I have an old Philips CM8533 RGB monitor that does work ok, however there is a noticable "hiss" and sometimes a smell from the top of the tube
So basically where the LOPT joins the tube at the rubber cap i think the rubber seal is not so good
I have removed it and cleaned the glass and inside of the rubber and re-seated it and it's better but still some "hiss" after a while
What i wanted to know is what can i do about this without the hassle of changing the LOPT?
I read somewhere that silicon sealant could be used as i guess it's just the rubber to glass that needs to be sealed
I have also seen on other monitors that there is some kind of reddish sealant around the rubber suction cap that stops it from moving at all, though a quick search hasn't found anything
Can anyone advise what can be done here?
