Yeah I looked at that other one, its older design I think and its not got the best of enclosures, but the killer for me was that when I checked the actual size, it was to ffing wide

Put it on your med's cart under the 7904. It's probably one of the few MEBBs out there that can actually handle the weight, and all its heat-sinks hang off the back, so thermals should not be a problem.
Also, then you'd get to be a decent bloke covering for one of your mates having a little brain-fart. ![Tongue :P](https://www.eevblog.com/forum/Smileys/default/tongue.gif)

Gee, don't think Specmaster has a 7904...at least he never mentioned one. I have one and so does Oculus. Do you need more caffeine to unscramble your brain? ![Laughing :-DD](https://www.eevblog.com/forum/Smileys/default/smiley_laughing.gif)
D'OH! That was
your 7904/cart.

All fixed now.
Seriously, this effing TV power supply has me

... reviewed oodles of fix scenarios on the usual repair forums, even did the full "factory fix kit"... but it still goes into shutdown after 2-10 minutes and stays that way until it gets cold-cold. Can't find anything getting warm, can't find any rails gone short, all caps in question test well within spec. So far, nothing seems to be drawing excessive current, and I can't detect any signal on the various PROTECT lines, even though they're documented on the board.
Worse... as I go through the schematic, every component I check already has a Sharpie hash on it in red, green, black or blue according to the rail they're on. Somebody (possessed of a reasonably sensible method of attack) has suffered this misery before me.

I just KNOW it's something EFFING STUPID I'm overlooking or just don't have access to full documentation. I have several different issues of the FSM, but it only covers the PSU and a regulator sub-board directly after it to component level. Nothing on the logic, processor, BL inverters or INPUT/TUNER boards; and the diag procedures in it only go down to board level. Also pretty much ZERO info on theory of operation on the PSU/protection feedback circuitry.
It’s all the Poutine ![Laughing :-DD](https://www.eevblog.com/forum/Smileys/default/smiley_laughing.gif)
That actually looks appealing....I'll have to try it. ![ThumbsUp :-+](https://www.eevblog.com/forum/Smileys/default/icon_smile_thumbsup.gif)
I've not tried a genuine Canadian one.
I haven't tried it yet, either. Perhaps on my next trip up north. Gotta get me some Coffee Crisp and maple sandwich cookies, too. ![Azn ^-^](https://www.eevblog.com/forum/Smileys/default/azn.gif)
I've been in several eateries that have it on the menu... been very tempted to try it. But so far, the dumb blank stares I get when I ask what's in it have severely put me off. Not sure about the Coffee Crisp & maple cookies... they sound yummy though.
Kosmic or 25CPS, can you chime in with some common national brands that are known to be good examples or at least edible...?mnem
