Hard to say...I just leave mine a 540p for DVD's as there is no visual difference to my eye. 1080i from an HD source does not cause the problem as the Hitachi's scaler is bypassed when receiving 1080i.

Oh, that is a different problem altogether. The Hitachi scaler cause a slight flickering at the top of my screen when VirtualHD is set to 1080i. Like cnjvh mentioned, switching to 540p solves this. If I feed the Hitachi a native 1080i (or externally scaled to 1080i) signal, there is no flickering.

Guys thanks for the reply, unfortunatley I didnt get the extended warranty. Would you suggest getting an ISF certified adjustment and see if that fixes the problem, or haul it to a certified Hitachi dealer. Is it too late to get an extended warranty, have had the tv a little less than two years.

I set the virtual hd to 540p, I am going to watch it for a while and see if this resolves the problem. If the scaler is the problem, can it be adjusted or does it need to be replaced, or should i even bother with replacement and leave it at 540p.

I don't think the scaler issue is something that can be repaired - I think its a design problem. I would just leave it at 540p. It's not worth getting a tech to tear into your set over it especially with no warranty IMHO.

I got 5yds for my 51". I still need to install it though, and I forget how I determined I needed 5 yards.

I think the cheapest place I found was here - http://store.yahoo.com/cinemasupplies/duv54rolx50y.html

Some ISF calibrators would be able to diagnose the exact cause of the problem, but I doubt they would be willing to fix it. This is typically a job for a Hitachi authorized service center.

I am seriously considering this myself now that my display is out of warranty.

I can't seem to find a copy of the 51SWX20B service manual. The place mentioned earlier in this thread doesn't have it. Anyone know where to find one?

There is not much useful info in the SWX service manual (you are better off getting the S500 SM). You can order them from www.servicemanuals.net

Thanks for the offer, but I'm getting the service manual electronically.

I'm just interested in reading up on all of the pieces and parts on the inside. I don't think that I'm going to do anything too drastic since I'm a novice.

I did take the screen off and cleaned the inside of the set, did the manual and electronic focus, but I can get a professional to easily fix any drastic problems I create there. I'm just tinkering a bit.

I've got the extended Circuit City warranty, so I'm not feeling particularly bold.

The few questions I have are:

Some folks talked about removing the "anti-glare" screen, while another said he just reversed the assembly and reinstalled. I'm surprised that he didn't have any problems considering that the "anti-glare" screen does a nice job of reflecting lots of light. Any thoughts on this?

Also, when I had the screen removed, I noticed some debris in the guns (past the plastic outer lens). Any recommendations on how to access and clean them?

vr,
Jeff

I think there's "H Position" "V Position" listed on the first menu that comes up...

It looks like there's "H-Posi" setting under the TA1360 settings...I'm not sure what the difference is.

Yeah, there's "H-Posi" and "V-Posi" under the OSD settings, too.

Can anyone point me to where in the service menu I can see/adjust the overscan? Have a 65F710A and am very much a newb, all I've done (or plan to do for now) has been the 117 manual, and gone into the service menu to center the screen position....I would like to tweak the overscan however but don't want to fowl anything up as I'm very pleased with the PQ after a few weeks of adjusting the settings for both life and image.

Derek -

You can reduce overscan by shrinking the geometry in DCAM. Just bring each line in a couple of clicks. Use AVIA or something similar to see how much overscan you have.

Derek,

If you're feeling a bit more adventurous, there is a set of two pots you can access via the service panel that will adjust overscan. I will do this to my TV over the weekend, as I am affraid to screw up my geometry with the DCAM method. Old AVS overscan thread

I think it should be a similar setup. I will let you know my results after I try it with mine. I am trying to reduce the horizontal from 5 1/2% to about 3 or 4%.

Thanks,
Jonathon

What do you need to adjust to make the picture sharper? Can the picture be out of focus?

Try this thread, which has some users setting for the 820:
New Hitachi owner, and question about vertical banding

Also try this one, which has a lot more posts to dig through:
Hitachi VS810 Owner's Thread

Finally, try the Display Calibration forum, which has much useful info on tweaks.

Good luck

Ok, I have two questions: First, turned on television this morning and picture was normal for about 1 minute then BANG I have a double image where one is red and one is green. Performed Magic Focus but had no effect. Turned it off and waited and turned back on. Came back on with same thing - it clicked back after a couple minutes to a good picture again but then went right back after about 15 seconds to the green and red issue.

First question: Is this something that can be adjusted through the service menu and second question: how the heck do you find a qualified t.v. technician - I don't want to go to Sears or some place like that and Hitachi's website doesn't work relative to telling me what authorized technicians are in my area (you get "page not found" - that's real professional for a huge corporation....).

I love this T.V. and it is just coming up on being 5 years old - it has given great service and an awesome picture especially in High-Def mode....if I have to layout some cash now to fix I don't mind I just don't want to go through a bunch of bozos before I find someone who actually knows what he is doing !

Anyway, any suggestions / advice gratefully accepted !

Rich

Rich,
I have a 57Swx20b and have also had this happen to me. I noticed that when it does happen my STB is tuned to an HD channel. I don't know if it has anything to do with the problem. What usually works to fix the problem is to power every thing down, wait a few minutes, then power everything backup. I also noticed that this only happens when my TV is hooked up using the DVI input, I didn't have this problem when I was using the componet input. Let me know if you get anymore info about this.

I think I'm having the same problem. I have a 57swx20B. I love this damn tv. My son was watching TV and then it suddenly glitched to a yellow/blue picture...like double vision. On ESPN it had the score with another score in blue right below it. I'm also wondering if there is anything I can do in the service screen...if not, who should I call. I have a extended warranty with Circuit City but I believe it has run out (still chasing down that receipt). Not sure if it was for 3 or 5 years.

Any help would be appreciate. Thanks.

Tim

I own a 51F510 and want to know if there are RGB contrast/brightness controls in the service menu. I can only find the cut/drive controls. If anyone know please explain where to access it.

Also, the image vibrates when fed 1080i DVI to HDMI from my Oppo player. Goes away @ 540P. Anyone experiencing this?

cuts=brightness

...well, for 51SWX20B anyway. Should be true for yours too.
