    Well, looks like I spoke too soon. I'm not sure what's going on with this one. I was trying to set the network back up and suddenly the picture on the screen shrunk to that of a 42" TV, then it cut off entirely and went into a loop of trying to turn on repeatedly until I unplugged it. This one has turned into a pain in my backside.

      If it's still powering up, try to access the service menu and do a complete reset, possible a small incompatibility between eeproms.

        I got the tv to turn on with that board but there was no wifi. I ordered a second main board and received it today. I installed it and now I get a 2-3 code. No +3.3v from power supply, though it will still turn on with the other board. I'm about to give up on this one.

          Seems a good deal of these mainboards are always bad, no idea why they go bad so often. My theory is someone gets angry with their faulty TV and smashes the screen, parts recycler assumes boards are good. This often appears to be wrong.

            HP EliteBook 840 G6 – no power after lightning strike
            by Bardou Kari
            Hi,
            I’m trying to fix an HP EliteBook 840 G6 that stopped working after a lightning storm.

            – Charger is OK and 19V is present at the motherboard.
            – No charging LED, no fan, no reaction.
            – I don’t see any 3.3V or 5V near the coils.
            – Battery is unplugged.
            – I’m new to board repair but can use a multimeter.

            I added a clear photo of the board.
            Any idea where to start or what to check next?
            Thanks a lot for your help!...

            Panasonic TH-50PX80 killed by lightning strike, help me save her!
            by SluggerB
            Yes it's a 17 year old Panasonic plasma!

            I was watching TV when there was a huge lighting strike nearby my house that shook the house. When that happened, the picture on the TV froze and the TV wouldn't turn off except by pulling the power cable. Now if you plug in the TV, it seems to turn on (it makes the turn on "clikcs" it always does, the red power light comes on but there is no picture, although I can see the back light around the edges. And the TV doesn't respond to the power button on the remote to turn off, and doesn't respond to the manual power button on the front...

            Samsung UN60EH6000 wont come on after lightning strike.
            by karthur
            We had a lightning strike a few days ago really close to my house. My Samsung UN60EH6000 was on when it hit. Afterwards, the TV would not come back on.

            I had repaired this TV a few years back by replacing the T-Con board. (The post I had on this is repair is here.)

            When I turn on the TV, I don't get any start-up melody. The screen just dimly flickers around the edges.

            Here is what I have checked.
            On the power supply board, 14pin connector:
            1 :12.7 Vdc
            3 :12.7
            5 :12.7
            7 :12.7
            9 :0
            11 :5.
            13 :5....

            advices for repairing Sony Bravia 32EX600 after lightning strike
            by pbig
            hi everyone,
            my parents in law have seen their Bravia Sony LED 32EX600 TV set stop after a lightning strike. After being plugged to mains, it shows nothing no power LED on bottom left shines.
            On the power PCB (GE3b, attached pic), I chacked the fuses and the only roasted one is R6536 : 0.47 ohms, 1/2W. After replacing it, I made some voltage measurement with ref to the chassis :
            - the 450V/150uF capacitor voltage when plugged is normal at 394V
            - from connector CN6150 (15 poles)
            STBY normal 3.3V -> I shunted it to 3 (POWER ON) and 11 (BL ON) and unplugged...
