My son uses this heater in his room and my husband shut it off one day. My son then tried to turn it back on later in the day and it wouldn't heat up. The power light just keeps blinking.

there's no reset, but unscrew the 3 screws in the back. Cut out white sleeve that covers the red & white wires. Take the fuse out from beginning to end. Attach the white & red wires directly. The fuse is not needed. Wrap w/ electrical tape. You, me and everyone that has bought this heater had the same problem. I called customer support. This is what they told me.

Occassionally a surge may disrupt the power supply. Unplug the power cord, wait a minute or so, and reconnect. This will reset unit in most instances.

the pilot's millivolt generator may be at fault. if you have a meter that is capable of measuring a very small DC voltage, connect it up to the very end of the thermocouple and the copper cappillary. the thermocouple has a welded bead at the very end inside that generates a small DC voltage. Same principle of a J-K thermocouple. Iron constintan - two dissimiller metals where joined together produce a voltage when heated. the thermocouple actuates a millivolt electromagnet inside the valve to keep the valve pellet open. no voltage there it won't actuate the electromagnet.

If your set was manufactured around July 2005, you may need a firmware upgrade to solve this issue. On the Sony website you can enter your model # and serial # to see if you TV is affected. If so, it is easy to have done and may be free from Sony. It sounds like the issue they described in the writeup on the required formware update. I had mine done within few months of when i bought it (purchased in Dec 2005) and it has been working flawlessly since.
Good luck!

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)?
