Is this an LCD type of monitor or CRT? either case, there's a problem with the horizontal IC. My best solution for this case is to have the unit serviced by an authorized personnel as meddling with the internal circuits of the monitor is dangerous.. Have them estimate the price for repair, if it costs too much... better buy a new one.


For CRT type of monitors: try degaussing, this feature can be found on the OSD (On Screen Display). This can be accessed by pressing Menu on the monitor buttons.

Hope this helps!

Just white screen with blue border


That normally happens because of the static electricity that builds up on the system board of your machine. This might be a result of sliding the laptop on the bed or carpet which make the static electricity to build up on the machine. Remove the battery, remove the power source, and remove any cd from the CD drive and hold down the power button for at least 2 minutes just to drain the static electricity out of your system

Monitor no raster power has been ok


Hello,

The screen is blank with no raster at all. There are indications that the channel numbers are changing in the display. This indicates that some of the low voltages are present but these may be derived from the standby supply.
Assuming there is no deflection and no High Voltage, you either have a low voltage power supply problem, bad start up circuit, or bad horizontal output transistor (HOT) or other bad parts in the horizontal deflection.

Check for bad fuses.

(If you have High Voltage as indicated by static electricity on the front of the screen and you hear the high pitched whine of the horizontal deflection when it is turned on, then the following does not apply).

Use an ohmmeter to test the HOT for shorts. If it is bad, look for open fusable resistors or other fuses you did not catch.
Assuming it is good, measure the voltage on the collector-emitter of the HOT (this is safe if there is no deflection). You should see the B+ - probably between 100 and 150 V.
If there is no voltage, you have a low voltage power supply problem and/or you have not found all the bad/open parts.
If there is voltage and no deflection (no high pitched whine and no HIGH VOLTAGE), you probably have a start up problem - all TVs need some kind of circuit to kick start the horizontal deflection until the auxiliary power outputs of the flyback are available. Some Zeniths use a simple multivibrator for this - a couple of transistors. Others power the horizontal osc. IC from a special line-derived voltage. The multivibrator type are sometimes designed to fail if someone keeps turning the set on and off (like kids playing) since the power rating is inadequate.
Test the transistors if it is that type with an ohmmeter. If one is shorted, you have a problem. The usual way a TV service person would test for start up problems is to inject a signal to the base of the HOT of about 15.75 kHz. If the TV then starts and runs once this signal is removed, the diagnosis is confirmed. This is risky - you can blow things up if not careful (including yourself).

If you hear the high pitched whine of the deflection and/or feel some static on the scree, confirm that the horizontal deflection and high voltage are working by adjusting the SCREEN control (probably on the flyback). If you can get a raster then your problem is probably in the video or chroma circuits, not the deflection or high voltage.

hope this helps......

What causes vertical lines on screen, some lines are thick and some are thin and appear over the task bar, they are across the entire screen.


They are static lines. They can be caused by a variety of reasons, damage to your monitor, damage to your vid card (perhaps it was got a little too hot?), ive seen this issue also with overclocked, try resetting to defaults if so. Also try reinstalling/updating your current display drivers. If you have an integreated video card it could be that your motherboard got hot and perhaps damaged it. If you have a spare vid card or something else you can hook up to try, and it still has the static lines, then it is your monitor for sure.

Monitor has many horizontal lines flashing across the screen


Yes your monitor can be fixed by an electronical expert! Is not so big problem but you can do nothing without an expert! The fixing-cost is not much! Is just sync problem! If this help you, rate me! Thx.

Sounds like the LCD has sustained physical damage. Replacement is the normal solution.

A big white vertical static band appears as soon a i turn on the power


Some of the transistors or the connection to the panel inside the monitor are damaged. There is no absolute fix for this problem.

You can try pushing on the bezel (NOT ON THE SCREEN) of the monitor at the edge of the screen directly at the lines and you may be able to push the connection back together well enough that the line goes away, but usually in desktop monitors the bezel is too rigid to allow you to put any pressure on the connections at the back of the LCD panel.
