Official Sony KDL-46HX750 & KDL-55HX750 Owners Thread - Page 29

Still a edge led with frame dimming only. Same 240hz panel. Noticeable change is that it is now passive 3d rather than active! This allows for ps3 simulview, but isn't that a downgrade?!

edit: To Danjen: 4 pairs of passive with the W800 (dirt cheap-ish), and 2 pairs of active with the W900.

edit2: for completeness, the HX850 is now the W900 (same edge led with local dimming), and the EX640 is the W650 (120Hz ed led panel, no mention of dimming or 3d).

edit3: Looks like W650 is 32" only. I guess a lot of EX640/45 owners with issues are gonna get an upgrade to W800 (HX750 equivalent) for any hardware swaps. Gotta assume that the R550 is replacing the BX450 and the EX440.

It really seems apparent to me that EX640 is no more. We only really have:

W900 - previously HX850
W800 - previously HX750 / edit: EX640
R550 - previously EX440??? Can't be 640, since numbers always go up, not down.

oddities:

W650: 1080p 32" - spec not seen since EX520 when it was 60Hz
R400: 720p 32" - EX340?

edit: let's call a spade a spade, the HX750 has been eliminated, and the EX640/45 is now the W800. Only thing that makes sense. Rationale: EX640 and HX750 already shared the same ambiguous "frame dimming". No uprade path between EX640 and W800. And almost most noticeably, the lack of active 3D. The HX750 didn't lose active 3d, the EX640, just GAINED passive 3D.

I was in a situation of warranty replacement of an EX520 which had onscreen-guide, x-reality engine, and wifi-direct and they would hear nothing of it when trying to replace with an EX640 that had all those features gutted. Two representatives went as far as saying "no sony tvs have guides anymore, that's been phased out".

I'm guessing you're running Media Center, "flickering on and off" is just plain intermittent "flickering", and the problem occurs only on 1080i channels. If all that is true, you are almost certainly experiencing the 29/59 bug, and the answer is to disable dynamic contrast in the video driver control panel.

I messed a lil more with it today and it won't work on 1920x1080 it will only work on the lowest setting ( can't remember off top of the head ) , but what Im left with is a tiny square in the middle of my hx750 ?? Every other resolution the screen turns on , then off constantly , and there's a weird colored swirl kinda thing going on in the background . I'll try to post some pics or a short vid if I can soon .

If this isn't what you're trying to do, disregard

like unscrewing the screws in the back panel and tightening them not too tight or even taking the cover off and doing it on the LED module screws?

or anything else to that matter? let me know thanks!

okay i wont.

any idea on how to help the corner edge bleeding then?

I hate it when I hear people having those issues not only with the HX750 but with other tv's as well because the tv's should be checked for these issues before they leave the factories. For as much as people pay for their tv's now days they should check them, its only right because if they did it would resolve these issues among other things. A bunch of B.S if you ask me and I can thank my lucky star's that I dont have any issues with my tv knock on wood. This is an issue because manufacturers are more worried about quantity then quality and 4K these days when what they should be worried about is making the customer happy because without us they wouldnt be crap!!!!! Anyway let me know if any of the suggestions I gave work or not. Good luck.

I already have the kdl40ex640 so is it worth it to pay $400 more for the kdl46hx750? Thanks!

It's probably more cost effective to simply replace flashligting sets to purchasers that complain (small percentage, but probably growing as consumers become more savvy), rather than filter out every flashlighting set that get noticed during qc.
