yes, actually before post 1.

Re: Lg 60pn5000-ua

Thank you tvtimmy, did that already and got the same results.

Re: Lg 60pn5000-ua

The screen is black when the ribbon cable from the "logic board" to the main board is disconnected. When running the test the screen is black. The power does stay on while testing.

Re: Lg 60pn5000-ua

Point taken...now that we have that established, do you have any ideas drawn from your extensive experience that will help troubleshoot the problem?

@Andrew F. Ali - There is a Tcon

Dick, the flash is long (slow) short (fast) long short, it does this twice then repeats.

Re: Lg 60pn5000-ua

VS = 203.2
VA = 55.06
VSB = 115.8
VSC = 149.4
PS_On = 5.133

Re: Lg 60pn5000-ua

Yes, the Va and Vs do match what is on the label on the panel. As to pictures, there is nothing to show but a white screen. I did disconnect the ribbon cable to the mainboard and got a black screen. Jumpered R651 and R652 on the Tcon but got nothing other than the black screen I already had.

When this set was brought to me, it would not turn on. I replaced the main board and plugged the set in, it then immediately came on after the relay on the power supply clicked. There was an orange banner (please tell me what this is if you know) across the top of the screen that said something about power but due to my excitement that the set was on I ignored it and moved on to trying to change the inputs. I didn't have the remote so I was using the keypad on the left side of the set to select volume, channel, etc...each time I selected an input it highlighted and I was unable to "un"...
