Tri-State module is not someone I can recommend to do business with. When my optical block went out, I scrapped my TV out and contacted TSM to see if they were interested in buying the optical block so they could rebuild it and resell it. They replied yes and that they would give me $50 for it. I spent a good hour removing it from my TV, carefully packaging it, and mailing it to them. That was 5 months ago and I have still not received my money. I contacted them numerous times and would never get a reply back from them. I filed a complaint with the Better Business Bureau and TSM keeps promising to pay me (only to satisfy the BBB), although they never have to date. I know its only $50, but is the principle that you should be able to trust a business such as this. Bad and unethical of them to treat a customer like this.
