Re: Sony KDL-70W850B T-CON problem
I did turn up side down the tv to see if it blinks, but nothing happend. I just see very low dim like vearly see the dim..i test them again with other advance led test and evrything work well...so my theory should be on the main...or etheir the the service menu i think there should be a backligth switch on and off maybe.Leave a comment:
