2008 Samsung DLP's Discussion (HLxxA650/A750) - Page 74

Yes - you are right... it only scales up to 1080i. The set is still deinterlacing. I must have been thinking of the Apple TV.

BTW the Harmony issues was fixed, apparently Logitech just added the TV to the DB in the last day or two since when I did it they didn't have the inputs or codes.

does anyone have a working 10% off CC online code that i could use to buy this tv today? thanks

To give an update, I did bump my contrast to 95 to give a little extra punch. And during the day with bright sunlight coming into the house I bump up the Dynamic Contrast to LOW and the LED Control to HIGH to combat the sunlight. Otherwise at night, those settings give a very rich and accurate picture. I watched another Blu-Ray last night and it makes me love movies again.

If you are talking about the 750 the codes have been there since at least the beginning of April. One day soon after I got the set the model wasn't even recognized, but when it was it was there a day or two later it was there with discrete codes and all.

So I'm intrigued about what has changed in the last day or two for you. . .

The 650 codes weren't there for me, I never put in a 750.

Since I see a lot of people still considering purchase... I have a 61A750 for under $2k from CC. It will not fit in the back of a Chevy Tahoe standing up. I laid it on its back (screen up) to make it fit, while still fully boxed. It is extremely bright and PQ is truly amazing when using some of the calibrations listed previous. Extreme improvement over what I saw in the store. PS3 and Time Warner HD DVR box both connected via monoprice.com HDMI cables. Firmaware wass upgraded using the download available here. No power cycle or any other abnormal behavior. COD 4 is amazing on this. No lag in game at all. I have been using 'Game' setting. It is probably too bright for some games but it works well for COD on the darker maps. No bowing on the top. VERY slight hourglass when watching 4:3. I would buy it again in a heartbeat! Could not be happier!

Please don't take it as a fact that the 650 is better, brighter, etc, etc vs. the 750. People here are only giving their opinions as nobody has reported any comparison of the two under any sort of controlled conditions. Without any of the following conditions, the assertions are anecdotal:

-controlled environment (not "big box" showroom)
-(ISF) calibrated sets
-expert or experienced opinion

Note that anecdotal doesn't mean false or without merit (or conversely true), only not proven to an accepted standard.

Well said, Failsafe...

How did you get the Tivo HD to get to 1080P, on the box it says it goes up to 1080i only, no "P"

Thanks

Figures, I see that someone already posted this, sorry.

hey all just got my 750.... no black flakes, no bowing at all ( to the naked eye havent checked grid ) i likely just got lucky... havent done the firmware update just yet but i will soon...

also i want to add i got this for a total after taxes of 2173.49
If you go into the store and tell them you want the 10% off that you can get online, they should give it to you, but they only do that off the internet price, so i think they took 2299, 10% off that then tax.. sounds maybe right... or if they were dumb they did store price of 2199 then 10% off and tax

either way im very happy with this, but in dynamic mode, i cant seem to find the area in the menu where you can change the LED level etc, if its in tv details it seems to be grayed out for me not sure why...

i was tring to fix a small tilt in my 61a750 but cant find the tilt screws.When i went up to tv and shifted it the picture moves slightly.Being new to rptv i was like wow when it moved the tilt was gone.So i think with a little gentle pressure to the tv bezel in right spots you can minimize if not total get rid of any tilt.

Can anyone tell me what are the little black dots you see in rptv pictures?Are they dead pixels or debris?And is it rare to have a clean screen with none of them?I seen alot in stores at freinds etc and all had like 2 plus black dots.The tv i got has none just wondering if i lucked out or maybe the ones i saw with the dots are rare.

It depends... in general though if the black dot is the exact size of one of the "pixels" then it's probably a dead mirror (in RPTVs).... but if the the speck is larger or smaller than any one pixel... then it's probably dirt or dust.

It's hard to really explain it unless you've seen both.... then you'll just know.

Well... I picked up my HL61A750 yesterday... and I LOVE it. It's TONS better than my old Mits WD-52525 that was junked out through the Best Buy performance plan... so I basically got the new set for free (minus another $400 for a new performance plan).

This is of course my opionion... but I played with both last years LED and this years LED and I could make either one look great... or bad vs the other one.

Also... although I'm sure this TV isn't as bright as a NEW bulb... I think it's plenty bright enough when you're not pitting it against other sets on display... once it's in your home you'll be happy. In fact, I'd say that most will NOT like it on the birghtest settings once you have it in the house... so I'm not sure where all these "brightness" arguments are coming from. My understanding is that the LED is rated at 60,000 hours before it's at half brightness... if you're lucky you'd get what like 1,000-2,000 hours on each bulb before half brightness? At any rate I'm already running the LED on at about half bright just because it is so bright so when things get alittle dim, I'll boost it up again so I would say I'll probably get over 90,000 hours of this set (assuming no major issues come in in that time).

I put the grid up and I lucked out with only some very slight bowing... I'd say less then 1/16th of an inch from top to bottom or side to side... my biggest "problem" is my lower right corner... I think though that the problem is that the screen just isn't seated right so once I get annoyed enough I'll open up the case and press it in some more. I also have very little "convergence" issues... basically you only notice if you're 1ft away fromt the set AND have a grid up, lol... but I don't watch grids.

I've updated to the latest firmware and so far have played around 10hrs of 360 via HDMI at 1080p... I've also watched a few movies at 1080p/24 with no issues... and I've watched a few DVDs/HD-DVDs at 1080p/60 with no issues. ((I have an HD-A35 HD-DVD player)). I've also played a little bit of Wii at 480p with no issues... all these go through my Onkyo 605 AVR btw.



I'm still not sure how I like my settings yet... I'll probably run through DVE on HD-DVD tomorrow and get things a little better.



A few quick questions though... how do I enable the advanced settings in the service menu? Also... I (by mistake) disabled something in the service menu... I think it's like the 5th item down (I'm at work and can't remember)... something like Noise Reduction or color monitor??? (the option below it said "wide", haha)... at any rate, I can't turn it back on lol... anyone know how.... or even what I'm talking about, lol. I tried factory restore but that didn't do it either.



Overall.... would I buy the TV again? yes... would I buy a second one... yes... would I pick another TV over this one... probably not, as I didn't. Do I wish it was laser... sure... or maybe OLED... sure... but this set will hold me over until the next "great" thing shows up.

TK.

so it seems there is some slight bowing when the black bars are on the right and left... but its at max 2 little tick marks of the tape measure.. not sure what that is, but basically its hard to tell and doesnt distract me.. other than that, no issues this is my 750 btw

EDIT: i agree with it being too bright at night, i put the LED down to high or med cuz it literally hurts my eyes, and thats WITH room light on.. i saw someone post that i thought htey were nuts.. but seems they were right

guys i know a new 650 bulb is brighter but isnt the color deeper,more vivid looking and less washed out on the 750?btw the 750 imo owns i had the 52xbr4,It was garbage next to this smeared like crazy.

My understanding is that LEDs have a larger color gamut over bulbs so... yes they do have a deeper color... but will you notice?... hard to say.

Where do you go to get a FW update and how is it done. Picking my Sammy HL61A750 up tomorrow at CC.

Bill

bill, its really easy... you DL it from the samsung website, its an exe, you unzip it into your flash drive, it creates a folder... then just plug it into your tvs usb slot... go into the menu and find SW update or something like that, then it searches for it and auto installs....couldnt have made it easier...

hey guys i just noticed this... i have the 750 running through my receiver, its the onkyo sr674... and it seems to be downconverting all 1080i signals from cable tv to 720p... and wiht my last LCD it wasnt doing this... and if i hook it up straight to the tv, it displays in 1080i, anyone have any ideas about this? 1080p passesthrough the receiver just fine though...

My setup is doing the same thing... my cable is running via component to my Onkyo 605.... I'm not sure why though. Either the Onkyo isn't upconverting or my settings are messed up... haven't looked into myself.

Also... can anyone tell me why when I turn off my TV I lose sound from my HD-DVD player as well... but I still get sound from my 360 and PC? All my hardware goes to the AVR first and then into the TV via one HDMI input. I know it will sound funny, but I sleep on my couch a lot (not for being in trouble) and like to turn off the TV, but still have the audio going from my favorite TV shows. I could do this with my old TV via HDMI, but now my new TV I lose sound???

Lastly... can anyone give me any tips for getting one to one pixels for my HTPC setup?... I'm currently going through the VGA connector, but I could do a DVI to HDMI input as well.

Thanks.

The Onkyo 605 down converts 1080i to 720p over HDMI. I dont think they supported 1080i until the 606.

I'm guessing you are using component inputs from cable to the receiver? I believe that Onkyo (I have the 805) when it upconverts that component to the HDMI output, it will scale it to 720p, (it's max). It shouldn't do anything but pass through the signal if you connect it via HDMI.

There's still only four feedback listings on Amazon. Let's leave some and help bring some new blood to AVS.

Looks like the price dropped down at the Big River.

That is not correct. It is fact that the 750 has a 450CD brightness while the bulb set 650 has a 650CD brightness. This is out of the samsung service manual so not only is it brighter but its a lot brighter.

You can also see the review for last years set (6187) where it basically says the LED doesnt touch the usually high rated Bulb models.

Where did you find the "service" manual? I could not find it listed on the "Samsung Parts" site.

You do realize the 650's bulb typically loses 20-30% of its brightness within a couple of hundred hours? Then remains fairly level until it drops to less than 50% of its original brightness down the road.

A good article covering some of the other advantages...

http://www.soundandvisionmag.com/inn...ht-engine.html

"There are many advantages to using LEDs instead of conventional lamps in DLP rear-pro sets. For one, LEDs are more reliable and last longer. Where the bulbs in conventional lamps cost several hundred dollars and need to be replaced every 3,000 to 5,000 hours, LEDs last about 120,000 hours — which means you can expect them to last for the life of the TV. LEDs also don't wind up in landfills like spent conventional bulbs, and they don't contain the hazardous substances (such as mercury, xenon, or metal halide) found in arc lamps.

Also, while bulbs require a warm-up period, LEDs turn on instantly. This not only allows the picture to appear immediately with full color and brightness, but (when properly synced with the DLP chip) can also help improve contrast and picture quality. And the simple optical design of PhlatLight LEDs, which use a single emitting area per color instead of an array of small LEDs, allows for shallower cabinet depths.

But maybe the biggest advantages of LEDs are in color reproduction and brightness. Because individual LEDs are used to create the primary colors, they can produce a wider, richer range of colors than sets using a white-light bulb and filters or color wheels to split the light into separate colors. For example, the PhlatLight PT120 chip set used in the Samsung RPTVs can produce about 40% more color than traditional lamp-based sets, according to Luminus. They can also help reduce or eliminate the visual artifact known as "the rainbow effect.""

I have one on order from Samsung
