How to fully check a Sony PVM M Series - PSU Voltage, CRT Beam, Service Menu & Must Change Caps!
Channel: Retro Tech
Date: 11/01/2021

In this episode I do a complete thorough inspection on a Sony PVM 14M2U CRT.  This professional video monitor was purchased by my client and then mailed directly to me from an eBay seller.  This CRT needs to have some vital capacitors checked and replaced.  I will also show many tips to test other things like the voltages coming out of the Power Supply and how to properly check your beam convergence.  Please join me as I try to save this lovely piece of vintage broadcast hardware.
