Hello, my name is ***** ***** I'll assist you. I need additional info to troubleshoot the issue.

The main power board is a there a high temp link on the transformer
Expert:  Shahid replied 1 year ago.

OK, following are possible cause of 10 blinks error code..

A. Missing/Shorted F_15V.
B. Shorted Vsus volts.
C. Missing/Shorted SUB5V, SUB9V, BT30V.
D. Possibly SU and SD boards defective.

E. A or P boards defective.

Now unplug the TV power cord. Measure the resistance between pin 1 of P2/SS2 board or P11/SS11 board (Vsus) and ground.

Is there a short circuit or you get low/zero ohms reading?

We need to know where on the schematic the p2 and p11 boards are...our boards have, su, sd2, c1, c2 and ss
Expert:  Shahid replied 1 year ago.

pin 1 of P2/SS2 or P11/SS11 are connector numbers of SC and SS board.

Customer: replied 1 year ago.
Those numbers are not on our boards...can you send photo of schematic pointing it out?
Expert:  Shahid replied 1 year ago.

Please find 3 attached pictures where connectors are marked with red arrow.

Customer: replied 1 year ago.
Ok so found pin 1 of p2 and p11...board is disconnected and out of pin 3 the ground?..or what do I ground to?
Expert:  Shahid replied 1 year ago.

Please use metal frame/ chassis of TV if board is still mounted and if board is removed then use board ground pin that would be next pin of connector.
