When a i ibomber defence game bad capacitor is found in a monitor, the question of course arises as to the likelihood of other capacitors going bad in short order.
Most likely cause is driving the monitor with an incorrect scan rate.
Perhaps, the monitor is sensitive to being on dangan ronpa episode 8 a slightly different voltage.Note that if the change is very small - say, less than 1 or 2, then it may simply be normal for your monitor due to poor design or the use of inferior components - some parts associated with power supply regulation may be changing.With modern CRTs, the filaments can be left to minimize the time needed for a picture to appear since this doesn't affect CRT life very much.A condition with somewhat similar symptoms is bad focus - fuzzy picture - but only with bright (high beam current) scenes.Dried up electrolytic capacitors leading to startup and regulation problems.Base drive to the horizontal output transistor is failing - could be a fault in the horizontal oscillator or bad connection.This might be the case if you try to run on the same circuit as an active dimmer or something else with thyristor control.The detection circuit could be in the power supply or horizontal deflection output circuit.Most - but not all - monitors can be safely and stably positioned either still on the tilt-swivel syncios data transfer key base or on the bottom of the frame.Does this glow disappear indicating that the deflection/HV is shutting down?Remove the case (unplug it first!) and start at the line connector.This noise may be barely visible as a couple of jiggling scan lines or be broad bars of salt and pepper noise, snow, or distorted video.However, it may be difficult to measure as the resistors in the voltage divider network may be quite large - hundreds of M ohms.Early PC monitors, video display terminal monitors, and mono workstation monitors use digital input signals which are usually TTL but some very high resolution monitors may use ECL instead.Of course, you usually maintained a full time technician or engineer to fiddle with the convergence adjustments!The flyback is the thing with the fat red wire coming out of it (and perhaps a couple of others going to the CRT board or it is near this component if your set has a separate tripler) and may have a couple of controls.
Even a pulsating light bulb may just mean that the light bulb is too small for the monitor power requirements.
Is digital worth the extra money?" There is no inherent reason for a digital monitor to have a better picture but as a practical matter, I would expect this to be the case in the vast majority of monitors - especially models from the same.
Here, the failure is not in the power supply itself but may result in damage to it or other components especially if it continues to run in this state.Items (1) through (3) are somewhat independent (though not entirely) of scan rate.If it breaks off or is unreachable, you will need to replace the connector (unless the shell comes apart which is usually impossible or at least not easy on newer monitors).The output of the UPS's inverter should be free of any power line noise.Vertical drive/output which feeds vertical deflection yoke.If this is the case, you may be able to float the filament and live with the short (see the section on: "Red, green, or blue full on - fog over picture".If the pincushion controls have absolutely no effect, then the circuit is faulty.If you have the schematics, check them for 'pincushion' adjustments and check signals and voltages.
Some examples of common termination problems: Overly bright picture with trails following vertical edges, perhaps with periodic ringing.
What appear to be "dark spots" on a solid gray image may actually be beam mislanding (color purity) problems, which may to some degree be remedied by degaussing the monitor.
