    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!!

        While you were testing your TV, do you remember if the led on the main board turned on at all?

        I have this exact same TV and by looking at some videos I noticed the main board has a led that should stay solid when everything is working properly. In my case, I have no picture, no sound, all voltages from power board seem ok. But when plugin in TV you see the power led briefly blink and start dimming off. While the back cover removed, there is no led on in the main board.

        Given that all voltages seem to be ok and not fluctuating in any way, everything points out to be the main board.

        I'm having a hard time finding it online from any of the major tv part sellers.

        On ebay I cannot find my exact same model that has the same part numbers you posted.

            Mine had this exact same problem, the main LED never came on, even the back of the main board had the same residue. Once i swapped the main board it came to life. When looking for a board make sure to go by the info that's on the white sticker!

                Hello, i am working on Vizio M70-C3. It can hardly power on, it takes 15 power button presses or remote. Seems like eeprom problem that I seen before but all reading online says that this tv has power board or main board problem.

                Vizio M65-E0 No Picture, No Sound
                by ggil44
                Hi I inherited a Vizio M65-E0 that isn't working. It must have been dropped on the corner because I found that the infrared circuit had a capacitor with one end broken off of the board and some green corrosion around the plug to the main board. I re-soldered the capacitor and cleaned the corrosion well and tried turning the M65-E0 on and I was successful. My problem is that while the back lights come on and appear to perform local dimming there is no picture or sound. It kind of looks like you are looking at the TV through a very dense fog, where changing the input on the remote will change bright...

                Vizio m65-c1 picture flashing on and off on the screen
                by maricm
                HI all,
                hope someone point to the possible issue before I start buying replacement parts.
                Tv starts normal and responds to remote fine, PSU voltages mesured fine 19v was 18.9V under load and 19V with main board disconnected.
                Backlight stays on all the time,
                Sound works fine.
                screen keeps changing form black to full picture in about 1sec intervals.
                Picture looks fine with no visible artifacts.
                I have disconnected backlights and flashlight test confirmed that picture is still doing the same.


                Disconnecting left and right ribbons on...

                VIZIO E70-E3 Half picture with half TCON
                by Fly_Among_Stars
                Hi,
                I have a VIZIO E70-E3.
                Symptoms: Black screen, no picture, but LED backlights are working.
                I probed the power board and voltages are as listed on the board.
                Main board appears fine, too.
                I believe the problem is either a bad T-CON board, or connection to LCD, or bad LCD.
                There are two separate ribbon cables feeding the LCD.
                If both are connected, the screen is black.

                If only the ribbon cable that feeds the right side of the screen (when viewed from the front) is disconnected, the left side of the screen shows picture and...

                T-con suspect issue. Both ribbon cables no picture. One ribbon cable ok. (58pus8545)
                by Tr0ll
                Hi guys! I realized you have a lot of knowledge here so i am hoping you could point me in right direction with my odd issue.

                The Tv is a Philips 58PUS8545/12, it had no picture but working backlights.

                Original T-con:
                Opened the Tv and tested to unplug one ribbon cable at a time. With this test i could see that i got fine picture on both halves as long as there was only one ribbon cable connected, with two connected picture were gone.

                First replacement T-con:

                I thought it might be t-con and ordered new t-con from china(supposedly tested)...
