Our Verdict
The Sharp LE635U is a good budget TV. It is pretty basic, both in terms of design and functionality. The picture quality is quite good, especially in terms of the contrast ratio, but the viewing angle is quite narrow, and it has noticeable dirty screen effect due to its direct-lit backlight.
- Great contrast ratio.
- Limited viewing angle, with poor colors off-axis.
- Poor gray uniformity.

We buy and test dozens of TVs yearly, taking an objective, data-driven approach to deliver results you can trust. Our testing process is complex, with hundreds of individual tests that take over a week to complete. Most of our tests use specially designed test patterns that mimic real content, but we also use the same sources you have at home to ensure our results match the real-world experience. We use two main tools for our testing: a Colorimetry Research CR-100 colorimeter and a CR-250 spectroradiometer.

The center stand is quite stable. The dimensions of the stand are 19.5" x 13.5".
The contrast ratio is really great. The blacks will look nice and deep in a dark room.

The gray uniformity is always a bit more problematic with direct lit LED TVs like the Sharp LE653. The LEDs behind the screen create a grid, which produces the dirty screen effect.
The colors shift rapidly as soon as you move out of axis. You shouldn't buy this TV if you have multiple seating positions.
Update 01/06/2017: We have changed the methodology of testing. Since this is an old TV which we don't have anymore, we extrapolated the results from 2016 TVs.

Its semi-gloss finish doesn't reflect a lot of light, which is good if you have a few lights on.
It doesn't get very bright, with a maximum luminosity of 233 cd/m2. It should be good enough for one or two windows, but not ideal for more than that.
The input lag varied a lot on the Sharp LE653U LED TV, from 30 ms to 40 ms. It was more often than not in the mid-30 range, hence our 34.7 ms measurement. Overall, it is a good gaming TV.

This TV does get relatively loud, but the frequency response suffers as the volume increases. There will be noticeable pumping at higher volumes. The bass extension is rather poor.

This TV sounds clean at very low volumes, but there will be a significant increase in distortion at moderate volumes and higher. Especially in the Mid-Bass range.
