How to find out the exact model of resistor when it's not clear?
When trying to repair a TV, you can usually find a repair manual online. The first thing to do is to type in the model of the TV with "service manual" or "repair manual" and see what you get (being careful, some of those sites are spam/virus related). 

I was able to find your repair manual here: Manualslib.com: Hitachi C43FD2000. 

Schematics of the boards start on page 23, but if you go to page 126, you'll see a parts list:



It doesn't really help much since it doesn't have the value there, but if you look at the schematic on page 29, you can find RK45/46:



So these are 1S-3R3JB, 3.3 Ohm 1-watt resistors. The specific model is available on Mouser (although it says 1/2 watt), however there is no stock. You should be able to replace them with any 3.3 Ohm, 5% 1-Watt resistor (should try to get Metal Oxide ones, like this one).

Before you go pulling apart your TV though, take a look at the calibration procedures on page 66, you may be able to adjust out the distortion.

The resistor bands should be Orange-Orange-Gold-Gold:
