Re: Vizio VO370M-C Vertical Lines
Ok, I'm finally seeing the test points.
What dcvolts should they be? all the same?

Re: Vizio VO370M-C Vertical Lines
Well, I know you didn't ask for VDD, but I wanted to measure it for sugar & giggles. Few seconds after testing VDD the TV turned off by it self... I was testing it screen down on the floor... It turned off about 3 more times, ON for only 35sec at a time. Then I stood the TV upright and now its working fine...
I tested the VDD again, but the TV is not shutting down anymore.
VDD=16.17
VCOM=7.48
VGH=initially 12.67 went up to 13.30 and stayed there (are these values depended on whats playing on the screen?)
VGL=7.46
VCC=3.297
VCC1.8=1.800
Thank you budm

If the T-Con board is bad, does the number on the sticker on back of T-Con board must match the replacement?Attached Filesif you find these attachements useful please consider making a small donation to the site

Re: Vizio VO370M-C Vertical Lines
I know it very well may not be the T-Con board, but if I want to buy one.
On shopjimmy.com the one has the same part number as mine but has less components on the board, will that board still work in my TV?
My partial p/n on back is 1579A, so the part I am looking for is 6871L-1579A?
Thank you,

Hello, I have a screen in where sometimes when I open it pop-up vertical multicolor lines (I would say the most of them are green). If I tun off and turn on the screen the lines dissapear or if I leave open the screen after approximately five minutes the lines gone. I measured the below voltages on the main PCB and on the T-CON board and the voltages are the same when it doesn’t display the vertical lines and when it displays the vertical lines. Also, I cleaned all the connectors very good with IPA. I moved back and forth the connectors and the COF tabs but the vertical lines didn't displayed... -
I picked up a Vizio E70-E3 for free that shows Vizio logo and then goes to a black screen. Original owner said he started having wifi issues and then he tried to reset the TV and that's when it wouldn't boot up any longer after his reset attempt. I picked up a replacement main board from eBay that matches the same model # board as the original from the TV.
Original main board - Shows Vizio logo when TV powers on, then goes to black screen. Doesn't boot up. No screen issues with any lines on start up Vizio logo.
Replacement main board - Boots up fine, but starting... -
Hi guys…I need your help. My cousin ask me to fix her tv. The tv when I went to pick up showed 3 horizontal black line. So I know it was a bad panel issue but I could try to fix with the tape method so I said her I could fix easy. When I come back to home, I turned on the tv and now the tv show vertical line colored….and the problem is that I unplug the ldvs cable, first the right side then the left side I still have the lines. The lines never disappear. When the right side is plug in I don’t have nothing on the screen only this vertical lines, when the right side is unplugged I have picture... -
Failure Symptom
No picture, just red vertical stripes. Google search shows quite common problem for these recent Vizio M series although red vertical stripe pattern may differ. Some call it "Netflix" boot screen haha.
Where is the short?
Panel has 4x buffer boards. Quickly found the 1/4 panel buffer board with the problem by selectively disconnecting buffer board flex cables.
Having recently fixed another Vizio with similar symptoms that was a shorted ESD diode array ( link ) Probed the ESD diode array but... -
Hello everyone,
I've recently been given a Sony 8k Z8H. It's got a white screen with two vertical black bars. At times it's given me the 5 blink Tcon code. Testing voltage on the Tcon I can see some low or missing voltage. I've done a basic visual check of cables and the COF. Not seeing anything obvious. The original Tcon seemed to have good caps until turning it over. On the bottom I found maybe 10 caps with both sides of the caps shorting to ground. I thought ok these caps and likely other components on the Tcon are shorted so let's try a replacement Tcon. I just received the...
