Tatung v37mcgi I have a problem when switching on the TV. Every time I switch it on the screen lights up for only 5 seconds even the picture could be seen,but then the screen turns black. The sound will remain only the vision is lost. Can any one tell me what is wrong and what part can be replaced to have it working again.

Hi Rahni, It's a very common problem. LCD's use four small Cold Compact Fluorescent bulbs to back light the display. (thats what gives the LCD it's brightness allowing you to see it) The inverter board runs these lights and when they go bad they will typically show symptoms like you have or the monitor power light comes on and you have either no display or a very dim display. If you ever have one that has no display but the power light is on you can check by shining a flashlight directly into the LCD from the front (right into the screen) if you can see an image then it's either the inverter board (most likely) or the CCFL bulbs have gone bad. The inverter board and CCFL's are replaceable. Good Luck, El Duderino

This looks to be a power supply fault - the inverters for the backlights are built into the power supply (Delta Electronics, model no. ADP-40AF).

Simplest solution may be the screen resolution settings are set higher than the monitor's capabilities. Try lowering the screen resolution and refresh rate in the display properties or try booting to safe mode (press F8 when the Windows splash screen first appears) and see if the LCD will display the windows desktop. It that works, check your video drivers and the screen resolution and refresh rate settings.
If the monitor has the problem in safe mode and/or if lowering the screen resolution and refresh rate don't help then I suspect the a problem similar to one some Dell 17inch LCDs have. On the Dells It is usually caused by a defective voltage regulator transistor in the backlight inverter circuit. Troubleshooting that problem should only be attempted if you have experience at repairing electronic circuitry since it will involve testing individual components and soldering.

I had a similiar issue that caused all my Microsoft applications to zoom out to 500%. It also caused PDF documents to shrink and go the the last page. The issue was caused by the Intellatype software that came with my ergonomic keyboard. The issue was resolved by disabling the zoom feature of the sofware on the zoom tab.
