GNR TS902 19 inch flat screen computer monitor with 3x4 aspect ratio
Difficult starting or completely dead:- (This is a 'Stock Fault' with these otherwise excellent monitors)
Check or replace the electrolytic capacitor C829 - type 1000MFD 16 Volt DC Wkg It sits on the PSU board next to an empty "C817" mounting point (which is for a device wired in parellel) so you can fit two smaller ones (of ~ 500MFD each) . . I suggest replacing it (C829) with a 1000MFD25 VoltDC Wkg type.
Also (very much less frequently) capacitors C802 - 470MFD 50V VoltDC Wkg and C819 680 MFD 16 VoltDC Wkg are faulty.
Check that the connection to the computer is tight. Check that the connection to the monitor is tight. Check the cable for any cuts or nicks. Have you tried the monitor on another computer? Have you tried another monitor on the computer? Update the drivers for your video.
The video resolution setting is done AT THE MONITOR DISPLAY PROPERTIE SETUP, not at the monitor. The video card driver is up to date?
What OS are you running?
If you are running Windows 7, you need to find driver for this model.
Seems that you have set the resolution on your graphics card to a
setting higher than the maximum resolution supported by your monitor. Try
to boot into Safe Mode & lower the resolution of your graphics
card. If not possible, go to Device Manager & remove the graphics
card from it, then reboot your computer. This will reset the resolution. You can then re-install your graphics card drivers & get it to work properly.
Did the other monitor have the same problem or was it ok? If it's just the one monitor, it may be on it's way out. It is very dangerous to open a monitor and try to repair it. Don't do it yourself unless you know exactly what you are doing. Have you installed anything new in your pc? What about seeing if there is an updated driver for the monitor? The monitor's website - support page - should have a driver update. See if that works. If you recently installed a graphics program, it could be a setting there that is messing things up.
I think this is the problem of blanking section change the horizantal and vertical blanking transistors.placed near eht.normaly 700 in series and connected with vertical output ic.if they are ok then change vertical output ic.
Hope this be of initial help/idea. Pls post back as requested, how things turned up or should you need additional information.
Good luck and kind regards.
