Dell w2600 wont turn
Same problem, this is my solution. The system will start everytime if starting from power off one starts from sleep. Thus the trick is to use sleep mode to shut it down. I do not use the sleep function on the remote (it would be worth a try, let me know if you do that), but rather I have chose VGA as the entry signal ad have hooked the TV to my PC, and then I put the PC in sleep mode. The TV will do the same. When it is in sleep mode through the PC, the system cvomes back to life if the remote from the cable is used to change channels.
