The power went out, and when it came back, my t.v. had a black screen. The power on the t.v. looks like it's one. There is a red blinking lite on the bottom of the t.v.

Repairing Flat Screen TV - Blacked out with blinking red light ...Capacitors are little cylinders with a flat top with an X. If they have failed the X .... picture, no sound, totally black just the red power light blinking on the corner ... hello i have a dynex dx-lcd42-09 the red light blinks as soon as i plug it in i opened ...Missing: 5x
the light indicates an internal electronic fault with your set projection TV`s have integrated protection circuits built into the circuit design, these circuits turn the power off automatically when a fault has bin detected this is in order to prevent a more costly repair, these circuits monitor power supply , vertical and horizontal deflection over voltage, or x ray, and also faults with convergence circuits. Diagnosing these faults require test equipment and a good knowledge of electronic repair techniques, and also a repair manual.
I am working on one right now with a similiar problem. The power supply is bad in the one I am working on, and sadly, the part is not made anymore. I hope you have better luck than I am finding the bad component in yours. Sorry for the negitive answer.
