A cathode ray tube typically is not repairable. It is like a light bulb in that the filament may fail. If that happens, you are out of luck. If the picture is dim, a transformer used to be available from Radio Shack and other electronics suppliers, that will boost the filament voltage and increase the brightness of the picture temporarly. That is the only "repair" possible other then replacement. If you are sure the problem is a bad CRT and you have a black screen..you are out of luck for repair...

What does cathode ray tube mean?
A cathode ray tube is what was used in televisions and computer monitors before the advent of the LCD, LED, and Plasma tv screens. They are big, bulky, and very heavy. They are a vacuum tube, with an approximately flat face, on the inner surface of which is deposited a phosphor. When electrons from the cathode asembly reach the phosphor, they cause it to glow at that spot.

What technology is used in the original-style monitor?
Lcd ***************************************** Older monitors (original-style?) used cathode ray tube (CRT) technology, were heavy, and took up a lot of desk-space.
What is horizontal and vertical amplifier in cathode ray oscilloscope?
The horizontal and vertical amplifier in the cathode-ray oscilloscope are deflection plates. The horizontal amplifier causes the beam to be deflected horizontally at a rate that is uniform. The vertical amplifier causes the beam to deflect vertically.
What is cathode ray tube color display?
CRT (Cathode Ray Tube) monitors were a type of display system, often used for both computers and televisions. CRT monitors are generally those "fat monitors" that you may have seen before (and might be using one right now). CRT is becoming deprecated with the newer method of LCD (Liquid Crystal Display), the method behind "thin" monitors and most of the newer television sets (however, some of the newer television sets use methods similar to LCD but not exactly the same - e.g. Plasma screens and Light Emitting Diode displays)
What following piece of equipment was used by jj Thomson to find electrons?
JJ Thomson discovered electrons using a cathode ray tube.
What is the full meaning of CRT in computer?
A "CRT" is a cathode ray tube. An old style computer monitor (not computer).
What is the flow of a cathode ray inside a cathode ray tube?
Electrons.
Why television are also known as cathode ray tube?
because cathode ray tube is the heart of the television.
Who first invented the cathode ray tube?
The cathode ray tube was invented in 1897 by Ferdinand Braun.
He conducted the cathode-ray tube experiment?
J.J Thomson conducted the cathode-ray tube experiment in 1911.
When did Cathode ray tube amusement device happen?
Cathode ray tube amusement device happened in 1947.
Which of these appliances uses cathode ray tube - electric fan refrigerator or rice cooker?
None of these appliances use a cathode ray tube. Older type TVs used a cathode ray tube, its common name was the picture tube.
How was the Cathode Ray Tube Amusement device invented?
Cathode ray tube amusement device was created in 1947.
Who discover the cathode ray?
The cathode ray tube was not discovered it was invented by Ferdinand Braun
What is the negatively charged electrode of a cathode ray tube?
The negatively charged electrode of a cathode ray tube (CRT) is the cathode. The tube is a cathode ray tube, and electrons stream off the cathode, are accelerated across the evacuated space and "directed" either electromagnetically or electrostatically, and then strike the phosphor coating on the positively charged anode at a "location" determined by the "directing" elements.
What is a cartrode ray tube?
Probably a mis-spelling of "cathode ray tube".
