If your monitor only displays a thin horizontal line in the middle, check the IC (Integrated Circuit) that powers the vertical to see if it is good and to see if it is getting power. A cap kit is easy to do and cap kits are pretty inexpensive. It’s a good idea to go ahead and replace all the caps if you are going to do one. A bad electrolytic capacitor will often swell or bulge at the top or leak out of the bottom, however, they can still be bad even if they don’t look bad. Some signs that might you need a cap kit include washed out colors, vertical drop, and/or lines across the top of the screen. If upon futher examination you find that the casing is in fact cracked, replace the flyback.Īnother good thing to know is that while cap kits can be helpful they will not fix everything. If you hear a hissing noise around the flyback that might indicate that the casing is cracked. If it is shorted, that’s a good indication that you have a bad flyback. If you suspect flyback trouble, the first thing to check is the HOT (Horizontal Output Transistor) with a standard multimeter to see if it’s shorted. A flyback can put out a large amount of volts depending on the chassis. The wire coming out of the suction cup is attached to the flyback. Please be careful around the suction cup as it contains an anode that goes to the monitor tube. We have already talked about how dangerous arcade monitors can be in our Safely Discharge An Arcade Monitor post, however, this point can not be reiterated enough. You can refer to our article on Checking Fuses With A Multimeter for more information on fuses. Check the surrounding components and make sure that they are not shorted to ground before replacing the fuse. There is always a reason why a fuse blows. If the fuse is bad, replacing it might not solve your problem. If so, check the fuse to see if it is bad or good. Check to see if there is a fuse around this area. This should lead you to the primary power supply. Follow the power cord from the connector to the chassis. If your arcade monitor won’t come on, a good place to start is in the power supply.
