As for the set itself: even if this TV were perfect, if I had to do it all over again, I"m not sure I would. The screen is VERY glossy and reflects a ton of background lighting if you have other lights on in the room. The viewing angle is also pretty poor, although while in the store, it had the best viewing angle I could personally assess. It may just be that edge-lit LED LCD TVs (or all LCD TVs, for that matter) simply suck when it comes to viewing angle. The images on the screen itself look pretty good.

One other note, the prices quoted here are ones that were found while cruising online retailers. They could vanish in an instant or you may find better deals if you dig. Also, I am concentrating on 1080p LED LCD TVs because they dominate the larger screen sizes.

I immediately replaced the t-con and mainboard, but the symptoms stayed the same. I later found the t-con board clicking (relays) multiple times after power-up, corresponding to the screen flickering. Disconnecting the LCD ribbon cables stops the clicking from the t-con board. I think this means that there is a short in the LCD panel itself.

One note about black level depth on the KDL-70R550A is that they look jet black on the top and bottom bars in a 16:9 format mode when directly viewed front and center. However colors can be a little more washed out on the picture itself due in part to the anti reflective coating on the screen of the R550A.

Sometimes dark shadow detail could be better in the KDL-70R550A as the screen filter (matte screen) on this TV causes a hazy appearance with some programming on the screen. One quick fix is to turn up the Brightness setting some. This will cause better definition in dark areas but at the expense of less penetrating blacks.

This feature working in conjunction with the 120Hz panel can distort the natural background blur in the picture somewhat in movies or film-based content so use with care. It"s great for sports programming though. Options within the setting are: Clear, Clear Plus, Standard, Smooth, Impulse. We recommend turning it off for movies, and using the Standard or Smooth setting for other programming.

A very good comparison for the KDL-70R550A is Sharp line with which Sony is trying to take some market share. The 70R550A sells for around $2498 putting it very nicely in a value-plus area in the price per square inch category. It has a reasonable feature set to go along with the size and we particularly like the passive 3D. The Sharp LC-70LE757U and Samsung UN65F6400 are good comparisons.

On the other hand, competition is fierce. The Sony R520/R550 can"t quite match the picture quality of the cheaper Vizio"s E1i-A3 can"t match either one for picture quality, it"s cheap enough to also deliver better overall value than the Sony. On the other hand, the R550/R520 out-styles both, culminating in a package that makes it an easy recommendation for anybody who wants a little something extra in a well-priced big-screen LCD.

When Sony first pitched the R series we were told it was the "workhorse" of the 2013 TV lineup, and that"s about right. The edge-lit LED backlight lacks the excellent local dimming and Triluminous technology on higher-end models like the KDL-65W850A, so there"s little expectation of similarly premium picture quality. It also doesn"t have the so-called "dynamic edge" dimming of the

Sony is touting RVU compatibility on the R series, although for some reason step-up 2013 Sony TVs don"t have this extra. Through it, "DirecTV customers with the Genie Whole-Home HD DVR can access their set-top box, DVR, and on-demand services right from the KDL-R550A TV without the need for additional equipment." Sony assured us that DirecTV doesn"t charge an additional fee, monthly or otherwise, for the TV to access the box. For more info, check out DirecTV"s support page for more; we didn"t test it for this review.

If you"re using this screen for gaming, then enabling Game mode will reduce the lag to 31.9 milliseconds which is a "Good" result compared to other flat-panel TVs. The Sony W900 and X802A scored significantly better,

There are five greenish tabs on the left side that seem to be glued to the panel. The third one from the top down seemed to be the what with the problem as the screen would go crazy as soon as I applied little pressure on it. The first and second ones from the top down where somewhat sensitive but almost unnoticeable. The two bottom ones did nothing to the screen when I touched them. In addition to the five green tabs, there is a brownish ribbon with a connector on each end which seem to connect the top and bottom. Nothing seem to jabbed when I tapped either end of it.

I wanted to get your thoughts on what the next step should be. Will I have to remove the left tabs? If so, what is the best way to do it? Will have to remove all five tabs plus the brown ribbon? Also should I pull the tabs from the end connected to the front of the LCD panel or from the end that connects on the side, or from both ends?
