The backlight illuminates and stays on.Then, I removed power from the TV, reconnected CNM803 at the power supply and disconnected the LVDS cable at the main board and re-applied power. The backlight illuminates and stays on, and the standby LED blinks 5 times, then goes dark.At this point I believe I have it narrowed down to either the TCON or Main board. I need further guidance on narrowing it down to one of the two.

Hello my name is ***** ***** I'm happy to assist you with your TV issue. You did the perfect troubleshooting sequence to illuminate the power supply and backlight. Since you reconnected the power supply with the Main board and the backlight stayed on, it is safe to say that the TCON board had an issue. There should be a 12v line from the Main board going to the TCON board. Double check that it is present. But yes I would replace the TCON board.
Ask Your Own TV Question
The TCON board has the part number BN95-01337A
Just for info the Main board has part number BN94-08192E or BN94-08061B

I also attached for you some troubleshooting material and wiring diagram info. Page 3 on troubleshooting material shows to check for the 12v Tcon.

The price of the TCON board is $101 at www.encompass.com

At www.shopjimmy.com (another reputable online parts vendor) the price is $60 but out of stock

Hi Martin,Thanks for the response. I'll review the information you sent and see if there are any further questions before closing this out.You mentioned "There should be a 12v line from the Main board going to the TCON board". Is this carried on the LVDS cable between the TCON and main? Otherwise, there is a six wire connector on the TCON (CN600) that goes back to the power supply connector CNM803Thanks,Joe

Hello Sir. You can measure the 13v at Fuse F1 on the TCON board which is the B13 line. In addition the voltage comes from the lvds cable connection CN1401 pins 47-51, and BD1 on the TCON board for panel 12v.
