EGR VALVE IS KNOWN TO GET CLOGGED UP, SEVERELY ! MAP SENSOR MAY BE ACTING UP ALSO, ALL SENSORS WORK TOGETHER, IF ONE STARTS GOING BAD THE OTHERS TRY TO ALONG WITH THE COMPUTER TRY TO COMPENSATE, YOU ONLY NOTICED IT AFTER FREEWAY, BECAUSE @ HIGHER THROTTLE, IT WILL NOT SHOW UP, THE TRUTH CAME OUT WHEN YOU GOT OFF THE FREEWAY ! VERY CONDISENDING , ESPECIALLY WHEN YOU THOUGHT YOU WHERE HELPING TO BLOW OUT THE ENGINE TO RUN BETTER,. YOU SHOOK SOMETHING LOOSE. BETTER AFTER FREEWAY, THEN ON IT.

Your new moniter may not be compatible with your computer. I have an Emachines that won't take a flat screen. I have to use a big bulky moniter because it says not connected even thought the hookup fits the back of the tower. That might be your problem. Did your old moniter work correctly?

Sounds like an issue with the backlight in the monitor. Usually the backlight is built in to the LCD panel so there really isn't a way of fixing this unless you replace the panel.

Get Moniter Speakers Working


Hello First of all you need a sound card on your computer with a Spk. (Speaker) or Phones (headphones) Out Jack it might be a symbol of a small speaker or headphones. You have to be sure you are getting a actual sound output signal from this sound card too. If the sound card is not working your moniter speakers would not have a signal to drive it. You also need a 1/8" Stereo 2 male stereo plugs on both ends, one end plugs in back of moniter other plugs in back of computer like I mentiond above. Make sure your Mute button is not selected on your computers volume button usally at bottom right of screen. Make sure the volume buttons are up to aprox 3/4 up also. Then for last on the moniter look in the menu i think you might have to keep pressing the menu button but i kind of forget now but its a Spk setting and volume setting in this speaker setup within the moniter as well make sure this is turned on and set at a higher volume level as well. Thats about all I can say without taking the moniter apart and checking the jack and wires and speakers. I would suggest you take it to a electronics or a tv repair or computer repair person to go any further then this. Hope you take time to read all of this I tried to put every step in here to help anyone out with this problem. Thanks for reading. Ken T
