Default VXL 3s power issues - thoughts?

I pulled my vxl out of my slash and put her in my scx-10 with some paddel tires for some hill climbing fun FOFF style, i had her running inside of the house - got her dialed in and programmed and such. removed the battery, recharged it and set her on the shelf. 1 week later - i pullher off the shelf - repeak the battery - take her out to tear it up and the servo will power up but the throttle is none responsive. i put a cheap brushless esc on the velinion motor - works like a champ - i then put another motor on the velinion esc.. nothing. the power button will turn it on (no indicator light) but the steering works - but then i cannot turn it off (have to pull the battery). I also tried 5 different battery packs (thought i was loosing my mind) ..... could it be something in case under the power button?

Has anyone esle ran into this? I have not called Traxxas yet due to that i am the 2nd owner of his system and the "repair" cost is $55 plus my shipping it out there.... i can get another used one off of ebay for that price.

Any info you have would be great!

I just purchased a unit from someone on RCC. He had sent the item in with what I think was similar issues. He found out it is a problem with the on / off button (Dirt) on the ESC. For what this information is worth.

just took it apart - nothing looks "burnt" - no dirt in the switch - the led does not come on. im about ready to crack it open and toss it into a baggy of uncooked rice to pull any moisture out of it that may be there. anyone else have this? The only way i can tell it is on is that the servo starts to respond.

battery is not reversed. i tried multiple batteries. i did find something different though. when power on (remeber - no led light - only servo works) the motor is acting like a drag brake... wierd? i have no led and no throttle but it is acting like a drag brake = hard to roll.

I had the EXACT same issue with one.Traxxas tech said it was in fact dirt(microfine) stuck in the button.They sent me a new one one but i hadnt had it very long,so they didnt charge me.I have since experienced the same issue with dirt in the new one.I blew it out with 125psi,then sprayed wd-40 and next i will brush on some "liquid electrical tape" just over the button.Hopefully that will keep out the microfine sand.Thats what i run in mostly

It's possible the mechanical part of the switch is getting jammed with sand, but what it's operating is sealed in a bladder, thus waterproof.
