l337 soldering skills

I totally forgot. So my mom has had this TV since i was in high school, which was more than 10 years ago. but the thing is, it is a 65 inch TV and replacing it is less than appealing, especially during this consumer holiday “season”

The TV has an issue. This happens to be a pretty well documented issue for this TV. The issue is that its got some convergence issue. The red and blue  (or some say green) shadows are showing on opposite sides. so the left had red shadow and the right had blue. The solution? turns out it just needs a re-solder. the IC’s that control convergence get cold joints and then start to suck.

the previous fix that I had put into place during the thanksgiving holiday was I put a piece of hanger on the heat sink pushing, and pulling it (2 different times) into a place where it works. This is fine and dandy for a 2 minute fix but should definitely not be done long term as it just exacerbates the actual issue.

so yesterday i took the TV apart with my little bro and we re-soldered the IC responsible. it has been running all night last night and today and now tonight and it is good still.

Now i know what your thinking, why didn’t i do this first, well i didn’t have a soldering iron at thanksgiving. and also the hanger fix worked for days at a time.

long story short, her Mitsubishi might be fixed for a while (until it needs re-soldered again) or it might be a multi-day or multi-week fix. Sure she still needs a new TV, but to replace a 65″ TV would cost over 1500 bucks that just didn’t need to be spent right now.

I guess that says a lot about me because my TV was a used TV purchased for cheap because it had some over heating issues… and it works now with just a little heating help. lets hope it continues to work for a while because i don’t want to buy a new one or a new bulb right now and would rather just not have a TV if it goes out.

oh, and my seeed studio order shipped so my Sparkfun button pad should be up and running soon (6-14 days, Hong Kong post shipping time frame)
