Hi Guys Just bought cheap this Sharp LC-60LE741E, seller said can not get it out of standby Got it home plugged it in and it powered up, however after maybe 2 minutes it powered off itself and has not come back on since. When powering on white led at bottom centre comes on steady for about two minutes (nothing on screen) then goes off, White led then comes back on flashing three times I can not find what this flashing code is, all I am finding is 1 quick flash then 2 short flashes My Sharp TV Power Light Blinking, Mine is 3 flashes all same length Did find a reset involving think it was volume down and input held whils plugging in but that had no effect Only thing I have checked up to now is for 5V standby on powerboard which is there. My first thought is powerboard but maybe it is the mainboard When tv did first power up picture seemed good for the short time it was on Any ideas please as to what these 3 flashes are telling me thanks
