Sony PVM-9044QM Servicing

Something a little different, but in the current age of ‘disposable’ consumer electronics that are glued together it was a pleasant surprise to see how nicely designed this Sony broadcast/field monitor was for regular & easy servicing. Not sure if it’s actually savable or whether the phosphors are just past it, but I have to read more of the service manual before I begin twiddling any of the 50+ (!) adjustment potentiometers…

Disclaimer: prodding the wrong part of a CRT can be fatal, even after it has been disconnected from the mains.

Once you lift the case off the sides just hinge down to expose the potentiometers, with all the wires still attached so you can make adjustments whilst the unit is running.

Just an idea of how many adjustments there are, this PCB alone has over 30 potentiometers…

Once you’re done tinkering the PCBs just hinge back up!

  1. maybe a late comment :P

    i have a PVM-9044QM too, there is only 1 problem, it won’t degauss when switched on.. what can i do??

    1. Interestingly, my BVM-9044 (the broadcast variant of the PVM-9044) doesn’t seem to degauss either on power on… Or does it do it very quietly? Picture sure seems fine though…
