Re: vizio gv42l-hdtv 3642-0012-0150
I replaced the mainboard with the one i got from ebay ,now when i turn it on,the screen lights up blue,and says NO SIGNAL, stays on for a few seconds and shuts off ,you can hear sort of a humming sound on the power supply board,after a little while a click,at that point you can turn the set back on,and it does i all over again . Any ideas,thanks.Last edited by armdole; 04-16-2015, 02:54 AM.Leave a comment:
