CRT monitor question - leak from rubber LOPT cap - how to solve?

Postby Chandler » Tue Mar 27, 2018 6:12 pm

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? :)

Hi there, the red sealant is probably a RED RTV Silicon sealant, try Googling Red RTV sealant, or try cpc.co.uk they have an extensive range of RTV sealants available. Made by Dow Corning. Leighton
