Hi guys:
This is my first time. I have a CTX color monitor
that conked out. It's 14 inches, Model 1462ES, made in
Hong Kong, with FCC ID: DBL1562. Symptoms are:
1. normal operation if the video signal is not
applied yet. front panel LED lights to an orange
color.
2. once the video signal is sensed, audible sparking
occurs between ground and the terminal connected to
the white wire from the flyback transformer. it's
the wire that is connected to the insulated
rectangular-shaped enclosed plastic connector
attached to circular socket around the picture
tube . there are three wires coming from the
flyback x'former, (big red one)is the high-voltage
connected to the crt, then the white one just
described, then the small red one connected to one
of the pins on the picture tube socket. No display
or raster.
3. together with the sparking the front panel LED
becomes green in color but breathes in and out as
if the main power supply is severely loaded
("sucked of it's juice") as a result of the
sparking as described in symptom #2.
Is it the picture tube that's shorted, the flyback
trasformer, or something in the CRT board? By the way
the monitor uses the Philips M34EDC14X CRT.
thaks a lot.
