That means you should really not be in there messing around. If I read you correctly, you need to set voltage drop across R36 to -200v within 1/2 volt. That is more than enough voltage to mess up your whole day and completly ruin your test equipment and your HDTV if you make a mistake. Find a qualified tech to do this for you.
Now if you just gotta do this, find a good DVM and set it to the 1000v DC scale. I assume we're talking DC here. Now put the red lead on one side of R36 and the black lead on the other side of R36. The DVM should read somewhere around 200vdc, polarity is not important at this stage. Adjust if needed and back out. BE CAREFUL!
