Hello everyone!

Yesterday i bought a Pioneer PDP v402E with 26k hours on the counter. There is no burn-in, the colours are nice and I realy like this beiutiful monitor, but it has got a issue. When I turn on the OSD, the letters are shimmering on the edges:

I think this could be a problem with the power suply, because it is making a buzzing sound. Any ideas?


I can't watch your video on my phone, but that buzzing you're hearing is probably good old fashioned plasma buzzing. I also thought something was wrong when I first got an old plasma.
The buzzing changes pitch/volume based on what's on-screen right?

Hopefully this is the appropriate thread for this, if not feel free to zap it. I didn't think starting a whole new thread was appropriate.

I have a Panasonic CT-27D11E that I'm using for my consoles. I'm using a Shinybow SCART to Component adapter with it and it seems to work really nice. My only problem is that the picture is tilted a bit and I can't figure out how to fix it. If you look at these pictures you'll see that the left side has a bit of a tilt, but it's not just a normal tilt as the right side shows a different kind of tilt. I entered the Serviceman menu but I didn't see anything to do with geometry controls other than V-Size and centering. I'm no stranger to cracking open the back of the TV (I have it open now actually) but just twisting the yoke a bit isn't going to fix this I think. What kind of adjustment do I need to get this back to a reasonable state? IS there anything I can do?

There's also a problem with some bowing inward in the center on the bottom (see the last picture) that I can't figure out how to fix either. Any ideas/

I find this is pretty normal (I would say more often than not and I have a pretty huge number of PVM's which have gone through me) in 20"+ PVM's.

In BVM's, no. 14" PVM's, usually no. Maybe not to quite this degree of your pics (unless it's clearly evident the monitor has seen a LOT of use), but it's pretty common to have it there on the sides to some degree (the white slightly shifting over into the red). No fool proof way to fix it (want to say I've played with the rings before, and some older larger sets have a pot which will adjust only one area of the screen at a time), but I'll stay tuned if anybody has suggestions which I can try next time (have ~6x 20" right now I can mess with in fact).

You are probably right, the buzzing changes pitch depending on what's on the screen. I found a TV repair guy who is familiar with those PDP monitors, and I will bring it over to him after the weekend. But he told me not to give myself too much hope because it could be the screen...

Those PDP v402 monitors are realy old and rare. I own CRT's that are newer ;) I bought mine for cheap, so it wont be a big deal if it's impossible to fix it, but it would be great to have one that's fully functional.
