If your LCD TV or monitor has stopped working, or is displaying one of the following
symptoms, then it's a candidate for some new capacitors
- Flickering screen
- Screen image disappears after several seconds
- Dim screen
- Slow start
- Power LED on, but no picture
- Unusual colors and/or lines
The primary cause of LCD TV and monitor failure is caused by faulty capacitors. You can
examine the capacitors in your LCD TV or monitor and actually see if they are bad.
If they appear bulged on top, then they need to be replaced.
New capacitors will solve a host of problems in LCD monitors and TV's and will extend the life
of your monitor or TV by several years.
Take it to a repair shop.
You need to change the resolution on the laptop for the TV.
Right click on your Laptop's desktop screen, and select Display properties, or Properties (depending on what O/S you are running)
Select the Settings tab if you are in XP, or select Screen Resolution if you are in Vista or 7.
You should now see the settings for setting the Display resolution for your Native Monitor and your LG TV (the TV must be plugged in to your laptop in order to see it in the Display resolution settings)
Set your resolution to a lower resolution, e.x. 800x600, 1024x768, etc.
use a vga to vga cable and a 3.5mm jack to 3.5mm jack lead like these
you will then need to to switch to pc input and your computer should display on the tv, if your using the tv as a secondary display from your computer. I.E. you already have a monitor connected or its a laptop you will need to go into display properties in your control panel and click on settings and then enable the second display.
You may need to use the S-video cable for video. Make sure video mirroring is disabled on the powerbook. Also, make the external monitor the primary display by dragging the menu bar to it in Displays preferences (Mac OS X) or the Monitors control panel (Mac OS 8 and 9).
Go into your control panel.
There will be a picture showing 2 screens.
Select the 2nd screen, and lower resolution to it's minimum.
Apply and test.
Slowly increase till you find what your happiest with.
Worked for me using a ASUS laptop and LG60'plasma.
I am assuming that you have installed the cable to the appropriate jack/connectors on the back of the TV and that of the PC.
If you are using a laptop, you would need to press on the Fn + F? keys of the laptop to cycle through the different
settings such as: laptop's display only, laptop & TV displays and
TV display only. The F? key would be one in your laptop designated to
engaged/enable external monitor (TV). Normally, it would have a monitor
Please verify that your PC's screen resolution is 1366 x 768 or lower.
If you are using a desktop, you need to engage/enable the dual/twin view in Display Properties. Additionally, the TV must be powered on first before the desktop is booted.
Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.
