Sony KP-53HS30 TV Solder Repair

*Please use caution working on any TV as the high Voltages inside could injure you*
I am attempting to repair a friends TV, it has been working great but lately something makes the video go off but the power and audio stays on. I am thinking that there are a few solder joints that are broken so I am re-flowing the solder to those connections to see if that is causing the issue with his TV. Note: A broken solder joint will connect when its cold, but as the heat rises in the unit, the solder joint expands and causes intermittent issues.
This is not a complete repair video, just a solder guide to use for your own repairs.
