As long as the tv is not unplugged it should stay on the same channel when turned back on. If you have the tv plugged into the cable box, when the box is shut off it basically unplugs your tv and the tvs memory is reset. The tv should be plugged in to its own outlet or leave the cable box on and turn off the tv. If you turn everything on, cable box and tv, and have a picture, go into the tv menu and auto program the channels, it should only lock in on channel 4 since it will be the only channel the tv will receive.

It sounds like you may have blown caps on your power board. This is quite common with LCDs. Though it could truely be a number of other things. Best thing to do is take it to a repair shop if you arent electronic savvy. If you feel comfortable taking it apart look for circular caps that are bulged on your power board.[the one that the power plugs into or immediantly runs to...usually brown] IF this is not your issue you may have a short somewhere.
Please take a moment to rate :] Thanks!

If only power button is blinking then there is a problem only in your power button tube.
This sounds like a problem with the reset in the TV. This is not a reset circuit like you are thinking. It has to do with the micro and relay circuit in the TV. Another way around it would be if you had a cable box. You could hook it up to the cable box and just shut off the box and this would turn off the TV.
Also Unplug the TV and wait for a few minutes....plug back in. Hopefully it'll reset itself. If not, try reprogramming the remote and use that making sure there are good batteries in it.
If nothing works pull the back off and look around for a fuse near where the power cord is connected. It may be a circuit breaker too. Locate but DON'T TOUCH the large black wire going into the side of the tube. Follow it back to the fly back transformer or voltage Tripler. Look for a fuse here on the circuit board. Reason I say don't touch the wire is that it could be charged at about 28,000 volts which is normal for a colour TV. The TV glass and the outer coating forms a capacitor which stores DC current. An open fuse would mean the power supply is not functioning.
Please get back to us if you have any further query or else accept the solution.
