    Panasonic TH-50PZ80U Plasma No picture no sound no blinking error

    Hello. I have a Panasonic TH-50PZ80U Plasma TV. 4 weeks ago I had no video for about 30 minutes, but then, everything started to work fine again, but not because of anything I did.

    Today I am watching a show on the unit and I loose the image. The unit was still powered on and primed. Remote control access all works including power, vol, menus, etc... Red Power LED steady on and no blinking. unit DOES NOT power off by itself after 15 minutes.

    I was using HDMI input but tried component and composite, with same result, no picture.

    Any ideas for next steps of diagnostics please?

    Thanks.

      Pull the back cover off and look for any bulging or leaking capacitors, or any other obvious problems. Be sure to leave the tv unplugged for several hours before working on it.

              Most likely an A board fault. Try disconnecting P5,P6,P7 on power board and LVDS on main board, when TV is powered on so you get a full white screen?
              Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

                  Panasonic Oled 55EZ950E, no picture, red led blinking every 4 sec
                  by riparo
                  Hi everyone, I have a Panasonic OLED TV model 55EZ950E, as soon as I turn it on I don't have any image the LED goes from green to red LED blinking every 4 sec, I found the service manual suggests checking OLED PANEL, PB BOARD, T-CON connectors but it seems like everything ok, I didn't find any burns under the pb board
                  I attach a link to download the service manual, thank you for anyone who can help me

                  by Tof
                  Hello everyone, here is the issue I am facing with my Panasonic Oled TX-65FZ800e.

                  When the TV has not be used for some hours, I power up the TV with a video input and the image is displayed perfectly for 30seconds and then the TV switch off with the red light blinking every 4 seconds for ever.
                  The service manual explanation: EVDD_SOS (EVDD 24V error) with check point (oled panel, P board, A board, T-CON)

                  I opened it and found a burned connector on PB-board on the 24V pins.
                  The 24V wires have change a bit of color due to the overheat and the corresponding...

                  Panasonic plasma TX-P42ST50 - 6 blinks
                  by jm1234
                  Hi,
                  anyone able to provide the service manual for old plasma Panasonic TX-P42ST50E?
                  It turns off almost immediately (0~5 seconds after pressing the on/off button) and starts flashing the red diode 6 times.
                  I disconnected the left-hand side board (SC?, both the ribbon cable and the power cable to it) and also another ribbon going to bottom left board. Then the led signal is 8 flashes. According to service guide to another Panasonic plasma it would mean the left-hand side board is faulty. But I'm not sure it 100% applies to my model.
                  I checked that board for any obvious faults...

                  Hitachi 55HDS69 55" Plasma TV - No Picture But Sound
                  by KYBOSH
                  Picked up a bahemoth plasma TV not too long ago and just now getting around to looking at it.
                  No picture but you hear the TV static (white noise) playing loud and clear.
                  The back was already taken off (and no screws were provided) as the previous owner had already taken a look.
                  But it seems they didn't get too far and just left it.

                  When I first took a look I was amazed at how pristine the inside looked.
                  Its as if the TV had been in a time capsule.
                  Caps looked like they were just pulled off the self.
                  Copper coils had no sign of corrosion on...

                  Hi everyone!
                  I happened several times, in the search for help from the web, to consult this very interesting forum.
                  So I decided to sign up and I intend to participate actively by making available my knowledge and experience on the subject, I'm a new user but at the same time I'm old in the sense that I have 4 decades of experience in repairing and designing electronics but above all I'm a great passionate about the subject.

                  Having said that I come to the gist of my post on the forum as the title suggests.
                  For my passion for technology I'm now collecting several...
