Hello

Click the "Start" tab in the lower left hand corner of your Toshiba laptop's screen. From there, go to Settings and wait for the column to pop up. Scroll up the column and click on the "Control Panel." While the Control Panel window is open, click on the "Display" icon.

Press the tab labeled "Settings" while in the Display Properties window. Locate and click the "Advanced" button.

Click the "TwinView" tab from the window that automatically pops up at the end of Step 2. While in the "TwinView" tab, ensure that "Display" is set at "TwinView Display 1: Digital Flat Panel."

Locate and press the "Output Device" button. Click on "Color Correction" and adjust the brightness of your Toshiba laptop.

Hi, We have a Toshiba rear projection tv model 46WH08G which wont turn on. by this we mean that the red power led light is on and weve noticed that the green led light alongside is flashing, which has a...


It sounds you need a new Projection Lamp; they usually last for 2000 hours or more. The led blinking is the lamp warm-up period and it fails now, if you replace the lamp be careful very static sensitive and blow the dust out with air while the TV is open. Hope this Helps.

I just moved my 42in. Toshiba rear projectiom Tv from my basement to the upstairs and now my convergence is off. The red tube cross is low on the manual adjustment and will not go up to the other colors.IT...


It sounds like you jostled the red CRT gun when you moved the set. If the convergence adjustment still moves the red cross hair the the circuitry is okay. Your red gun needs to be realigned. This requires a service call unless you want to attempt it yourself. It is fairly involved and requires some specific tools as well as using the service mode on the remote to reset the convergence after the gun is repositioned.

Hi my monitors screen becomes yellowish.all colour effected y dis


Hi,
Do you have a CRT monitor?
Have you tried to adjust the color on the monitor?
How is it connected to your computer?
It sound like one of the guns on you monitor died. But there is some testing you should do first.
If it is a CRT monitor and it is connect your computer properly. First thing to do would be to replace the cable and or try a different monitor that you know works.
To confirm try adjusting the color. If that does not work, if it more purplish it is the green gun, if it is orangish it is the Blue gun. That would be cause by a failed gun or driver.
If the gun is gone it is best to get a new one. It will save you money in the long run.

Thank you...

Sony trinitron tv kv type


The screen voltage adjustment should be on the back of the high voltage multiplier. It should be marked as "Screen", or "G2". Next to it, is the "Focus" adjustment.

Some models of Sony sets have two focus adjustments. This is for H and V focus.

When increasing the screen voltage will usually increase the wear factor of the electron-gun assembly in the CRT. This is because it is increasing the screen bias current.

When increasing the screen bias, the brightness will increase a little. When the CRT is weak, this may produce visible retrace lines more so than on a good working CRT. This is because the excessive screen current will stop allowing the electron-gun assembly to work at its proper cut-off level in order to allow the blanking drive to bias it off during the retrace period.

Increasing the screen bias will usually cause a shift in the colour temperature especially in the low level gray colours. This is because the AKG reference for the electron-gun biases will be offset due to the differences in the electron gun performance characteristics change.

Colour issues


Sounds like your red gun may be shorted, Try adjusting the red gun down a little see it that helps.You can also switch the blur CRT socket for the red if your screen is still mostly pink then you know for sure its your red tube that needs replacement. If its mostly blue then you have a problem in the red drive circuit.

in Monitor CRT Red-Blue-green cathode guns are there.. Mixing of these colour we can get the original colour chrominace technique. if any of the colour gun is faulty we would get more REad or blue or green picture. Measure RGB voltages. you can verfify which gun is faulty. if then check RGB processing circuits. Else there might be problem Chrominance colour decoder system. Contact service centre
