Well, somehow my dad got ahold of a broken HDTV from a friend that would have ended up in a dumpster, and I have been asked to attempt to repair it.
While figeting with the power button to try and see if it was just the lamp that went out with a flashlight I was able to get it to turn on once. From there, it seemed as if everything was fine. I tested most of the video/audio inputs and it seemed as if nothing was wrong
Finally came the point to turn if off and see if it would come on again......it didn't
Because of how irratic it was being, I've tested and fixed a few cold solder points on the main board, the board with all of the input switches on it, and the board that has the green power light/IR receiver. This didn't change anything. I have yet to test the internal power supply and one more board attached to the actual LCD screen for cold solder points.
In the case that more cold solder points aren't the problem, what are some common components that go out in these and where would the general area be to find them?
the thing did come from a bar, so it was mostlikely on almost 24-7
