Computer Crashes and Electrolytic Capacitors

Electrolytic Capacitors are something to keep note of when troubleshooting computers that crash. Symptoms can be: Will not boot, have distorted or no video, randomly shut off or on, distorted or no audio, or just do random and crazy things. Electrolytic capacitors can be found on a lot of electronic circuit boards (motherboards, video cards, sounds cards, power supply boards, network cards, etc). They look like a long cylinder with a stripe down one side indicating the negative polarity lead.

When looking for bad capacitors always check the motherboard first. The motherboard will typically have electrolytic capacitors around the processor. You then want to look at the card directly involved with the failure. If everything still looks good, then it can also be in the power supply. With general symptoms and where to look: Issues with powering on and off (motherboard and power supply), issues with video (motherboard and video card), issues with sound (motherboard and sound card), and etc.

Some general tips on recognizing a bad capacitor is looking at the top and bottom. The top should be flat, so if you see it bulging out, then it's bad. You also want to look the tops and bottoms over for any brownish substance leaking out. This substance is the electrolytic part of the capacitor and it can do damage to circuit boards. It can eat through traces, solder pads, through holes and cause opens that can't be fixed. Any time you see this on a circuit board, look it over very closely for damage after you remove the capacitor and clean the electrolytic off. I just use rubbing alcohol on a Q-Tip to remove electrolytic from a circuit board. Some manufactures use glue, epoxy, or silicon on parts to bond it to the motherboard. Don't confuse glue for a leaky capacitor. That stuff should be hard and not clean off with rubbing alcohol.

Electrolytic capacitors are usually easy to replace using a soldering iron, solder wick, solder, and side cutters. Make sure you put the new capacitor in with the stripe on the same side as the one you took out. If you don't, it could explode. Always wear safety glasses!

P0627 on a ford ranger tdci canot find those modules and relays to check

n the event of fuel pump "A" control circuit fault, a trouble code will be stored and a service engine soon lamp will be illuminated. Some models require multiple drive cycles (as many as 8) with a failure in order for the service engine soon lamp to be illuminated and others will activate it on the initial failure. The "A" refers to more of an area of malfunction as opposed to a particular circuit or component.

Symptoms

Symptoms may include a stored trouble code, an illuminated fuel cap malfunction lamp, and possibly an illuminated service engine soon lamp. If this code is stored, and a service engine soon lamp has not yet been illuminated, the code may be shown as pending.

Common Causes

The most likely cause of this code being stored is a defective fuel pump or relay. Most fuel pump control circuits are integrated into the PCM. Other causes may include corroded, open, or shorted wiring or connectors in the CAN Bus harness, a loose control module ground strap or broken ground wire, the CAN bus may also be defective

Whats the codes p0685 an p0688 on a 2004 chrysler pacifica mean

P0685 CHRYSLER - Auto Shutdown Relay Control Circuit Failure

Short or open in Auto Shutdown (ASD) relay circuit
Symptoms
- Engine Light ON (or Service Engine Soon Warning Light)
Possible Causes
- ASD relay circuit is open or shorted
- Failed Auto Shutdown relay
- Failed ECM
Tech Notes
Check all the ECM fuses, if the fuses are OK try replacing the ASD relay.

P0688 CHRYSLER - Auto Shutdown Relay Control Circuit Low

The Front Control Module (FCM) has detected the supply voltage below an acceptable value
Symptoms
- Engine Light ON (or Service Engine Soon Warning Light)
Possible Causes
- ASD relay circuit is open or shorted
- Failed Auto Shutdown relay
- Failed ECM
Tech Notes
Check all the ECM fuses, if the fuses are OK try replacing the ASD relay.

My microwave seems to have a mind of its own it keeps wanting me to reset date and keeps beeping for no reason at random times

Most likely it's an electronic failure of the main circuit board. Although extremely unlikely, I have seen an oven or two that have had these symptoms that were caused by an insect walking on the back of the circuit board.

Screen flicker

RAM failure. Could be on the Graphics card or the main computer RAM may be at fault. But, as you don't ask a question or give us a decent description of the symptoms, we can't help any further than that.

Replacing temp sensor

Intake Air Temperature Sensor Operation The Intake Air Temperature (IAT) sensor is a variable temperature sensitive resistor. Sensor resistance will change based on air temperature. The higher the temperature, the lower the resistance. The Engine Management System (EMS) provides a reference voltage and monitors the voltage drop between a fixed value internal resistance and the sensor resistance. This is called a voltage divider circuit.
IAT sensor values are used by the EMS to assist with the calculation of idle speed, fuel mixture and spark advance.
Inaccurate voltages from the IAT sensor may affect pulse-width, idle quality and tail pipe emissions. Intermittent signals may cause hesitation, stumble and surging. If an IAT sensor failure accompanies an Engine Coolant Temperature (ECT) sensor failure cooling fan operation may also be affected.
Some manufacturers' incorporate the Intake Air Temperature (IAT) sensor as part of the Mass Air Flow (MAF) sensor, or air flow meter. Refer to current service information for specific applications.
Related Symptoms The following symptoms can be caused by a faulty IAT sensor due to loose connections, bad grounds, high resistance in the circuit, or opens in the circuit.
  • Extended crank time when the engine is cold
  • Poor fuel economy
  • Spark knock

Can anyone help me to do Video card failure and

As far as I can determine this machine has 'on board' graphics. In other words there is no separate video card - the graphics capability is built into the motherboard.

What symptoms do you have - why do you say 'video card failure'?
