HI All, I have a hisense 50K23DGW that flashes the red status LED 11 times on startup. No other sign of activity.
While the LED is off or flashing (trying to start, or after it tried to startup) I get the following voltages on the PS:
12V = 12V
SW = 2.8V
STB = 3.8V
16V = 19V
While the LED is red, in Standby, I get the following voltages:
12V = 12V
SW = 0V
STB = 0V
16V = 21V
I have also tried removing the LED string from the PS, no change in behaviour. I have included some pictures of the various boards in the TV, if they are helpful at all.
Any assistance would be appreciated. I am willing to dive deep on this repair, if needed, but I'd like some guidance...are there similar models with schematics I can refer to?
Thanks in advance, Ivan
