Greetings th674 and welcome to the Forum !
What I am about to tell you, may put you in a position to receive an Electrical Discharge from the set. But, with reasonable caution, you can avoid this.
Make sure that the set is unplugged and remove the housing cover which is most closely related to where the Power Cord enters the set. Don't touch anything other than that right now, we're just looking at this point.
With good light (flashlight maybe) find where the main Power Cord enters, and follow it along it's route. What we're looking for now, is a Ceramic/Glass Fuse which you may remove carefully, and test it with your meter, on the Ohms scale.
I am not totally familiar with this particular model, but many have such fuses, and it would be the simplest thing for you to do yourself. There may be others as well, which may keep the set from powering up, and those may be checked as well.
Just remember, even when the set is unplugged, stored voltage is present in several places therein, and you must be careful. You could use some Gloves if you wish, but, if the Fuse is deep in a congested place, I'd say pass it up, and foot the bill for some professional repair.
Should you find a blown Fuse, replace it with an Identically Rated replacement, but, i strongly suspect that there may be additional damage to other compontnts, which you may not be qualified to diagnose or replace.
You ask for something you could do yourself, and I'm sorry that it's so little. Someone who has had some more direct experience with this model, may reply here with additional information.
Good Luck !
Have a good Day !
S.W.
