I understand what you are wondering.

I am curious about the hours and programmed volt increases though.
Please post what the new board does for you.

I am still getting fluctuating brightness levels. The picture on the other hand looks pretty sharp, but I think I am getting more crush now. Could just be me though.

Good thing. :thumbs:

From my understanding people with the VT30's have got their A boards replaced and the problem with fluctuating brightness went away after the swap. I, however, still am dealing with the issue after a board swap on my VT25.

Seems the A board resets the voltage to
new condition. So that is why I said what I did.
Sad thing, it does not last.

HDMI IN and OPTICAL OUT SIMUTANEOUSLY?


Hello,

I have looked through this Official Thread and have had a hard time finding what my problem is.

1. I am connecting my HTPC to my Yamaha RX-V671 receiver via HDMI, then from the receiver to the TV.

- the audio works great on my Yamaha and is full 5.1

- However, i was hoping to back feed the audio from the P50vt20 into my receiver to drive the 2nd zone.

to do this, i bought an optical to analogue convertor.

2. but i have found that in this configuration, the audio is not being fed out of the optical port.

3. when i connect the HTPC directly to the TV via HDMI, I am able to get Optical audio out - to my convertor and then to my receiver (of course on 2 channel, which is all i want)

my question is:

- does anyone know if it is possible to have the 5.1 through the reciever and then get audio out of the tv?

- or is it that my reciever is only sending video and not audio?
- but then again i do get audio out of the TV speakers.

- would 1.4hdmi cables make this work?

it seems that is probably configurations in both the yamaha and the tv that i have messed up.

it is very frustrating, but i want this setup so i can feed music from computer to the main speakers and to my outdoor speakers (via zone 2 on the yamaha) at the same time.

thanks for your help in advance!

until today. What in the world is this?

I have switched HDMI cables, swapped inputs in my AVR, and switched inputs on the TV as well. Its not burned in, but a weird block of colored lines that slightly pulsate. Almost invisible with bright pictures on screen, but highly noticeable with dark scenes.

Have any of you seen this before? Any ideas?

Good luck, Mike

Hi All, just came across this amazing forum and it's certainly a great learning experience. I just got myself a VT20 after reading through the site. However, I have a small suspicion about my unit.

When I turned it on, I noticed at the bottom portion of the screen, where the vierra cast menu normally is, there seems to be some sort of image retention, or burn in of sorts. The panel is not showing any content (in fact just waiting for something to come in on HDMI 2), but there's clearly something visible there.

Being a little suspicious, I checked how to enter the service menu, and try to get a read out of how many power on hours the panel has had. The values read:

Time:04411:00 Count:0000573

Having just gotten the panel, I'm not sure if these values basically mean the panel has had about 4000+ hours of use and it's been turned on/off about 573 times.

I'm planning to give the vendor a call on this, but thought I checked with the experts here if my interpretation is correct.

Also curious, if I may, would be the amount of hours your panels had when you received it? From the other threads or post, most seem to come with about less than 100 hours on the panel.

Hope to hear from you guys soon on this as I suspect I've been taken for a ride. It's supposed to be a new panel, but, didn't seem to be the case. Hope to hear your thoughts on this bits before I engage them and panasonic. Thanks in advance everyone!

I'm just a bit concerned if the vendor decides to replace a new unit for me, he could very well replace it with yet another display unit, BUT with the power on hours reset to zero. Not sure if this is possible to be done by a layman or requires a panasonic engineer to do it?

Hopefully the procedure is not so straight forward.
