What is a rear projection TV?
A rear projection TV is a type of display technology featuring a CRT, LCD, or digital light processing (DLP) projector inside the chassis which projects an image on to the front-mounted screen. It was popular during the early days of now-traditional LCD TVs, where LCD technology was prohibitively expensive.
What to do with the plastic rear panel from the TV?
The plastic rear panel from the rear projection TV. Picture: Anthony Hartup.

Do rear projection TVs have tubes?
If a very large screen size is important to you, look into rear-projection televisions. These sets don't have the same size constraints as direct-view televisions because they don't use the cathode ray tube for the display. Instead, they use a projection screen.
Do rear projection TVs have input lag?
Yes, the projector has input lag, or latency.
How long do projection TVs last?
Newer projector technologies, however, either help expand a projector's life span or completely eliminate the use of a lamp (and filter) altogether. All of these newer technologies have a life span of 20,000 hours or more! Either way, with these new technologies, there's less maintenance and cost!
What are the components of a projection TV?
Many electronics are manufactured with components containing lead, mercury, cadmium, leaded glass, copper, flame retardants, beryllium, and bisphenol-A. A projection TV is a television set that uses a video projector to display its picture.
Can a TV projector be rear projection?
A projection TV can be either rear projection, making it function like a standard TV set, or front projection, which works like a movie projector. -- Our Everyday Life.com. These components aren't exactly earth-friendly materials, so that's why recyclers shy away.
Can you dispose of old projection TVs?
In case you've not had the experience, many charities and disposal facilities won't take certain electronic waste, including old projection TVs. The reason is simple enough, but it's certainly frustrating. Many electronics are manufactured with components containing lead, mercury, cadmium, leaded glass, copper, flame retardants, beryllium, and bisphenol-A.

Can CRT tubes retain power?
CRT tubes can retain power after the TV has been unplugged. None of the old TVs and monitors I have dismantled in these articles have retained power, but I always discharge them anyway.
The Victim
Precautions
- CRT tubes can retain power after the TV has been unplugged. None of the old TVs and monitors I have dismantled in these articles have retained power, but I always discharge them anyway. I have a quick guide to discharging CRT screens here.
Tearing It Down
- Other than the plastic rear cover, this unit is made from timber and held together by self tapping screws with 6.4mm bolt heads. This is a refreshing change from the usual plastic cases we tear down. Most of the waste from this project can hopefully be reused for extra shelving in the cave. The timber is a mixture of MDF and traditional chip board....
Circuitry
- There are ten individual circuit boards inside this unit. The main board is packed with heat-sinks and large capacitors and resistors up to 10W. It also harbours the high-voltage transformers, or flybacks, that fire the CRT projectors. The next board (pictured below) has fewer components. Of interest to me is the EPROM chip in the bottom right corner. This chip is reprogrammable and co…
Other Useful Parts
- As with anything containing CRT tubes, there are deflector cones. These contain pure copper. There would be over half a kilo of the precious metal here. Don't expect to get rich from one TV, but if you teardown enough TVs and monitors you could make some money from the copper. The screen consists of two pieces, an opaque layer inside called a fresnal lense, and a clear layer out…
The Waste
- As I mentioned earlier, most of the case for this TV are made from MDF and chipboard. These materials are perfect for garage shelving and many other applications that don't need to look good. The sides of the case are MDF. The rear panel is the only substantial part made from plastic and I can't help thinking this could be usefull for some purpose in its current form. It looks like it …
My Favourites
- Voltage regulators
Nearly all of my projects require some form of voltage or current regulation, so I am always on the look out for power regulation chips. I salvaged four 780x CT chips from this TV. I have been using LM317 chips for power regulation to this point and they work incredibly well. See how to build a… - MOSFETS and transistors
MOSFETs and transistors allow you to rapidly switch large voltages using smaller, signal-strength voltages from a micro-controller. I salvage many motors from printers, etc, and I currently use cheap H-bridge type motor controllers to run these. I've started building my own higher-capacity …
