Advice on (hopefully) simple repair to RCA HDTV

[YamahaFreak]

Yep, I've done it again! Second curbside TV in a month. This one is a 2004 RCA (Thompson) 52" HD rear projector. The guy said it quit working about a week ago. I get it home(inquire about sidesplitting story!)and plug it in. The standby LED lights up and the power supply energizes, but the set doesn't turn on. I remove the back panel and find a thoroughly toasted resistor on the back of the mainboard, well away from the PSU. The carnage on the board roasted off most of the part #, but judging by the others on the board, I think it is number R14703. The rest of the board is clean. Pics:

Also, in the first pic, you can see on the screen what looks like shadowy arches; I don't know if this is a burn or other damage to the screen, or just a reflection. It's only noticeable from some angles under certain lighting. Hoping to get this working to go in our pool room for Super Bowl and gaming.
