Samsung LN32b360 no power, no indicator

[supratkfy]

So my TV of 14 months just went out...its the samsung ln32b360. i don't have much experience in TV repair but i wanted to try since my TV isn't old and if its a cheap part maybe i can get it done. I have some experience to electrical repair. the TV stopped working completely after a power outage at my house. No red indicator light or anything.

I took out the power board for the Samsung LN32b360.

Capacitors all look ok.
I went to check diodes with my DMM. found one of the diodes had flow in both directions, while all others checked out fine. it was ZD804 on the board. if this is the problem, can i get the diode from an electronic store or would i need to order it from digikey?

any help would be great.

Sounds like you found the problem. Here is another post with the same set to confirm.

Yea I saw that thread. Now would I need to order from digi key or can I get a diode from some store like radio shack?

You should be able to find the numbers on the part and order it or an equivilent on digikey. They have a great search on their site.

So I read 1n4740 on the diode?

Looks like there's a few with 1n4740a so would it make a difference?
