@aquamon:

Whoa! Whoa! Whoa!

Hold yer Horses!

This is the Inverter Board!!!

Look at the FET just by those swollen Caps...SAVE your money.

Change those 3 Caps AND that FET (test at least), let's go, already!

I still see a FET...

That's the FET I was asking you about!

I already said there was a FET driving each of the backlight inverter transformers:

I can see one so8 pkg on the primary side of the smps section, I assume a PWM switching controller (IC1), driving the primary side switching FET (TO220 pkg). There's also an 8 pin FET package driving each of the backlight inverter transformers. The only cap (other than the main reservoir) that I can see on the primary side is the small green one which smooths the bias supply to the PWM IC. I can't see any FET associated with the blown secondary side caps.

Again, I was asking you where the FET associated with the failed capacitors was! I couldn't see it, still can't. :-//

Sorry, here's an example:
http://pdf1.alldatasheet.com/datasheet-pdf/view/248610/RENESAS/HAT2215R.html

I don't "see it" either, just experience.

Yes, I know what a FET looks like too, I've designed in plenty. In fact I can see three of them on the board, two SO8 pkg and a TO220 pkg, just not the one you "don't see" now.

If you can't see it either and you can't explain what function it would be performing in the circuit if it was there, then there really isn't any more to be said, is there?  ;)

I've already indicated that there's no more to be said, by me anyway.

WTF are you talking about???  :-//

You come to this thread, which was already providing the OP with all the help he needed, with your:

... and then keep going on about some mythical non-existent FET, even posting a link to what a FET looks like FFS  :palm:

I see you are also trolling the Westinghouse... thread, and the DL209L equivalent threads too!  :palm:

You are being reported, trolls are not welcome or knowingly fed here!

That's the point, only to yourself.

Anyway, if you really care to know, look at its LOCATION - and there are TWO.
 :=\
Just LOL.
First you were seeing and suggesting replacing the FET besides swollen capacitors. When proven there is none, suddenly your memory became short of that. Now keeping your point by saying there are FETs in other places on this board. What a freaking discovery, CCFL inverter which is using MOSFETS  :-DD. There are 3 MOSFETS on this board (two of them 2x in one package), none of them in the secondary side of the PSU, where swollen caps are located.
