Summary

A CCTV Monitor with good TVL for its size (420). RGB Mod is possible but sort of a pain because it needs to be amplified with a THS3714 (see instructions below). The perfect method of RGB modding this TV is still under dispute/development by several people and will be updated if a better method is presented in the future. At this time I do not personally reccomend investing time or money in this RGB Mod because it doesnt have consistent color levels across multiple input sources. I unfortunately did not discover this problem until after finishing my project.

Notes

Press "Color Up" and "Sharpness Up" simultaneously for 2 seconds to activate the service menu for sub adjustments and h-position. If you get stuck with the service menu displayed even after power cycling the monitor, press "Color Up" and "Brightness Up" simultaneously for 2 seconds to activate the self-test mode and then turn off the monitor. This is the only way I could figure out a way out of the service menu being stuck.

Repair Notes

One unit would shut down a second after it was turned on, which turned out to be caused by a gassy tube which would glow violet in the neck for that initial second. Unit worked perfectly when paired with a properly working tube. I was able to do a tube swap with an A34JLL40X. This required using the original Panasonic yoke or else the raster was much too big on both axes.
