Power supply damaged, Can I replace it with any other model power supply?


A standard ATX PS won't fit in your low profile case. The plug types can be different too. Usually there's a schematic with a PS that describes the wire color of each voltage. So you could conceivably shove the pins out of one PS plugs and insert them into the different plug, or solder the wires to the correct pins, and leave the PS outside of the case.

Samsung printer 110v plug to 220v


You would have damaged the power supply section but in many cases the front end contains a surge protector with a variator which will short and blow the fuse. So check fuse replace and check for short in the input circuit of the power supply, if the Switch mode is damaged then you need to replace the unit with a 220 volt type or if only the 110 type is available then use a step down transformer to down the mains to 110V with about 0.5Amps

In asus P5GL-MX mother board the power supply regulator ic 2 piece has been damaged (short) how would i know plz help me


Hi if the regulator ic has been damaged in your power supply even you replace that there are some electronic component where also damage because the ic will not damage where there is no over voltage flow on it. This means there are some resistor or a transistor is also shorted it advisable to replace a new one than to repair your power supply. Because even you repaired it the performance and the life span of your power supply is not stable. So it better to replace a new one.

I have printer 5550 problem power i changed fus then i conect power then damage fuse again whats problem.


The power supply in the printer is shorting out the mains input. Its always best to replace the power supply unit for a new one.. If you go to HP Partsufer (google it) you will see if the PSU is available. Alot of HP parts are not available but you should be ok on this one though.
Good luck

My power plug had electric shock while i was watch tv now my tv doest work


Hi,
Your unit has fuse protection for AC supply malfunction like the short circuit. You must take it apart and check this fuse, for sure it is already blown. Pull-out it in the board and replaced it with same current (ampere) and voltage ratings.
Replace also your power cord to ensure that same cenario will not happen again.
Visit your local electronics supply for the replacement, this parts are widely available at the market.
Hope I helped you.
Have a nice day!
Thanks for using Fixya.

Need to know "no bus" indicator light on instrument panel....


"No Bus" means the data cable going to the (PCM) computer is unplugged, or the PCM has failed and not able to read the information it is being given.
Sometimes just jiggling the PCM causes the ODO "NO BUS" to come on.
Sometimes a bad crank or cam sensor can cause this as well.

Here is the OFFICIAL checklist for the "NO BUS" condition....

Vehicle: 1998 - 1999 Dodge Durango 3.9L
2000 - 2001 Dodge Durango 4.7L
1998 - 2000 Dodge Durango 5.2L
1998 - 2001 Dodge Durango 5.9L



Symptom: Engine will not start. Gauges are inoperative. No BUS message displayed on odometer.



System: Body/Chassis Electrical, Emissions/PCM/Fuel, Engine Electrical



Codes: N/A



Problem 1 of 6: The 5v power supply from the Powertrain Control Module (PCM) is shorted due to a shorted Crankshaft Position (CKP) Sensor.



Test & Fix: If the 5v power supply circuit is shorted to ground, the CCD bus is unable to transmit messages and the Powertrain Control Module (PCM) appears to be "dead". The PCM is not damaged when the 5v power supply gets shorted to ground, but does need to be reset by turning the key off for 10 second after the short is removed. Using a DVOM or labscope, measure the voltage on the 5v reference wire at the Throttle Position Sensor (TPS) or Manifold Absolute Pressure (MAP) sensor. If 5v is not present, unplug the Crankshaft Position (CKP) Sensor. Turn the key off for 10 seconds. Turn the key on and measure the voltage on the 5v power supply circuit. If the voltage is now 5v, replace the CKP sensor.



Problem 2 of 6: The 5v power supply from the Powertrain Control Module (PCM) is shorted due to a shorted Camshaft Position (CMP) Sensor.



Test & Fix: If the 5v power supply circuit is shorted to ground, the CCD bus is unable to transmit messages and the Powertrain Control Module (PCM) appears to be "dead". The PCM is not damaged when the 5v power supply gets shorted to ground, but does need to be reset by turning the key off for 10 second after the short is removed. Using a DVOM or labscope, measure the voltage on the 5v reference wire at the Throttle Position Sensor (TPS) or Manifold Absolute Pressure (MAP) Sensor. If 5v is not present, unplug the Camshaft Position (CMP) Sensor. Turn the key off for 10 seconds. Turn the key on and measure the voltage on the 5v power supply circuit. If the voltage is now 5v, replace the CMP sensor.



Problem 3 of 6: The 5v power supply from the Powertrain Control Module (PCM) is shorted due to a shorted Manifold Absolute Pressure (MAP) Sensor.



Test & Fix: If the 5v power supply circuit is shorted to ground, the CCD bus is unable to transmit messages and the Powertrain Control Module (PCM) appears to be "dead". The PCM is not damaged when the 5v power supply gets shorted to ground, but does need to be reset by turning the key off for 10 second after the short is removed. Using a DVOM or labscope, measure the voltage on the 5v reference wire (5v power supply) at the Throttle Position Sensor (TPS) or Manifold Absolute Pressure (MAP) Sensor. If 5v is not present, unplug the MAP sensor. Turn the key off for 10 seconds. Turn the key on and measure the voltage on the 5v power supply circuit. If the voltage is now 5v, replace the MAP sensor.



Problem 4 of 6: The 5v power supply from the Powertrain Control Module (PCM) is shorted due to a shorted Throttle Position Sensor (TPS).



Test & Fix: If the 5v power supply circuit is shorted to ground, the CCD bus is unable to transmit messages and the Powertrain Control Module (PCM) appears to be "dead". The PCM is not damaged when the 5v power supply gets shorted to ground, but does need to be reset by turning the key off for 10 second after the short is removed. Using a DVOM or labscope, measure the voltage on the 5v reference wire (5 volt power supply) at the Throttle Position Sensor (TPS) or Manifold Absolute Pressure (MAP) Sensor. If 5v is not present, unplug the TPS. Turn the key off for 10 seconds. Turn the key on and measure the voltage on the 5v power supply circuit. If the voltage is now 5v, replace the TPS.



Problem 5 of 6: The 5v power supply from the Powertrain Control Module (PCM) is shorted due to a shorted wire.



Test & Fix: If the 5v power supply circuit is shorted to ground, the CCD bus is unable to transmit messages and the Powertrain Control Module (PCM) appears to be "dead". The PCM is not damaged when the 5v power supply gets shorted to ground, but does need to be reset by turning the key off for 10 second after the short is removed. Using a DVOM or labscope, measure the voltage on the 5v reference wire at the throttle position sensor (TPS) or manifold absolute pressure (MAP) sensor. If 5v is not present, unplug all sensors that are connected to the 5v power supply and disconnect the PCM. Check if either 5v power supply circuit is shorted to ground using a DVOM. If the circuit is found to be shorted to ground, repair the wire and the cause of the short.



Problem 6 of 6: The 5v power supply from the Powertrain Control Module (PCM) is shorted due to a shorted Governor Pressure Sensor.



Test & Fix: If the 5v power supply circuit is shorted to ground, the CCD bus is unable to transmit messages and the Powertrain Control Module (PCM) appears to be "dead". The PCM is not damaged when the 5v power supply gets shorted to ground, but does need to be reset by turning the key off for 10 second after the short is removed. Using a DVOM or labscope, measure the voltage on the 5v reference wire at the Throttle Position Sensor (TPS) or Manifold Absolute Pressure (MAP) Sensor. If 5v is not present, unplug the large round connector on the driver's side of the transmission. Turn the key off for 10 seconds. Turn the key on and measure the voltage on the 5v power supply circuit. If the voltage is now 5v, remove the transmission pan and check for shorted wiring inside the transmission. If the wiring is OK, replace the Governor Pressure Sensor.


Many times the PCM simply overheats - and changing it will stop the problem.

2000 Ram 1500 4x4 "no bus"


All the modules are connected together to communicate with each other via the PCI bus. It is possible that one of the modules is pulling the bus down. If the vehicle won't start it could be any one of the modules. It will be a process of elimination to find the faulty one by disconnecting them one at a time.

Need power supply diagram


Without the model number, there is little we can do to help. Also, many of these are not generally available. The good news is that many power supplies for VCRs are relatively simple to fix. Are there any symptoms at all or is the unit completely dead? Check the transistor that is attached to the heatsink for shorts. Normally that is the first item to get smoked when the power supply fails. Then check the 160V+ capacitors. There will likely be a 2.2ufd cap on the primary side that is defective. Change it and try again.

If the above does not resolve the problem, update this and we'll continue.
