Mitsubishi TV - 52" Unisen Immersive Sound LCD TV: Model LT-52153


New 2010 Mitsubishi:
Here is a first look at one of the new Unisen Immersive Sound televisions from Mitsubishi.

The Unisen line expands on the 149 series offered last year from Mits. The principle behind these sets is that they not only offer great pictures but combine them with a powerful on board sound system without the need for additional electronics or speakers. They are available in three trim levels 151, 153, 249 series. Available in 40, 46, and 52" sizes

First impressions:

Out of the box and even before you plug the Mits in it exudes the feeling of a premium product. The thin bezel and clean lines make it a very attractive presentation. New this year is a glossy screen that gives it more of a plasma like look opposed to the mat finish that was used last year.


While most TV manufactures are trying to hide their speakers Mitsubishi is putting them right where they belong, up front. It has been a consistent complaint from my clients that the on board speakers from most of the manufactures sound thin and don't voice dialogue well.

The back of the set is plane but well laid out with connections being easy to reach and well spaced. Being in the custom integration business one of the first things that I look for is to see if all the inputs are accessible when attached to a wall mount. I know this sounds basic but you would be surprised how often this has actually been a problem and not just from the tear two manufactures the big guys have done it too. I'm happy to say that the Mits passes the wall mount test.

By the numbers:
The 153 has the usual features that you would find on a TV in this price point. It also has some pleasant surprises. There are four HDMI inputs, One USB for music or photo,1080P 120Hz processing, and a smart input management system that only enables the inputs that are physically connected to a device.Then there are the surprises. An integrated 16 speaker sound bar, dedicated subwoofer output, direct IR input, auto calibration microphone for optimizing the sound for your room, and a digital coax audio input for adding digital audio from a none HDMI source. I was very pleased with the feature set available on this TV.
The experience:
Once we got the Mits connected to our Sony BD player and our HD Dish Network system it was off to the races. Initially like most TV's out of the box the Mits was way over driven. Using the THX optimiser disc that we have around the store we were able to quickly get the Mits into shape and looking good. The color control system that Mits uses is far superior to most on the market; allowing you to adjust six separate color and their tint. These settings are set per input allowing for separate optimal settings per source. While the picture was very pleasing with good color, decent black levels and low noise the real story here is the sound. We paired the TV with a paradigm 8" subwoofer using the TV's subwoofer output and put it through its paces using a Blu-Ray version of Top Gun.
It was immediately evident that this TV has some serious audio chops. Even without running the auto calibration setup the sound was dramatically superior to most $500 home theater in a box systems. It only got better once we calibrated the system for our room. Paired with the Paradigm woofer the system had plenty of impact to fill a small to medium sized room. Now I'm not going to say that this system sounds better than a nice component based surround system but considering the ease of use, the cleanliness of the presentation, and its retaliative performance I think its a great value. I would however definitely recommend adding a subwoofer to the system as we did here. Without the sub the sound is loud but defiantly lacking the bass impact the we all associate with home theater.
The Bad:
I did have a few gripes about the TV. First off the factory remote has horrible button spacing and is a pain to use. Second Mitsubishi's menu system (they refer to it as Jade & is a new system for this model year) is cumbersome to use and not as responsive as we would like. Third the subwoofer output on the TV is way to hot, meaning that you have to turn the gain way down on your subwoofer to keep it from clipping.
The Verdict:
All in all this is a very strong product that offers a great value when you consider the sound aspect. If your somebody who is looking to do a modest homtheater system on a budget I would have no hesitation recommending The Mitsubishi 153 Unisen TV. Its combination of sexy styling and performance make it a real contender in today's crowded TV market.

Plasma or LCD???

This is still probably the number one question I get asked from people who are shopping for a new TV's. The truth and politically correct answer is that both technologies when executed correctly can produce good pictures, but here is the real answer. Based on how the two technologies render color, motion and gray scale plasma in my opinion still has the upper hand in most cases. While LCD technology has been getting better and better each year I still have not seen an LCD that can compare with Pioneer Kuro displays this includes the so called LED TV's that have hit the market recently.



That being said plasma still isn't the answer for everyone. Below I will answer common questions and clear up some misconceptions that people have about these two technologies.




Plasmas don't last as long as LCD TV's: False. While different manufactures will have slightly different numbers both LCD's and Plasma TV's of comparable quality should have similar life expectancies. Most LCD or Plasma TV's will list a life span of 60,000 hours with some newer models boasting up to 100,000 hours. That means that if you watched TV for eight hours every day it would take about 20 years to reach 60,000 hours. That's not to say that these TV's are guaranteed for 20 years but the light source that generates the image for these sets is engineered to produce a reasonable amount of light for this time period. As we all know sometimes things don't go as planned and not every one will get the full 60-100,000 hours out of their TV.


Plasmas need to be recharged: False. Plasma panels are a closed system and there is no need or way to "re-charge" the plasma.


Plasmas Burn In: True. Plasmas can experience image retention or "burn in". This problem occurs when a constant image or pattern is left on the screen for an extended period of time. While the frequency of this problem has become less and less throughout the years, under the right conditions burn in can occur even on newest of units. It has been my experience that the less expensive plasma TV's are more susceptible to this problem then the more premium units. I have seen several entry level Samsung's develop mild image retention on our show room floor from the repetitive video loops that we run in the store. Luckily most people are not watching the same one hour video clip over and over again for eight plus hours a day. It has been my experience that under normal consumer TV watching conditions burn in is not a problem I would worry about, but if you are a hard core gamer or like the idea of using your TV as a giant digital picture frame then you may want to look more closely into LCD products.


Plasma uses more power than LCD: True. Plasmas do consume more power than LCD, but over the course of a year it only adds up to 40-60$ more annually over a comparably sized LCD. A small price to pay for superior picture quality I say!


LCD TV's do better in bright location: False. This is less of a cut and dry answer, because both technologies have problems with high ambient light conditions but they are different problems. Plasmas issue is glare. Because the plasma panel is made of glass it does reflect light. All manufactures treat their glass with a proprietary coating that helps reduce glare, but none of them are perfect and you will still get some glare regardless of the manufactures claims. LCD on the other hand suffers from a different problem. The issue stems from one of the core purposes of the LCD substrate (panel). The substrate is engineered to spread light evenly across the panel to give it uniform color, and to elevate hot spots from the back light. The panel does the same thing with light coming in from outside sources as well. So instead of glare the image tends to get really soft and the color washes out. Neither problem is good and the best solution is to invest in some good window treatments to help reduce the ambient light in the room. The other option is you can move out to Oregon, because as every one knows all it does is rain out here anyway.

What are the advantages of LCD? LCD has some good things going for it. First of witch is variety. There are definitely more options when it comes to LCD TV's versus plasma both in size and brand. So if you have a specific dimension that you need to meet you have a much better chance finding in LCD where sizes typically go from 19" to 55" from most major manufactures. Plasmas on the other hand are typically available in 42" 50" and 60" sizes. The second and third advantages are power savings and "Burn in" resistance. We covered the last two benefits in more detail previously so I wont elaborate further.

What are the advantages of plasma? Plasma when we talk picture quality has several advantages. They can reproduce more colors and over a wider viewing angle, they have more life like movement, they have deeper blacks and they are readily available in sizes exceeding 55".

So now what?: So now that you know some of the facts it's time to go shopping. Ultimately you are the one spending your hard earned money, so you need to physically put your eyes on your prospective sets and judge them for your self. I always recommend bringing a DVD or Blu-Ray that you are familiar with so that you have a reference point when you look at different models. Regardless of what I or any other reviewer say you need to make the call. As always I encourage you to buy from a Authorized dealer who is going to stand behind there product well after the sale is done. Most of the time the cheapest price is not always the best deal.
