The blinking red light is not just a fuse issue. The fuse needs replacing, yes, but because of a gap issue on the board. See this tech bulletin: http://tacpservice.toshiba.com/TACP/subpages/pdfs/TechBulletins_TV2002.pdf
If not repaired properly it could cause heat/fire issue according to one knowledgable poster. As well, the yoke may need replacing.
If you repairman doesn't know this, use another repair center. I have the 42H81 as well. I'm on the fence about repairing...not sure it is worth the $4-500.
