Hello,
Thought I'd try and see if anyone here would have any idea of what could be the culprit of this type of horizontal shadows
showing up with white areas. Aside from this, the set is perfectly fine.
(MX4000 sw 4.7)

Grateful for any directions or ideas.

Usually the culprit is lack of proper isolation in video cables.

Thanks for the reply, kamiboy.

The dark streaking goes for menus in the tv as well even when not using AV.
It also has these bulging geometry issues, non-fixable with the service menu or adjustments to the yoke.

Maybe I'll just throw it away and get a good upscaler. Everyone's hoarded all the good monitors by now.

I am pretty satisfied with the MX4200 and Beovisio 1 B&O CRT’s that I own. I think they too exhibit something similar, but not to the same extent. The contrast andvor brightness settings might influence the severity of the effect. I guess it all comes down to how anal one is when it comes to picture quality.

You are right though in that most of the good CRT stock have already been hoarded by enthusiasts. Alas, CRT alternatives have problems of their own. Retro gaming is an exercise in choosing which cons one most prefers to have.

Hi Guys! Sorry to resurect an old thread but I just picked up an MX7000 for next to nothing but it wont currently switch on and I see no red standby light at all. It has a 2 pin Euro plug on the end of the cable which I have plugged into an adapter (I am in the UK so a 3 pin adapter) and the TV is rated for 240V AC.

I assume the fuse would be a good place to start, does anyone have any experiences of the MX range for things I could look out for?

I just got hold of a nice condition MX6000, had the back off to give it a clean and dust and adjust the focus. I’ve been through the service menus but other than using magnetic strips how can I adjust convergence on these sets?

It doesn’t have the options like my old BVM did. 8)

No you can't adjust convergence in any way. Even the static convergence (center of screen) is impossible because Philips tubes don't have adjustable rings on the neck. Convergence strips are never used on these tubes either. It's possible that the convergence while not perfect is within tolerance, i.e. it was like that from the beginning and was deemed OK at the CRT factory, and that you are picky about it due to your previous experience with the BVM. If you can't adjust to it I'd suggest you get a Sony PC monitor like CPD-E500E which costs next to nothing and allows to adjust convergence through OSD. Coupled with a OSSC should give a picture pretty much identical to that of a BVM with 15KHz sources.

Do anyone know if the LX2500 and LX2800 models supports NTSC/RGB through the SCART input?

Thanks for the in-depth reply and suggestion, it’s me just being picky to be fair. As much as I loved the BVM it was too perfect!
