The Hitachi UX21511 Enclosure at first glance is very similar to the Hitachi UX21513, UX21517, UX21518, and other Hitachi enclosures, but it’s different

The Hitachi UX21511 Enclosure uses lamp type LC37. The enclosure is made up of the following pieces:
External Sheet Metal Cage/Housing: part number: NA63991
Internal Sheet Metal: part number: NA72182
Plastic Shell/Cage: NT0455
Clip, holding down the lamp: NA63941

Here are a couple of pictures of the enclosure:

At first glance, this Hitachi enclosure looks similar to other enclosures reviewed on this site, but there are a few minor, but extremely important differences. All in all this enclosure is compatible with at least the following TVs:
50V500
50V500A
50VX500
60V500
60V500A
60VX500

Let us know if we need to edit this blog entry with additional compatible models!

So what’s different about this enclosure?

The rear "pull out" view of the enclosure is shown here. Shown with arrows, we have EX1) and EX2) .

In the picture above, you can see (EX1 ) that no visible hole drilled out on the Hitachi UX21511 Type A, however, on other Hitachi enclosures such as the UX21513 Type B, this area has been drilled out.

In photo3, we’re looking at the area EX2 (opposite side of the enclosure), which has been drilled out and is stamped with an "A"

Ok…but how do I know if my Hitachi Projection LCD TV has a bad lamp? How do I diagnose my TV in general?
Here’s a quick Q&A that might help…

Does the LAMP LED indictor stay on (solid)?
If yes, you probably have a bad lamp. Replace and recheck. If not lamp, your ballast is not lighting your lamp…replace that if still no power.

Does the LAMP LED indictor blink continuously?
If yes, than the lamp sensor door might be acting up…or you just don’t have the lamp cover in place. Without the lamp cover, your Hitachi TV will not power on. If you’ve never tampered with this cover, we suggest removing the lamp cover, taking out your lamp enclosure and visually inspecting your lamp. If it looks ok, without any bulges in the center of the filament or other signs of damage, replace the lamp enclosure back in place, tighten all screws, and carefully place the rear lamp cover back on. Check to make sure the lamp door cover is being activated.

Does the TEMP LED indictor stay on (solid)?
If yes, your TVs internal temperature is too high. Make sure there is decent ventilation on the back side of the TV. If the TV is in a sealed entertainment center, this could be the problem. Remove your TV from the current air-restrictive environment and try to turn it on again…if problem persists, contact an authorized Hitachi servicer.

Does the TEMP LED indictor blink continuously?
If yes, one of your internal fans might be malfunctioning. Check fan functionality. Remember it is normal that your TEMP LED blinks continuously until it cools down…this could take up to 3 minutes.

Does the POWER LED indictor Blink continuously (FAST)?
If yes, temperature sensor near fan is too hot. Allow TV to cool down. Do not unplug from the wall!

Does the POWER LED indictor fail to come on?
If yes, replace lamp.

Hitachi 55VS69 55-Inch LCD Projection HDTV

fixyourdlp — Thu, 13 Sep 2007 10:24:52 +0000

The Hitachi 55VS69 is a high definition television using the LCD technology and has a screen size of 55 inches when measured diagonally. With the use of the LCD technology Hitachi has managed to keep the set very compact and lightweight inspite of its huge size. The dimensions of the set are 50 ¾ inches in width, 34 ¼ inches in height and 18 inches in depth. The weight of the set is a measly 86 pounds which is quite commendable considering the size.

The Hitachi 55VS69 has been well designed not just in terms of the compactness but also with respect to the design and styling. The front of the cabinet has been kept clean and tidy with the channel and volume buttons located at the side with other inputs and outputs on the backside. The placement of the speakers inside the cabinet at the bottom of the screen has allowed the manufacturers reduce the width of the set by a precious few inches.

The set is cable TV ready with the inclusion of a CableCard slot which eliminates the need and the hassles to go for separate set top boxes. The native resolution of the set is 1280 X 720 which is sufficient for any input sources at 720p. As far as the performance is concerned the Hitachi 55VS69 is quite good (even though not the best) and is certainly worth a look if you are looking for a large screen size without wasting too much space.

fixyourdlp — Wed, 12 Sep 2007 11:35:17 +0000

The Hitachi 62VS69 is a high definition television using the LCD technology and has a 62 inch screen size when measured diagonally. LCD HDTV’s till now have not exactly been given the attention that is normally bestowed upon the other versions like the DLP or flat panel sets. But this set proves that the LCD technology will not be knocked out of the race so easily, as it makes quite an effort with some good performance and a decent list of features. The screen size is really huge and is an excellent option if you are looking for a big screen size for a relatively small size.

The Hitachi 62VS69 offers a native resolution of 1280 X 720 in which all the incoming signals are displayed at 720p. Hitachi has used a three panel LCD system in which each panel is used for red, green, and blue colors. One of the drawbacks of the use of LCD technology is the screen door effect. In screen door effect you can easily see the space between the pixels especially during bright scenes. The speakers have been intelligently placed inside the cabinet at the bottom of the screen which reduces the width of the set on both sides of the screen by quite a few inches.

The dimensions of the set are 57 inches in width, 35 inches in height and 19 ½ inches in depth. The set weighs in at just above 100 pounds. The set offers a good performance giving good colors although there is room for improvement as far as the black levels are concerned.

The three-line digital comb filter is used to clear any visual interference. The Hitachi 50VG825 also comes with a USB slot, which enables the user to view data in the form of photos or videos directly from the digital camera or pendrive.

The three way speaker system provides excellent sound quality. The remote has most of the features of the set and is fully illuminated which is a very important feature in case you have to use it in the dark. The set uses a user replaceable lamp which is said to have a life of 10000 hours which will last you for about a couple of years depending on the basis of daily usage. The set is also equipped with a CableCard slot, which enables the user to view cable TV without the need of additional set top boxes.

The Hitachi 50VG825 is priced more or less around $1500, which makes it a reasonable deal for the quality, and features it is offering.
