My Seiki works very well but after two minutes it stops and goes into standby.

Probably a failing power supply

The main power supply regulator section circuit fault. Either it will be a separate board, or the part of main board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Pull up older posts. http://electronicshelponline.blogspot.com/ It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.

Hi There, well, it sounds like your motor control board is failing due aging capacitors. Using the unit like this can lead to complete failure and possibly costlier repairs. You can find repairs and refurbs for treadmills by emailing gregATbuyfitnessrepairpartsDOTcom as well as for additional help. There is a power supply circuit on the control board that provides power to your console, if your console goes dead, as in no lights or beeps, the power supply is failing when warmed up. Good Luck!

Hi publicworker,

I had a similar problem whereas my monitor went to sleep mode after a few minutes. I'm running an HP LP 2065 in dual mode with another HP flat screen. However, I did resolve the issue after resetting the output settings.

How to do that:

• right mouse click on the desktop
• select graphic options
• output to
• extended desktop

Maybe some changings/modification will help you too.

Have you disabled "Wake on LAN" in the power settings? There are also other settings in Power management that could affect this.
There should also be general settings for power savings such as "none" "medium" and "maximum power savings" With a little explanation of each.

Press the volume button on the side of the phone to display a screen similar to previous Sony Ericsson Cybershot phones during standby mode. It will display the time and a message icon. This is probably an energy saving feature when the screen goes black in standby mode, but you must press the volume button to get to that screen.

1. Press the [Access A] (key symbol) button on the top, right corner of the Control Panel.
   
   
   
   
2. Enter the system password using the numeric keypad, then select [Enter] on the Touch Screen. The default password is 1111.
   
   NOTE: The default password is 1111. The password will be displayed as an asterisk (*). If you make a mistake, press the [Clear (C)] button and re-enter the password. To cancel the operation, select [Cancel]. If you are experiencing problems with your password or have forgotten your password, contact your administrator.
   
   
3. If the Internal Auditron is not enabled, select the [Go To Tools] button (does not apply to copier-only models). If the Internal Auditron is enabled, select the [Tools Pathway] button.
4. Select the [More] button.
5. Select the [Power Saver Administration] button.
6. Select the [Set Duration Times] button.
7. To adjust the 'From Standby Mode to Low Power Mode' time-out, select that box so it turns black then enter a new time using the numeric keypad on the Control Panel. The Standby to Low Power may be set between 1 - 120 minutes.
8. To adjust the 'From Low Power Mode to Sleep Mode' time-out, select that box so it turns black then enter a new time using the numeric keypad on the Control Panel. The Low Power to Sleep may be set between 0 - 120 minutes.
   
   NOTE: There should be a minimum of one minute between the 'From Standby Mode to Low Power Mode' and 'From Low Power Mode to Sleep Mode' settings. For example, if the 'From Standby Mode to Low Power Mode' is set to 10 minutes, then the 'Low Power Mode to Standby Mode' should at least be set to 11 minutes.
   
   
9. Select the [Save] button.
10. Select the [Exit Tools] button.
