Keeping a capacitor next to the power supply pin on the chip, it steps in and absorbs the transient spike. If one''s missing or falls off, in theory, a big current spike can cause a glitch.

If you were to put a bigger capacitance load on that transistor, it would take longer to charge and discharge and as a result the transistor would have to run at a slower clock speed for us to reliably detect a 1 or 0. Thus processor designers have to worry a lot about capacitors to achieve high clock rates. Now this is a surface capacitor.

The service manual should list what the voltages should be and where to measure them. If you get a noise as the tv tries to turn on, the filter caps may be bad and the power supply doesn''t have enough stored energy to kickstart the tv. Also when you turn on the tv, do you feel static electricity build up on the screen?

It is making an odd noise when I turn it on, I recorded it but the screen does not turn on and the fan does not start. I noticed it was off yesterday. When I turned it back on it was making an odd noise. I turned it off until today when I would have some time to investigate.

But there have been problems in the industry periodically where batches of crappy capacitors got used, and failed early in the computers'' lives. So computer age isn''t a reliable basis for considering or excluding capacitors as a potential cause. But if the computer is very old, the chances of capacitors being an issue is higher.

Supplier reputability. In short, do not get the capacitors from [just any] eBay store or DX. In 99% of the cases, you''ll get fakes - cheap capacitors with a poorly-printed brand name on the label. Have a look at the image at your second link - it''s a mix of "Sanyo" and "Suncon". Yeah, right! Oli has already listed some reliable sources.

If you turn off the breaker then take the light and fan blades off so you''re looking at all of the wiring, then spread the wires apart and turn the breaker back on. Take the multimeter and measure voltage with combinations of wires while you have the wall switch in the "on" position.

View morePower Failure: Capacitors are crucial for smoothing out voltage fluctuations in power supplies. A failed capacitor can lead to power failures or, in severe cases, damage to the power supply. Audio Noise: Audio equipment capacitors are used for signal coupling and noise filtering. Failure can introduce noise or distortions in the audio output.
Physical Damage: Mechanical stress, vibration, or impact can physically damage capacitors, leading to internal short circuits or breakage of the connections. Aging and Wear: Over time, capacitors naturally degrade. Electrolytic capacitors, in particular, can dry out, losing their ability to store charge effectively.
Measure across both sides of the capacitors in resistance (or continuity) mode to see if it is shorted. A short would be an indication that either the capacitor is defective or something else on that line (upstream or downstream) is defective. If you have access to an LCR meter, you could desolder the component and test it directly.
When a capacitor is suspected of malfunctioning, performing electrical tests is essential for confirmation. Utilizing a multimeter with capacitance measurement capabilities, or a dedicated capacitance meter, technicians can compare the actual capacitance value to the rated specifications.
Risks: A damaged casing can expose the internal components of the capacitor to the environment, leading to rapid deterioration and failure. Appearance: Rust or corrosion on the capacitor’s terminals or casing indicates aging or exposure to harsh environmental conditions.
Voltage Surges: Exposure to voltage levels exceeding the capacitor’s rating can lead to the breakdown of the dielectric material, failing. These surges can be sudden and unexpected, often from power spikes or lightning strikes.
