Notes on the Troubleshooting and Repair of Computer and Video Monitors

Monitors, monitors, and more monitors In the early days of small computers, a baud teletype with a personal paper tape reader was the 'preferred' input-output device meaning that this was a great improvement over punched cards and having to deal with the bozos in the computer room.

Small here, also meant something that would comfortably fit into a couple of 6 foot electronics racks! The earliest personal computers didn't come with a display - you connected them to the family TV.

You and your kids shared the single TV and the Flintstones often won out. The Commodore 64 would never have been as successful as it was if an expensive monitor were required rather than an option.

However, as computer performance improved, it quickly became clear that a dedicated display was essential. Even for simple text, a TV can only display 40 characters across the screen with any degree of clarity.

It was bright, crisp, and stable. This was really fine until the introduction of Windows well, at least once Windows stayed up long enough for you to care. All of these displays used digital video - TTL signals which coded for a specific discrete How to apply a sam splint of possible colors and intensities.

Both the video adapter and the monitor were limited to 2, 4, 16, or a whopping 64 colors depending on the graphics standard. The video signals were logic bits - 0s and 1s. With the introduction of the VGA standard, personal computer graphics became 'real'. In principle, an analog monitor is capable of an unlimited number of possible colors and intensities.

In practice, unavoidable noise and limitations of the CRT restricts the actual number to order of distinguishable intensities for each channel. Note that analog video was only new to the PC world.

TVs and other video equipment, workstations, and image analysis systems had utilized analog signals for many years prior to the PC's 'discovery' of this approach.

In all fairness, both the display adapter and monitor are more expensive so it is not surprising that early PCs did not use analog video. Most of the information in this document applies to color computer video monitors and TV studio monitors as well as the display portions of television sets.

Black and white, gray scale, and monochrome monitors use a subset of the circuitry and generally at lower power levels in color monitors so much of it applies to these as well. For a fixed frequency workstation monitor, studio video monitor, or closed circuit TV monitor, only a subset of the possible faults and procedures will apply.

Usually, this refers mostly to the horizontal frequency as the vertical refresh rate is quite flexible on many monitors of all types. Multi-scan monitors sync at two or more distinct scan rates. While not very common anymore, multi-scan monitors may still be found in some specific applications.

If you are considering purchasing a monitor or have one that you would like to evaluate, see the companion document: Performance Testing of Computer and Video Monitors.

Monitors designed for PCs, workstations, and studio video have many characteristics in common. Modern computer monitors share many similarities with TVs but the auto-scan and high scan rate deflection circuitry and more sophisticated power supplies complicates their servicing.

However, handheld equipment, laptop computers, and the screens inside video projectors now use flat panel technology, mostly Liquid Crystal Displays - LCDs. These are a lot less bulky than CRTs, use less power, and have better geometry - but suffer from certain flaws.

As the price of LCD and other technology flat screen technology decreases, such monitors will become dominant for desktop computers as well and CRT based monitors will eventually go the way of dinosaurs, core memory, and long playing records that dominated their respective industries for decades but eventually yielded to fundamentally new technology.

However, there are still problems with low cost, at least LCD monitors.

First, the picture quality in terms of gray scale and color is generally inferior to a decent analog monitor. The number of distinct shades of gray or distinct colors is a lot more limited. They are generally not as responsive as CRTs when it comes to real-time video which is becoming increasingly important with multimedia computers.

This is partly due to the response of the LCD material itself but also a result of the scan conversion that's needed for non-native resolution formats.Oct 20,  · Use a sugar tong splint for fractures of the humerus.

Use a long-arm posterior splint for elbow injuries. Short-arm splints may suffice for distal forearm and wrist injuries. Use a thumb spica splint for thumb injuries. Splinting and taping one finger to another, one leg to another, or an arm to the torso can effectively immobilize a limb%(13).

SAM Splints are also used on the International Space Station. The SAM Splint is a compact, lightweight, highly versatile device designed for immobilizing bone and soft tissue injuries in emergency settings.

It consists of a layer of inch strips of soft aluminum, with a polyethylene closed-cell foam coating. Apply the SAM splint to the forearm so the bend is at the elbow and the fracture is between the two sides of the splint.

Adjust the shape of the SAM splint to conform to the limb, if needed. APPLY THE SAM SPLINT TO A FRACTURE of the FOREARM, WRIST, LOWER LEG, OR ANKLE x Question: – I am going to secure the SAM splint using these cravats. Medical Splint - Sam Splint 2 pack - Perfect to Carry 36" RollThe original blue and orange SAM Splint is acclaimed by emergency care providers and outdoor enthusiasts worldwide (and even beyond the Earth, on NASA space shuttles).

A first aid class/briefing that teaches how to apply a SAM splint to a fractured limb. You have already completed a performance examination on splinting a fractured limb using an improvised splint. Your combat lifesaver aid bag contains a rolled up splint, called the SAM splint, which can be used to immobilize certain fractures.

SAM recommend supporting the ankle as a 'stirrup' under the heal; this does not reduce flexion or extension of the foot. Fully open the splint and position the centre of the splint under the arch of the foot. Remove the insole of the footwear and place it between the foot and the splint.
