I have a Toshiba 55" standard RPTV (no hd). Currently, I do not have any burn-in. I leave my brightness / contrast down to 45. If I lower it more, it becomes too dark in my pitch black room. I can't take it anymore! I have to start playing X-Box on it. I am paranoid about burn-in so I was wondering if the worse case happened and I burned in the CRTs, how much does this generally cost to repair?? It might be worth the risk if the repair bill wouldn't top around $500. The set is almost 4 years old now so it could use a nice tune up anyways.
