Facing TV Problems? Ask a TV Technician.
Hello and Welcome. My name is ***** ***** I'll assist you today. I'm sorry you're having trouble with it.
10 blinks error code is bit complicated as several circuit boards in TV are involved and a proper troubleshooting process is needed to figure out bad board.
Suspected boards are SS, P, A, SC, SU, SD, K as one of them is defective, please reply back if you wish to troubleshoot the problem to proceed.
What can possibly cause 10 blinks:
A. Missing/Shorted F_15VB. Shorted Vsus volts.C. Missing/Shorted SUB5V, SUB9V, BT30V.D. IC1100, IC9003, IC9004E. Unplugged SC20, SC2 of sustain boards.F. Possibly SU and SD boards.
OK, please unplug TV power cord, remove the back cover of TV and remove connectors SS11 and SS33 from the SS board. Plug in the TV and press the power switch.
Does the TV power up and stay on?
OK, leave SS11 and SS33 unplugged. Remove connectors SC2, SC20 on the SC board. Then plug in the TV and press the power switch.
Does the number of blinks change?
Unplug the TV and reconnect connectors SS11, SS33, SC2, and SC20.
Set your mutlimeter to DC Volt range to check 15V output at pin-7 of connector P6 of power supply board.
Plug in the TV and press the power switch. Is there 15V at pin 7 of connector P6 at the moment the relay clicks ?
This is odd, have you touched meter black lead to metal frame of TV for ground and use red lead to measure volts?
No, please Do Not use brown wire of 120V AC input as reference.
Use metal frame of TV for ground and touch meter black lead there, set the meter to DC Volt range, use red lead to touch pin-7 of P6 connector to check 15V as the reading may appear on meter for a second or two when you hear relay click sound.
Also, at this test, there is no connector that is left unplugged, nor the P6 connector so make sure all connectors are plugged securely and tight that were removed.
OK, so no output of 15V that means Power Supply board is defective and should be replaced in TV to resolve the problem.
You would need to confirm the part number printed on power supply board as it would be ETX2MM747AFK or some thing similar, use that part number to search/ google to get price info to order the power supply board. I trust my input will help you out.

Hi, do you need any further assistance with this question?Thanks.
OK, no problem, take your time and reply back with the result.
Sorry to hear that. Do you get 15V at power supply board that we were checking?
Also did the board come from reputable source?
