Re: Vizio M656-G4

That was the ticket. Bezel snaps into place and just needed a little prying to release all the way around. Thanks for the input again.

Re: Vizio M656-G4

Worried about applying too much pressure and cracking the screen. Thanks for the reply.

I was given a Vizio 65" TV with a dark area in the lower left of the screen. I verified the voltages on the LED driver board and determined the LED strips have failed in that area. Trouble is, I have never worked on a TV like this. The bottom section on the back is removable to allow access to the power supply, mainboard, T-con, etc. There are no screws for the bezel and I can't find any information on the web showing how to remove it. Does anybody have some idea how to get into this TV? Thanks, Skipper

Re: (SOLVED) - Emerson lf501em5f - Turns on, shows logo, then shuts off.

Wish I had seen this post before I spent $60 on a main board. Exact same problem with mine. Luckily I had a TV in my boneyard with a cracked screen (main board was bad too). Anybody in need of a main board?

Re: Vizio M50-C1 Nothing on screen, no backlights

Guys, thanks for the participation. Decided to just get the replacement board and TV is now functional. Would like to know more about deep diving on these boards to identify the faulty part. That probably takes more electronics education than I have been exposed to. Will continue to improve and try new things. On to the next one.....Thanks.

Re: Vizio M50-C1 Nothing on screen, no backlights

I have read that post at least five times before creating an account and posting my query. I'm fairly confident it's the main board but was looking for any other possible test methods I could try to confirm. Thanks.

Image attached....

I have acquired a non-functional Vizio M50-C1. Previous posts have revealed higher than expected voltages on the 12v pins (recorded at 19v). Mine is the same. LED on main board illuminates when plugged in as solid red. When powering up, it changes to red and blue. The power indicator comes on then fades out as normal. Nothing displayed on the screen even with the flashlight test. No backlights at any time. Remote functions, turning the TV on and off. Power will cycle about every two minutes. From my reading of others before me, it appears to be a short in the main board. Replacing the board will...

Re: New Members - please post your introductions here

Greetings all. Been acquiring lots of information from badcaps for some time now. Very useful information from you all.

A little background: 23 year retired Marine, Data Systems guy with training in explosives. If I can't fix it, I can blow it up. No training in electronics but I can us a multi-meter to check voltages, capacitors and continuity.

I'm a fiddler (and I don't mean banjos). Love to take it apart, figure it out, fix it and put it back together. Even more fun when it works. I hate seeing two...
