The first thing to try is to unplug the unit from the wall for about 15 minutes,if this does not work you will need the assistance of a servicer to diagnose the problem,if you are familiar with tv service you can check the horizontal output transistor for a short,sometimes it fails for no reason and other times it goes bad along with the horizontal output transformer also know as flyback.Be careful if you decide to check this yourself.

Take out the bulb (back left hatch door) look to see if the element inside the bulb is broken or blackened - (replace bulb) if the bulb looks OK then it's the ballast that fires the bulb (service call).

Likely to be the STK convergence chips causing a protection circuit to switch the TV off. Have you got any onscreen convergence problems (i.e, colour fringes)?

If it shuts off and then the power light starts blinking red or it never comes on but the power light just blinks red continuously that is usually indicative of the convergence ICs (STK 392-110). You never want to replace the ICs without also replacing the resistors that are associated with them. There are usually 6 resistors, one for each of the colors and there corresponding direction, IE Red horizontal, red vertical, blue horizontal, ect. In the case of this model tv all of the resistors are 2.2 Ohm and 2watts. You will find them right where the STK 392-110 ICs are. Right in front of them. They are blue and have this color code on them. Red, red, gold, gold. These are represented by stripes on the resistors. You can get the parts from www.bdent.com They carry the ICs and the resistors. If you do not feel comfortable completing this repair I could do it for you if you send me the board. My email address is: email@example.com The cost is 375.00 and that includes parts.
