    Vizio VO47LF Random flickering

    Hey everyone. I been watching these forums for quite awhile now. Anyways, I have a Vizio LCDTV VO47LF with flickering problems. Theres quite a few videos on youtube with other people with the same issue.

    I was wondering if anyone have any idea what might be the problem? I have checked all the capacitors and they seem good. The caps on the PSU are chemicon. I have also measured the outputting voltage from the power supply and they seem to be in check.

    I also checked for cold solder joints and there wasn't any, but I still reflowed most of the pads anyways.

    Thanks

      The second video looks like a signal distortion issue or it's losing the signal - I can see something appearing in the top right - is it the OSD/channel numbers, possibly saying no signal?

          Yeah, I think its just the channel number that shows up on the top right. It doesn't say its loosing signal though.

              I just noticed something, every time its flickers I would press the "menu" button on the remote and the image will pop back to normal.

                  Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?
                  by Tynan Dill
                  I was given this TV from my great uncle. He said it just wouldn't turn on one day out of nowhere, replaced the TV, and gave it to me to possibly fix and use for myself.

                  Upon bringing it home and plugging it up, it showed a standby light.

                  I powered it on and without a flashlight, the display showed the "V" but the lighting is very dim, but visible.

                  The screen seems to blackout and stay black, but with a flashlight I can see the display.

                  With my Playstation 4 connected via HDMI, and running a game I can hear sound.

                  Assuming...

                  ACER BM320 Monitor - Horizonal Flickering Lines After a While
                  by reessi
                  Hello,

                  The monitor started off showing flickering thin (1 pixel) lines horizontally every say 3mm..

                  They are black on the right and gradually fade to nothing on the far left.
                  They start either after 5 mins or up to 2 hours after so annoying for testing.
                  They flicker continuously very fast! With a slight pause milli-second every second.

                  Initially I cleaned the LVDS cable and connected to the T-Con and then it worked fine for 3 weeks but not sure if this was just co-incidence.

                  I tested each half by removing the first the left flex from...

                  Vizio M65-C1
                  by mrtek
                  Hi.

                  picked up another TV. This time is a Vizio M65-C1. TV does not turn on. I had repaired another 60 inch vizio , Bad main board.
                  When power button is pressed, the Power led indicator on the bottom right, turns for a few seconds and then it fades away. No backlight or Vizio logo on screen. Removed back cover and repeated test.
                  This is the TV This TV is a little different from the Samsung I have worked on. Power supply is on the Left side, Main Bd is on the right side, T-CON , not in the picture is on the bottom. I am assuming that the boards in the middle are the LED...

                  10 year old Vizio VO370M has intermittent flickering backlight
                  by xeos
                  I have this Vizio VO370M TV that I'd like to save because it has very low input lag (as good as the most expensive TVs sold today!, https://alantechreview.blogspot.com/...input-lag.html), but it has a very annoying issue: sometimes the backlight flickers (or is just kind of dim). The flicker is slower than 60hz, so we aren't just talking some kind of motion compensation).

                  I was hoping maybe it was a power board issue (aka failing caps) but I opened it up and I don't see any that look bad. I have a budget capacitance/ESR meter if it's worth checking those...
