Sony PVM 8041Q
This monitor can display PAL, SECAM and NTSC signals. Uses 250 TV Lines instead of 450 TV Lines (Super Fine Pitch) tube. It should be noted, while some controls are in front of the PVM, most of the geometry and color controls requires manual tweaking inside the PVM.
Common problems
The Sony 8041Q PVM is known to have several problems. The solder used on the boards of this CRT is prone to hairline cracks, and the stock capacitors are known to have degraded by now. Most of the issues can be easily resolved, but the work involved is not light by any means.

Sync issues trouble shooting
- Got a PVM with sync issues. Tested all the inputs and the sync issue was there with all the inputs. Worse with composite compared to RGB.
- Tried swapping B and D boards from a working unit. Found that B board was faulty.
- Tried reflowing all the through hole connections, CN101 and IC124
