My TV shows no picture at all, When I try to turn it on I hear some clicks and then I get four red blinking lights code, I have searched for a service manual for this model, but I can't find one.
I think I can test and replace boards myself (with some guidance) if I know which one is faulty.
Thank you all in advance.

After a bit of hunting I found the service manual for my model TV.

I followed this troubleshooting diagram for the 4x blinking code, but I am getting different results with voltage readings when the TV is booting up, or TV on but blinking 4 times, or off in standby mode.
+
+
In other words I get the 3.3V or the 0V at both testing points at different power states of the TV.
+
+
So my question is, when am I supposed to be reading these voltages?
+
+
While it is booting up, after is has booted and is blinking the code, or plugged in but off in standby mode?
