Question about Dell W3707C 37 in. LCD Television
One of two basic things here, unplug set to see if after a while it helps, and if channel scanning up or down on its own suspect the button associated with the direction it changes is a bad one.

if this is a DELL W3201C read this.
Have the same model and same problem
probably It is a bad inverter board, in my case one of the 16 transformers is burnt out on the inverter board. still trying to find a replacement component. if not replacing the board is the only option or getting the inverter board repaired.
by the way, this TV has a Samsung panel: model LTA320W2-L03. so it needs parts for a Samsong not a DELL.
DELL does not manufacture or fix them becuase they don't make them

without a remote and disabled keypad keys, the only other option, is to open the unit up a physically RESET the TV. remove the cables from the power board. i believe it has a phillips head screw. careful when you separate the rear cover from the front cover. there is a board screwed in the lower right corner, there is a connecter and a ground cable screwed to the rear cover. take your time prying on the rear cover. once you separated the two pieces, look for the light yellow board with your AC power source. Unplug it for 30 minutes and repeat the process. while your at it, also look down to the lower left side of the monitor. u should be able to see the keypad. press each button, while pressing, look to see if the button is pressing against the circuit board. it may be loose, try this test, u just may be able to fix your keyboard as well. hope this works out.

SOURCE: 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.

Power supply module will be the first place to look at, from what you describe, at least the 5v standby power supply is still working, It can be the power supply module is bad or it is not getting the control signal from the main board to turn on the main power supply on.
