Best first step is: Good visual inspection = look for hot spots
on PCB, check caps in those areas + solder any/all bad connections,esp. low voltage regulator pins.Look the whole
board over with magnifier = solder,solder,solder...T.

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)?

Three blinks - B+ over voltage protection (OVP), unit goes to the standby mode then displays the 3 blink fault. This is also a problem in the power supply circuit, check T603 and R672.

Red power light keeps blinking and wont come on


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.
