I would like to down load the TV manual for my bush TV the serial num is 5635 948-400429

The only on-line manual link I have is the one of Sears "Manage my home".
Try this Sears on-line website and see if your TV is found there. Your serial number is of no use : you need the Brand (= Bush) and the TYPE number of the set to get a manual!

Good luck !
