Quickie! Philips CM8833MKii Customer Repair! - Mullard Repairs

Ойын-сауық

Quick repair on this Philips CM8833 MKII Monitor, by Mullard Repairs!
Started off with slightly high G2 (A1) voltage, and off focus.
Customer asked me to give it a once over - and adapt for S-video!
Sorry for the crappy video - only a few mins long!
I run Mullard Repairs, based in South East London. If you’d like your vintage thing repaired, get in touch!!

    I have a mint boxed one of these in the loft which I need to put a new power switch on.

    These Philips rgb monitors are really nice. I have the previous model which I recently modded to take svideo.

    The MK1 types. Both work great. Only frustrating thing is with the MKIIs is lack of proper scart which makes wiring up anything quite difficult… I modified the RGB port to carry Y and chroma to go into a small Svideo adapter, rather than drilling holes in casework etc

    @@The_Studioworkshop The SCART in the MK1 can be a little troublesome as you know. I try and be as gentle as possible with the connector for that reason. I have not needed to reflow that yet. Mine has a minor fault in the shadow mask where there's an obvious single 'dead pixel', could be a a fault in the phosphor or just some dust but you can barely notice it. I'm glad I got in there last year and serviced the deflection yoke, caught some early signs of corrosion on some windings and taped up those problematic rubber spacers.

    Hi why do you put paint on the anode cap? This is not good practice. The only additional thing to use is silicon grease which some manufacturers used to provide an additional barrier to prevent tracking and therefore to stop the EHT leaking to earth.

    As an anti removal seal. Many manufacturers and engineers do this, I’ve seen it done personally on other repairs, and it means I can tell when someone has removed the EHT cap, if it comes back for repair. Anti tamper is really important, especially when you deal with the general public. Once someone tried bringing back another monitor… claiming it was the same… but serial numbers were different, but most importantly did not have my repair sticker, or dab of paint on one of the screws etc. Silicone dielectric is used to prevent flashover and form good connections… that has nothing to do with what I’m doing here 😂 No reason why it should be considered not good practice. It’s between the top silicone and the glass - not contacting with the conductive anode. I also use nail varnish for converging rings.
