A 0.068 reading zero is not uncommon. Most ohmmeters do not measure that low. Suffice it to say it is not open, and it is very unlikely to short.

Before changing tht IC, you must find and fix any shorts on the secondary side of the transformer and identify the output pin. It will go straight to the transformers and may have either a cutout around it in the board or a coating of white **** on the board.

Whichever it is, if nothing go with the ohmmeter from the top (+ probably) and find a pin that checks pretty much continuity to that gong to the transformer. Now look around, there will be a diode, resistor and a cap Make sure those components are not open and as they are voltage snubbers without them the IC is destroyed fast.
