Samsung PS-50q96HD Clicking

[anotherdude]

OK A neighbour has asked me to have a look at there TV, can here the relays clicking away constantly, can see what looks like a blow FET and some bulging CAPS.

Anyone provide any help on this, can see various repair kits for these models, is it safe to say if the FET is damaged it's taken out other components too.

Some more info, removed the power board, can see theres damage to the back of the board also right next to the damaged/blown FET, looks like the same components off the many repair kits i've seen.

common failure, cracked solders on those fets then poof. never done one but there's also a bunch of smd components too underneath hat go too. Before you get too into this I'd also check upper buffer and ymain for shorted parts. 88N30W FETS are a common one that short and the buffer ICs.

I had one from work and incredibly I had clicky, clicky blown PSU and toasted upper buffer and ymain all in one go. Bailed on that one.

Ye, thinking to give it a miss tbh, never been much good at SMD stuff.

With the BN44-00162A I upgrade to 13N50 from 11N50 and 20N50 from 18N50 on the refurbished board I sell, just to give the board more head room and always replace SMD diodes and resistors if they show signs of damage or not

Yeah believe it or not the Smd diodes were higher voltage that the originals but smaller been working for months now. Too bad I was tired when I made the video I didnt include much information.
