    Rca led 65g55r128q

    I Have A Rca 65" led hd TV Model # LED65G55R128Q
    Turned Tv Off ...Now When I Turn Back On Screen Flashes On Then Off
    You Can Hear Sound & See Picture When It Flashes On
    Have Tried The Factory Reset Of Unplugging set & Then Hold Power for 1 min.
    The Plug Set Back In While Still Holding Power Button
    Now Set has Input Screen Flashing Then Black Screen I Have Tried To
    Change Input Back To HDMI 1 With Remote To See If I Still Have Sound & Picture For Brief Flash But Can Not Change Input With Remote Now
    I Have Not Taken Apart Yet Was Wondering If Any One Had Run Across
    This With RCA Before.

      probably a bad LED in the backlight strings. Measure the DC voltages between each LED string, while the LED's are on.

          Would he hook the volt meter negative lead to chassis ground in order to measure DC Voltages on each LED String? what would be the typical voltages on the strings? would a different voltage on a particular string indicate that one of the LEDs is bad? this is my brothers TV and he hasn't had a chance to remove the back yet for troubleshooting, I'm trying to gather as much information as possible to help him figure out the problem. any help anyone can give is appreciated. Thanks.

              We need good CLEAR WELL FOCUSED showing the pictures of the whole board and the whole backside of the TV showing all the boards so we can see what we are dealing with.

                  I think the model number is LED65G55R120Q he said there is a bracket in the way covering up the 0 so it looks like it was an 8

                      Samsung UN55J6200AFXZA Splash Screen Comes up, goes out, screen flashes one time and then tv won't turn off.
                      No picture. No sound that I can tell. Backlights are on and have been checked. Flashlight test no image on screen. I replaced the Eprom chip hoping that was the problem but nothing changed.
                      Please help. Thanks in advance!

                      LG55UB850V no picture or audio - flashing LED's help please?
                      by Scoff
                      Hi, I'm looking for some help with attempting to troubleshoot and hopefully repair my trusty LG55" TV.

                      I'm reasonably comfortable working with electronics, but far from expert level! I have more experience with auto-electrics than anything.

                      We recently had a power cut while the TV was on, and since then, when the TV is switched on at the wall, the red standby light comes on like normal. Then. when you press the power button on the remote or the TV to switch it on from standby, the standby light flashes 3 times and then goes out. There is no audio or video at...

                      Sony OLED XR-77A80J - Initially dead, now 4 Flashes
                      by thstuff
                      A) TV initially dead
                      B) On a hunch of a locked up Google OS, plugged in a USB memory stick with latest FW and plugged it in. It booted into the update screen, completed the update and restarted to Home screen.
                      C) Was able to perform a Reset from Settings menu and completed out of box configuration.
                      D) Ran a 4K screen saver demo for about 6 hours, then turned it off for the day. Did not notice any stripes, dead zones or other artifacts in the image.
                      E) Powered back on and it now runs for a few minutes before relay clicks, screen goes blank, Main Board Red Digital Optical...

                      Zenith Z50PJ240 - White Screen with 'Power Only' displayed
                      by cmonkey
                      Turned on my lovely plasma and after about 30 seconds the screen below showed up. None of the inputs are responsive, just the red light flashes when I push it. Remote doesn't work either. To turn it off I need to unplug it and when I plug it in again it turns back on to this screen.

                      I only found one reference to this issue with a different model but it didn't look super reliable. Only mentioned a 'main board fault'. The main board for this one is on ebay for $34 so might need to go with that.

                      Anyone seen this before?

                      Thinking about it some more, it happened...

                      ipad pro 9.7" blew a SMD component while replacing the screen 🤦‍♂️
                      by ipatch
                      i have an ipad pro 9.7" (1st gen) A1674 where i replaced the screen, but never attached the screen to the frame/chassis (glued down) due to the ipad being previously dropped so the new screen would never fit in the frame properly. so i need flex/bend the chassis to eventually fix the new screen in properly. so i temporarily just applied blue tape around the edges of the screen to keep it in place. when watching videos with the ipad the screen started flicker, so i though maybe the new quasi cheap amz screen i purchased was going out. so i disconnected then reconnected with power still on,...
