Tip & How-To about Magnavox TB100MW9

Magnavox TB100MW9 DTV Converter repair

After a close-by lightning strike, my Magnavox TB100MW9
Digital TV Converter box stopped working. I took it apart and found a
shorted diode (the fat one on the power side of the board)
marked with the number SB340. From the NTE cross-reference
web site, I found a replacement diode, NTE586 (Si, Fast
Switching, Schottky Barrier Diode) that cost me $2.40 at
a local electronic parts store. I replaced the diode and
it works fine!
