Hantarex 900 monitor focus issue

[level42]

Regarding the noob (and with all respect Belike): are you sure that the Flybacks are really bad ? Maybe there is another problem instead ?

[Robinholland]

I think also that the flyback is not broken
Try first your contrast , brightness and maby your screen pot ON your flyback
If this not work do a cap kit

The flyback is for the other 2 monitors, I will try what you advised of course with this one tomorrow(today).
An old friend of mine who is an expert of monitor repairing told me, that the other 2 need a new flyback.
Unfortunately he is not around, he is working for a guy all the time, who is completely insane, he bought about 100 classic pinballs from the past 40 years and planning to open an arcade in the heart of Budapest.

I like this kind of insane people !

Hope he will succeed !!!

And it would give an extra reason for a vist to Budapast !!! (Wish he could hire me, but hey, I'm way too expensive  )

..... maby your screen pot ON your flyback

This model does not have the pot ON the flyback...
it really does not have any pots on the flyback, just on the neckboard.. (wich is a different brightness than the other elsewhere on the board), so i think this pot IS the "screen voltage"

Also people should be aware that if the flyback has gone theres a 90% certain chance the HOT has gone also (I dont have a manual to hand to tell you the part number or location ref sorry)

I did exactly what André and Robin advised, the screen is perfect.
Thanks guys.
All I have to do, is to find some degaussing equipment.

Try a big drill the have a big magnetic field
power it up and go slow away from your monitor
Maybe it works

haha that's the same I have! It looks like the one I spotted on ebay is more solid.

I guess the price is also very reasonable 10$ (excluding shipping)

[Belike]

Thanks for the tips, I think I will try that cheap stuff from Hong Kong after a test with the driller.
I've heard, that a soldering iron could also help in this case, but it didn't work with mine.

[Etienne MacGyver]

The only soldering iron i can imagine that does something like that will be this model:



but then again, only i can imagine, i dont know if it does..

[Belike]

I found this and the seller said it's perfect for degaussing monitors.
What do you think?

The guy from Hong Kong have 122 negative feedbacks in the past 12 months, I would rather pay a bit more and this one is in Budapest.
