Question: I have a Nintendo VS Unisystem upright Super Mario game that the monitor doesnt work. The game has been sitting for several years now because I dont know what to do with it. Game appears to have power everywhere. The monitor pops when the game is powered up like it wants to come on but the monitor stays black. I unhooked the edge connector and got the same results (found it in the manual). The glass tube on the end of the monitor starts to glow for about one second and then goes out. The game does plays blind with sound and everything. Could this be a cap issue or something else? PS I know nothing about these games other than I love to play them and cant afford to pay hundreds of dollars for someone else to fix it. Thanks in advance for any help you can provide.

Response from Jonathan: Most Nintendo cabinets use the Sanyo 20ez monitor. The symptom you are describing sounds like the B+ voltage is set too high on your monitor chassis. You might try turning that potentiometer back to the center along with all of the pots that control brightness. Once you’ve done that, turn the game back on and see how the monitor reacts. If you can, measure the voltage coming off of the B+ voltage pot with a multimeter. It should 110 VAC give or take about 5 volts either way. Hope that helps.
Thank you for your question and good luck with your repair.
