Its showing signs of inverter malfunction. I would suggest that you check the status of the connectors going from the power supply to inverter and inverter to the backlight. Just unplug and replug them to see if the situation improves and let me know.

My mytouch 4g lcd backlight is dim but it gets brighter when i plugin the charger, is it the lcd? Or the connector to the lcd.


I'm not sure what a Mytouch is but on laptops if you don't have the power cord plugged in the display is normally dimmer or darker to preserve energy because it is running off the battery. You can make it brighter to some degree by pressing the correct keys on your keyboard. Once you plug the power cord in, laptops automatically display a brighter screen. This is all normal protocol.

The dashboard lights on my 2005 highlander are dim, how can I fix this.


I belive the dimmer switch for the dashboard lights are located left of the speedometer. It looks like an odometer switch. Turn it to the right and that should make the instrument cluster and lights brighter.

I hope that helped. If you have more questions about this just ask.

Dim monitor


5 years old, lamps are good for about 50 000 to 60 000 hours of life you would have to do the math based on average number of hours per week/month and see where your are, several things to check initially are inside look for blown capacitors, you can find images all over the net Google "blown capacitor image" and you will see what to look for.
Next could be inverter failure as they get old and work pretty hard. Last the ccfl lamps may be dieing of old age like the florescent lamps in buildings, they get burnt at each of the ends and have a hard time lighting up.
let me know what you find.

Are you using vista or xp?..The laptops to conserve power will dim the screen , you can , however, change it to brighter by pressing the "fn" key which stands for "functions"key. while pressing that, you should have another set of keys either to your right or obove your left finfers with the symbol fo a sun with arrows pointing up and down..press the fn and tap the up arrow key to increase the brightness.

Let me know if that works
