Re: Panasonic TX-32LZD80 - Seems completely dead
I realized I was a numpty and the new power supply board was actually the solution. I opened the TV earlier to try to remove the new power supply board and noticed that I had forgot to plug in one cable into the adjacent inverter board. I plugged it in and everything works now.
that specific cable had just slipped underneath the inverter board when I had removed the board to check it and then put it back, so I didn't realize there was that unplugged cable which still needed to be plugged back in. Thanks for the help!

Re: Panasonic TX-32LZD80 - Seems completely dead
Ok, thank you vinceroger. I see a replacement inverter board on ebay which isn't that expensive, but if the one backlight is off like this, it makes me wonder if its not just the one backlight which is broken, since one turns on and the one doesn't, instead of both being dim.Leave a comment:

Re: Panasonic TX-32LZD80 - Seems completely dead
Ok thank you. I posted photos earlier, as far as I can see it looks like there's only the one inverter board. I guess if something is wrong/broken with the backlight then I may as well give up, since I can't find a replacement part online for this specific model's backlight. Though I've been searching "TX-32LZD80 backlight", so maybe if I open it up and can find a specific part name on the backlight, that could work. Though the backlights I see for similar models are so expensive second hand, it may just be cheaper to buy...Last edited by walkingtv; 12-11-2017, 05:04 AM.Leave a comment:

Re: Panasonic TX-32LZD80 - Seems completely dead
Ok I see, thank you. Thing is I already spent quite a bit on the power supply board, which did at least make a tiny bit of progress, and if I have to replace another expensive thing, it would be cheaper buying a new fully working TV I think :/
This is a video of how it looks. I have a few seconds to try to get something on the screen before it switches itself off. Right at the end of the video you can see where I managed to get a video playing, with audio, but it switches itself off soon after.

Re: Panasonic TX-32LZD80 - Seems completely dead
The image does almost immediately switch off though. So the t-con fuse is still ok even though the image almost immediately disappears?Leave a comment:

Re: Panasonic TX-32LZD80 - Seems completely dead
Another update: I did manage to get a video playing on the media player, I get a dim image and sound, but as usual the TV switches off very soon, like after 4/5 seconds. The image disappeared just before the sound cut out. Also the screen image tends to turn on briefly for 4/5 seconds and then goes off, and then turns on briefly, repeatedly, until the TV switches off by itself.Last edited by walkingtv; 12-10-2017, 01:24 PM.Leave a comment:

Re: Panasonic TX-32LZD80 - Seems completely dead
I don't have a DVD player, but I was trying to play a video through one of the hdmi ports with a usb media player, but it switches off so quickly that I don't get a chance to test it. But I could see menus/setting menus of the TV itself when I pressed buttons, and the channel information, that kind of thing, eventhough its not linked up to any sky/freeview tv box etc so the image was black aside from the menus. Aside from the brightness not being right, it was like half of the screen was a lot dimmer than the other half.Last edited by walkingtv; 12-10-2017, 01:00 PM.Leave a comment:

Re: Panasonic TX-32LZD80 - Seems completely dead
An update: I just replaced the power supply board with a new (second hand) replacement one that I bought. The TV does actually switch on now, and I get an image, like no signal, or if I press the menu buttons I see menus come up etc, but then it switches off by itself after a few moments. So progress has been made but its still not quite there. The brightness is also not quite right, for a split second the brightness is on full/proper strength, but then it dims, and the switch off happens. I'm hoping that replacing the T-con fuse...Last edited by walkingtv; 12-10-2017, 12:34 PM.Leave a comment:

Re: Panasonic TX-32LZD80 - Seems completely dead
Ok I've tried to take more clear photos, its night time here though and difficult getting perfect photos. Otherwise I could try again tomorrow during the day light.
Yes I think that is the sub power supply board picture.
Here are more photos, I'd tried to photograph what was requested.
The whole backside of the TV.

Yes I unplugged the connectors in that photo 3 to look at the other side of the board.
Ok thanks. Do you think the Tcon fuse by itself could have caused it to get so hot and caused all these symptoms of it being totally dead?Last edited by walkingtv; 12-07-2017, 08:42 AM.Leave a comment:

Re: Panasonic TX-32LZD80 - Seems completely dead
Hi, thank you for the reply. I do not have a voltage meter right now unfortunately, I was hoping to fix it without one ideally, if that's possible.
I have looked at the TV more properly now, and I see that I think several parts on the power supply board have burnt out (first two photos). The other boards look fine though (rest of the photos). Do you think that if I bought a new power supply board that it should fix the problem, or do you think there's very likely other issues too? If you had to guess? Thank you...

Panasonic TX-32LZD80 - Seems completely dead
I have just gotten a Panasonic TX-32LZD80 TV for free, the owner said she thinks the light/bulb is blown, but I'm not sure that she actually has any idea what's wrong with it. I immediately put a new fuse in, but there is no sign of life whatsoever after I plugged the TV in and tried to turn it on. When I press the on switch on and off, nothing happens, there is no green or red ON/standby LED, absolutely nothing. I hear nothing happening either. Pressing the on button on the remote does nothing either.
