Hantarex Polo 25/28 Squealing
grantspain:
in the video it loses focus for a second, it could be related to crt socket
do you get same issue with no signal applied and raster obtained
perjmolsen:
Hi Grant :cheers:
When I have no signal applied (also test video is OFF at the adjustment board)
I get this on screen when i turn up the screen volts at the flyback
If I turn down screen volts at flyback I still have that strange sound, but no picture of course :)
Strange what causes that flickering and squealing sound....
I have looked at the pins and socet at the neckcard, they all look fine.
I am still thinking if it can be IC104??
I have some new ones.. so do you think it is worth trying to put in a socket and a new IC?
perjmolsen:
Hmm...
Not IC104... I have changed it still the same
princess prin prin:
It's one of the new flybacks that are available now. Why did you replace the old one? If you have an original one, try that.
perjmolsen:
Yes it is a new style one.
I just replaved it to see if it where the cause.
But it did not change anything.
I will put in the old one again.
