Modem is off line. Comcast can't get it to

only they can fix there silly modem and system ! if dead. "my old" what does that mean>? that is only a CABLE ONLY model. from Comcast (theirs) that means NO ROUTER. < never run lacking one. buy one. SURFboard SB5101 DOCSIS 2.0 Cable Modem no wifi at all,there just one Ethernet port (sublan) best is add router (say netgear) to this this old modem and then let the router do its job and all IOT, all work. IOT is internet of THINGS. (all) test wired first then play with wifi, last, set it up. per the routers manual or ask buy a router first , own one, not old , new , new are safe. routers only not cable/router combo's like Netgear AC750 on up. R6020 like these (not docsis) the costs are based on speed. https://www.walmart.com/search?q=netgear&sort=price_low you must RTM , to set up any router. Read the manual. set SSID use WPA1/2 mode set in a wifi password, ( a good one, that is safe.) check out the new Netgear that have preset SSID. https://www.downloads.netgear.com/files/GDC/R6020/R6020_UM_EN.pdf I like where Netgear is going with that. pre assigned at the factory, and ready to run, no setup.. for noobs a big deal that. but your are not locked out of settings at all, PAGE 57

I need a circuit diagram for my Motorola SurfBoard SB5101

You can't see well enough to trace, but you want to perform detailed solder work, after burning out contact already? Perhaps it is time to purchase another unit...

My Motorola surfboard SB5101E is totally dark

Have you registered this modem with your cable service? Press the Standby button to reconnect Internet service. Check the coaxial cable at the modem and wall outlet. Check that the USB or Ethernet cable is attached at the modem and the computer. Try to reset the modem by unplugging the power cord from the modem and wait 1 to 2 minutes.
