Hitachi Service Menu Tweaks

[Michael TLV]

The numbers vary from set to set.

Just tell us which temp you have selected and go from there. Select Standard ... then change the RGB stuff with the "S" following it.

If black background looks reddish in tint ... then reduce rcut-s or boost gcut-s and bcut-s.

i was wanting to know if the factory reset will undo any change that could have made in the isf menu and service main menu?
does anyone have thier orignal setting numbers or tweeked settings to get me back to being close. just as a referance before i try to undo and make any tweeks to end the red wash?

[hitachi stupid fool]

i will get the numbers later tonight when everyone gets to bed.
i do have just one more question can this be fixed easliy?

Easily fixed.

Put up a pluge pattern from a test disc. One that has 4 ot 5 gray boxes of varying intensity. Figure out where your red lies ... dark end or bright end ... and adjust accordingly.

Cuts for dark stuff and DRV for bright stuff.

It's just that simple.

okay just a stupid thought? can i use a thk optimizer for i have not recieved the test disc.
i know i really screwed up and should had not tried this. i thought i was careful by writting down the orignals.

but here'sthe number i have as of now without any success.

sub-bright= B9
white balance
STANARD
g drive (std)=35
r-drive (std)=3E
r cutoff (std)=3A
G CUTOFF (STD)=66
B CUTOFF (STD)= 3F

WHITE BALANCE
B/W
G DRIVE (B/W)= 4B
R DRIVE (B/W)= 4D
R CUTOFF (B/W)=7F
G CUTOFF (B/W)= 7F
B CUTOFF (B/W)= 7F

WHITE BALANCE
HIGH
G DRIVE (HIGH)=28
R DRIVE (HIGH)= 2E
R CUTOFF (HIGH)= 28
G CUTOFF (HIGH)= 5C
B CUTOFF (HIGH)= 6D

WHITE BALANCE
MEDIUM
G DRIVE (MED)=37
R DRIVE (MED)=31
R CUTOFF (MED)= 34
G CUTOFF (MED)=2D
B CUTOFF (MED)=90

NOW I TRIED TO ADJUST EACH WITHOUT ANY LUCK. FOR I CAN'T SEEM TO FIGURE OUT HOW TO MAKE THE TV TO SWITCH BETWEEN MODES TO SEE THE PICTURE AS I'M DOING IT. HOW WOULD I DO THAT?
THANKS

In user mode ... pick standard color temp ...

Now enter service mode and adj STD values and you will see the changes as they happen.

Michael,

i been working on this boo-boo all night and think i got it close.
but i was still haveing RGB strong in dark back grounds. when i get one setting like on high close to being perfect as i can get it and switch to another it's either R or B being to strong in back grounds.

so i was wondering is this the best approach on doing the settings to make sure i'm doing it right or not?

first i set the color to orignal preset settings. (black off)
then,
set standard before going into service menu.
then,
i select standard, and try to adjust to the best picture.

now my question is once i'm done with standard setting's
do i half to exit than re-enter service menu again to do high, medium,and b/w each time?
or while staying in service mode adjust each one at the same time without leaving? do i half to enter through standard first? is there a way to balance all setting at basically the same time?

thanks
james

Adjust only the mode you want to use. Adjust it until it looks right to you. Then use it. All other modes look wrong ... leave them alone. YOu need proper equipment to set those other modes up or else you make it all the same ... what's the point?

I've already given you the procedure for eyeballing your grayscale. Just go do it.

Michael,

i once again will thank you for your help. i stood up all last night and did what you suggested to do. that's how i got close as i did. so i did go do it,but still have questions! atleast i tried? if i done something to insult you i don't no where i did so and i appoligize and thank you for all the help you done so far and your advice has help in great detail.

i already feel like kicken my a** for buying a used tv. and leave things like this alone and leave it to the pro's.

but can you please explain why the med,high,and b/w cannot be adjusted the same way? for i do have it close by useing the gray scale you mentioned.
now far a good thing i'm learn what things does and how to relate to them.

any suggestions on the black issue? or maybe fixing contrast/brightness tweaks?

thanks
james

Michael,

did a little more and getting better.

but on a little back ground on the tv (51F510)it was just mention from whome my wife purchased the tv from stating it was so called tweak before or better yet messed with.
so i already had my hands full. my wife got it for $250.00 which i don't think it was a bad buy or is it?

Question is ... what exactly are you trying to achieve by screwing around with high ... medium ... b/w. Each one is there to achieve a certain purpose. B/W for black and white films. How are you supposed to set that without proper instrumentation? Do you even know what B/W means and what the goal is? Ditto for medium ... ditto for high.

Standard is what is supposed to be correct ... and you are adjusting it to be correct to your eyes.

Medium is bluer ...

Higher is bluer still ...

Ask yourself what you are trying to achieve. It's screwed up from the factory anyway ... it was never correct to begin with. Are you trying to set it so that you can sell the tV to someone else?

From an accurate grayscale perspective ... standard is supposed to be correct ... everything else is wrong. You just want to make the others into what? Certainly not "correct" because they are not supposed to be correct. They are wrong ...

Medium might have been 2+2=8 ... and High was 2+2=12 ... What difference does it make if its 2+2=6 now... and 2+2=14 ... it's still wrong and you are still not supposed to watch TV using those settings.

Leave them alone ...

You fix contrast and brightness with test discs. DVE and AVIa have the appropriate patterns for brightness and contrast. use them.

Michael,

to answere the million dollar question is, i understand what your saying about how med...high....b/w... is about to a point.
i never was the one that screwed it up in the first place!!!!

i also know i'm in over my head on this and need things explain as to a dummie!!!!

the price was right and i figured i could get a little advice from people.
far as how ...med... works i understand it makes white's more white!
high.... is about making white's more a warm color (pinkish)
b/w.....to be honest from what i know helps makes b/w picture more true, if i been mislead on the b/w please correct me!

now i know i should buy all the test disc which i would if i can afford them.
what was screw up was how the stand...high...b/w....,and med changed!
high was adjusted with way too much red. ...med.... to much blue... whole screen was blue.... no white's...which i did what you said but only had a thx disc for gray bars and adjusted it as you stated to do so. as i did the the same for..... standard...... med.....b/w.....!

i understand that the different setting changes flesh tone and white's.
my only problem is the black's is too black flesh tones look good in all settings now they change as they should. it's just the black is still to dark. plus there is a contrast or brightness circle glow in the center of screen. now is that a normal thing of is there another adjustment that someone else screwed up before me?

i admit i'm stupid and like things to be explained a little more suttle as i have made a achiement so far on a $250 hitachi vrs $1500 on a 2005 model
thanks

I never said you were stupid. I am simply questioning why you are doing this. This is not being done to get a better image. It is being done because it is some pet project.

High = bluest ... not red. Med is less blue ... STD is just right ... B/W is for B/W films ... but only if you know what B/W films are supposed to look like. (more red).

I am trying to help you to attain a more accurate image ... the frustration is that you don't seem to care and your attention wanders off to things that have nothing to do with the goal.

I won't help teach you about calibrating TV's ... you will have to figure that out yourself. Start by spending $20 on a test disc. That will help to fix your brightness and contrast ... assuming it can be fixed at all.

There may be a reason why some TVs can be had for $250.

Regards

i want to learn all i can and willing to be a student. this is not a pet project of mine. and the wondering might have a little to do with frustraightion over this. i don't feel like wasting $250 on just a pet project along with countless hours of adjusting things very carfully as you descibed to do!
but how can i learn if i can't ask questions. surely even you had to ask someone for help.
and no matter what the reason for the tv is for, things is well past that and i need help! just maybe i'm asking before doing what you say just to make sure things don't get worst! surly i think you should respect that. i already admitted things shouldn't haven't been done, but that's to late now.

also i stated earlier i have the THX disc but no classes! i asked if that would work with out no reply other than slight insults. and this is a thing my wife got me into and never wished to be apart of. but that's to late now. so just answere questions as best as you can with detail and understanding.
thanks
p.s.
maybe the wondering you suggest might have something to do with my cancer drugs i half to take!!!!!!!
