Power supply When starting the thinkpad with the on button the disk led flashes for a very short moment and the battry led extinguishes while lighting up shortly thereafter. The machine does not make a single sound. Is this a known problem? I tried another power brick, same result, I took out the Hard drive, same problem. I removed the internal modem, same result. I detached the battery, same result.

just cause your power supply is tested good doesnt make it good it could be a shorted panel or more likely the leds behind it unplug everything except the remote eye mainboard and buttons from the power supply and see if the light stays on if it does then i would look into the led strips also check the flash's i dont remember if samsung has a set amount of flashes = a code

If you are not getting the computer to start up but you are getting the fans to whir for a moment and the keyboard lights to flash, then that means that you probably have a bad motherboard. If you had a bad power supply, most likely none of these secondary indicators would be present. I would advise taking the computer to a local computer repair shop and having a professional investigate the problem. More than likely, he will be able to tell you the cause of your problem in short order.

chk PSU and see if its on 110 or 208 maybe...might be showing bad power...or the MB isant happy...MY GUESS

You may want to shop for that board or at least consider removal of the HDMI socket in question---tested for shorts there I presume?

Common problems on Sharp LCD tvs as tv it is agings,tv Power LED and OPC LED,LEDS lights flashes happen to mine Sharp tv many times and i had it two years,do this many times,tries to turn on the tv.By trying pushes the power button the remote again if OPC LED and power LED,LEDS lights flashes together.Everytimes the OPC LED and power LED lights flashes,just push the power switch on the tv remote and wait for the tv main Tuner signal board to kick in the backlight to light up tv to work.Have to do this like three or four times before the power supply board to kick it in to make Tuner signal to work.If u require to this more than 5 or 6 times the main tv Tuner signal board it is shorting out and beyond trying to kick in by the power supply board.Tries websites like Shopjimmy.com,Ebay.com to buy a refurbish tv Tuner signal board for the replacement.

All i had to do was SYNCHRO the board by pressing the synchro button on the wii balance board were the battries go, the power LED will blink (note once the power LED has started blinking, stop pressing the synchro button)
THen you need to press the synchro button on the wii console, while the wii balance board's power LED is blinking
