Looks like it mite be a power supply.
Did the Zener blow up or was it dropped?
You mite still be able to get a number off it if you remove it from the board.
the resistor which has failed oc in the first picture died due to to a power supply blow up-which means in order to do a reliable safe repair the relevant power supply repair kit needs to be ordered and fitted.there is no shortcuts-if you just fit the parts that have failed you can see you will be wasting your time.....model number and make of set required.....
