2008 Samsung HL61A750 LED DLP owners thread and FAQ - Page 297

Anyone care to confirm or deny seeing a faint 3 inch oval on the right side of the black no signal screen in low led mode ?

Deny. But I really don't pay that close attention to PQ on a NO SIGNAL screen!

No oval here.

Does this also show up on dark test patterns displayed from a USB card?

Do not try this at home!!!

Tell us why???

Did you, by chance, read post #8880? These are not theoretical problems. People screwing around in the service menu have experienced them and posted in these forums!

I have found a few things that help after unboxing... one is setting the menus to be semi transparent, the others are horizontal / vertical adjustment and Actuator Gain. Though it seems that the Defaults are within + or - 10% of near perfect... As my Actuator gain needed to be at 47 and Horizontal was a little left and Vertical was a bit low.

Also I was trying to speed up power on (TIVO, AVR and TV) and input switching with TV and remote. I disabled HDMI hot plug, so it will not automatically select an active HDMI connection when HDMI is already the set input. Also I adjusted the delays to shaved off 1.5 seconds, and keeps the info screen from poping up an extra time during power on after everything syncs. Before all the changes it took about 15 seconds to get the TV to show picture and sound from power on, and now it takes 10 seconds.

I disabled auto power on to keep the TV from powering back on when unplugged.

No but I see a light blue 3" circle with an i in it

that oval in question in behind the no signal message so you can't see it.
ok, yes, I'm a dork, sorry...I was at work and went from tired memory when I wrote the previous post..(hic)

But pause on an all black screen while watching a flick or use an all black jpg picture on the usb stick, or even use a computer with an all black screen, and you'll see that oval albeit very faintly..virtually under where the no signal blue circle with the I would be - I betcha.

Likely it's a internal reflection design thing..at least I hope so.

my new WD TV displays a mostly black picture on it's screen saver which is how I noticed it.

Thank you. There is a reason the Service Menu code is not included in the Users Manual. The SM is definitely not a place to act on your curiosity and make changes just to see what they'll do. Do a search and you'll find plenty of examples of why the typical user should stay out.

using a black screen saver from my wd tv

I'd imagine it'll show up with a all black picture or computer screen.

as I said it's hardly noticeable, and apparently quite common

Rear-Projection TV Turned into a Multi-touch Display

Regardless, I am very much looking forward to Lee's post about his SM settings. At the very least...the will be an interesting read. If you want to enter the SM you do so at your own risk and it should not be done unless you have an understanding of it's functions.

Exactly. And please also include the settings that we mortals can adjust easily (Contrast, brightness, sharpness, detailed settings, picture options etc.) in addition to the settings inside the service menu.

Lee the fate of everyones home theater rest in your hands. You hold the key to this threads survival because if you don't we will resume our regularly scheduled program: manufacture dates, stickers on the bezel, etc etc=).
J/K folks I understand these are important issues, but if Lees settings are good to go, I may not have to haunt this thread and spend more time enjoying my display.

Cheers

You may not, but there's always someone who won't read the FIRST POST of an FAQ thread and ask what the best setting are for this TV.

Agree. This is a "hobby," which screwing around in the service menu makes all the more interesting and fun. My point is not to scare folks out of entering the service menu but to ensure that they do so with the appropriate cautions in mind. The sugggestion in the post that prompted my list of screw-ups was just a bit too cavalier IMO. I also await Lee's input even though I do not have an A750.

To clarify service menu details... there are not many items you would not want to change as most of the items are for calibration. If you do not have the tools and do not know what does what, then stay out.

As for making adjustments, there are a few (5 items) that can be changed without cause for alarm. I have already stated them and though very simple they do make an improvement that can be reset to defaults if needed.

If you do play around... get a Service Manual (Page 1) it has some interesting info and can be had for less than $18.00.

I do agree that this tv does have a lot of Red gain... I assume it gets washed out in Dynamic Mode and or on sales display.

There is plenty to learn from this thread, though it is a bit cluttered, one should take the time and read through it. As receiving info already given is cheating yourself from actually learning and understanding.

I agree Service menus should be left to the pros... I have no sympathy for the careless and blind that attempt things beyond their capabilities.

Best Buy only lists on their website for samsung DLP the 61A750 and it is a outlet item. Is this the beginning of the end?

The beginning of the end was at CES when Samsung announced they were pulling out of the DLP market.

This is probably just a Best Buy thing. A BB sales manager told me that during one of their staff meetings they were informed that, as a chain all DLP sets would be cleared out by end of 2nd quarter 2009. He also mentioned it could happen months before that.... Those thinking we'll see great 2009 model Mitsubishi sets are probably living in a dream world and certainly won't be buying one from Best Buy. No retailer wants to carry these things so logically why would Mitsubishi, Samsung or any vendor still spend R&D and manufacturing dollars to build them? Best Buy will not waste shelf space or spend dollars on shipping/distribution for items that aren't selling well and have low profit margins.

Amazon.com is still stocking and shipping both 61 and 67" models and the 67A750 I purchased back in Janauary had a early 2009 build date meaning Amazon.com works with very low inventory overhead... If Amazon has it 'sold by Amazon' new in stock that means the Mexican factory where Samsung is producing these sets is probably still producing them... but the death watch is ticking as Samsung said 2009 will be the last year.

His Dynamic Black sm settings made me happy... For those still in quest to get the perfect PQ from these sets, it would probably be more beneficial if Lee (or someone with the know-how) would write up a how to do-it-yourself calibration guide. As many pro reviews have praised the out-of-the-box settings for these xA750 series, service menu tweaks really should be done on case by case basis... with a few exceptions, copying someones service menu settings will not yield the best picture in your environment in fact it could yield a worse PQ that factory settings.

For the last couple of days they have only been offering the 67" from their own stock, with the 61" only available from other merchants.

Agreed,

I want better PQ, I'll need a better source


Blu-ray 1080P is excellent
Most Games (720P) very good PQ

DVD (480i/p) very good to excellent (Up scaled)

SD channels- Looks good to OK (Stretched or zoom off)

HD channels 1080I - 720P PQ varies from very good to average. Depends on the the provider, time of day, broadcast feed, etc.. The list goes on.

Yes it is, I was told by a BB saleman they are getting out of selling dlp tv's this year.

That BB is getting out of DLP business may, if fact, be true. However, that a BB salesman validates it brings nothing to argument.

i have a 67a750 and my eyes gets strained when i see any type of medium motion (like someone walking into the room). The pictures seems blurred or my vision gets blurred. I know it is not my source or the size of my tv because it replaced a mit 65732. picture is very clear when there is not much movement. just wondering if anyone else have this experience or could it be a bad set.

That is EXACTLY one of my problems (among others). A tech is coming to my house tomorrow to look at it and I'll let you know what he says.

The first set I had didn't do that, so I know that's not something that should be happening.

I have the 61A750
