20 Most Recent Toshiba Tekbright 15" CRT Monitor Questions & Answers

The problem is a bad picture tube, or a defective CRT board that attaches to the back of the picture tube.

Most CRT displays sold for use in the US & Canada (and probably everywhere else for that matter) require AC. This is because AC is the most popular mode as it is easily stepped up for long distance transmission and down for use in commercial, industrial and residential uses, by your local utility. Additionally, AC is affected by losses or resistance differently than its DC counterpart. All of these (and more) reasons reduce the cost of providing electricity to buildings and homes.

If the utility generated and delivered DC, then electrical devices would be set up for DC connections. Since there is 60 Hertz AC at your outlet, the CRT makes use of it, and converts it to whatever the internal requirements are. Stepping the voltage down and / or changing to DC (inside or outside the cabinet) allows for many parts of the circuit to work directly - and AC of nearly any frequency (not just 60 Hertz) can be produced as needed with electronic circuits inside the cabinet.

Colors, shading, etc on CRTs are the result of an electron gun at the back of the CRT. The gun fires electrons at tiny red, green and blue phosphorous targets on the front of the screen. When the target is struck, the phosphorous glows briefly. If the phosphorous is behind a red mask - it glows red (the same holds tru for green and blue). This same process occurs for each of the thousands of colored target on the entire screen, 60 times per second.

This is simplified explanation - there are other parts of a CRT. There are circuits that create magnetic fields the direct the electron both left and right in addition to up and down the screen. Without these circuits, there would be just one dot glowing on the screen. There are circuits for refresh rate, demagnetizing, brightness, contrast and more.

I hope this provided a good starting point for you and found it helpful.

well its the problem with your switch!
because when you click it, doesn't lock.

You just bought a new power supply for the monitor? Did you set the B+ voltage to the correct settings. Rebuilt power supplies for CRT monitors are not set correctly at the factory. Use your schematic to determine the proper B+ and then set this under load.

If your Toshiba Strata CHSU40A3 phone system is not displaying anything and there is no dial tone, there could be a few reasons for this issue. Here are some troubleshooting steps you can try:

1. Check the power source: Make sure the phone system is plugged into a functioning power outlet and the power adapter is working correctly. You may also want to try plugging it into a different outlet to see if that helps.
