Tandy 25-4045 VGM-225 monitor
 |
The Tandy 25‑4045 VGM‑225 is a 14″ VGA/ SVGA CRT monitor originally supplied to Tandy/Radio Shack systems. Common failures on this model include degraded phosphor leading to grainy or washed‑out images, power supply output drift causing flicker or no picture, and connector wear (especially the VGA cable pins). First‑check diagnostics: verify 12 V/5 V rail voltages with a multimeter; inspect the CRT tube for burn‑in or damaged phosphor; examine all VGA and power connectors for corrosion or loose contacts. If image quality is acceptable but no display, test the monitor’s internal oscillator and color amplifier ICs for shorts or open circuits.[oss-gpt-20b] |
