Some days ago I brought home my parent's old MX4500. It had been sitting in their garage for some weeks. It had developed quite soft pictures so my parents bought a Phillips LCD instead. That left me with a MX4500. When I got it home and plugged it in and turned it on, it went bang, I opened it and there was a large spark right beside what I thing is the high voltage parts in the main board. A piece of plastic stopped that short-cut, and now the TV can turn on, but the screen is blue or white all the time and all sorts of tiny sparks is developing at the end of the picture tube (electron gun) and it startet to smell a bit odd.

So, what to do... I am to sentimental to bin the set, but on the other hand a used and working MX6000 can be picked up for around £200 here in Denmark so spending money to repair a 20 years old tv is probably not the best idea. Am I overlooking some solutions here? Does anyone have a fix to the problems of my MX?

Any help is much appreciated.

best regards

aha, unfortunately I am not that technital, where will I find the ground cable? from where does it run and where on the chassi should it connect?

thanks

Christian

Thanks. The metal wire seems to run in a V-shape, connected to the metal frame by a hook in on end and by a spring in the other end. I do not see a wire, besides the one running from the metal wire to the end of the picture tube, am I overlooking a wire? It could be something had come loose during the car ride. Still lots of sparks at the solderings on the boards on the end of the picture tube.

What a nice straight-forward, informative and helpful post!
Even I followed it and I am not technicaly minded.

Hej Christian

Skriver lige på dansk det jeg bedst til, jeg vil ikke anbefalde dig og begynde og lave en MX4500 eller MX5000. for det første er det ikke et B&O tv men SHARP og alle dem jeg har set. de sidste par år er slidt ned... Når man har reparet en fejl er der kommet to ny, fordi printene er så møre, efter 20 års brug. hvis det er et pænt tv ville jeg købe en grim mx6000 også flytte de udvendige dele over. MX5500 og op efter er gode B&O tv som de selv har lavet elektroniken i. meget bedre i sidste ende også har du to skart stik og link mulighed, MS og LS er også gode bare uden link og kun et skart stik. sidst er der ME og LE som er med philips indmad så heller ikke lige min kop te :)

I am truly overwhelmed by all your enthusiasm, suggestions and sympathy, many thanks to both bang1, ipaul and the rest of you guys!

As I am not wizard with a soldering iron, perhaps I will get a friend of mine (an electrician) to replace the 10 ohm resistor and see if that changes the matter. Under all circumstances, I will keep the beauty; at least as a sculpture (although SWMBO is not very happy, but then I introduced her to the idea of a used Avant 28 inch, and then the MX/LX solution apparently was the latter of two evils…). Hopefully I can lay my hands on a whiteline LX2802 that one of my colleagues is not using at the moment.

Bang1’s idea of using the external parts on a MX6000 is not a bad one, I have thought if that myself. But as a used Avant is the same price as a used MX6000, the Avant solution is tempting.

By the way, as I got a Beocenter 9000, I suppose I could use the MX4500 as a link speaker (connected by a datalink-cable) with the picture tube turned off, what combination on a BL1000 would turn on the radio via the speakers of the MX4500?

Thanks once again!

Problem solved, just bought a used MX6000 with new BL 1000 for the sum of £200, more will follow, i am wery happy now...

Chr.

Just the way to go

Actually, I was just going to buy an almost new BL 1000 for £35, that a private person had for sale in the area where I live. But when I showed up it turned out that he also had a mx6000 for sale for about  £140. So I took the offer, and arranged him to drive the television home to me in his BMW 540 (nice car). The MX6000 is from 1994, so I suppose it is an mk1, but does anyone know? The software version is 1.1.

I have hooked it up to my ouverture via a standard din cable and the aux-port of the ouverture, works just fine so I do not see any reason to buy the 1614 converter.

The MX6000 is black, while my faulty mx4500 is white. I am going to keep the mx4500 for spares, and then I can always change the cabinet of the mx6000 into white if a whish. The picture of the mx6000 is just spot on, and the sound is brilliant, can’t see how the mx700 can be that much better but I have never really compared them in test.

best regards

Well there are no resent to find out before you come across a cheap MX7000

Give me the type number then I can tell you what it is

I suppose the sound of the MX 6000 could need some 'clarity ', and the bass responce could be better, but hey, it is miles away from my old 28'' Nokia TV. The MX7000 probably got a better bassresponce as it got active speakers. But the actual speaker units are the same right? Only the amp and circuts differ? Only problem is, MX7000 are not that cheap yet (compared to the mx6000). The MX7000 are starting from £400 on dba.dk . My next step is the motor table stand, but they seem quite rare.

My MX6000 says 33/14 EDT SW 1.1 on the sticker on the back.

thanks
