! Symptom !! Description !! Common Devices Affected
|-
| '''Bulging or domed tops''' || The capacitor’s top should be flat. Bulging indicates internal gas buildup from dielectric breakdown. || Power supplies, motherboards, CRTs
|-
| '''Leaking electrolyte''' || Brown, tan, or white crust forms around capacitor base or vents. This corrosive fluid damages nearby components and PCB traces. || Analog boards, vintage computers, audio gear
|-
| '''No power / intermittent startup''' || Failed power filter capacitors cause voltage drops or power-up failure. || TVs, amplifiers, game consoles, PCs
|-
| '''High-pitched whining or buzzing''' || Failing capacitors in switching circuits may cause coil whine or unstable oscillation. || Power bricks, CRTs, LCDs
|-
| '''Image distortion / display anomalies''' || In CRTs or LCDs, bad capacitors in video or deflection circuits can cause image ripple, shrinking, or flicker. || Monitors, televisions
|-
| '''Audio distortion or hum''' || Filtering capacitors in amplifiers may leak or dry out, introducing 60Hz hum, buzzing, or reduced volume. || Audio receivers, speakers, synths
|-
| '''Overheating components''' || Failed capacitors cause voltage ripple, making voltage regulators or power ICs run hot. || Any device with power regulation
|-
| '''Reboot loops or crashing''' || Voltage instability causes CPUs or logic systems to behave unpredictably. || Routers, computers, set-top boxes
