Hi all! Ok got my little 1084 monitor foxed and powers up nicely BUT now the display is kinda distorted. Half of the screen is kinda pinched at the middle to the bottom of the screen while it get's bigger from middle to top. Before I saw this I had a screen that the top menue bar was way up in the screen that I couldn't see it so I checked if I could adjust the V-Size and the V-Position that kinda corrected the problem but now I have this screen distortion problem and need advice on how to correct this (if I can). THANKS!! |

I do not have much experience with CRT repair but I believe this is likely due to a leaky capacitor in the vertical oscillator circuit. Do you have a schematic for the monitor? |

Serge125 you already posted about this here: https://www.eevblog.com/forum/repair/crt-monitor-display-distortion-problem/ It really helps to put the make/model number in your posting title. |

Reading your schematic, the problem is somewhere around I 301. |
