Also, its good practice to take general safety precautions - avoid potentially high voltage areas (anode, flyback transformer, neck board etc.) whilst working wherever possible, have a buddy nearby to call an ambulance, keep one hand behind your back when prodding around with a screwdriver, dont repair a CRT in the bathtub etc. etc.

The Sony PVM-14M2 is a 'Professional Video Monitor' produced by Sony in the late 90s - branded under the Trinitron label. This curved glass CRT (Cathode Ray Tube) monitor feautures a 'box' type chassis, as well as 'professional' spec video inputs/outputs via 75Ω BNC jacks.

Naming Convention

There are three variants of the PVM-14M2, based on regionality: The PVM-14M2E; PVM-14M2U and the PVM-14M2A.

PVM

"Professional Video Monitor" - Sony's branding to highlight the 'professional' features, and distinguish from 'consumer' televisions/monitors.

14

The size of the screen in inches.

M

A model distinguisher.

2

Distinguisher based on the 'TV Lines' of the display - in this instance, 600TVLs (vs the 14M4 variant, which has 800TVLs).

E/U/A

Regional variants: E for Europe; U for United States; A for Australasia

Disassembly Notes

As with all CRT (Cathode Ray Tube) devices, it is crucial to have an awareness of the high voltage safety risks inherent. There may be lethal voltages present despite the device being powered off and unplugged.

To reduce this risk of death/injury/pain you must properly discharge: The anode delivering power to the tube; the tube itself; all large capacitors present (there are a couple big boys on the Power Supply PCB) and anything else that may be holding a nasty charge.

Also, its good practice to take general safety precautions - avoid potentially high voltage areas (anode, flyback transformer, neck board etc.) whilst working wherever possible, have a buddy nearby to call an ambulance, keep one hand behind your back when prodding around with a screwdriver, don't repair a CRT in the bathtub etc. etc.

Ultimately however, there will always be risks involved when working with high voltage devices - if you are worried about the risks, do more research! Or alternatively, pay someone else to work on it. You cant be too prepared.

Read tutorials, watch videos, consult forums on CRTs/CRT safety before disassembly.

Original Parts

These table are a more concise copy of the electrolytic capacitors in the linked service manual.
