    Panasonic TCP50VT25 Audio

    Set has been working flawlessly since repair of su/sd/sc boards. When trying to play an MP4 movie, got the message "on screen audio not compatible". I have no audio period since that message displayed.
    Video is clear as a bell channels change quickly..just no audio.
    Unplugged from AC power for 15 min...still no audio.
    Any ideas??

    TIA

      Unplugged the mp4 source? Remove all equipment like amplifier/soundbar etc so you just have the tv only.

      Tried to restore to factory settings?
      I only repair Panasonic plasma tv's! Currently owning a TX-P55VT50 and still searching for a ZT60!

              According to the tech serv manual..even if speakers go bad or wire pinched..should go off on a protection fault. The fact that I have video means all hardware checks out. going to power down for an hour then try factory reset.

                  This is weird..In Advanced Audio settings, input for HDMI1 was changed to Component instead of Digital..changed back to Digital and sound returns. CPU must have changed it...tried it again on same file...changed again. Wow!

                      was interesting. I was thinking along the line of it changing something although never come across this before. Glad it's sorted , sure to help someone down the track

                          Well, according to all I found in tech serv manual, if it has video, it's not hardware..bad speaker, pinched wire, or bad IC will trigger protection fault with blink code.

                              by samson7point1@yahoo.com
                              The Problem: This player has a toggle switch to select between Stereo, Mono R, and Mono L. Regardless of the setting it outputs the sound to both the L&R audio jacks. In the Mono R position, the audio output level is normal (from both the L and R audio output jacks), in the Stereo position the audio output is about half the volume, and in Mono L, it's about 3/4 the volume. Something about putting it into Stereo mode is causing the volume to drop significantly and I can't figure it out.

                              The player processes the audio signal using two different reference frequencies. The "R"...

                              I picked up a Panasonic NH-P70G2, though it would apply to the NH-P80G2, NH-P70G1 and NH-P80G1 models as well, as maybe some other models. This one was coming up with a H86 error. After lots of testing and googling it was an error with one of the thermistors in the condenser area.
                              The attached French service manuals is incorrect, TH11 is gray and is a 95k thermistor and TH12 is black and is a 35k thermistor.
                              In my case TH12 was bad. I was able to get a 35k thermistor on AliExpress. It's 6mm in diameter.
                              Unfortunately the whole machine has to come apart to fix it.

                              Hey everyone!

                              I've gotten this TV for free, neither have it seen a TV repair man, neither have it been opened before.

                              This post describes my entire troubleshooting process of this TV.

                              When I turn it on using the ON/OFF switch at the side of the TV, the light rapidly flashes green, then it stays on, but it does not react to any of the remote buttons, side buttons, and doesn't play audio.

                              I've taken the unit apart, and I've started to check some voltages:

                              • On the P11 connector, there is 15V DC only for a brief moment, then it goes

                              Roland KR-3500/4500 Digital Piano. Crackling audio sound on all keys -Fixed
                              by i_am_patch
                              Hi All. I had a Roland KR-3500 Digital Piano (similar to the KR-4500) that exhibited a Crackling audio sound on all keys. After reading somewhere about someone with a similar issue who had replaced all the Electrolytic caps I decided to also go down that route. (Spoiler : It worked !) After some basic troubleshooting I determined that it could be noise feeding thru from the Keyboard scanning since the Demo tunes played back undistorted and the Audio amp / speakers were fine ( Inserted an Audio signal into the rear Audio input). After extracting the main board from the shield, I replaced 7 Capacitors...

                              Panasonic TC-P55ST50 8 blinks then no blinks
                              by Andre Gilbert
                              Hello! yes I know there is already lots of information about this issue. I have a Panasonic TC-P55ST50 that originally displayed an 8-blink error code. Following the troubleshooting flowchart, I ended up replacing the SS board. However, even after replacing it, the issue persists. The TV turns on and stays on without displaying an image, and continuity is confirmed on all connectors. What am I missing here🤔?
                              Ok Im a mechanical engineer ...but I thought I was able to follow a rather simple flowchart for electric troubleshooting 😂.
