I have a problem with my Sony KDF-46E2000. The TV is 20 mos. old and has worked well up till now. The tv will shut off and the power button will flash 43 times (it flashes 42 times and then one more time but quicker for a total of 43). Then the screen will come back on for a little less than a minute and continue the cycle all over again. The power reset did not work and it is not under warranty anymore. Does anyone have any ideas before I have to go to a repair shop.
