Odd symptoms here.
When I plug in the set, we get a solid white light and no response from any of the buttons either on the set or from the remote.
Now after a couple minutes of being plugged in, the set will go into the 1 fast 3 slow blinking code. I tried forcing the set on, but all it does is go back into the blinking error code.
Now I have seen off other threads and youtube video that this code directs you to a bad Power supply. However I have a known good power supply I took out of this same model TV a few weeks back that had a bad panel. Same error code.
Now I did go ahead and disconnect the power supply from all boards and proceeded to short PS-on to 5v standby and got the 13 volts to turn on. Did the same with the panel on and was able to get all voltages to appear properly out of the power supply except for the LED's. Could not get those to light up. Output voltage would not go above 77 volts with the leds connected and disconnected.
took out all the jumpers and reconnected everything back up. This time disconnected the right ribbon from the T-con board to the panel and powered up the set. When I did this, the led strip still did not come on, however not only did I get the sharp logo on the left side of the screen, but the voltage was able to climb up to 144 volts output to the LED's regardless of them being connected and disconnected. They never did light up or flash even when forcing the tv and would only stay at 144v for a second or two before going back down. But at least now the voltage climbed up to 144. Now after this happened, the tv went into a 1 fast 1 slow blinking code. This usually means bad LED strips. So does this mean the main board got confused due to half of the panel being disconnected and showed the wrong blinking code, or do I have a bad panel and bad LED's? I super don't want to take the LED strips out if I don't have to for obvious labor intensive reasons but if need be I can fix them no problem
Please advise.
Thank you
