Default Sony XBR-55X800H Lightning damaged

The power surge came-I think- through the DSL line. TV gave a very audible pop and died. (Ethernet ports in modem were all killed too). Power light on TV was dead. I ordered a "Complete LED TV Repair Parts Kit" from shopjimmy.com and installed everything ( https://www.shopjimmy.com/sony-xbr-5...air-parts-kit/ ). TV will turn on for about 30 seconds or so then shut down. Power light flashes 7 times repeatedly. I've seen that this indicates a high voltage shutdown.? But-where is this coming from since I've replaced power supply, main board, etc.? I see that shopjimmy has a IR Remote Sensor Board for this set (this is where the power switch lives). Could this be bad? I apologize for my ignorance , my electronic knowledge extends only about as far as swapping out parts.

I’m not sure about this model. But some TVs you can unplug the ir sensor and just turn on the tv from the joystick/ button on the tv.

You may have to upgrade your software.

+1, that's what I would try first.

I can't upgrade the software because the set won't stay on long enough for that to happen.

No joy )-: I got the set to start the upgrade a few times but it always shuts itself off again after 30 seconds or so after first powering on, then starts the 7 red flashes again. If anyone has any more suggestions please let me know.

Thanks bskall, but I eventually wind up with "The described symptom may require further troubleshooting or a repair service. Please Contact the Product Support team for further support." I think it might be time to test shopjimmy's return policy and take this thing to the recycle bin.
