problem in vertical section.

1. Solder the vertical ic

2. vertical ic supply capacitor problen.

Hi,

Try checking B+ coil , may be the coil have shorted .

Happy trying

Is your monitor by any chance sitting next to unshielded speakers or anything else which could generate an electomagnetic field? You can get some terrific colour shifts with these items. If you do have anything like this put some distance between them and the monitor. Also the auto degauss coil circuitry could be faulty in the monitor. Take it to a repair shop and ask the tech to degauss the tube and see what difference it makes. If it fixes the problem get him to check the degauss system. Don't try this yourself. There's lots of voltage running around inside a TV. Fix don't Fry BMW

The monitor may not be able to handle the settings of the video adapter. If you boot into safe mode (tap F8 key as the computer starts), does the display appear correctly? If so, then you just need to turn down the settings (resolution, color quality, frequency) to the lowest possible settings. If the display still appears wrong, then it may be something wrong with the monitor. You can try connecting the monitor to another CPU and see if you can replicate the results.

It is the problem of video amp. ic plz chage it.If only red colour is miss then check red driver transistor and cable

Through my past experience I mwould remove the solder point at the input power B+ line to primary winding FBT. If the HOT has shorted there will be no power.Straight to the point if you know where the HOT is , you can desolder the middle pin or collector of the HOT transistor. If you desolder the pin which result the power led light turn up. That indicates either FBT or HOT has shorted

Restart your system and press F8 .Run window in safe mode .Then do this by add remove option

check cable and resistor that is giving 2number pins signals to video amp. ic and driver of green signal.

Hi

Pls reinstall the drivers for the graphics card and restart the computer and check if it is working.
If it does not work, then download the original drivers from the computer manufacturer or the graphics card manufacturer 's website and install them. Make sure that you have uninstalled the drivers before reinstalling any drivers.
Also pls look for any updates for the graphics card.

check all fuses...if they are okay...chances are you have a bad component somewheres I.E. Capacitor or Transistor, or Resistor

hi there, power supply prob., test first the fuse, then the rectifier diodes, the regulator and resistors. do some check up at the power supply section. ty
