Hello, yesterday my xs35gt shuttle went off with the power supply LED that flashed intermittently. I tried to remove the shuttle from food supply and the LED turns on normally without flashing, when I connect the power supply to the shuttle, the LED starts to flash and the shuttle will not turn on.

.5 volts isn't right for any voltage, you need about 6 volts on the standby voltage on your set, see if you have that, if not try a new power board and see what happens.

Sounds like a power supply issue. Could be weak capacitors onthe power supply. You can get the power supply board from www.tvrepairworld.com

Hello here is others with the same problem:

It looks like the power button is failing.

The fault could also be the mainboard.

Try also to talk with a autorished dealer or a repair shop.

Good luck

HP xw6200 Workstation - Diagnostic LED Code: Four Flashes ISSUE: When the workstation is powered on, the front LED might flash red four times, once per second, followed by a two second pause. SOLUTION: The front LED flashing four times is a sign of a power failure. To fix this issue, complete the following steps:

1. Open the access panel, and check to see if the four-wire power supply cable is properly connected to the system board.
2. There may be a faulty device. Locate it by removing all devices and then reinstalling them one at a time until the workstation fails. Replace the device causing the failure. Continue adding devices to ensure all are functioning properly.
3. Verify the power supply functionality, as follows:
   1. Disconnect AC power.
   2. Remove all internal power supply cables from the system board.
   3. Plug in AC power.
      • If the power supply fan spins, and the BIST LED illuminates, then the power supply is good. Replace the system board.
      • If the power supply fan does not spin, or the BIST LED does not illuminate, replace the power supply.

Have you checked the capacitors? Before I replaced the power supply, I would replace any of the swollen capacitors and all of the transistors on the power supply

Change your BIOS battery.
I have an old Shuttle XPC sn41g2. It's been running almost constantly since it was new. About a year ago it started to be difficult, it was difficult to start and sometimes I had to try several times before it started. At the end I had to disconnect and reconnect the mains supply everytime i had to reboot the PC. Then one day I discovered that the prosessor was running at the lowest standard frequency so I went to the BIOS to set it right, did so and rebooted, and the prosessor stil wouldn't run right. After some thought I changed the BIOS battery, went to the BIOS, resat all settings, then it rebooted normally and since it has been running like new.

Hello,

What model Western Digital USB drive do you have? The problem is the power supply is bad, the flashing light is it trying to power up and failing so it tries again. If you et me know what model I should be able to help more.

Hi there
Try One of the following steps:

1. Flash Youre MB BIOS.
2. make sure that CPU Fan is working OK.
3. Is the CPU attached to the MB correctlly.
4. Is the CPU Fan base and scrowse faremly scrowd and positioned on the MB.
5. Chec MB in/pot power pins connections.

Hope That will Help.

The power supply is fried partially, or the motherboard went poof.

It sounds like you have a bad power supply. It will store up a very small amount of energy (enough to run some LED lights) but not enough to power up the system. That's where I would look. If that is not the problem, then I would look to the capacitors on your motherboard. Good Luck!
