Samsung TV - UN58H5202AF - No Power

[@tomatoplot]

Nice work! It's crazy to think about how many TV sets like this get tossed only because a tiny component went bad...

Well done repair

Thank you for shering Ray:)

great repair

[@crashoverride328]

Nice, but a suggestion. Always test the MOSFET out of circuit too, yes it shows a short in circuit, and normally it is the source of the short, but it's worth spending the 10 seconds to test it out of circuit or at least confirm the short is gone when it's removed. Nice to show on camera too as validation of the diagnosis. I suspect you do this anyway but it's helpful to show it on camera for those new to repair.

Thanks for the feedback.

Can you please share the link of new MOSFET purchase? DigiKey's link with MOSFET model?

[@306arts9]

Instead of replacing the component can I just replace the whole board?

[@raysrepairsottawa]

Yeah, if you can get the whole board it will be easier.

Have a link or product number from Digikey?

I've replaced these and usually they fail when the LEDs in the TV start failing short. Make sure to fix the LEDs in the tv set too, it looks like a couple have failed short which stresses the power supply.
