Ok my tv this morning was acting up again with bad video (pic) and 6 month ago I "re-flowed" with just a heat gun (yeah yeah I know but I didn't have a heat rework station back then), and for 6 months it worked but this morning well it came back to what it was bad picture. Now I KNOW that re-flowing isn't the BEST solution to fixing this problem but I need practice with my new quick 861dw but I know that I can re-flow the chip again until the next problem (in about 6 months) but is there a "proper" way to do it so it can last a bit more time before the problem occurs again or will last about 6 months (in my case). Now what would be the best temperature/air flow should I set my quick to do a good re-flow? The first time I did it with a heat gun I didn't use any flux should I use some or just heat it? I would be willing to do a re-ball in a future time (yeah in about 6 months) so I don't think there is any stencil for tv's bga chips so I'll have to add the balls one by one and I know that the size are .45 so any suggestions on heat/air flow for this or just use the same as re-flow? BTW I have a SainSmart MINIWARE MHP30 Mini Hot Plate Soldering Preheating Station that I gor from Amazon can I use this to re-flow instead of using my Quick and if so at what temperature can I set it?. THANKS for any help with this!!!
