Re: UN60F7100AFXZA issue standby blinks 5x never turns on
would there be any parts to check on the main board for replacement or easier to just get a replacement. and would not having that signal keep the power relay cycling?Leave a comment:

Re: UN60F7100AFXZA issue standby blinks 5x never turns on
I have attached voltages I got from the main board side connector with all boards connected and TV plugged in then also while the power would cycle. I do not see anything on the screen when the power is cycling even with flashlight...Leave a comment:

Re: UN60F7100AFXZA issue standby blinks 5x never turns on
I went back over the power supply board this morning, and disconnected it from the main board and plugged the led cables back up and the lamps power up when plugged in. also when the main board is unplugged all the pin outs show the voltages they call for on the board,
1. 12.6
2. 12.6
3. 12.6
4. 3.1
5. 1.35
6. 3.1
7. 1.35
8. 3.1
9. 0
10. 3.1
11. 12.6
12. 3.1
13. 12.6
14. 12.6

Re: UN60F7100AFXZA issue standby blinks 5x never turns on
TV model : UN60F7100AFXZA
POWER Supply Board: BNN-00630A
from what I can see pin 22 A5V it is the only pin that is carrying voltage before I try and turn the TV on

Standby pin 22 holds 5.34 V steady throughout
PS-ON PIN 24 is 0.26V in standby mode
PS-ON PIN 24 3.3V when relay closes,
PS-ON PIN 24 0.26V when relay clicks back out
What would you suggest to look at why the main board is...Leave a comment:

Re: can anyone help me identify this cap
its from samsung tv, the power relay keeps clicking on wait 5-10 secs but it never powers up the tv. this cap will carry 5V then discharge with the relay. but the tv never turns on it just keeps power cycling. the caps all appear in good working order show readings of or above their rating.Leave a comment:

UN60F7100AFXZA issue standby blinks 5x never turns on
I have a Samsung UN60F7100AFXZA it is just clicking and not turning on fully, the standby light blinks 5 times then the power relay clicks and starts the whole process over. I get steady 5VDC on pin 22(I believe to be the stby) on the cable that connects the logic board. the other pins match the board markings when I try to turn the tv on. the power relay carries 5V when closed on the small legs, the capacitors appear ok and read at or above rated capacitance except for the one circled on power board image, which will show as a short then 70microF. Not sure what the capacitor is cannot find any... -

I read whats on the cap but it doesn't list any capacitance but it acts like it wants to keep discharging repeatedly unlike the other capacitorsRe: can anyone help me identify this...her capacitorsRe: can anyone help me identify this cap
