Samsung UN60ES7150F 60" LED turns ON then OFF.

[mattpd]

I have a un60es7150f that I am trying to repair.

When you turn it on it clicks, LED flashes 5 times, the screen turns on with a VERY faint back light but no display.

It stays this way for about 5 seconds and then shuts it self off.

It then goes into a loop of trying to turn on, showing the faint back light, and then turning off. Funny thing is, it continues to do this for about 30 seconds after you unplug it.

ShopJimmy had a power supply repair kit, so I tried it. It didn't help.

I also tried a new TCON.

All voltages at the main board appear to be OK.

I'm thinking it's either the main board or maybe the LED back lights are bad...

Any idea?

Sure, when I get home.

It only contains a power board, main board and TCON.
