Hi,
Note: I do not have the schematic for this chassis.
I have a Magnavox TV ch 27B502 in the shop with a shorted Q503 HOT
# 610597. I checked the driver xfmr joints (history) and soldered them even
though they look ok. Checking Q500, horiz driver (# on device is BSN274).
Note: No NTE replacement. The markings on pcb indicate this device has
a Gate, Source, and Drain!!!!! I tested the device out of circuit as a
transistor, and as a FET. Both tests indicates this is defective. Can you
tell me if this is a FET?
Thanks in advance, Brad
Tip for your old computer (reduce discard pollution too):
If you can't sell your old computer, don't throw it away. Use it to backup
your software by transferring files/folders from your new computer or laptop
to it. I transferred my Windows folder and other stuff to my old computer
using "PC Link", which I downloaded from www.simtel.net (cool site).
