Question about Samsung TXN3245FP 32" TV
To determine the cause, you might have to take out
the Horizontal Output Transistor.
There can be two points , where you can check
the Supply B+ to your Flyback
a ) Direct measurement on the Collector terminal
pin on the PCB ( after you have extracted )
b ) Direct measurement on the 200V line and post
Next after noting it down,
You will need to unplugged the yoke
You will also measure the voltages later
When you reinstall a new one ( But do not , yet
till I know the B+ you are having )
when these is connected and unconnected,
These is it for a while , while I would be suggesting
more, after I have known the B+ that your
Flyback is having.
These are your possible causes:
a ) capacitor parallel to the Horizontal Out Transistor
b ) bad yoke
c ) partially shorted Flyback
d ) fake Horizontal Output transistor
e ) Over driven Horizontal output due to
HDT and onwards to the osc.
( from the jungle IC )
f ) High B+
h ) High Voltage has exceeded its limit.
