This op I know bought a few WG7401's back at the end from WG(they are tagged 10/07). 2 have gone into shutdown recently. I recapped 2 of them( I just heard the 1st one I capped 2 months ago is down again, 2nd one I just capped an put into #3 today).

Now a 3rd has failed, but its collapsed down to about 1". I am going to recap it too, You think caps will bring this one back or is it probably something else?
 
Maybe, but you need to do that first anyway to be sure. Then you can diagnose knowing caps aren't the issue (unless you're using crappy caps)...
 
using a zanen kits. I think 2 or 3 caps did not match up. I used esr to confirm the old ones were good and reused them. I fired it up and its fine now.

Just to note it as it may help someone, I did not not reflow any of the remote pins. Just the usual (flyback, neckboard and video cable). The traces lift off pretty easy on this board. I messed one up and had to fix it.

Going to go swap this one with the one that failed. Will see whats up with that one.
