I know this has been talked about before but i got my 4dtv receiver back from my uncle and the receiver is about 7 years old but has been sitting unplugged for about a year from what my uncle told me, i haven't checked the unit id yet but was looking at the factory sanyo lithium battery inside and it looks like it's only being held by 2 prongs to wich the battery would slide out of unless it's sodiered in,this 4dtv is the latest version and was wondering if anybody has info about changing it or who i could have do it.
