Re: IC Number on DPS-286 AP/RDENCA336WJQZ Sharp power board

Hi, I have Sharp LC-42A66M and having intermittent power off problem. TV will shut off of a few seconds[no green/red light at front LED] and it came back. It happens once/twice a day. And, sometimes no problem for a few days.
I though it was bad cap and opened up and checked the power supply board.
But, there was no bloated cap on board.
Power supply board is DPS-226AP-1 (RDENCA340WJQZ)
Is it possible that TNY264AP is having intermittent issue?
Should I just replace it?
Thanks in advance....
