Just moved. Won't power on. Red standby light blinks.


Needs recalibration... is all I can tell you without actually physically being there to fix it.. The Tv gots what they call "guns" and when they are thrown out of wach they need recalibration you can take it to your local tv repair shop and have them do it..

Good day,

Your problem indicates that there is an issue with the horizontal or vertical circuitry. Some parts may have been busted thats why your tv cant function normally.
I suggest you have it checked by a repairman,

Response is highly appreciated.
