Title: Hantarex MTC900 Blur post traumatic capkit Post by: rom1 on November 23, 2014, 12:01:12 pm Hi
My mtc900 monitor had recently its flyback out of service i I had a old other one working but bad and I ordered a capkit on eBay. I replaced all the capacitor concerned by the one supplied ones. A colleague of me checked my work and it was ok as you can see in this first picture. (http://www.flipjuke.fr/download/file.php?mode=view&id=111814&sid=505b3cd1710a5c318e4e59613a232456) I mounted the chassis on the other tube where the other that was off. The pict was jumping and blur. I thought i cames from the tube so i decided to replace it to by the other which was working with this chassis. And... same result You can see it here : https://www.youtube.com/watch?v=cAwH8UjCr4o (https://www.youtube.com/watch?v=cAwH8UjCr4o) The turnings (horizontal, vertical, neckboard blur) have no effects. What is going on???? Could you please help me ?

The rings of the yoke have no action too. A guy said me that perhaps the potentiometer of the neckbeard is out of service. What do you think? Title: Re: Hantarex MTC900 Blur post traumatic capkit Post by: computerfixerguy on November 26, 2014, 11:01:31 pm Did you replace the flyback yet?

So i replaced the neckbeard and then... The image is clear and no more blured, but... No synchronisation :-( The tunings at the back of the chassis have no effects : https://www.youtube.com/watch?v=kQQYM1-v4gY (https://www.youtube.com/watch?v=kQQYM1-v4gY) Perhaps it is a problem of voltage, what do you think ?

A wire between 2 cards of the chassis (synchronization inverter) was deluged. I got the focus and a very good image, but... As I moved the cab to his place back et restarted it : the pict is totally blured, grrrrr !

Juts a trouble of width, not controlled by the good pot (RV20, pin cushion in place of 18, width) a,d th epic is too straight. But it is playable for now... ;D |
