Samsung UN60EH6000 wont come on after lightning strike.

[karthur]

I've done some repairing. If I knew what to check and what the readings should be I might could trace down the issue. Is there a diagram or manual to show the readings?

Thanks

i always try to repair to component level, my ego collapses otherwise, depends on your repair background..

Would it be worthwhile to try to troubleshoot and find the bad part (s) or just order a replacement board?

I have already replaced the T-Con board.

Probably a faulty eprom or dc dc converter on main board

Any help would be greatly appreciated.

I replaced the T-Con board and still have the same issue.

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.

Also On P/S board I checked the voltage going out of it. There are pins 1-9 (See attached image of connector).
Pin 1 to 4 (D1+ to D1-) =170Vdc
Pin 2 to 4 (D1+ to D1-) =170Vdc
Pin 6 to 9 (D2+ to D2-) =170Vdc
Pin 6 to 9 (D2+ to D2-) =170Vdc

I also unplugged the ribbon cables between the T-CON and the front panel. With both of them unplugged, the screen is black. With only one of them plugged in, the opposite side of the screen is totally backlit. (see image below).

On T-Con board, I checked the F301 fuse and there is 12.7 volts on both sides of the fuse.

I am thinking/hoping the T-Con board is dead again. Before I order a replacement, is there something else I can check to verify this is the issue?

Thanks for all the help.
