Have a RCA LE65G55-A404744 standby light comes on when you plug it in but when you push the power button the LED back lights flash one time but nothing powers on. Checked the power board at the 5 volt prong and it is reading 10.4 what could cause this issue

Hi, If all else fails, try do a hard reset. You can verify from your manual, but in some units, this is merely unplugging the unit from mains for a couple of hours. Try again, if it still shows error codes (blinking lights) you probably have to seek the services of a qualified professional. Hope this be of some help/idea. Good luck and kind regards.

One of the boards (module) has a short on it, and or the power supply itself is failing.
The service center will find the fault using the process if elimination. They will replace the bad boards or modules as required to get the set working again.
