Tatung Monitor Won't Start
Titan91:
Ed, those schematics don't appear to match the chassis I have. Are you sure about them?
Titan91:
R102 and R114 check out. I'm going to test some other things around the power supply area. If a cap is leaky would it cause absolutely nothing to happen? Or would I see some form of activity for a split second before the watchdog circuit shuts down due to incorrect voltages? I don't have an ESR meter to test caps and we're not getting one. I do have a cap kit for this board but it seems to be missing various filter caps in the power supply section.
Titan91:
The transformer at T101 appears to be bad. I've tested all possible pairs on both sides and I either get open or short, no normal high resistance readings. Also no connections across the core so there don't appear to be any windings going across. However, some of these pins are shared on the primary side anyway and I'm not sure if I'm drawing the correct conclusion because I can't find anything about this part on the Internet. It's a T60001AA LTE.
Titan91:
The board also has some jumpers run, probably from previous troubleshooting. Are these jumps correct?
ed12:
jumper's on a monitor board are not un-common
as mfg's will tailor there board's to suite a coustmers need's
and or do mod's to remove part's
second u cannot propley test a transformer without a :ring: tester
and knowing what impedace and inductance to expect
with a ohm reading u are olny going by a gut feeling,and or an open
or a dead short from primary to secondary
but in line windings such as pin 1 to 4 let's say should read as a common
and a low ohm's
