Re: vizio M470vse power board?
Ok My appologise. I used a different DVM and it seems as if 12v on cn101 and 25v on cn202 are good now. I checked again even with another DVM after that and the DCV read good on both connectors. Now it seems as if power board is ok. Double checked grounds and reference 3v all good. HMMMMM?????

Sorry about delay. Have been stupid busy. Here is the pic of the reverse side of that power board. The upper right at those batch of resistors, it looks as if it has gotten hot. But they all have tested good. ...

vizio M470vse power board?
Hello, need some guidance. Tv powers on insignia lights up, backlight comes on. but no picture. These are know for there powerboard failure. Did general voltage check at harness' and should read as labeled, (see pic) Everything at CN101 (upper right) checks good except the 12.5 pins at 7,8,9,&10 were all reading around 7.2v. No abnormal resistance in wire. no burnt anything. Where should i go next?...
