Re: Sony KDL 55HX800 Lightning-HDMI's bad
Applied firmware and after about 3rd try with lights still blinking green/amber, took a few minute break. On return, the update was surprisingly showing complete and all HDMI inputs now working.
Helpful video from Nick's TV Repair....

Re: Kdl-70w850b Possible Lightning Strike
Thanks but I would not know if it is the same for my TV....KDL-55HX800.

Re: Kdl-70w850b Possible Lightning Strike
Had same thing happen a few weeks back. Fortunately via assistance from this forum and other online assistant/Youtubes, my problem was main board but only the HDMI inputs. Was able to score a Main board from a TV repair guy in Houston and am awaiting a usb he is mailing me with Firmware update since Sony Terminated updates for my model Jan this year.

Received a Main Board replacement purchased from Davids TV repair in Houston TX.
After installing, rcvd green and amber blinking lights which supposedly denotes needing firmware update. Sony terminated my model updates Jan this year. TV repair guy thru his contacts is sending me Firmware update via USB. Will update further after applying update.Leave a comment:

Re: Sony KDL 55HX800 Lightning-HDMI's bad
Have no clue what you're talking about. I bought nothing that was a [I]"defect"[/I]. The Main board on the subject TV got hit by lightning and trashed the HDMI inputs. We have since bought new TV but want to try and fix bad TV to use upstairs. Perhaps your simply misunderstanding the problem or simply not reading what whole problem is.Re: Sony KDL 55HX800 Lightning-HDMI's bad

Sony KDL 55HX800 Lightning-HDMI's bad
Hello,
Last week our home was hit hard by lightning, so much so that 4 transformers on our street were blown out.
Items lost....DirecTV box, Cable TV box and initially Sony 55"....all inputs hooked up via HDMI. We have since purchased new set but wanted to at least try and see if this TV can be fixed.
Initially while T/S, found all inputs fine except [B]T-Con_ON = 0VDC[/B]
but front panel had 3 red blinks. Yesterday took Pwr Supply and Main Board out to check for any noticeable failures. Coincident or not, after replacing both boards the TV started working... -

Hello,
I hail from the Volunteer State. Having just joined, I'll be searching the forums in hopes of
