If you had your camera repaired by Olympus, please do not pay them another $132. There is a 6 month warranty on the work that they did on your camera. (Please see the note below taken from the Olympus repair info page) I have also included a link to their contact information,
"Note: Actual repair cost may change after the product is inspected. Conditions that void warranty can be, but are not limited to: ***** ***** sand, liquid damage and tampering. All repair work (except minimum repair) is covered by a six (6) month repair warranty. "
If a 3rd party service repaired your camera, you should still have a warranty period. Most services offer a 6 month to one year warranty on repairs of this type.
Please keep in mind that my diagnosis & solutions provided are directly dependent on the accuracy of your description of the problem. As with any "do it yourself" fixes, success is a "team effort", since I can't see or touch the camera, and relies on the customer's manual dexterity and ability to follow the instructions well.

I am assuming that the display shows nothing at all, including menus or image information and there is nothing show at camera startup. If this is the case, then any fix would require disassembling the camera and naturally voiding any warranty. Is the display completely non-functional?
I completely agree and please understand, I am not associated with Olympus, I am just trying to help. Unfortunately I cannot fix bad workmanship on their part.
Not a problem. Thanks for understanding. Have a good day!
