Re: Vizio M65-C1 - no picture, help!
I just want to say a big THANK YOU to you guys for your help! With that help I was able to make a informed decision to replace my main board. It was a little hard to find, but a refurbished one eventually came up on eBay. It costed $150 with shipping, but that is so much less than a new TV. I put it in last night and all is well!
I'm totally coming back to this forum next time something is on the fritz. Thank you!!

Re: Vizio M65-C1 - no picture, help!
So, I am looking for this main board and it may not be easy to find. I don't feel like my TV is that old, but maybe it is -- at least for sourcing parts.... any suggestions on where to find parts? I have looked at ShopJimmy, eBay, others that turned up in the Google search.... everyone is out of stock
Anybody here have one of these?
I am also open to repair shop suggestions where I could bring or send the board in for repair...
The board number is: 715G7288-M02-000-005T
The white sticker says: GXFCB0TK0009020X...Leave a comment:

I heated up the main board with a hair dryer and powered it on. No change at all.
I also cleaned up the residue I had mentioned with some isopropyl alcohol. No change at all (except it is cleaner)...
Any suggestions on what to try next?Leave a comment:

Re: Vizio M65-C1 - no picture, help!
After doing some research on "re-flowing" I have some questions before I attempt this...
first, it seems like a heat gun is recommended instead of a hair dryer, right?
also, I need to remove the heat-sink and aim the heat right at the chip, right?
besides that, I am wondering if that residue in the picture on my last post is just excess flux, or something to be worried about that could be contributing to my problem? Thanks!Leave a comment:

Thanks...
Should I heat it from the top or bottom? I just took out the screws that hold it on and the back is covered with some sort of residue. Does it look normal?...Leave a comment:

Where specifically should I point the hair dryer? I'm not familiar with the names of the boards......Leave a comment:

Re: Vizio M65-C1 - no picture, help!
Thanks budm,
I rechecked the PS-ON and I did make a mistake. It is reading 3.68 with the power on
Pin 15 is reading .149 with the power on, so it is close to what I got the first time (not quite sure why there would be a slight difference...).
The 3 black caps read 19.09 DC volts -- is that what you are asking or did I set my meter to the wrong setting?Leave a comment:

Re: Vizio M65-C1 - no picture, help!
I took those screws out to take the board out and look at the bottom and was lazy and only put two back in so it would be grounded when I tested further....
Does the PS_ON reading give any clues of what to look for next?Leave a comment:

Vizio M65-C1 - no picture, help!
Hi,
This is my first post here...
Last night my TV broke. I was streaming a show and the TV froze. When I attempted to turn it off/and back on all I get is a black screen. The power led indicator goes on for about 20 seconds, then it blinks 15 times and the TV restarts... it does that again and then it powers down. I don't see anything at all on the screen, no logo or anything at all.
I tried the suggestions from the Vizio website including unplugging, holding the power button for 30 seconds and plugging back in. No differance.
I unplugged overnight... -
