    Re: Vizio M492i-B2 Won't Turn On

    I know! Can't get a break from this TV! What would I need and how much would it cost to fix this? or would it be so expensive that it would be cheaper to buy a new TV?

        LCD panel is the most expensive part of the TV, not worth it.

            Thank you guys for all your help. I really appreciate it! It really sucks to have gotten this far only to find out that the display is cracked. Already checked and doesn't seem like there even is a replacement display out there. I will inform the owner that he would be better off just buying a new TV. Thanks again for everyone's help!

                That's too bad... all the work for nothing. However, I'd still like to know where the PSon / BLon signals are with the new board for future reference.

                    I will see if I can find it now and let you know where it's at.

                        Seems that the blue, white, and orange wires on CN901 go up to 3.3V when I turn on the TV. Hope that helps!

                            Just saved this same TV from a trash compactor. I have a great chance that it's just a board inside and doesn't have a damaged screen because it came from a Charter Spectrum division office. I am going to order the TV repair kit from shopjimmy.com and replace everything. Will update once I get around to the repair.

                                VIZIO M65-C1 Does Not Turn On
                                by Mulp
                                Hi All,

                                I am having an issue with my Vizio M65-C1 where it does not turn on. When I plug it in the stand by light on bottom left of screen turns on (white) then fades away. If I press the power button it turn back on and then fades until it is super dim.

                                When I remove cover, there are no illuminated leds on the main board, I've seen others with a red/blue led that turns on.

                                I've done some research and what is interesting is my voltages all seem slightly different from other people. For example +5/3.5v is 3.48V when on which is different from others on here....

                                Hello, i have some issues with my laptop Lenovo Y700-17ISK (motherboard BY511 NM-A541), it started when i turn on the laptop, but the lcd wont turn on, i then connected it via hdmi to tv and screen was ok. So i thought maybe lcd stripe is faulty, i removed the bottom cover, disconnected main battery, reset the cmos by disconnecting battery for 1 min, then slighty move the lcd stripe. Conncted power supply and tuned on my laptop, the lcd turn on, it started to load os, then it turn off, after a second it turn on, then after like 3 seconds turn off again, and so on. Removed power supply, waited...

                                MSI GF63 THIN 11UCX (MS-16R6) LAPTOP WON'T TURN ON AFTER RESTARTING
                                by RdeveLabs
                                To all the members here...

                                Let me tell you a little bit about what happened to my laptop (MSI GF63 THIN 11UCX model: MS-16R6) that “maybe” you know how to solve this problem.

                                So before this problem happened, my laptop was running smoothly. When I wanted to restart my laptop, it looked fine at first. But after I waited for this restart process to take a long time, until finally I panicked (because the restart process did not finish plus the laptop screen only showed a black screen), I immediately pressed and held the power button to force the laptop to turn off. But...

                                Acer Aspire 4520 won't turn on after reboot
                                by robante15
                                Hello, I have an Acer Aspire 4520 from a couple of decades ago and I want to repair it solely for nostalgia.

                                It happens that when I turn it on after having been disconnected for a long time, it turns on without problems, it tells me that the BIOS has been reset and that it will load the factory settings, if I tell it to continue, the computer turns on and everything works fine.

                                The moment I turn it off and want to turn it back on a second time, or restart it and try to start it again, it no longer gives an image, and it no longer responds.

                                If I remove the...

                                Dell latitude e7470 not turn on .power buton on off and Run Power problem
                                by masoksian
                                Hi everyone,

                                I am dealing with the problem of turning on and off my Dell e7470 notebook.

                                The battery charge light is solid white, I press the button, the power indicator and the light on the button are solid for 1-2 seconds and immediately turn off.

                                The system does not turn on, there is no post.

                                I removed the RAMs and changed them, changed the battery, RTC battery, AC adapter, removed them and waited, tried again, it does not turn on.
                                The problem continues in the same way.
                                I tried to turn on the Fn key, nothing came to the screen....
