Astro City: Blur effect on white writing/object

[@Alaska-]

Hi every one!
Cause a pics worth more then a thousand word (but basically cause i'm not so able with the english )
here's my issue:

When i turn on the cab, the screen is too much bright and it have this blur effect on the writings but generally on all the objects.

After a while (about 4 or 5 minutes) all goes ok. But i think cause it warm up.
Unfortunately after also an hour of playing the issue come back for exemple, when it display the staff roll of the game (after completed it).
Again the writings have this blur effect. So the warming it doesn't work whit this.

I tryed to handle the bright e contrast with the controls under the CP but with the contrast i have no result and the bright control it already is at low.

What can i do?
thx all.

The screen volts pot on your flyback is set too high.

Oh thanks.
So all i hav to do is handle it till i got the issue fixed? Nothing else? sweet!

The pot is on the pcb of the monitor right? is it easy to access or i have to pull out the monitor?

thats the classic fault caused by the 10uf 250v capacitor on the neck card,also check a for a bad solder joint on the crt socket

this is about the most common problem you will see on nanao ms8 monitor and also a 5 minute repair

make sure you use exactly 10uf 250v electrolitic capacitor with a temperature rating of 105 degree's

I'm not sure i have understand what to do.
Btw "5 minute repair" sound good to me. That means isn't a badbad issue.

So, in order to fix the thing:
i have pull out the monitor from the case right?
then check the screen volt pot and try with that, or the "10uf 250v capacitor" IS the pot?
I don't have knowledge about eletric/tronic stuff so i'm little confused about this point.
Where i have to look to find it?

Discharge the monitor and carefully remove the neckboard. Then replace the circled component (black capacitor) with one of exactly the same value.

[@Alaska-]

well, so it's not use, simply handle the screen volt pot to fix it?
That get much more that 5 minutes for me.. sigh

[grantspain]

well at least you know the exact problem now-you can get someone with soldering skills to fix it for you

[@Alaska-]

Ahah yeah you re right.
Thanks all for such great help.

I'll be back with a monitor explosion issue.

(joke)

i had the same issue, ive changed the 10uf on the neckboard, but the prob was the same...so i changed the 10uf on the main pcb too and the pic looks fine now...

[dmauro]

I had this problem so I simply swapped out the chassis for the other MS8 chassis that I had and it had the same problem just to a lesser degree.

[Devil Soundwave]

Discharge the monitor

As Yosai said! Be sure and Google this *first* as crt can be lethal.

i'm a little confused and worried about this.

9 times out of 10 it will be that cap causing this,those fellas were a bit unlucky
i have had 20 ms8 chassis do this
the key to this is the way the fault manifests itself,it can only be capacitor or bad solder joint related

dmauro fault does not make sense unless he has two faulty chassis or his video input signal is too high

[@Alaska-]

well, the statistc made me a little bit relaxed
ok i have to find the cap and start to work out.

[grantspain]

hey its like everything in life,nothing is ever 100%-you takes yer chances

[@Alaska-]

obv.
Well... i understand your mind and i agree with everything. I just hoped there was a single way for a single problem.
But i know, owning a cab it definitley is not about like own a console or something.
I only have to realize. And start dirty my hands.

[@Alaska-]

ok let's bring this topic to life ..

a week ago i started to look for that transistor in shop around my place... but without luck.
then i heard there was a little shop somewhere and go to check it..

now i turned back home with this black capacitor but again i haven had any luck cause the voltage is higher then the correct capcitor.
10uf 350 v 105 degrees...
i bet this doesnt work... even if the salesman assert that it make no difference..

in any case is that impossible to find this exactly cap?

[cools]

The voltage doesn't matter, as long as it's the same or higher than the original cap it'll be ok.

The capacitance and the temperature rating are the important bits.

so i 'don 't risk anything using that?
