Recently my superb 10 year old (2008) 61" Samsung high definition (1080P) Model HL61A750A1F Solid-State DLP-LED television (that never needed any repair in ten years) began developing "white dots" as the solid-state DLP projection chip slowly failed. It's common for DLP chips to develop microscopic white & black dots after several years of use, but to have a DLP solid-state television for ten years with virtually no repairs is extraordinary, imho. The DLP projection chip is about the size of a postage stamp, the actual imaging area of the DLP chip is about half the size of a postage stamp. The DLP chip engineering is extraordinary, a DLP chip has hundreds of thousands of microscopic mirrors embedded within it's surface that "switch on or off". The high definition television image is created by the mirrors of the solid-state DLP chip and magnified with high quality glass lenses onto the 61" screen.
However, after several years of use the DLP chip's microscopic mirrors begin wearing out and individual mirror elements begin locking in the "open" position, creating "white or black" dot (s) that are then projected onto the viewing screen. The "white & black dots" appear randomly anywhere on the screen as the solid-state DLP chip slowly fails.
Over three weeks, the "white dots" on my TV began appearing slowly, one at a time, along the upper right side of the screen. Then more "dots" appeared in the upper center of the screen which were more difficult to ignore when watching a television program.
When I purchased the 61" Samsung in 2008 ($2,000.+) I liked the new DLP solid-state engineering and the superior picture quality but had no idea how long the new DLP chip technology would last. To have the solid-state DLP LED television operate perfectly for ten years, with no maintenance or repairs, is extraordinary. The Samsung DLP-LED 61" rear projection television is an outstanding product. IMHO, the DLP-LED 1080P picture quality is far better than LCD & Plasma televisions. Only the new (2018) OLED TVs are superior, imho.
Background information about DLP chips: In 2007 Samsung introduced the pioneering, superior image quality of solid-state DLP-LED projection technology which did away with what had been very expensive short life incandescent light bulbs that had been used in earlier generations of rear projection televisions. The new Samsung solid-state LED DLP chip in 2007 was, and still is today, of superior quality. The solid-state DLP chip with LED light processor doesn't need image convergence. A DLP video chip has little or no video picture registration alignment issues. The DLP picture provides true blacks with crystal sharpness corner to corner. With a DLP chip there is no picture motion lag when viewing television events such as sporting events. The DLP chip has no color image fringing around the edges of images, no picture image lag or retention and no backlight bleed around the edges (as can be seen on many LCD flat panel TVs).
The downside with rear projection DLP LED televisions, or nearly every projection television, is their slightly narrower viewing angle compared to a flat screen LCD, Plasma or OLED television display. The (2008) 61 & 67 inch DLP-LED Samsung Solid-State rear projection television has three HDMI inputs. Because new solid-state television research improves year to year, within a couple years after Samsung introduced their first solid-state LED DLP rear projection televisions they began making only flat panel LCD (liquid crystal) televisions.
In the summer of 2017, when the DLP chip in my ten year old Samsung 61" solid-state rear projection TV slowly began developing "white dots", I researched the repair-replacement costs. I discovered ShopJimmy.com could provide a brand new factory sealed Samsung solid-state OEM replacement DLP chip for about $180., that's about 1/4 the cost of having a television repair service company travel to my home to do the DLP-LED chip replacement.
The superior picture quality produced by the DLP-LED Solid-State chip, when compared to an LCD or Plasma TV screen, is why I decided to repair the older (2008) Samsung 61" television. BTW, the cabinet of the Samsung 61" DLP television is about 15" deep and the entire television weighs less than 70 pounds.
ShopJimmy.com provided an identical, brand new, DLP chip for the Samsung. I carefully read ShopJimmy's installation instructions, viewed their online DLP chip installation video and installed the DLP chip myself in about an hour. And now the picture quality of the Samsung 61" is like new! The innovative, solid-state engineering of Samsung's DLP-LED rear projection television makes DLP chip installation surprisingly easy. You don't have to be a computer or engineering expert to replace the DLP chip in the Samsung television. ShopJimmy's DLP chip installation directions and their online instructional video are both easy to understand. Thank you ShopJimmy.com ! read more
