Need TM751 schematic diagram or a mainboard photo
« on: July 26, 2009, 09:43:50 PM »
Dear all,

Anyone have the main board schematic diagram of the tm751 or a photo of the board with the components? because the resistor that is above R11 and right D5 was burned and I cant determine its value.

Thanking in advance

A TM751 is so cheap (12.99 at both X10 and Automatic Outlet) that it's easier to get a new one than try to fix it.  I don't believe a schematic diagram or a mainboard photo exists.

Here is the TM751 main board schematic:

And the daughter board:

If anyone knows who created these, please add a post to credit their work.

Side note to Jeff's schematics.
The new TM751 with the RF daughter card from the CM15A; will not match. That daughter card can be found in the CM15A schematics downloadable from the FCC web site.
Not sure if the Main Board was also updated with surface mounted parts like other recent X10 updates.

Thank you for all your help, but my TM751 is the new version, with some smd components and not match exactly with Jeff's schematics, i will search at FCC website. Also I have others x10 new modules like appliances, lamps modules, switches... that not match exactly with the schematics found in the web.
