Did You Know!!!!!!!

[Steffche]

Last night the kids put on one of their DVD's..."School House Rock", which when I looked at the tv had a VERY BLUE tinge throughout the entire picture. My heart started racing....I thought something had happened to the tv...or the kids had touched something they shouldn't have. I turned the set off...and then back on again, but no difference. Everything seemed ok in the picture settings......what the hell was causing this blue tinge???

Well....soon I discovered the problem. The night before, I had been playing around with my PC, which I had connected to the front of my Panasonic Viera (TH42PV30). I had decided to try and use my laptop PC as the dvd player to see if it was any better than my Pioneer DV-344. Usinig DVE I played around with the PC menu on the TV....which is of course a very different menu system to what is used for AV inputs. It has the little menu box that appears in the top right hand corner of the screen, which has options similar to my AV picture settings menu, but has alot more options such as Gamma control, Red and Blue cuts and gains adjustments, size and position (All of which I believe should be available in the standard AV picture menu).

Anyway to get to the point, I had ended up cranking the B-Cut settings to +9 in the PC menu in order to get a very nice looking greyscale using the laptop as the dvd player.

Here's where it gets interesting...........DID YOU KNOW that the PC settings for White/Balance have an effect on your regular AV inputs as well!!!!!!!

I couldn't believe it......spent $300 to get my v calibrated...going in and out of service menu blah blah blah....only to find that you could easily screw the whole thing up by changing the blue and red adjustments in the PC menu........

So in the end, I normalised all the PC menu settings and then went back to AV2 (DVD player) to continue watching Scool of Rock....and as one would guess....all the blue tinge is gone.

WHAT A JOKE!!!!!!

always write down settings before messing, can get you out of a whole heap of trouble (unless you turn IR off)

 

[Steffche]

What's IR, and what do you mean by turning it off?

BTW, I don't mean PC menu as in service menu, I mean when you are in PC mode (ie, pressing the PC button on the remote control when you've got your PC connected to the VGA port on the front panel). This menu is different to the normal picture menu when you're in AV mode, it has alot more options, but some of these options such as whitebalance effect your AV modes too!

always a good idea to note settings...............
On the PW range of panels, you can turn the Infa red remote control off and you cant turn it back on with remote................need a dealer with a laptop an RS232 protocols.....$$$

 

[Steffche]

I am aware of that, but I still don't see how your response has anything to do with my initial post.

 

[hornydragon]

it ios a basic warning to all to be careful and to note settings before playing with settings. You have been unfortunate and the memory system does seem a bit odd....does it mention any of this in the manual???

I think you're confused as to what I was trying to say.

I connected my laptop to the front VGA port on the plasma. To switch to my pc I have to press the PC button on the remote control (or I can press AV3 until my pc screen is visible on the plasma). When I then press the menu button on the remote to bring up the picture menu, it has a different layout to when I am watching a DVD (connected to AV2-component video) and I press the menu button.

So one would think that any changes made to picture settings while in PC mode would only affect the PC mode, but thos os not the case. When I switch back to AV2 to watch a DVD the greyscale is affected by what ever changes I made in the PC menu....

It's hard to explain..or maybe I'm just not good at explaining it?

In the end....I have not entered Service menu at all...these menus are all user menus, accessed by pressing the menu button on the remote.

oh yeah i under stand that, i think the reason why is because the Veira (in UK) has a PD series chassis feeding the panel and direct VGA connection so VGA settings also cover panel overall settings ther emay be a way to "balance" them......
Odd..............
