I'm really sorry to deliver the bad news.... unfortunately there is not going to be any easy reset/fix. The tv needs diagnosis, parts, and service.
As a technician, theoretically I could help you with that but if you do not have the needed skills and tools then I would actually NOT recommend you repair a tv of this size/age due to the high cost of parts/labor and the low prices of new Tv's.
I know this isn't what you wanted to hear, but keep in mind you saved a lot of money by coming here first- typically repair shops charge $99 up front just for diagnosis (to hand you an estimate).
Despite the bad news, I hope you appreciate the answer that I provided so far. If you need more help or don't understand something use the REPLY option.
