If you have not retried it after your short resoldering jaunt, I think we can trust that it is still OK. If you made any mistakes then go to try it out, as soon as you power it up damage could be caused.
If it stayed on and didn't go into protection while losing video, that is one of the things that happens with this cold solder joint issue. I have had that happen on way more than a dozen boards, and 100% of the time my resoldering protocol has fixed it permanently.
Don't give up on it. Send that board to me, pay the money, get it fixed and don't go out and buy new, where you'll spend much, much more money and it won't last half as long as yours already has.
