Question about Jetway V266B Motherboard

1 Answer

Shutdown Power supply blew a capacitor. Replaced PS, system came up, runs for about 8 to 10 minutes, then shuts down. Can't bring system up again until I wait for about 10 minutes with PS switch off. When system does shut down, it sounds like the HD makes a whirling sound. Tried another HD with the same results. I tried the PS in another system and it runs OK.

IN104 automatic shutdown


Hello, my infocus in104 will power up for a while (1- 5 minutes) when connected to the power supply and turned on, after that it automatically shuts down. Power button does not light red when it automatically shuts down and need to be unplugged for a minute or more before red power button will light up again.

42 plasma tv started experiencing the well known power off red light symptoms. Was able to power on & off for a while to get the set on. Right before the capacitors came in the TV would not power on...


Only if it is completely dead. If you have lights or LED coming on then it's not the main fuse, I would say that you changed the caps, but there are some that you missed. Look hard again and also for maybe a resistor in the power supply.

T.V. was on several minutes later the sound and picture disappeared. Tried troubleshooting in manual but nothing worked, what should we do now.


The unit senses a fault in the power circuit. It is either in the power supply unit (PSU) peripherals or in the PSU itself.
  • One of the peripherals might be loading down the PSU causing it to shutdown.
  1. Check the power input terminals of the peripherals for any short circuit using an ohmmeter.
  2. Replace any part found to be causing the issue.
  • The power supply unit cannot run under load and shuts down. It is usually caused by bad capacitors.
  1. Check the PSU board for any bad capacitor.
  2. Replace bad capacitors with the same specifications.
  3. Make sure to replace the capacitors in correct polarity.
  4. Bad capacitors look like these:3a72a3c.jpg17dffa0.jpg

Computer shuts down.


Hello;

So i guess that the PSU is good. As i diagnose of what you have said, i digested a conclusion that when the computer shutdown when application run. there a problem conflicting the application to another application or such an application trigering the system to shutdown.

Some causes of this problem are:

The system is infected by known and unknown virus
The driver of the system are not properly installed
The application program committed an errors trigering the system to shutdown.

Possible solutions:

1. Scan you system with a potent anti virus
2. Remove the installed driver of the sytem and reinstall it after restarting
3. Unistall the application that causes shutdown problem and you can reinstall it after restarting.
4. remove newly installed hardware or install the correct driver of the hardware.


Note in scanning your system with antivirus you should scan it it safemode.

If all the solution did not work to your system. please notify me for further solution.

Lamp shuts down after startup


it is the power supply/ballast. when you first turn it on, the caps on the ps/bal charge then discharge when the lamp is to strike. if the caps are dried out (from excessive heat), it takes a while to build a charge. so the power drain from striking the lamp brings the ps/bal into shutdown. after you try again, the caps are now up to full power and everything is fine. but every time you unplug it, you'll have the same problem. replace the power supply and ballast.

Presario S4020wm desktop


You need a new power switch. I am currently working on a S4020WM with the same problem. I cut one wire to the power switch, then used a paper clip to make a jumper to start the machine. It has run fine since then. The only trouble I am having is finding a replacement switch.
