LGTV 32LD550

This past week my LG TV just froze at the startup screen.  After doing a little research with LG, youtube, and other frustrated customers, I found that the motherboard/circuit board needed repair.  There were various repair shops that wanted my business, but the cost of fixing, the fear of being taken advantage of, and the doubt of extended life were high in my mind.  Consequently, I tried a few things on my own.

The first which seemed logical was to open up the TV and investigate the circuitry.  Now if you have never worked with hardware before then I would not recommend opening up a TV, but because I had some basic experience building a computer and teaching students how to build computers I figured I could at least open it up and look at it.  To my surprise and delight I found that the TV circuit board was in great shape with no signs of burnout.  Consequently, I decided to disconnect all the wires, push a little button that looked like a reset button, and then reconnect the TV.  Upon turning it on again, I realized that did not work.  Sad, angry, and confused, I pushed on.

I kept searching on the web for an answer.  Finally I found what I was looking for at zedic.com ( http://zedic.com/lg-42dl550-fix-repair/ ).  Zedic recommended that baking a board would resolder bad connections.  I thought it was crazy until I read all the responses and researched how other computer hardware gurus had done the same thing with their older motherboards.  It began to make sense as the connections could have cracked or had air pockets.  So as a last resort I reopened the TV, carefully removed the circuit board, wrapped it in tin foil (as not to destroy our oven), baked it following the directions at Zedic, let it cool, inserted it, and then to my surprise everything worked.  I mean it really worked.  I danced, created a rap song, and was able to use my tv again.

Now I don’t know how long it will last, but at least I did not pay an absurd fee to get it repaired and I am extending the value of my original TV which should last longer than four years.  So why am I writing about this on this website called Absolutely Learning?  Well this is exactly the type of learning that needs to happen in our schools.  We need to create problem solving opportunities.  While I am not a fan of LG TV right now for its product, I do think there is something that can be learned in this.  No this is not a good business model, but yes this is a good learning scenario for life.  Absolutely Learning lives on once again.
