i have a game king touch screen monitor 14 inch and its been fine till today the screen became a little fuzzy on the cards what can i do to make my monitor clear again thanks in advance for your help

I moved your question to the Tech Support board. Hopefully one of our monitor experts will be able to help you out.

The first question is, are you familiar with working around monitors and the (potentially deadly, really) voltage they can contain?  If not, proceed with extreme caution or you could get a very bad  :50- :50- :50-.

Second, are the cards fuzzy when you first turn it on, or only after it has warmed up, or both?

Third, there is a focus adjustment on the flyback (part of the chassis behind the screen), but I wouldn't go adjusting that until you answer question number 2.  That, and it's impossible to adjust it while the monitor is in the machine, making it a difficult proposition to make the proper adjustment unless you have an extension cable to be able to run the monitor outside of the machine.

Fourth, you'll likely want to/need to replace the flyback soon -- it's the weakest link on the monitor and causes out-of-focus issues.  For this you'll need to know safe monitor handling skills and soldering, or take it to a TV repair shop that can do it for you.

Edit: I see from your profile that you're in Las Vegas.  I'm sure there must be a shop there that could do the repairs for you, and would have the necessary cables to test it and make the necessary adjustments.  You likely wouldn't have to bring your whole machine in, either, just the monitor which could easily fit on your passenger seat.

My Game King uses a Ceronix CRT and the display became fuzzy.  If your  CRT unit is a Ceronix, the Ceronix model # will be written on the rear of the tray that holds the CRT and logic board.  On my unit the focus adjustment is on the flyback transformer. The flyback transformer is easy to find as a thick cable goes from the flyback transformer to a rubber boot (looks like a suction cup) which is attached to the top of the glass CRT tube.  There are 2 adjustments on the flyback transformer.  The knob closest to the logic board (on the flyback transformer) controls focus. The other knob controls the voltage going to the CRT.  Neither can be adjusted while the CRT assembly is in the machine.  Remove the CRT assembly. Note the position of the flyback transformer knob closest to the PCB, then turn it slightly and reinstall the PCB and see if the focus has become better or worse.  Naturally these instructions won't be applicable if you don't have a ceronix.   Don't reach into the CRT area while the machine is turned ON as very high voltages exist in this area.  Ceronix is at www.ceronix.com and they have technical info available at their site.

I hope this helps.
