Video Not Working? Fix It Now

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. #RetroTech #CRT #vintage For more information on repairs, diagnostics and to connect with me, please visit: https://www.patreon.com/retrotechUSA The Best 240P CRT calibration suite: http://junkerhq.net/xrgb/index.php?title=240p_test_suite Vertical Blanking/ Red Green Blue Line Repair and Sony Design Flaw: 1: https://www.youtube.com/watch?v=gz9GM7v85n4&t=379s 2: https://www.youtube.com/watch?v=V2EHxGu6vIQ Black RTV Silicone: https://www.amazon.com/dp/B01BWZ1RSK/ref=cm_sw_r_cp_apa_fabc_9.V8FbHSC0GJ4?_encoding=UTF8&psc=1 Dielectric Grease: https://www.amazon.com/dp/B000AL2RI2/ref=cm_sw_r_cp_apa_fabc_ZaW8FbE8CN13C Intro ( 0:00 ) The PVM Arrives from eBay ( 1:00 ) PVM Physical Damage Inspection & Overview ( 3:35 ) Calibration Inspection ( 6:35 ) CRT Beam Convergence Inspection ( 8:11 ) Removing the PVM Shell Properly ( 10:11 ) PVM Internal Inspection ( 11:12 ) Power Supply Inspection and Voltage Testing ( 12:08 ) CRT Teardown - ( 16:49 ) CRT Tube and Anode Cap Discharge ( 17:30 ) CRT Cleaning ( 19:13 ) Internal Circuit Boards Inspected ( 19:58 ) Problem Capacitors located on the Main Chassis ( 24:24 ) Capacitor Replacement Repair and New Caps ( 25:41) Capacitor Testing and Inspection - Failed Capacitor ( 28:46 ) Reassembling the Monitor ( 30:08 ) Service Menu Navigation ( 31:13 ) Calibration Techniques and Overview ( 33:45 ) Dent Repair - Shell Metalwork ( 35:15 ) Securing the Neck Board with RTV Silicone ( 36:53 ) Final Assembly and Testing ( 38:01 ) Outro ( 38:40 )
