Time and skill are required to diagnose televisions. The majority of this time and skill are spent on diagnosing TV's. Once we find the solution, the repair is rather straight forward. The diagnosis fee helps cover at least part of the cost we incur in labor diagnosing the unit, and travel expenses if we are making a service call to your home. We do not make money giving estimates; We make money by repairing televisions while keeping our customers informed.
