Projection TV Repair Gainesville FL

As this article went to publishing it was reported at HD Library that Panasonic is providing a $1,000 USD rebate and one member found this projector for $2,749 USD. This is nearly half the price of projectors that can do better and taking all of its performance points into perspective this price level definitely hits the bang per buck category of entry level gear representing great value!

Starting with the PT-AE700 720p projector, Panasonic has built quite a reputation around their extremely wide installation capability and inexpensive pricing using transmissive LCD technology for the last couple of years. Panasonic continues their 720p capability with the PT-AX100 while introducing new 1080p24/60 capability in the form of the PT-AE1000U for a mere $4,000 USD street price, which is expected to get even lower as the months pass. This has certainly been the year for new 1080p front projection below $5,000 USD.

Transmissive LCD projection technology is well over a decade old using red, green and blue LCD panels. No color wheel is required and therefore no concerns over rainbows; those are a DLP issue only related to the size and expense of 3 chip capability as well as supply and demand of the devices. In the early days fill factor of the pixels was quite large, creating a screen door effect that could not be missed with less than 8 screen heights. In this area transmissive LCD has improved by leaps and bounds, becoming one of the hallmarks of the Panasonic line; no pixels to be seen at even unreasonably close viewing distances. This technology does come with one thorn though that has yet to be tamed, natural dynamic range. To produce black, transmissive LCD has to block the light trying to pass through it, which remains difficult and results in a poor black response. Transmissive LCD also takes a hit in peak light output due to inefficient pass through losses of the LCD panels. This absorption of light, regardless of image, also requires the LCD panels be constantly cooled lest they or their neighboring optical parts suffer a melt down.

One way to improve dynamic range is to employ an auto iris and manipulate the gamma response. Most call this a "dynamic iris". Many are using this technique to enhance the viewer's perception of dynamic range while also improving spec numbers for higher contrast ratios. For a proper ISF calibration, the feature must be turned off or the numbers will never make sense; the feature changes things that much. Many transmissive LCD products use this process to create a competitive perceived dynamic image. ...
