CRT Monitor
Servicing
PVMs, Trinitrons, Commodore monitors and VGA CRTs — serviced by high-voltage trained technicians. We replace capacitors, calibrate geometry, verify convergence and send your monitor back at peak performance.

Complexity varies significantly by monitor type and fault

PVM units, large-screen CRTs and complex faults may exceed this range. We'll always quote before proceeding.
How it works
Receive
CRT received and inspected externally. Handling notes and symptoms documented.
Safety Discharge
MANDATORY first step. CRT anode discharged to zero before any case is opened. Every time.
Visual Inspection
Internal inspection of all boards under magnification. Cap condition, trace damage, burn marks noted.
PSU Capacitors
All power supply capacitors replaced. This is the most common failure point in aged CRTs.
Deflection Board
Deflection circuit capacitors inspected and replaced. Responsible for geometry and scan integrity.
Calibration
Geometry adjusted, convergence checked and tuned, colour purity verified on all phosphors.
48h Burn-in
Monitor runs continuously at operating temperature for 48 hours to catch any early failures.
Return
Carefully packaged (CRTs need serious protection) and returned with a full service report.

What's wrong with your CRT?
Most CRT faults are repairable. Here's what common symptoms usually mean.
Single horizontal line across screen
Vertical collapse — deflection circuit failure. Repairable but don't run it — you'll burn the phosphors.
No raster / completely black screen
Could be PSU failure, deflection failure, or dead tube. Diagnosis required.
Geometry distortion — bowed or trapezoidal image
Deflection cap failure or yoke problem — very common on 20+ year old sets
Colour purity issues — patches of wrong colour
Degaussing circuit or shadow mask issue — often fixable via service adjustments
Convergence problems — colours don't align
Convergence board or purity magnets need adjustment. Common on PVMs.
Brightness / focus drift over time
Focus cap or flyback issue — monitor needs service before it gets worse
Capacitor smell — hot electronics odour
A cap is failing under load. Turn it off immediately and have it serviced.

Common questions
Is it really that dangerous to open a CRT myself?
Yes, genuinely. The anode capacitor in a CRT stores 25,000 volts or more — enough to stop your heart — and it holds that charge for days or weeks after being unplugged. Even experienced technicians discharge CRTs before touching anything. We never skip this step. Please do not open a CRT yourself.
How do I ship a CRT safely?
CRTs need substantial padding — at minimum 10cm of foam on all sides. Double-boxing is strongly recommended. We can advise on packaging when you book. We've received CRTs that survived fine and CRTs that arrived as shards — packaging makes all the difference.
Can you restore convergence on a PVM?
Yes. PVM convergence adjustment is a skilled process involving purity magnets, yoke position and on-board convergence controls. We do this as part of every PVM service. Perfect convergence significantly improves image quality.
Why does my CRT need recapping if it's still working?
Working CRTs with original caps are living on borrowed time. When PSU caps fail under load, they can cause secondary damage to other components — and sometimes start fires. Proactive capping is cheaper than reactive repair. If your CRT is from before 2000 and hasn't been serviced, it's due.
