Re: Sharp LC60E79u 2 blinks power/3 Blinks OPC
Budm, you referenced in the earlier post to "Also read this thread for 2:3 blink code: https://www.badcaps.net/forum/showthread...harp+LC-60E79U." Would it be appropriate to take reading on the MOSFET q7120. RebRebel10 use a 330 ohm resister in trying to troubleshoot the Gate issue.

Re: Sharp LC60E79u 2 blinks power/3 Blinks OPC
Budm, I am so sorry I made a measurement error. After making measurements from the bottom of the Power Board S14.3 is present at the bottom solder with a reading of 14.3V.
However when I try to measure from top of board pin connector with a small probe inserted into the where the S13.3 cable connects, there is no voltage present. I wonder if I have a bad cable?
I also measured voltage on Main Board at PD (top of cable and at the pins connected to the board) and the following voltages were detected:

"Are you 100% sure that S14.3V is not present? This Voltage is from the same out put of the power supply that produces the UR14.4V, you can see how the connections on the bottom side of the board."
OK, I checked the S14.3V again and there is no voltage present. I'm attaching pics of the of the whole backside of the TV showing all boards and the bottom view of the Power Board.

I will check readings again tomorrow take more pictures.

Sharp LC60E79u 2 blinks power/3 Blinks OPC
I have a Sharp LC-60E79U with the blinking light error (Power and OPC blink 2 times together then OPC blinks 1 time. I read the previous thread on Sharp lc60e79u ([url]https://www.badcaps.net/forum/showthread.php?t=66913&page=3[/url]) with this same issue, but no resolution was posted.
The service manual indicates this as a “DET_5V (33pin) error (L). 5V is not applied.”
I cannot enter service mode by pressing input and channel down and plugging the unit in to power outlet. However, I can override and enter the diagnostic mode if press channel down and volume... -
Re: Sharp LC-60E79U - 2 Green, 1 blink - 1 Green 1 blink
I'm getting the same blinking light error. Did you find out what part on the main generated the Det_6V failure?

Re: Airis lcd monitor m143b
I found the same bad transformer (an IPT-1820-A-GP) on my Toshiba LCD on board IVA-1904A. Anyone know of a USA source for a replacement transformer? Internet search resulted in the board "sold out" or out of stock at many sites.
Thanks,
