TVs usually contain a very small amount of gold that might amount to about $1.00 or less in value. It can be quite a lot of work to get to the gold inside your TV as well.
In fact, computer parts contain the most gold. It is possible to recover gold from computer boards; it is also possible to extract gold from motherboards, integrated circuits, contacts, pins and printed circuit boards.
Televisions are made of several different materials. Some of the most valuable components of an older CRT monitor are metals. CRT TVs usually contain parts made of copper, gold, iron, steel, and many more, all of which can be refined for the manufacturing of new products.
The cheap TV sets will use tin plating where gold might be used in the higher end TVs. Since gold does not oxidize in air, it is typically used on the connector contacts: the HDMI connector for one.
For over 100 years following its discovery, indium lay in obscurity perceived as uninteresting and of little use. Today, however, this metal is vital to the world economy in the form of indium tin oxide (ITO), which is used in the growing flat- screen TV and solar panel markets.
The minerals needed to make LCD screens are Galena, Quartz, Pyromorphite, Cerussite, Anglesite, Hematite, Cassiterite, and Sphalerite.
TELEVISION: Includes aluminum, copper, iron, nickel, silica, rare earths, and strontium. 10. STEREO: Includes gold, iron, nickel, beryllium and petroleum products.
While extracting gold from electronics is not without its challenges, it can be worth it for individuals looking to recover valuable metals and reduce e-waste. However, following safety precautions and using personal protective equipment when handling hazardous chemicals is essential.
The processors and connectors in computers, tablets, and smartphones use gold. You can also find gold in televisions, gaming consoles, printers, or essentially anything electronic.

Depending on the model of your TV and what condition it's in, you can expect to earn very little trying to sell a broken one. Some places will buy old appliances for scraps and parts, or with the intention of fixing and selling it on, but you won't earn enough in most cases to make the effort worth it.
Gold is used in the manufacturing of SIM cards due to it being a very excellent conductor of electricity. Other than this, it is also very durable. However, each SIM card contains very little amount of gold, and you need thousands of SIM cards to be able to extract a few grams of gold.
Gold-bearing circuit boards are increasingly used in appliances like microwaves, air conditioners, refrigerators, and kitchen stoves. A good rule of thumb is: The more technological features that an appliance has, the more likely it is to contain small amounts of gold.
Circuits in modern CPUs and Laptops weigh around 100 gm so you can expect to extract 0.150 grams of Gold. Additionally, the wires and connector pins have gold which will amount to another 0.070 gram and another 0.090 grams for gold plated contacts.
Magann: A PC circuit board, where the gold is, weighs about a pound. If you had a ton of those boards, you should have 5 troy ounces of gold.
The safest way to extract gold from rocks at home is to crush the rocks. However, you might use mercury to extract the gold if you're able to obtain some, though this is dangerous. While both mercury and cyanide can be used to extract gold from rock, it's hazardous to both your health and the environment to use them.
“A ton of electronics scrap should contain about 12 ounces of gold . . .”
Motherboards – the biggest circuit boards inside both laptops and desktops – often contain the “mother lode” of gold in used computers. Their edges have gold contacts and connectors where wires slide on.
How much gold is in a computer hard drive? It is possible to find gold plating in small traces, not only in hard drives, RAM memory sticks, but in many other components of desktop or laptop computers. The exact amount can vary around 0.3 gram of gold worth around $20.
Yttrium, europium, and terbium phosphors are the red-green-blue phosphors used in many light bulbs, panels, and televisions. The glass industry is the largest consumer of REE raw materials, using them for glass polishing and as additives that provide color and special optical properties.
Plasma and LED TVs contain heavy metals. Metals such as cadmium, mercury, lead, and copper present health risks to both humans and the environment.
For instance, CRT TVs have more gold than newer LED and OLED TVs. On the other hand, plasma TVs are made with more silver than gold. TVs do not contain that much gold. Cheap TVs might also have gold plating rather than real gold in their parts.
