I have a quick question (for such a long-winded post) about resetting the TV since I've never had the need to do a factory reset in the 13 months I've owned my 65JS8500, but I may now have to do so following my latest firmware update. Question: Will unplugging the TV for a given length of time accomplish the same thing as going through the TV's factory reset menu option (MENU > SUPPORT > SELF-DIAGNOSIS > RESET)? The E-Manual states that the latter will reset everything to factory defaults except for network settings -- does simply unplugging the set from the wall outlet for X amount of time accomplish this too, or is it not as thorough of a reset (or not a reset at all)?
I hate like heck to go the factory reset route, but I think something might have gone awry during my latest firmware upgrade on June 14. I updated from an ancient year-old 1221.7 firmware version to the latest 1455.0 via USB (only reason for me wanting to perform this update was for the HDMI 2.0a capability Samsung released around November of last year to support the new K8500 player I'm thinking of buying), and following the update I immediately noticed that the picture was much darker with some black crush I'd never experienced before, and that some colors appear a bit overly saturated. With prior firmware updates, my set would reboot just once, but with this update it rebooted twice, with a 10-second or so delay between reboots. Just before the second reboot, the TV was fuzzy, reminded me of the good ol' days of rabbit ears and weak signals; I had a sickening feeling that the set was hosed, but just before the second reboot I saw that the activity light on my thumb drive was flashing, so I knew the TV was still accessing the drive and doing "something" with the firmware files on it. After the second reboot the PQ was greatly improved vs. the initial reboot, to my huge relief. All of my prior settings were retained except for my default audio delay of 0 -- the firmware reset it to 100 -- which was a simple fix. But the TV looks a lot darker overall now than before and some colors (especially red hues) are now on the over-saturated side, reminds me a bit of torch mode on store display models. Some cable channels are better than others, per usual, but I'm still not getting the overall PQ I'm used to (unfortunately I don't own a DVD player or gaming console to test other sources, just my Motorola QIP7232 DVR from Frontier Communications (formerly Verizon) which I rebooted to see if that would help, which it didn't; the cable is running directly from the OCM to the Motorola DVR, there is no intervening A/V receiver in the video mix since my old Pioneer receiver has no HDMI inputs and is strictly used for audio via a digital optical audio cable connection). As a matter of fact, when now viewed slightly off-axis (about 2'-3' from the left or right edge of the panel bezel), the TV looks like it did when viewed head-on prior to the update (weird!). But with this latest update, the head-on view is significantly darker and, for lack of a better description, has an "over-processed" appearance. I've fooled around with every conceivable picture setting the past 10 days, tried the Reset Picture option, and also searched for/found/tried the settings posted by forum members denpom, ERuiz, prme19, and King Richard (I prefer Standard mode, and feel that denpom's was the most suitable for my bright room), but things still look darker overall than before. I retained my backlight setting of 12 (tried 10 but it was too dark) and even though raising it beyond 12 does boost the overall brightness, the blacks in certain scenes still lack definition/detail, albeit they are now much blacker than before ("inky black" as denpom describes his). My initial contrast setting was at 100, but bringing it down to 90 still doesn't help provide definition to darker scenes.
I realize I'm in the minority when it comes to this latest 1455.0 update, everyone else has reported excellent PQ results from what I've read here, so I guess I'm the lucky one. As for what I plan to try next, I have a new HDMI 2.0 cable on order (I read that this one works good with the JS8500 and the K8500 player: http://www.amazon.com/HDMI-Cable-6ft.../dp/B00NQ9OQU2
) since my current Belkin braided cable is at least 8 years old (http://www.belkin.com/IWCatProductPa...duct_Id=441602
) and was rated at HDMI 1.3 at time of purchase. Moreover, the E-Manual recommends using a "High-Speed HDMI Cable" or "High-Speed HDMI Cable with Ethernet," so I'm hoping the newer cable might improve things when it arrives next week. I have not yet tried a different HDMI input on the OCM box since I thought I'd run this factory reset question by everyone first before crawling behind my AV furniture, plus the Sammy Set-Up Guide shows that set-top boxes should be connected to "HDMI In 1" on the OCM box.
Member "denpom" refers to those who see PQ improvements from firmware updates as experiencing the "placebo effect," but in my case I must be experiencing "reverse-placebo syndrome." Oh well, at least I planned ahead and wrote down all of my prior settings
But those settings are no longer cutting it after this update, and I can't seem to get this thing dialed in to an acceptable level (the TV has looked freakin' OUTSTANDING for the past year), so I hope a factory reset -- or something less Draconian such as the new cable and/or HDMI input swap -- does the trick. Other than that, I guess I just have to wait for another firmware update and see if that helps things look closer to the way they did before.
