5 times flashing power light indicates problem with t-con board and when you install different t-con board the main board doesn't recognize it and at this point you would need to update TV firmware to establish communication link between t-con and main board. You would need a USB memory stick to download and copy firmware update file and plug it in USB port of TV then turn On the TV and update will begin itself, it doesn't matter if nothing appears on screen, give it 15-20 minutes to finish the firmware update process and TV will turn Off itself. Unplug USB memory stick from TV and turn On the TV to see if it works, you can download firmware update file from following Sony link..

Please note that above solution is for 5 blinks error code only and isn't related to "solarization" issue which happens due to either defective t-con board or internal circuitry of display panel (the screen).

I trust my input will help you out. Please feel free to respond if you have any additional questions.

You're welcome, copy the firmware file on USB thumb drive as per Sony instructions mentioned on that page so TV can get correct file to boot up and start updating.

Please feel free to respond if you have any additional questions.

Thanks.
