CRT monitor screen is out of focus.text and other images looks blurry


This kind of symptoms can be correct by the focus adjustment at the flyback transformer. FBT mostly has two control knob (Focus and Screen), focus is usually at the top one like in the sample picture below.


Open the back cover of your unit and then locate the FBT. Power on the unit and try to adjust the focus knob.

If the symptoms can't be cured by the this step, this is an indication that the CRT socket is already faulty. You have to replaced this parts and then make some adjustment at the focus knob of the FBT and your unit will back to normal again.

M50lmd15x sony monitor focus problem

On the flyback transformer or FBT you can see two to three adjustment knob namely focus and screen adjust the focus knob slowly clockwise or counterclockwise until you get your correct focus adjustment you should view it while the monitor is on. Be care not to touch other component or wire.

Also be aware coz it has plenty of nasty voltages inside it. If you don't have experience and knowledge how it works i strongly suggest not to do it. Have the technician do it for you it is minor repair if it still can be adjust.

Fuzzy screen, not a flat screen.

TFT Monitor fuzzy display problems are almost always caused by one (or more) or the following issues:
  • Wrong display resolution. As mentioned elsewhere, TFT Monitors must be configured to use their Native Resolution in the PCs display settings. Failing to do this will always cause the display to be fuzzy or blurred - or to have jagged edges on diagonal lines and a 'lumpy' looking display.
  • Poor adjustment. If the display resolution is correct, then the monitor has to be correctly adjusted to get the best picture quality. This is usually only an issue with analogue monitors. If the digital (DVI) input is used, then further adjustment of the monitor should not be required. Initially, the monitors "Auto-Adjustment" can be used to try and improve the display quality. This is best used with a program producing a test pattern of vertical lines, with a single pixel white border showing the exact edge of the screen. Given this, most monitors will auto-adjust perfectly well. If the display is still not perfect, a very slight manual adjustment will usually achieve the expected quality.
  • Poor quality cables. Monitors are susceptible to signal degradation from either poor quality or excessively long signal cables. Also, joining or extending cables is likely to cause ghosting effects on the display, usually seen as light and dark vertical lines.
  • Faulty graphics cards or other component. In most cases upgrading the driver ill resolve this issue. If none of the above suggestions work then get me the brand and model number of your graphicscard and we will update the driver.

LG 700E monitor gives a blurr vision

open unit, adjust focus pot on flyback, may have 2 focus pots.
do both until satisfied.

If the problem varies with temperature (on time), then you may have a failing flyback.

Blurry screen

There is a focus adjustment inside on a part called the flyback transformer. It's located toward the back of the circuit board, and you'll know which part it is by the red cable going from it to a connection on the picture tube. The flyback generally has two small adjustment knobs on it. The focus knob is the upper one. Slightly turning this one way or the other may improve the focus a bit, but usually a sudden loss of focus means either the flyback or the picture tube has failed. Either of these is cause to treat yourself to a new monitor. You can buy 17-inch flat screens now for less than $150 at regular prices, and sometimes you'll catch a good sale at the office stores.

If you choose to try the focus adjustment, BE VERY CAREFUL!!

1) You have to remove the back of the monitor and work with the power on. Parts inside, especially the picture tube, can give you a very nasty shock AND EVEN KILL YOU.

2) Be very careful where you are putting your fingers when working on a live set. Make sure you have a safe grip on the adjustment knob first, THEN look at the screen while you adjust it. Don't go blindly reaching around.

Problems with screen

try these options, follow their order, it goes from the easyest and on: 1. every screen has maximum resolution, maybe the resolution you pick is higher than screen possibilities. 2. this may also be a resault of computer not recognizing screen. check windows defenitions, make sure windows recognizes the exact model of your screen. 3. reinstall drivers, reboot. 4. if problem is in hardware, you have to find what part is causing the problems. try connecting the screen to a new computer, try another cable, etc.
