Just like the topic says. I have a 15" (or 14, not sure) Magnavox monitor that has a really really fuzzy picture. Is there anyway to adjust it? It dosent have an onscreen display, just knobs to adjust the size. I hate to throw it away if its something minor, but if it is too much to fix, to the dumpster it goes.
some have a hole in the back to stick in a small flat blade screwdriver
to adjust focus. others u have to remove the back of the monitor to
get at the focus adjustment. warning: high voltage inside monitor,
dont touch the thick high black voltage wire coming out the back of the
picture tube. dont go near it. dont open up back of monitor if your
in a room with pets, or have shaking hands, or are drunk , etc.
Just an update. I found the place to adjust it on the side of the flyback transformer. I must say that little monitor looks pretty sharp now (no pun intended ). I guess it has been saved from the dump for a second time.
Now if I could only get the Packard Bell monitor from showing purple/red all of the time.....
When making these adjustments around Hi-voltage it is advisable to go to Radio Shack or any electronics supply shop and purchase a set of plastic (or nylon) screwdrivers that are non-conductive and specifically for this purpose.
They are relatively inexpensive and beat the hell out of an accidental shock.
It's also good to practice the left hand rule..... stick your left hand in a pocket so it can't touch any part of the chassis or something you could ground thru.
The danger is that the current enters thru the right hand, passes thru the heart which is anatomically on the left side of your body and exits out your left hand. By removing the left arm as a pathway you minimize the danger of inducing potentially fatal fibrillation in the heart from an accidental shock.
Where would the focus be, on or a round the flyback?
). I guess it has been saved from the dump for a second time.
