Asking help from Chile, STT8300 shutter issues

Hello. My 10 years old STT8300 camera (SN T13060398) worked fine until two months ago. From then, it having shutter problems (opened partially, closing not complete, erratic). I dismantle my system and cannot see any mechanical problems. I was reading topics here at the forum with similar issues but have not friction, screws or mechanical causes to solve. I tightened a little the rubber band of the motor, not response.
My optical train: AO-8, FW8G-STT (filterwheel with autoguider), STT8300.

I contacted Colin Haig by email and He send me a reparation form to fill and deploy the camera, but for me it's very hard to send my precious camera to the other side of the planet with uncertainy about dates, prices, insurance themes, and finnally if the old camera will have real reparation or not.

I would like to try some suggestions before intending "the big voyage" around the world...
Can you help me, please ?

(excuse my english)

After some months, no suggestions from Tim or someone else...
Colin, may I send the camera directly to Bill at California, or I must send it to Canada instead?
Do you advice Bill about that (Bill is not answering emails from common people) ?

Greetings,
Pedro Goles

 

Finally, after 4 emails in last 6 months, Bill answer me.

It's a brief response, only a word, even him don't sign his email...

Good bye Sbig ! I would consider another company for my next camera, a company that gives support to the consumer
