Probation staffers went to Lindsay's Venice house, only to find her on the roof of the building sunning herself and reading scripts. One source connected with the case tells TMZ ... it looks like the device may have "missed a signal." Translation: Lindsay didn't leave the house and therefore didn't cheat.
Sources tell us the Probation people gave Lindsay new monitoring equipment and that was that.
The Probation Department has not formally closed the matter, but one source connected with the case tells TMZ ... "It looks like it's been resolved."
