Hitachi C47-WD5000

Recommended Posts

The 5000 is also made in China.

I have not seen a 7000, so I cant be sure it is as good as a 5000, but they most likely are.

Get em while they last boys, cos there on a run out sale.

I have owned the 57” 5000 for over a year and am considering purchasing a 47” for another room before they disappear.

Regards,

Owen

I paid only $2370 for this beast and I have to say it one of the best purchases I ever made.  If it weren't for Owen's comments on this forum I probably wouldn't have given it a second glance in the store!

Was that new? If so, can you tell us where?

It was floorstock from JB Hifi in Osborne Park, Perth. I was a bit uncomfortable about taking stock from the floor, but with the money I saved I got a five year warranty. It was only $200 extra and put my mind at ease somewhat.

You can play around in the user menu as much as you like, but you will never get what I consider a top class picture.

Edge enhancement cannot be disabling in the user menu, and the colour adjustments are next to useless.

The service level manual convergence is MUCH better then the Magic auto convergence system.

...

Owen

Even though I'm happy with the auto-focus and can't seem to notice the edge enhancement, I must admit the colours on the Hitachi are getting to me. If I got my hands on the service manual is it difficult to adjust the colour levels without specialised equipment? Would it be possible for you to post your own colour settings here so that I could enter them in?

It is VERY difficult, if not imposable to adjust the grey scale (colour) without instruments.

You can do a reasonable job by eye if you know what you are doing, but you can also get yourself in trouble if you don’t.

My setting would be useless, as I have done so many adjustments and modifications away from standard on my Hitachi.

When I can find the time, I will write a guide on how to adjust grey scale using basic, commonly available equipment.

Getting the convergence perfect with the service mode manual adjustments does not make a huge difference for SD video, but for HD, the difference IS huge.

Edge enhancement on the Hitachi is about the worst I have seen. I don’t know how you can’t see it.

The picture as delivered, is quite hideous, mostly due to Velocity Scan Modulation (edge enhancement).

It’s really noticeable on computer text with a HTPC, very ugly.

Unless you have seen a CRT RPTV working properly, it is difficult to understand just how good they can be.

the 7000 has a setting in the user menu called "vm-on or off",i wonder if this is the edge enhancement,also hitachi is having a run out on the 57&47 so get in quick,apollox jb hi fi cannington has the 47 for 2400&57-2700,i think i got the last 57 but the 47 is still available.cheers stubbey.

The 5000 also has that setting in the user menu, but it only tuns the VM down, but in no way does it turn it off.

To do that you need to get into the service menu and disable it for each seperate input mode.

Get on to this mob and get a service manual, you will NEED it.

http://www.hcsd.com.au/

You can hire one for $20, so don’t even consider not doing it.

There are over 600 numbered, not named menu items in the very unfriendly service menu, and the 7000 may well be different to the 5000.

You will need to send me a copy of the menu listing so I can compare it with the 5000 before I could advice you on what to change.

PM me when you are ready.

It is dangerous to blindly fiddle about in the service menu so don’t do it.

Regards,

Owen

top buy stubby, I feel a little ripped on my one now, was yours a floor model?

I wonder how much diff the service menu is, as hitachi havent released a service manual for the 7000 as yet! :blink:

a little off topic the new sony 60" grand wega kfws60s1 , looks sensational, just wondering if anyone knows what the replacement cost of the 3 globes for this beast will be? and any thoughts in comparision to the hitachi 57"

Don’t worry about the cost of replacement lamps with LCD or DLP RPTV’s. It will work out at about $100 per year and is not significant.

The big Sony LCD looked good the only time I saw it in action and I would say without question that it is better out of the box then the Hitachi CRT RPTV in most respects.

The Hitachi CRT models are not good as delivered and require service level adjustment to give an acceptable picture.

However if the Hitachi is fully tweaked, no current LCD or DLD RPTV can compete for overall picture quality. Analogue still rules for large RPTV’s.

The Sony LCD could be improved with the installation of a neutral density filter to improve black level performance at the expense of a reduction in maximum brightness.

I’m quite impressed with the Sony CRT RPTV’s, in particular the 46”. Out of box performance is quite good with accurate colour and little edge enhancement evident.

There is no doubt that the Sony would benefit greatly from calibration, but they require much less work then the Hitachi’s which is a good thing for the average customer.

well I finally got my 7000, ran all new cabling through the roof to where I wanted the new set to be, and finally set it up. I can see what everyone means from the picture quality, its very average, but I was expecting that, and I'm letting it run in and will do as owen has suggested earlier once hitachi release a 7000 service manual. I do have one noticable problem, which I am just wondering if others had the same thing, the bottom few 50mm of the picture seems to be missing (as in it would be displayed below the bottom of the screen) this is only noticable when there is any type of text along the bottom of the screen, you only can see the top half of the text.

I will have to replace my screen, as my lovely 3 year old decided to play race tracks with his hotwheels car and has scratched the crap out of it. When I rang for a replacement, they only have screens for the 5000 model, as no 7000 models are available as yet. They think the 5000 will fit, but just want to know if anyone can suggest whether this is worth while doing, I was also thinking of 6mm laminated glass instead but again I dont know if this is viable.

or what can I polish the scratches out with, they are not deep, more like abrasive scratches with only a few visable when the tv is on

any ideas, anyone

What size mode is the TV in?

The stretch mode will increase size horizontally and vertically and create the situation you describe.

Don’t worry about the picture quality. It will be fine after calibration.

Sorry to here about the scratches on you screen, but all is not lost.

The screen is acrylic and can be cut back and buffed in the same way as acrylic car paint.

Minor scratches will come off with some cutting compound followed by swirl remover to give a mirror finish.

More serious scratches will require the use of very fine wet and dry paper (used wet on a sanding block) followed by the above.

It’s just like working on car bodywork.

Owen

Owen,

I've had the WD5000 for well over a year now & have applied most of the mods you've mentioned (Yes, I have the service manual!)- A couple of questions though.....

When you raised the crt platform, did you observe any change in brightness uniformity across the screen (ie. brighter in the middle)?

And, you mentioned there may be another setting (other than the APACON & VM) to reduce edge enhancement - There is still more than i'd like to see (APACON is 0 for all modes & VM is off)!

Thanks :blink: , Tom...

Gday Tom,

No, raising the CRT’s did not affect brightness uniformity noticeably but it sure stuffs up geometry and requires quite a bit of work to get back to normal so there is a limit to how much you can raise the CRT's.

Edge convergance is compromised if you go to fare.

On my 57”, brightness uniformity is very good with no noticeable hot spot in the centre.

Lens stripping is required to get good colour uniformity.

With APCON = 0 and VM off you should not have noticeable edge enhancement.

What are you using as a source?

What is you Sharpness setting?

Owen

I have 3 main sources:

-DGTEC HD Box via component

-Sony Progressive DVD via Component

-Foxtel Digital via S-Video.

All seem to display edge enhancement to some extent - most noticeable on the edge of peoples faces - very hard edge - Sharpness setting has minimal impact...

Interestingly, I ended up finding another service menu setting which reduced the trailing edge (ie. white to black) enhancement - but if I reduced that to zero - it looked odd having leading edges sharp & trailing edges soft! Don't have the manual with me, so can't remember which setting it was :blink: Needless to say, I set that back to where it was (more or less).

But it's that setting which prompted me to believe there is still some edge processing going on despite turning other parameters off.

In any case, I think I might raise the CRT platform by around 50mm & see how it goes... Did you end up keeping it at 70mm higher?

P.S. Thanks for all the advice you've given over the years!

Tom.

Hi Tom,

I also seem to remember some other setting that affected edge enhancement but I can’t remember what it was, and I have not written it down on my work sheet, so maybe I am imagining it.

There are no documented settings that seem relevant.

If you can remember what it was you adjusted let me know and I’ll have another look at it.

I did leave the CRT’s raised by 75mm, but that is definitely as fare as I can go.

At 50mm is easier to get geometry and convergence correct.

The 47” model may not respond in the same way to this mod.

I dont have any noticable edge enhancment on my 57".

There are separate edge enhancement adjustments for every input mode of the TV and not all are documented in the manual.

I can send you info on the none documented ones if you want.

I don’t have my worksheet with me, so I cant remember what the non documented ones where for.

Many DVD's and free to air TV have edge enhancment "EE" applied

Regards,

Owen

Hi Owen,

I also have the 57", & would be very appreciative if you could send me that info.

I'll try & find out which setting I found (can't remember if it was a documented or non-documented one...).

I must admit, after doing the mods & tweaks, the picture is now excellent !! Although - IMO, if I could get rid of that last bit of EE (apart from what's being transmitted of course), it would be even better!

I've painted the inside of the cabinet black, but it still seems somewhat reflective - Have you used cloth all round?

Also, have you considered blacking out the edges of the lenses as recommended on some mod sites?

One last thing I noticed (FYI) - the electrostatic focus points are slightly different depending on the input mode. I now always focus with a 1080i input. - Could never understand why my HD inputs looked a bit soft!

Regards,

Tom.

YAY!!!

Finally got my service manual for my 7000 model

Owen I hope you dont mind me bugging you over the weekend about certain adjustments I will want to make.

I know it might be slightly different from the 5000, but I'm hoping its not much, and I can finally improve the output quality on the screen

oh and btw, the pc input on the 7000 series imho, is really a waste of time at only 640*480. what were hitachi thinking.

I wonder if there is someway of getting to accept a higher res some how?

I’m not sure how much I will be around on the week end, but bother away dude.

It would be helpful if you can scan the pages that show the service menu items and there purpose and email them to me.

I will PM you my email address.

I can’t see why the VGA input would not support the same timings as the Component inputs.

I just noticed that the 7000 is now listed on the Hitachi site as being "Discontinued"!! That was quick!

They no longer sell a 57" CRT display! & have gone for a replacement 43" & 50"!

Hi Apollox, I also have a 7000 model and tried High Country a while back and they advised they did not have a Service Manual for the 7000.  Where did you get yours?  Thanks.

Hi Owen. The VGA input seems to be fixed to 640 x 480, which is absolutely useless. I bought a DVI-I to Component convertor for my PC over the net, which although has a bit of overscan using a couple of the standard Windows resolutions, is a hell of a lot better than 640 x 480.

hi newby,

sorry I havent been checked this forum for a long while, I actually got it from High County, they got them in. so give them another go, if you havent already done so.

I still havent done a thing with it yet, just havent had time, I will scan the service menu in soon though.

Owen, I'm still going to bug you soon, just need to find the time away from work and the family to get my butt into gear.

on another note (off topic I know) whats a good transcoder to use for a HTPC to component, and/or is it better to go for say a 6600 or 6800 Nvidia as I heard they have component out. does anyone know if this is correct?

Matt
