I have this monitor that looks pretty good but the top of the display stretches out and then squeezes towards the top (see picture below.) Must be pretty low hours on it as well because I can find no sign of electrolyte leakage, the caps test out good with BlueESR, even the ones near the big hot resistors and heatsinks are fine. I've gone over the board a few times and replaced two of the transistors that others have reported going bad (Q401 & Q402) but no change. I've also moved around all the pot adjustments on the board (especially V-LIN which expands / contracts the image a bit, but the loss of linearity is relatively constant.)
Does anyone have an idea of which PCB components could lead to a loss of linearity in the current near the top of the scan? Without schematics I'm having a tough time figuring that out.
