Please help,no picture on my beloved 6 slot :(

hello all a sad day for me im gutted,in the last hour my hantarax monitor has just died on me,i have sound and can here the games starting fine,but alas no picture,if this is any help i noticed through the side of screen the copper ring was glowing bright orange good\bad i have no idea,any help at this time would be gratefully appreciated fellow neo fans.

"if this is any help i noticed through the side of screen the copper ring was glowing bright orange good\bad"

Those are the crt heaters, if they are glowing it means that this isnt a simple monitor power supply issue, the heater voltage is derived from the flyback transformer (on most monitors), so this indicates that the horizontal output stage is working. Sounds to me like you may have a frame collapse, no vertical scan, the brightness is reduced so that the vertical line does not cause damage to the crt phosphors (crt burn in).
To confirm this, turn up the screen voltage (bottom adjuster on the lfbt) this will show the frame collapse, if thats the case. If you are not aware of the safety issues dont mess with the monitor.

Some circuit diagrams and flow charts here.

thnaks for info,i cant get that link you posted up any ideas,if you could point me to the screen voltage (bottom adjuster on the lfbt) would be much appreciated.ps the glwing thing is a little bar which lies horizontal

Thats not the crt heaters , please email me a piccy of this little bar, perhaps a wire wound or cement resistor getting red hot- that changes the whole diagnosis..


the screen voltage is the bottom adjustment pot

PS that link seems to be down at the moment, try it later.

Thanks for the piccy glitch



forget what I said about crt heaters and screen voltage earlier, the component your talking about is a cement resisor (looks like around 20 watt)in the monitors power supply circuit, if thats glowing you have a short circuit maybe the horizontal output transistor or lfbt. Im suprised the mains input fuse has not blown. Its the sort of problem that maybe better checked out by your local friendly TV tech.
The pic you sent with the green label on the aluminium heatsink, I cant make out the model (there are wires in the way) what is that #.

ahh no sorry my mistake the little bar on picture above glows red,nothing on screen does at back,will check that label out tomorrow for you and get back to you thanks mate.PS no sighns of power on back of screen tried bottom pot made no difference
