    i think it should be the same as the other models which is

    press the info and mute button at the same time. remember to write all settings down before u change.

    what do u think of this set?

    i'm getting it delivered this week as a replacement for 32x25 (100hz) found it too blurry without the didital circuit on and effects similar to phillips p+ when it was on.

    i could'nt live with it, the wife liked the camcorder effect though:rolleyes:

    i adore mine if it helps, though the lack of contrast worries me and i am sorely tempted to go for a philips 6557, a sony ls60 or a tosh zd26.

    Too much choice, all i care about is picture quality. I swear, if i could change the contrast on my JVC i would never part with it.

    have you tried raising the contrast level in the service menu?

    this can be done on my 32x25 by pressing info and mute then number 5 which are the V/C settings .the contrast can be altered on each of the tint settings from -16 to +16.

    have you had a look in the menu and tried yourself. just note what its set at on the contrast range, has it got this in the menu of the 32r25?

    i tried before. Adjusting anything other than brightness and hue whilst using RGB does nothing at all. I really wish i could change the contrast, i would love that. I wanted a tosh zd26 originally but now i'm scared to part with the JVC as the picture is so good. I could actually say that it rivals my FS76. In fact i think i prefer the 50Hz image on the JVC!

    Jac, can you adjust the contrast on the x series when in RGB??

    astobilla,
    i see what you mean about contrast level. ive just been to comet and had a play with the settings .

    it doesnt seem to have as high a range as the 32x25. theres no detail in the dark areas. dont know about contrast and rgb on 32x25 as ive got a pioneer dcs-303 hooked up with s-video connection, it can be changed on this it seems.

    this has put me off getting the 32r25 set now.

    just rang sound and vision, bolton about it and they have said i can change my order for any tv.

    just dont know what to go for now, ive got 750 to spend on it.

    any ideas of a set in this price range?

    No mate, no idea - Sorry. I'm in the same situation.

    I will say though, i don't think its a case of the JVC being too dark, i just think that black is too black on it. If you look at the bright areas on screen they are fine, also it has the best colour handling i have ever seen.
    I have only ever used Sony TVs and this JVC (which is for a second room) really is making me consider getting rid of my FS76 because the image seems terrible compared to the JVC and a tosh 220 DVD.

    I have 3 models in mind now, a sony ls60 and tosh zd26 and a philips 6557. All i care about is image quality. I am very tempted to keep the JVC and live with thte dark areas, because i would put money on me never getting the same levels of geometry, picture quality and convergence.
    If you see anything interesting let me know.

    Bill

    i have thought about it, but it looks horrible - especially after having the JVC.

    I keep finding myself drawn towards Philips. I had a 9607 for a few weeks - the image quality was un believable, but it wobbled at the sides with NTSC material :confused:

    yeah the panasonics do look a bit unexciting.

    i was thinking of a phillips set myself before my jvc but the p+ put me off. agreed the picture can be awsome but the processing faults :thumbsdow .

    thats why im tempted by the 6557, its 50Hz, looks nice and and has no pixel plus!

    However, the ls60 seems to have a lot of admirers on these pages - some of whom had JVCs previously. I just wish i knew for certain if the pic was better on the ls60.

    theres a review of the phillip 6557 in the feb issue of what video and tv.
    it wins the best buy award.

    ratings were out of 5*

    picture ****1/2
    sound ****1/2
    features ***1/2
    ease of use ****1/2
    value ****
    overall ****1/2

    their only gripe is the shimmering aura around fast moving objects on a digital channel. they say this happens with most digital tuners and isnt much to worry about.:nono:

    sounds the same as p+ to me

    pixel plus was more of a heat haze around moving objects, and you know what i could have lived with it. Like i said, it was the wobbling with R1 dvds that annoyed me.

    Where is Squirrel when you need'im to tell us how the ls60 pic compares to his old JVC??

    i'm quite happy to go through all the various models until i'm happy - but i reckon unbeatable would come out with their Bill beating stick and give me a thrashing of a lifetime!

    I still wonder about the tosh 28zd26 - i mean the ZT got cracking reviews and the picture i meant to be something else - add to that component in and the ability to switch from 100Hz to 50 Hz which i dont think the sony can do.

    its a nightmare is this.

    access by pressing info and mute . hey presto the menu pops up.

    to alter geometry you need to press number 4 def on the 32x25 ,should be the same on the 32r25.

    my settings for you to compare are:

    1 v- shift -002 moves pic up or down
    2 v-size -001 squashes or heightens pic
    3 h- cent -022 moves pic left or right
    4 h size -031 widens pic to fill full screen
    5 trapez -014 tilts picture forward or back
    6 ew - pin -041 pincushion for left and right sides of screen
    7cor pin 0000 pincushion for for corners
    8 cor up 0000 pincushion for top corners
    9 cor lo -009 pin for bottom corners
    10 angle 0003 tilts the pic left or right probably what you need to adjust for horizontal lines
    11 bow 0001 bends horizontal left or right
    12 v-scr 0000 seems to stretch pic top and bottom
    13 v lin -007 seems to move pic up or down


    write your settings down first then go through the video tests on the thx optimizer .

    you almost certainly will notice that the various boxes and lines are out.

    these can only be adjusted via the menu in full screen mode so you will have to exit the menu and check other screen modes you use the most.

    i got the lines at the edge of the screen almost perfect in full screen mode and then checked the others.

    to make an adjustment use the left and right arrow it will only alter a setting if you press store.

    its not too difficult ,this is my first widescreen and the first i knew of service menus. geometry on my set good apart from a slight inward bend at the top corners which i cannot straighten.any way this set going back because off tinge in the bottom left corner and im not impressed with the 100 hz processing

    thinking of the 32zd26p for 850 as a replacement

    hope this helps
    jac

    ive just remembered this set has a picture tilt. this may be enough to staighten your horizontal banners. it should be on the features menu. try this first.
