How many of you fix your own TVs?

But you have to understand that a lot of people would be afraid to take the back off of the TV even if they could figure out how to do it, and wouldn't know a power supply from a threshing machine. Nor what its purpose in life is. To a lot of people all technology is "black magic". They don't have a clue how anything works, and really don't even want to know.

Yep... everything stops when the smoke gets out...

We have a TV in our room that I picked up for free along the side of the road, it didn't want to stay on, would flicker on and off. Replaced the power supply board with one off of eBay for 30 bucks and it's been good for a year and a half now.

That could be a simple as a bad solder joint on the power supply.

I have found those by puting it in a dark room and carefully tapping the power supply board with a piece of wood, while the TV is on. You can see tiny spark where the bad joint is, as it makes and breaks the connection.

That's because all electronics run on smoke. BUT it is supposed to be a closed system the smoke is just recycled thru the system. When something goes wrong, the smoke is released and that is the end of normal operation. It is very difficult to get the system sealed back up and new smoke put back in to get things going again.

I don't remember exactly what was up with it, but at least one of the components on the board had lost its magic smoke.
It was simpler to just pick up a new board on eBay.
