Default Need help with my Toshiba 34HF84

The Toshiba 34HF84 that I ordered just arrived and I am having trouble adjusting the picture. I used AVIA to set my levels and discovered that the light output is MUCH lower than my 26HF84. The color accuracy is certainly an improvement but the 26" ORION just provides a more overall pleasing image. The 34" just looks dim in comparison.

I played with the settings and noticed that I have to set the contrast to the max of 100 in order to match the light output of the 26". And if I turn the brightness past 35, the blacks completely wash out. I tried to let my eyes adjust and tell myself that it was a more "natural" image, but in the end the 34HF84 just doesnt have that 3D 'pop' like my crappy Orion. The colors just arent as bright and details arent as apparent.

The unit was a display model so I am worried that the picture tube was damaged from running in torch mode in the store. Obviously I could go into the service menu and increase the maximum contrast but that probably wouldnt be good for the set(?). Im sure that having brightness at 30 and contrast at 100 is not what is normally required for this set. My settings on the 26" are more like contrast 37 and brightness 32.

Does anyone have any suggestions or could post their picture settings (if you own the same set). Returning the set is unfortunately not an option.

Thanks.

Default Color Temp

Ja and Jsslifelike has your exact model and would be better adept at helping you. However, have you tried changing the color temp to "cooler" setting? I have the 26HF85.

I've used the settings that ja2935 gave me and I've been very pleased with the PQ of the set. Here's what he posted:

You might find that you need to increase the brightness for some SD stations to about 50 to 55.
Are your other settings anywhere in that ballpark overall? This the first HD set I've owned, so I can't say how bright it actually is. The cool temp thing may work if you can maybe take the tint a bit on the red side. But you're right- your black white levels shouldn't be like that. I'm not sure about the service codes- I'm too scared to mess with them. If you can't remedy the problem, you may wanna take a loss, dump the set for like $500, then put that toward a brand new 85...

Yes it is in cool mode. The picture is actually quite nice for HD with:

Contrast: 100
Brightness: 20
Color: 42

If I decrease the contrast, it is too dim. If I increase the brightness, the blacks turn grey. My main question I guess, is will I damage my set by keeping the contrast up and would it be stupid to bump up the available contrast in the service menu?

Default Note Jsslifelike's settings

Note Jsslifelike's settings. His contrast is set to 65/100. Mine is about 28/50. Should be around 40-60% approximately. A new TV should be broken in slowly especially CRTs and Plasmas to allow the phosphorus to age slowly kinda like a new car. Unfortunately it sounds like you need a replacement set which should be done while it's under warranty. Setting of 100% on the contrast is not normal.

The components give me a little bit better levels. Optimum settings are:

Contrast: 100
Brightness: 35
Color: 42
Tint: R3
Sharpness: 35
Temp: Cool

Everything looks absolutely FANTASTIC at this setting.

Bringing contrast down to 65 makes it too dim for HD signals though. I am thinking that maybe I am just used to high contrast from my old TV (?). Is it possible that it is just a matter of preference?

Default Try a DVD with THX optimizer on it

If you have Star Wars III or any DVD with THX optimizer on it, use that to adjust your contrast. This gives you a more objective method to do it. Could you turn the contrast down to 80-85%? So you don't burn out the phosphorus. I had my old TV (non-HD) with the contrast turned all the way up for 3 years but once I went HD I read that the contrast should be about 40-60% and intially I have to admit it seemed dim, but now my eyes have adapted. The EYE is a beautiful organ.

Is is at all possible that someone(salesman or rep) turned the contrast down for some reason via the service menu? I dunno why the hell they'd do that(to promote a brighter, more expensive set maybe?) but it's worth a shot. Do you have or can you get the factory reset values for the service menu at all? Hopefully it's that simple...

It is very interesting that the settings I posted some time ago work for other people with the 34HF84. I picked them up from another BB and double checked with the DVE disc. It suggests to me that Toshiba is pretty consistent with the range of menu operated settings. My conclusions are either your set is in fact damaged OR you prefer a much brighter picture than many people! I do not believe a store would actually alter service menu settings.

I had and have again a Toshiba 30HF85 but that's okay, I already figured out how to get into the service menu after some more websearching, but thanks anyway.

I've actually decided to try and return this one as well, if Sears will let me. This one has an annoying weird problem where the color convergence is awful (about a 4 set displacement of horizontal screen pixels/lines at times), both in certain areas, but especially with certain color transition combinations which actually occur everywhere. I think this phenomena is actually two things going wrong, not one. The problem that occurs everywhere is not normal, I think.

With white text on black, I also get another weird phenomena. The colors actually appear to converge perfectly in most areas (the global color convergence is seemingly unaffected by the transition between white and black) but what I get is two sets of blurred double-image white texts, which are displaced from each other about 2 scanlines in the *vertical* direction, and thus get a funny blurred thick white text with gray outlines on top and bottom. Weird.

I'm gonna return this one too, if Sears will let me without charging a restocking fee...

Sears does not charge a restocking fee. You are fine.
