. Connect the serial cable from the ISY controller to the new PLM. Power Up the new PLM first and let it initialize. Then power up the iSY controller. So it will find the new PLM at power up. Use the Restore Modem (PLM) choice. To have the new PLM's ID written into all of your Insteon devices. If you have the Pro version you can delay writes to battery operated modules and then do each one individually.

Having the PLM connected on the same circuit as the computing equipment. Frequently causes problems. Unless the computing equipment is on a FilterLinc or similar filter.

If it is about two years or older. That is about when they start going bad. Mine died three months after the two year warranty expired. http://forum.universal-devices.com/topic/13866-repair-of-2413s-plm-when-the-power-supply-fails/ I would also say get a new one. They are reported to have updated capacitors in them. That should be better. If Stu's suggestion of cycling the power starts it going again. It is most likely close to total failure. I got mine through Amazon.

The PLM is not on the same circuit as your computing equipment? Computing equipment and UPS units are typical noise makers or signal absorbers. For Insteon power line signals I use a FilterLinc on mine. PLM in the front unfiltered pass through outlet and the UPS with computing equipment. On the filtered outlet.

It should but with one caution. The Insteon RF signal from the Range Extender. Has to reach one of the dual band devices you have installed presently.

Make sure the magnet is within normal sensing range of the sensor. You may want to GENTLY tap on the switch and see if it is intermittently changing state and verify the connections are tight on the IOLinc's connection block.

If the X10 controller is still being used. It is also possible it is also sending an X10 power line command and stepping on the X10 command from the ISY controller.

Have you had a chance yet. To try the X10 receiver you are using with the HR12. In the same place as the PLM? Is your PLM on the same circuit as the computing equipment, surge strip, UPS? Do you have any X10 Phase Couplers or X10 Coupler Repeaters between the incoming Lines? If so what type and model?

Restore PLM probably would not do much. Now when you get the new PLM make sure you follow the proper procedure or all of your Insteon devices will have the old PLM ID in them and not work correctly. Power down the ISY994i and PLM. Connect the new PLM to the ISY994i Power up the PLM. Power Up the ISY994i and let it fully boot. If you have the Pro version. You can turn off Automatic Writes to Battery Devices and then individually do them. Restore PLM to change all the Insteon Modules with the new PLM ID. 220 Volt X10 modules are a special case. You have to have the X10 signal on both incoming line wires. Depending on exact conditions it is possible the X10 signal is being coupled, out of phase, between the lines and canceling the signal between them. Jeff's tutorial on phase coupling. Page 8 touches on the 220 volt signal possibilities. http://jvde.us/x10/x10_couplers.pdf

The X10 cross reference sheet. Shows the Leviton 6371-1 and X10Pro can replace each other. Though the Leviton has InteliSense AGC for better operation in noisy environments. That the XPS2 may not have.

If you put the X10 Transceiver in the SAME outlet as the PLM. Does the HR12A Palm Pad still control the switch? The older model TM751 or RR501 Transceivers also have a stronger output than the 2413S PLM. So that also may cause differences. Depending on how old your transceivers are. Sometimes works and other times does not work. Sounds like you have an X10 power line signal issue. Since Insteon devices have a power line transmitter in them. They do absorb some power line signals. Insteon is passed along by the modules X10 is not. Some users have found as more Insteon devices are added. Insteon improves and X10 gets worse.

Have you tested with the X10 controller in the same location as the ISY994is PLM? That would see if you may have an X10 signal issue from the PLM's location to the 220V X10 switch.

You are welcome. I didn't do a 100% inspection of my 2.1. So it is possible other components may have been used.

If you have any 2443 Hardware 2 and above Access Points. Test them with the Communications Tests. I had two get flaky. One had a dim LED and the other would not send or receive in the Communications tests. Same Base PLM board with problem power supply caps is also used in the V2 Access Points. I rebuilt them and they are again 100%.

I see Lee Fleishman. On page one of the PLM repair thread. Reported opening a brand new hardware 1.C and it had the new C7 and C13. http://forum.universal-devices.com/topic/13866-repair-of-2413s-plm-when-the-power-supply-fails/
