What can printed circuit boards be used for?
PCB or printed circuit board are copper clad that are chemically etched to establish connections with parts installed on it making it a working circuit Today, just about every electronic appliance in your home contains a printed circuit board of some type: computers, printers, televisions, stereos, musical instrument amplifiers and synthesizers, digital clocks, microwave ovens, telephone answering machines and even cell phones. The "motherboard" in a computer is the main printed circuit board that is the heart of a computer. Other circuit boards inside a computer performs functions such as RAM (random access memory), power supplies, modems and video "cards."
How does a circuit board work?
A circuit board or more precisely a printed circuit board (PCB) is a mechanical structure that provides support for mounting electronics and electrical components and connecting them with conducting traces or wires. PCBs are designed to perform a specific electrical or logical function. So what and how a circuit works will depend on its design. e.g. a circuit board in a TV processes audio/video TV signals. An audio amplifier circuit board amplifies and makes audio signals louder. Similarly various circuit boards in a Personal Computer perform different functions e.g. PC mother board, TV tuner card, USB/Firewire Card, Graphics cards are all circuit boards and perform different tasks. All of them need power (typically a DC voltage) for various components and circuits to work.
Why does my LCD TV have no power all of a sudden?
Could Be a fuse on the Circuit Board or The Power Supply Capacitors are bad.
What Industries buy circuit boards?
Basically anything that needs a plug or a battery.to run uses a circuitboard. Industries that manufacturer there own products medical , communications, video gaming, computer, television, automotive, power generation, and space technology are just a few industries of the many that use circuitboards. For product examples your cellphone, alarm clock, tv, radio, sonar fish gun, health equipment, stun guns, xbox, computers, and your cable or satellite DVR. Circuitboards are used far more often than people realize. The common name for circuitboards is printed circuit board or printed wire board. For more information go to www.circuitboards.com. and go to the terms/glossary page.
Can a computer be connected to cable HDTV?
Yes, when equipped with a TV adapter, which is commonly a circuit board inserted into extension slot of the mainboard.
1992 Lincoln mark vii lsc amplifier powers up without sound to the speakers?
MY 92 LSC HAD SAME PROBLEM , DEALER COULD NOT FIX, TOOK OUT AMP AND BROUGHT TO TV/ELECTRONICS REPAIR SHOP, PRINTED CIRCUIT BOARD WAS CRACKED, THEY REPAIRED/REPLACED....BELIEVE IT WAS APPROX $125.00 DOLLARS.........
How is PCB used?
To hold microchips, capacitors, transistors, MOSFETs, wiring and more, naturally! PCB means Printed Circuit Board. It's that green (Occasionally other colors) board with all the squiggly lines and technologically looking stuff on it.
How do you fix my RCA TV when all i get for video is a single white horizontal line?
Your vertical output amplifier has probably gone bad. It's a circuit board level repair.
Capacitors in a tv?
what about them? You didn't ask a question so we can't answer it
What is a printed circuit board that you can insert into a computer to give it added capabilities?
Although you could be referring to many different things, the most likely thing is a PCI card. These are PCBs with a specific interface slot that can add specialty functions to a computer. They are commonly used for network interfaces and TV tuner cards. See this page for more info: http://en.wikipedia.org/wiki/Conventional_PCI
What materials are used in making televisions?
In an older CRT television sets steel, copper, lead, tin, aluminum and gold would be likely metals. Steel would be used for certain electronic parts, screws and brackets. Lead and tin are used for the solder that is used to connect the electronic parts to the PC (printed circuit) board. Solder is also used to put a thin coat on the surface of the traces (flat wires) on the PC board. Copper is used for certain electronic parts, PC board traces and wires. Aluminum is used for brackets and heat sinks. Gold is used in very small amounts inside of ICs (integrated circuits) to attach the silicon integrated circuit to the leads that are used to attach the IC to the PC board.
My Samsung TV is power cycling after the main board was replaced. Why is the new board not working?
It could be due to a fault on the power supply board (Bad Caps). Assuming the 'main board' refers to the main processor board.It could be due to the new board not being an exact replacement.There could be a short circuit on the main board, taking one of the supply lines down.The plug in cables may not be seated properly or in the wrong socket.
