First, try the unplug it, wait a few minutes, plug it in trick, several
times. If that doesn't work try pressing the power button and slap the
back left side of the set several times. Sometimes, this will shock the
ballast and/or lamp into working.
Try checking the wires as well if its pinch or not and try to take out all cables from other devices from the back

If you have a service manual, please match the voltages as per that and problems might be in areas where these do not match. But read on what condition these voltages are to be checked, this is usually written in a service manual, i.e, without any signal or feeding some signal etc.
