    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.

              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....

                  by pajdek
                  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...
